Power banks can be extremely dangerous. There’s an abundance of stories like this one (by IBTimes): ‘A Thai woman nearly found herself trapped in fire after her power bank exploded beside her while she was asleep.’
This of course makes you worried about the safety of power banks. But fear not, if you use your power bank properly, this wont happen. Using your power bank properly will not only be a lot safer, it will also prolong the power bank’s battery life. And a good place to start might be to stop charging it to 100%. Here’s why.
Quick Summary:
You Shouldn’t charge your power bank to 100% on a regular basis, preferably keep it between 20-80% charge
Don’t make a habit of leaving your power bank charging overnight, doing so can overheat the power bank.
Do the basics like: staying between 20-80% charge, not charging overnight etc. For optimal lifespan.
Lithium-ion batteries perform best between 20-80% charge, because anything above that causes excess stress and anything below might damage the internal chemistry.
Which is why you shouldn’t charge your power bank to 100%, as it will put a lot of extra stress on the battery. Which then in turn poses safety risks and reduces the lifespan of the battery significantly.
Also, don’t leave your power banks charging over night, unless it has extra safety features like overcharge protect. I’ve had a relative who’s phone battery caught fire and caused a house fire a few years ago, due to it being left to charge overnight. It might not be a power bank, but they’re both lithium-ion batteries.
So please, don’t make a habit of leaving it charging overnight. Maybe once-in-a-while is okay, but if it doesn’t have safety features like overcharge protect, it’s best to avoid doing it.
How you should use your power bank instead
Now you know that you shouldn’t charge your battery to 100%, you might be asking yourself: ‘What should I do instead?’.
Well one thing you can do right now is keeping it between 20-80% charge. Making sure that you stay within this reach will significantly improve your power banks lifespan.
According to Varta who’s one of the biggest battery manufacturer in the world: ‘Partial cycles can even prolong the lifetime of your Lithium-Ion battery.’ Or in simpler terms: a not full cycle, so not from 100% to 0% but for example from 80% to 20%, will actually increase the batteries lifespan.
Overcharge protect
As you might have heard, there is a new thing called ‘overcharge protect’, which is meant to be able to protect your power bank’s battery from overcharging.
It works by: ‘using the circuitry to detect when your device’s battery is fully charged and then stop supplying power to prevent any further charging.’ According to this article by brothers4change.com.
Basically, it just makes sure that when the device is fully charged, it will stop charging to prevent damage. Which makes it a lot safer to leave charging, however I still wouldn’t recommend it.
Tips to increase power bank lifespan
So now you know that you shouldn’t charge your power bank to 100%, here are some other tips to improve the lifespan of your power bank:
Don’t go below 20%, going below 20% might damage the internal chemistry. It’s not the end of the world if it does, but just avoid keeping it at 0% for long periods of time. As you might now there have been a lot of cases where batteries have imploded because they were stuck at 0% for so long.
Get a high-quality power bank, getting a high-quality power bank is going to be far more effective at increasing lifespan than any of the other tips. I know it’s expensive, but a good quality power bank will last 5 times as long as a bad quality one. Besides, it’s also a lot safer.
Keep firmware updated, this just makes sure that your power bank is working the best it can. Firmware updates often fix things like: bugs, improve battery management etc.
Doing this will already extend your power banks lifespan drastically, they’re the basics of proper power bank usage. They will make sure your power bank will last at least 2-4 years. Because, we all know how expensive new power banks are these days.
Conclusion
So my recommendation is to not fully charge your power bank, or at least don’t keep it at 100% for extend periods of time. This will only do more harm than good, because it puts excess stress on it’s poor lithium-ion battery.
Other than that, follow these basic tips for proper battery: update firmware, invest in a high-quality power bank, and don’t go to 0%. Again, it isn’t the end of the world if your power bank hits 0%, but it’s best to avoid it or at least don’t keep it at 0% for extended periods of time.

“Almost half a million power banks were recalled after Charmast (power bank brand) received several reports of injuries,” according to a story from last month by Gray News. None of us would want that to happen, but it’s a real possibility if you don’t have a quality power bank and good charging habits.
