Best GaN chargers 2023

The best chargers to buy today for laptops, Android phones, and everything in between these days are GaN chargers, short for Gallium nitride. Semiconductors made with Gallium nitride, like the Anker 313 Ace, can be smaller than traditional silicon chips, and smaller chips make smaller, lighter, and ultimately better chargers. The tech has been around for a couple of years now, but this is still a relatively small field. These are the best GaN chargers with Power Delivery charging you can buy today.

What GaN actually is and what it does in your charger

GaN stands for Gallium Nitride, an alternative to the traditional silicon that has dominated electronics for the last few decades. Gallium nitride has some advantages — a wider band gap means it's easier for energy to pass through it, and it has higher limits for the temperatures and power levels it can handle — that makes it almost tailor-made for higher-capacity tech like Power Delivery chargers for today's best Android phones.

In short, semiconductors and chargers made with gallium nitride are smaller and more efficient, which in turn can help them avoid heating up as much as traditional silicon-based chargers.

However, since the goal of most gallium nitride chargers is to be as small as possible, some GaN chargers still get uncomfortably warm when used for long periods of time because they don't have as much room for heat dissipation. You're not going to be able to bake a cookie on a GaN charger the way you can on a MacBook brick during an all-night editing session, but they'll still get a little warm depending on how hard you work them.

What makes the Anker 313 Ace the best GaN charger on the market

In an age where you can charge quite literally all of your tech via one protocol — from your laptop to your phone to all the power banks and headphones in between — one good Power Delivery charger with PPS can replace a dozen chargers. So if you can get away with a single-port charger — or you need a charger for your purse or backpack — the Anker 313 Ace is the perfect choice.

45W is the top speed for charging the best Chromebooks and many USB-C laptops, and it will charge almost all tablets at top speed, too! It can even deliver 45W charging on phones like the Galaxy S23 Ultra thanks to its support for Super Fast Charge 2.0. Just make sure you also grab one of the best USB-C cables with 5A support to use with it.

If you need to charge two devices at once — think of two students with Chromebooks for homework — the Spigen 120W ArcDock is a great pick. Not only does it have enough power for two power-efficient laptops at once, but it also has the ports to top up all of your essential devices once homework is done.
