Portable Charger Technologies: A Complete Guide to Fast Charging in 2024

What’s the Deal with Portable Chargers Anyway?

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.
• Universal Compatibility: Works with a wide range of gadgets, reducing the need for multiple cables.
• High-Speed Data Transfer: Supports much faster data rates compared to USB-A, perfect for large file transfers.
• Compact and Sleek: Its small design fits seamlessly into modern devices without taking up too much space.

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.

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:

It’s great for Samsung Galaxy devices and other compatible gadgets. The advantage of Samsung’s system is that it adjusts the charging power based on your device’s needs. Making it super efficient without overloading your battery.

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.