Finding the right power bank can be tough, but it’s worth the effort. Plus, isn’t it super annoying to replace your power bank after just a few months? Just adopting some simple charging habits like keeping your power bank between 50-80% and not charging your device and power bank at the same time will give you an extra 1 to 3 years.
Quick Summary:
A good quality charger will last about 2-5 years, depending on the make and model.
A low quality charger and bad charging habits, might pose a significant safety risk as well as lower your power banks lifespan.
Simple things like updating firmware and not going down to 0% or up to 100% charge will add another year of life expectancy for your power bank.
If you want the quick answer, it’s about 2-5 years for a good quality charger. However, this highly depends on the quality and capacity of the charger. Not to mention the way you store it, how you use it etc.
However, for good quality chargers, capacity is a good metric to make an estimate of your power banks lifespan. So here’s a table by Anker that shows how long your power bank will last relative to it’s capacity:
This shows that a longer capacity equals a longer lifespan. This is according to Anker because: ”[they have] more energy stored in them and can withstand more charging cycles”. Simply put, power banks with a higher capacity can last more charging cycles than power banks with less capacity
What effects a power banks lifespan?
There are a ton of things that affect a power banks lifespan, however there are a few that you should look at for. They’re the most common causes of premature deaths for power banks (R.I.P.). These are:
The capacity of the power bank. As I showed earlier, the more capacity a power bank has, the longer it will live. This is because they can store more energy which makes them able to withstand more charging cycles.
The quality of the components, this is of course extremely obvious but still worth keeping in mind. Quality components often come at a higher price, but they’re worth it in the long run if you can get more out of them.
How you use your power bank. Yes, if you use your power bank incorrectly, it can damage it’s battery life significantly. I’ll leave some more information about how to use your power bank correctly later in this article. But these are the basics to get you started: keep between 50-80%, avoid draining to 0% and avoid using your power bank while charging.
”According to research, excessive heat is the main cause of battery deterioration, particularly for lithium-ion batteries.” From an article by gp.batteries.com.
But there are a lot more things that effect a power banks lifespan like: environmental factors, for example in a story from 2023 by the Thai Newsroom where a power bank exploded due to the extreme heat in Thailand. But also damage, or even the humidity and altitude can cause power banks to overheat or corrode.
What can you do to increase lifespan?
So what can you actually do? Well there are a few things that you can do right now to improve your power banks lifespan. Applying these will give you an extra 1-2 years of lifespan.
Here’s a list of 4 things you can do right now:
Get a high-quality power bank, investing in a high-quality power bank is going to be worth the money. Especially if you have a really bad quality one right now. This can not only improve it’s lifespan, but also ensures your safety.
Don’t go to 100% or 0%, if you want your power bank to live longer, neither of these extremes are good. So instead, keep your power bank between 50-80%, this is recommended by experts because it reduces the voltage stress and avoids damaging the internal chemistry.
Keeping firmware updated, staying updated is always a good idea when trying to increase lifespan. Because firmware updates enhance battery management, fixes bugs, and reduces strain.
Avoid using the power bank while charging, doing this can create excess heat, which in turn will damage the power banks components.
Do all these things and you’re bound to get an extra year or two out of your precious power bank.
When to replace your power bank
If you notice that your beloved power bank isn’t how it used to be, you should maybe consider replacing it. Here’s a checklist of 3 of the main things you should look out for:
Of course, a little bit of slower charging after a year or 2 of frequent use is bound to happen. But, if it’s really getting to an annoyingly high amount, then you should swap it our for a new one.
Conclusion – How Long Do Power Banks Last
In conclusion, getting a high-quality power bank and some good charging habits will heavily increase your power banks lifespan, and in turn save you a lot of cash. Just doing the basics like updating firmware and not using your power banks while charging, will already be super beneficial and give you an extra few years.

Hate it when you’re portable charger chargers at 2 watts per hour? Well don’t worry, I’m here to break down the fast charging technologies in 2024.
If you’re tired of carrying around a clunky power bank that barely charges your phone halfway. Or maybe you’re simply curious about what makes some chargers so much faster than others, either way keep reading.
From GaN to Samsung’s adaptive fast charging, I’m going to go over everything you need to know in 2024.
Quick Summary:
USB-C is the best and most widely used cable for portable chargers, mainly because of it’s high speeds.
