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 Nano II 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.

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 Nano II 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 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 — it's hard to deny the appeal of the ridiculously tiny Anker Nano II 45W. This charger is available in 30W and 65W models, but the 45W is the Goldilocks of the bunch in both size and price. 45W is top speed for charging the best Chromebooks and many USB-C laptops, and it will charge almost all tablets and phones at top speed, too!

The RAVPower 90W charger is a great model for those that need to charge two devices at once, such as charging a laptop and a phone overnight in your hotel room. It's also a great investment for households where you need to charge multiple Chromebooks at once, such as the family charging station for all the kiddos' laptops.