The different fast charging technologies are: USB-PD, Qualcomm Quick Charger, Samsung’s Adaptive Fast Charging and OnePlus VOOC and DASH Charging.
GaN chargers are the future of charging, being way faster then traditional silicon chargers.
Before we dive into all the different fast charging technologies, let’s consider why you even need a portable charger.
Imagine you’re out at a concert, in the middle of a hike, or running errands, and suddenly, your phone hits that dreaded 10% mark. Or you’re just chilling on your phone and your battery is draining faster than you can blink.
That’s exactly when portable chargers are your best friend. As someone who uses them all the time, I’m telling you I couldn’t do without them.
However, not all chargers are the same. Some charge faster, some are bigger, and some have cool extra features like wireless charging. If you’ve ever wondered why some chargers seem to top up your phone super quickly while others drag their feet, it’s all about the technology inside. So let’s break it down.
USB-A, USB-C, and Everything In Between: What’s the Difference?
To put it simply: USB-A is the older, slower standard, while USB-C offers faster charging and more power delivery. USB-C is now the preferred option among techy people like me. Mainly due to its compatibility with modern devices and ability to handle higher wattage for quicker, more efficient charging.
So let’s get into everything you need to know about these two and the confusing Volts, Watts and Amps.
USB-A – The Old Reliable (But Not for Long)
USB-A has been around for ages. You’ve probably seen this port on your old charger cables or laptops. It’s the big, rectangular one that fits into your device. However, let’s face it: USB-A is on its way out.
Sure, it’s reliable and works for a lot of devices, but it doesn’t charge as fast as the newer options. Ever wanted to plug in your USB-A cable to your laptop or charger and it didn’t fit? Then you tried again only to realize that you might have been right the first time and now have damaged the insides of your laptop. Yeah, I know what that feels like.
USB-C – The New Standard for Speed
USB-C is where the magic happens. It’s the new standard for fast charging, and it’s pretty much replacing USB-A across the board. Unlike USB-A, USB-C is reversible (no more fumbling with cables trying to figure out which side goes in), and it’s capable of delivering a lot more power – up to 100W! That’s right, USB-C can charge your phone, tablet, laptop, and even some gaming devices at lightning speeds. Plus, it works with tons of devices, so you don’t need a different cable for every gadget.
Here’s everything that I love about USB-C:
Reversible Design: Plug it in any way you like—no more fiddling to find the correct side.
Fast Charging: Delivers up to 100W of power, making it ideal for phones, laptops, and even some gaming devices.

To put it simply: If you’re buying a new charger today, USB-C should be at the top of your list.
Voltage, Amperage, Wattage – Wait, What?
Alright, before we dive into the really cool stuff (like GaN and Qualcomm Quick Charge), let’s quickly go over a few basic terms. You’ve probably seen numbers like 5V, 2A, or 30W on charging specs, but what do they actually mean?
Well here’s everything you need to know:
Voltage (V) is the force that pushes electricity through the wire. Think of it as the pressure that drives the flow of electricity.
Amperage (A) is how much current flows through the wire. It’s essentially the volume of electricity being pushed.
Wattage (W.) is the total power delivered. It’s a combination of voltage and amperage (W = V x A).
Basically, more wattage means faster charging, but your device needs to be able to handle it. A charger that can deliver 30W won’t magically charge your phone faster if your phone only supports 10W.
Charging Speeds – What’s Fast Charging All About?
Here’s where it gets fun. You’ve probably heard the term “fast charging” thrown around, but not all fast chargers are the same. Some charge your device in minutes, while others can take hours. Let’s take a look at the most common fast-charging standards.
1. USB Power Delivery (USB-PD)
If you’re looking for a charger that can seriously pump out power, look for USB Power Delivery (USB-PD). This charging standard is all about speed. It can deliver up to 100W of power! This means it’s not just good for phones – it’s also perfect for charging laptops and other power-hungry devices.
This isn’t how USB-PD cables actually look like, but I thought it was a cool representation.
USB-PD uses a smart negotiation process, meaning your charger and device communicate to find the optimal voltage and current. Which makes sure you get the fastest, safest charge possible.
Some of the newer iPhones, Android phones, and even laptops now support USB-PD, and it’s one of the best options for fast charging.
2. Qualcomm Quick Charge – The OG Fast Charging Technology
Next up is Qualcomm Quick Charge. This was one of the first technologies to really speed up phone charging, and it’s still going strong today. Quick Charge comes in several versions, with Quick Charge 5.0 being the latest & fastest, supporting up to 100W of power.
What sets Qualcomm Quick Charge apart is its ability to charge your device to around 50% in just 15 minutes. That’s impressive, right? If you’re always on the go and need a quick top-up, Quick Charge can be a game-changer. However, you’re phone must be able to support that kind of power. Not all phones will charge to 50% in 15 minutes with this.
3. Samsung’s Adaptive Fast Charging
Samsung has its own fast-charging standard, called Adaptive Fast Charging. It uses a similar approach to Qualcomm Quick Charge, offering 15W charging speeds for a quick power-up.
To make it simple, here’s a pros and cons table:
Pros✔️
Cons❌
Faster charging speed – Charges devices significantly quicker than standard charging.
Requires compatible charger – Not all Samsung chargers or cables support Adaptive Fast Charging.

4. OnePlus VOOC and DASH Charging
If you’ve ever used a OnePlus phone, you know their VOOC (Voltage Open Loop Multi-step Constant Current Charging) and DASH charging technologies are seriously fast.
VOOC can charge a device 50% in just 15 minutes! While DASH takes it even further with super-speed charging that can fill up a phone in around 30 minutes.
OnePlus has been a pioneer in fast charging, and their charging tech is still some of the fastest on the market today.
Gallium Nitride (GaN) – The Game-Changer in Charger Design
GaN (Gallium Nitride) technology allows chargers to be faster, smaller, and more efficient than traditional silicon-based ones. It enables powerful, compact chargers that deliver high wattage while managing heat. Which makes them ideal for fast, portable charging.
So here’s everything you need to know about this new charging technology:
Why GaN Chargers Are the Future
GaN chargers are faster and more compact than traditional silicon-based chargers. Thanks to GaN, portable chargers are getting smaller without sacrificing power.
You can now find powerful chargers that are the size of your average phone charger but can juice up multiple devices at once.

Quick Summary:
Portable chargers, or power banks, are rechargeable batteries designed to store energy for charging USB devices on the go.
Safety concerns arise from overheating, cheap knockoffs, or damaged units, but risks are low with proper quality chargers.
Proper care, like avoiding overcharging and using reputable brands, ensures safe and reliable performance.
Understanding Portable Charger Overheating: The Basics
The basics of portable chargers overheating is that their internal temperature exceeds safe limits and starts to get overly hot causing sometimes causing a fire.
This is very often due to fast charging, high capacity, or external factors like heat exposure. Low-quality or older models and fast chargers are more prone to overheating due to reduced efficiency or lack of thermal protection.
What Does Overheating Mean?
Overheating occurs when a portable charger’s internal temperature exceeds its safe operating limits. This temperature varies depending on the device, but in general to function safely the temperature has to be between 32°F and 113°F (0°C to 45°C). Temperatures above this range can heavily degrade the internal components and increase safety risks.
Heat in a charger primarily comes from the battery. As energy is stored or discharged, a small amount of heat is generated.
Normally, this heat dissipates harmlessly. But in certain conditions—like extended use or exposure to direct sunlight—can prevent the charger from cooling, which leads to overheating.
Why Do Portable Chargers Heat Up?
Heat is a natural by-product of energy transfer. When charging your device, the power bank converts stored energy into a usable form, a process that inherently generates warmth. So there’s always going to be some heat generated when using a portable charger. However, there are several factors that can amplify this heat:
Charging Speed: Fast-charging models generate more heat than standard chargers.
Capacity: High-capacity chargers store more energy, which can increase heat output.
External Conditions: Hot weather or enclosed spaces reduce a charger’s ability to cool itself.

Types of Chargers Prone to Overheating
While overheating can affect any charger, there are certain types that are more at risk than others.
Cheaper models often lack thermal protection, making them more susceptible to overheating.
Older Chargers
Over time, the battery’s efficiency decreases, which can lead to excessive heat buildup.
Fast-Charging Models
Fast-charging generates significant heat, especially during prolonged use.
Warning Signs of Portable Charger Overheating
Warning signs of portable charger overheating include excessive heat, unusual odors, physical deformation like bulging, poor performance, and audible sounds such as hissing or popping. These symptoms indicate potential internal damage or malfunction and should never be ignored.
Spotting these warning signs early can prevent damage and ensure your safety. So here’s everything you need to know about them:
1. Excessive Heat
A portable charger should feel warm during use, but it should never become uncomfortably hot to touch. If it does, stop using it immediately. Then get it checked out or just safely dispose of it at a local e-waste recycle center.
2. Unusual Odors
A burning or chemical smell is a major warning sign. It often indicates internal damage to the battery or other components. This is no joke, if this happens don’t ever try and touch it. The smell can indicate chemicals which could burn through your skin. Instead use gloves if you need to touch it and get rid of it as soon as possible.
3. Physical Deformation
Warped or discolored exteriors suggest the charger has been exposed to excessive heat. Bulging or swelling is particularly concerning, as it may indicate an impending failure.
Here’s everything you should be looking out for:

Power banks are quickly becoming as essential as your phone. With all our tech, we’re constantly charging—whether it’s for school, work, or play. A dead phone when you need it most? A total nightmare.
But with so many options out there, choosing the right 10,000 mAh power bank can be tough.
As a 15-year-old blogger from the Netherlands, I’ve spent over a year diving into tech and figuring out what works best for my needs. I know the frustration of a dying phone when you need it most. Which is why I’m breaking down why a 10,000 mAh power bank could be a solid choice for many.
Quick Summary:
A 10,000 mAh power bank provides a balanced mix of portability and power, ideal for everyday use and short trips.
It can typically charge most smartphones 2-3 times, making it perfect for daily commuters, students, and casual users.
While great for quick recharges, it may not be enough for heavy tech users or long outdoor trips. Where higher-capacity power banks would be better.
Before we discuss if a 10,000 mAh power bank is good, let’s first break down what mAh really means.
(I thought this image would kind off showcase capacity)
A power bank’s capacity is measured in milliampere-hours (mAh). This indicates how much power it can store, which translates to how many times it can charge your device.
The higher the mAh, the more energy it holds, which is why some power banks look like little bricks—more capacity equals more power.
Average Smartphone Batteries
To put things in perspective, most smartphones have battery capacities between 3,000 and 5,000 mAh.
For example, these are the battery capacities of the latest iPhone and Samsung
iPhone 15 Pro Max: 4,441 mAh
Samsung Galaxy S23 Ultra: 5,000 mAh
This means that a 10,000 mAh power bank can recharge your phone at least two to three times. Of course depending on your device.

Portability is another major factor. A power bank needs to be lightweight and easy to carry, slipping into your bag, backpack, or even your pocket. However, the more capacity it has, the bulkier it can get.
When traveling with multiple devices you will find a power bank with several USB ports extremely useful. However, keep in mind that charging multiple devices at once can slow the process down a ton. This is of course because the total output is divided between all these devices.
Portable Chargers: The Bigger, Broader Category
Power banks are by far the most common type of portable charger. However, portable chargers include a much broader range of devices like: car chargers or solar chargers.
So here’s a breakdown of the various portable chargers on the market in 2024:
Solar Chargers: If you’re spending time outdoors, hiking, or camping, a solar charger might be the ideal solution for you. These devices harness the great power of the sun to recharge your devices. Of course, they require sunny conditions, so don’t expect them to work well in cloudy or shaded environments. But on a bright day, you could be charging your devices completely off the grid.
Battery Cases: Designed specifically for smartphones, battery cases serve a dual purpose. They protect your phone while adding extra power. These cases are convenient, as you don’t have to carry around an extra charger all the time. This case makes sure your phone is constantly charging whenever it’s in it. However, they do add quite some bulk to your phone, so you may find them less comfortable to hold.
Wireless Charging Pads: Wireless charging is becoming increasingly more popular, and wireless charging pads are a growing part of the portable charger market. All you have to do is place your device on the pad, and it starts charging automatically, almost like magic. The catch here is that it’s usually slower than wired charging. However, if you’re okay with that and want to stop using a cable every single time, this is a convenient option.
Car Chargers: If you’re frequently on the road, a car charger is essential. These plug into your vehicle’s power outlet (cigarette lighter or 12V socket) and allow you to charge your devices while driving. It’s a great way to make sure you never run out of battery, especially on long road trips.
Portable chargers are about more than just recharging your phone. They give you options depending on where you are and what you need.
Key Features and Specs: What to Look For
A power bank is a rechargeable battery designed to charge devices on the go, often via USB. This makes it the classic portable charger because they’re compact, versatile, and reliable for charging devices anywhere.
However, portable chargers are a broader category that includes power banks, solar chargers, car chargers, and more. Each being tailored to specific charging scenarios.
Capacity (mAh): As mentioned, power banks’ capacities are crucial in determining how much charge they hold. A 10,000mAh power bank can charge your phone about twice, while a 20,000mAh or higher model can handle multiple devices. However, higher capacity means a larger, heavier charger which makes it a bit less convenient.
Charging Speed: Fast charging is a major consideration for anyone in a rush. Look for power banks and portable chargers that support Quick Charge 3.0 or Power Delivery (PD) technology. These charging methods significantly speed up the charging process for compatible devices, so that you’re not waiting around forever.
Port Variety and Compatibility: Not all chargers have the same ports. Some have USB-A ports, others have USB-C, and some even include a mix of both. Make sure the charger you pick has the correct port for your devices. If you’re an Apple user, you might prioritize USB-C and Lightning ports, while Android users might prefer USB-A or USB-C.
Portability vs. Power: If you’re looking for a charger to keep in your backpack for just-in-case moments, a small, portable power bank is ideal. Its moderate capacity will be a trade-off for this smaller size. However, if you’re heading out on a long trip, consider a larger charger with higher mAh to ensure your devices stay powered throughout the day or weekend.
How to Choose the Best Power Bank or Portable Charger for You
To choose the best portable charger, I would mainly focus on battery capacity, charging speed, and portability.
Ensure that it’s compatible with your device and consider extra features like multiple ports or fast-charging support.
So here’s a quick & simple checklist to help you decide between a power bank and other portable charging options:
If You Need to Charge Multiple Devices: If you’re traveling with more than one device, consider a high-capacity power bank or a multi-port charger. Larger mAh options (15,000mAh or above) have the added bonus of charging multiple devices at once.
For Outdoor Adventures: If you’re going off the grid, you could consider a solar-powered charger. It’s the best backup when you don’t want to rely on outlets. They’re especially useful for hikers, campers, or anyone spending extended time outdoors.
For Daily Use and Quick Boosts: If you’re just looking for a quick power-up during your daily activities, a compact power bank or battery case may suit your needs. These smaller options are easy to carry and provide just enough power for your phone or tablet.
For Convenience: If you don’t want to deal with tangled cords, a wireless charger is the way to go. Just drop your device on the charging pad, and you’re good to go. These are perfect for home or office use.
The Future of Portable Charging Technology
As technology progresses, the landscape of portable chargers and power banks is evolving equally as fast. With one of the main developments being faster charging speeds.
As smartphones, tablets, and laptops require more power to run efficiently, manufacturers are focusing on making charging faster. I expect portable chargers of the future to charge our devices in a fraction of the time that they do now.

Have you ever plugged in your laptop, only to wonder why it’s not charging properly?
Knowing the right wattage isn’t just tech trivia—it’s essential for keeping your laptop running smoothly. Using the wrong charger can lead to overheating, reduced battery life, and sometimes even permanent damage.
In this guide, we’ll find out your laptop charging wattage, helping you pick the right charger, troubleshoot common problems, and avoid costly mistakes. Say goodbye to guesswork and hello to a perfectly powered laptop. Let’s dive in.
Quick Summary:
To charge your laptop safely, match the charger’s wattage, voltage, and connector type with your laptop’s specifications.
Ultraportable laptops usually need 30-65W, while gaming laptops require up to 180W. Using a charger with higher wattage is safe but won’t speed up charging.
Modern GaN chargers are compact and efficient. Use manufacturer guides or system settings to confirm power needs and ensure compatibility.
Before you dive into the world of laptop charging, let’s break down some of the basic terms you’ll encounter. We’ll start with the differences between watts, volts, and amps.
Watts vs Volts vs Amps: What’s the Deal?
When it comes to charging, watts (W), volts (V), and amps (A) are the big three. These all explain how electricity flows and powers our laptop. They might sound a little technical, so let’s simplify it.
Watts ( W) represent the total power a charger can provide. It’s basically the amount of energy that your laptop needs to work and charge at the same time.
Volts (V) are the amount of electrical pressure being pushed through the charging cable to your laptop.
Amps (A) measure the flow of electrical current, essentially how much electricity is flowing.
In simple terms: watts are a combination of volts and amps. A charger with higher wattage can charge your laptop faster or supply more power to it.

As a general ballpark, laptop chargers should typically range from 30–240 watts, with voltages around 18–20V and amperage between 1.5–12A, of course depending on the device. Low-power laptops need less (30–45W, 1.5–2.5A), while high-performance laptops demand more (100–240W, 6–12A).
How to Read Your Laptop’s Power Brick Specifications
If you look at your laptop’s power brick (the big, boxy part of the charger), you’ll find these numbers on the label. It might seem like a jumble of letters and numbers at first. However, this is where you can find all the info you need.
(Image credit: throughtheeyesofateenager.com)
Typically, you’ll see something like “19V” and “4.74A” which means the charger supplies 19 volts at 4.74 amps. Multiply those together, and you get the total wattage. In this case, it’s about 90 watts. Or for the example in the image above it says: ”19.5V” and ”2.31A”. Multiply those together, and you get about 45 watts.
Common Charging Connector Types
You might also notice different types of connectors when choosing a charger. The most common ones are:
USB-C: A newer, more universal option. It’s smaller, faster, and reversible (no more fumbling to plug it in the right way).
Barrel Plug: The classic round connector that’s been around for years, still used in many laptops.
Understanding what type of connector your laptop uses is just as important as knowing its power requirements. It’s normally pretty easy to see if your laptop uses a barrel- or USB-C plug. However, one thing to keep in mind is that the barrel plug’s may very significantly in size. I’ve had it many times when I tried to charge my laptop, just to realize it wont go in because the cable was for a other laptop and therefor to big or small.
How to Find Your Laptop’s Exact Power Requirements
Your laptop will need about 65-100W, however this highly depends on the brand and model, so it might be a lot more or less.
To find your laptop’s exact power requirements you can, check the original charger specifications, look up the manufacturer documentation or use system settings if you’re using a mac. These all might sound complicated but don’t worry—their super easy!
1. Checking the Original Charger Specifications
The easiest way to determine your laptop’s power requirements is by checking the charger that came with it. On the charger itself, you’ll find the voltage and amperage rating. These numbers tell you exactly what your laptop needs.
As I previously also explained, if you do the voltage times the amps you’ll find the wattage. If you don’t know what any of these mean, go back to the previous section about basic laptop charging terminology where I explain it in detail.
2. Looking Up Manufacturer Documentation
Don’t have your original charger? No problem! Visit the manufacturer’s website and look up your laptop model. There, you’ll usually find the exact power specifications under “technical details” or “specifications.”
As shown in the example above, this laptop(Asus UX8402ZA) has a 20V, 7.5 Amps and 150W power supply. This is a pretty high-end gaming laptop so your laptop will probably have quite a bit less power.
3. Using System Settings to Verify Power Needs
If you want a quick check, your laptop may also list power information in its settings. As far as I know this is only possible on mac and not on windows. So for Mac users, you can go to the “System Report” and find “Power” under hardware.
Windows users will have to stick to the other methods to find specific charging capabilities for their laptops.
4. Common Wattage Ranges for Different Laptop Types
Different types of laptops have different power needs. This highly depends on the type of laptop, the brand and the model of the laptop. However, as a general ballpark, this is a idea of what you might encounter:
Ultraportable laptops: 30-65W
Standard consumer laptops: 65-90W
Gaming laptops: 130-180W
Professional workstations: 150-230W
And for MacBooks, you can expect to see varying requirements depending on the model. For instance, the MacBook Air needs around 30W, while the MacBook Pro might require up to 96W or more. You should be able to find this on the official Apple website.
Typical Laptop Power Requirements by Category
Understanding your laptop’s category will help you know what kind of charger you need. So here are 5 general power requirements for each category:
1. Ultraportable Laptops (30-65W)
If you’re using an ultrabook or a thin laptop designed for portability, like a chromebook for example. Then it usually requires a lot less power. These laptops focus on energy efficiency and longer battery life, so they tend to have lower wattage requirements.
2. Standard Consumer Laptops (65-90W)
Most everyday laptops, the ones you use for school, work, or streaming, fall into this category. They have mid-range power needs, usually requiring around 65W to 90W to work and charge properly.
3. Gaming Laptops (130-180W)
Gaming laptops are generally power-hungry beasts. They need higher wattages to power their powerful CPUs and GPUs. Expect to see wattage ratings in the range of 130W to 180W, and possibly even more depending on the specific model and brand.
4. Professional Workstations (150-230W)
If you’re running design software or doing other intensive tasks, you’re probably using a professional-grade laptop. These devices require a lot of juice to keep up with demanding programs. They usually need between 150W and 230W.
5. MacBook Power Requirements by Model
MacBook power requirements can vary, with the Air requiring just 30W. However, once you get to the Pro models, you will need 61W or 96W depending on the screen size.
Can You Use a Higher or Lower Wattage Charger?
Here’s the thing: it’s not just about grabbing any charger. The wattage matters. So, let’s explore what happens when you use the wrong one.
Understanding Minimum Power Requirements
If your charger has too low of a wattage, your laptop might not charge at all or could charge extremely slowly. This happens because the charger can’t supply enough power for both running the laptop and charging the battery. So you essentially break even.

Risks of Using an Underpowered Charger
Using an underpowered charger means your battery will take forever to charge—or it might not charge at all. Worse, it can stress the battery, decreasing its lifespan over time. You could end up in a situation where your laptop dies quicker than it should. Just because you’ve been using the wrong charger. It is possible, but I wouldn’t recommend it.
Safety of Using Higher Wattage Chargers
Now, what about using a higher wattage charger? Generally, this is safe. A charger that delivers more power than your laptop needs will only supply the required amount. However, it may generate more heat, which could affect battery life in the long run. I wouldn’t recommend you do this all the time, but if there’s no other option then it’s okay to do it every now again.
Charging Time Differences with Various Wattages
Here’s the good news: a charger with higher wattage could charge your laptop faster (if your laptop supports it). But be aware: the increase in charging speed might not be drastic. Especially if your laptop is designed for lower wattage.
(Image credit: throughtheeyesofateenager.com)
Impact on Battery Longevity
Repeated use of high-wattage chargers might affect your laptop’s battery health over time. So, you can use a higher or lower wattage occasionally, however it’s best to use the recommended wattage for regular charging.
Common Laptop Charging Problems and Solutions
Even with the right charger, things can still go wrong. Here are some common issues and how to fix them.
1. Slow Charging Troubleshooting
If your laptop charges slowly, check your charger and cable. A low-power charger or damaged cable can slow things down. Also, make sure your laptop is plugged into a wall outlet and not a USB port on a computer, which provides a lot less power.
2. Battery Not Charging at Full Speed
If the battery isn’t charging at its normal speed, check if there’s an issue with the charging port or if the laptop is overheating. Some laptops use slow charging to avoid heat damage.
3. Charger Compatibility Issues
Not all chargers work with every laptop. If you’re using a third-party charger, check for compatibility issues. Look up your laptop’s charging specs to ensure the charger matches.
4. Temperature-Related Charging Problems
Extreme temperatures can cause loads of problems like:
Battery Damage: High temperatures can cause your laptop battery to overheat, leading to reduced capacity, swelling, or even permanent damage. Cold temperatures can slow the charging process and reduce the battery’s overall efficiency.
Performance Issues: Overheating during charging may trigger thermal throttling, slowing down your laptop to prevent damage. Similarly, cold conditions can impact internal components, making the laptop sluggish.
Safety Risks: Prolonged exposure to heat may increase the risk of fires or explosions if the battery becomes unstable.
Shortened Lifespan: Both high and low temperatures accelerate wear and tear on your battery, reducing its lifespan over time.
How Many Watts Do I Need to Charge My Laptop – Conclusion
