The best GaN chargers is something everyone with a phone, tablet or laptop should know about. Because, quite simply, they'll power up these devices more quickly than a traditional type of charger.
This new generation of chargers use gallium nitride rather than silicon, which is better at conducting electricity. And this makes them smaller, more energy-efficient, cooler, and able to charge more quickly than silicon chargers.
This means you'll save space, save money on electricity bills and won't have to wait around so long for your phone, tablet, camera, or laptop to be at 100%. So really, why would you buy any other type of charger?
Below we've brought together the best GaN chargers on the market today. Choosing between them is mainly about how what sort of devices you want to charge. A 45W charger is fine for a phone, but for a powerful laptop you'll need something more like 100-200W. Also, if you need to power up more than one device at once. some GaN chargers come with lots of ports. Alternatively, if you're looking for a different type of charger, see our guides to the best wireless chargers and the best solar chargers.

Best GaN charger overall
I am a big fan of the Anker Prime range of chargers and this one at 100W is probably the best of the lot for a size-power ratio. The Anker 100W is a compact and powerful charger that will free you from carrying around large bulky chargers, or even worse, chargers with separate power bricks. The charger also offers enough power out of one port to easily keep the best (non-gaming) laptops running at max juice all day, and with three ports to charge all your devices quickly when needed.
The size Anker has shrunk this charger to I think is amazing, it is so light and I can easily slip it into a pocket if needed. The Anker 100W has a sleek design and a durable build quality, although it does get quite hot when used to maximum capacity. It has two USB-C ports that support Power Delivery (PD) up to 100W, which means it can charge most laptops, tablets, and smartphones at their optimal speed. It also has one USB-A port for older or lower-power devices that still rely on that connection. The charger also has a smart chip that detects the connected devices and adjusts the output accordingly, ensuring safe and efficient charging for all your devices.
Whether you are traveling, working, or using it around the home, I think the Anker 100W is a great choice for anyone who needs a versatile and portable charger that can handle multiple devices at once.

Best GaN charger for phones
When it comes to choosing the best GaN chargers, there are a lot of factors to consider. However, the most important ones are price and power. If you’re looking for a charger that offers great value at the lower end of both of these, then the Anker Nano 3 (30W) power adapter is an excellent choice.
This tiny device is capable of charging a MacBook Air at full speed, an iPhone up to three times faster than with an original 5W charger, and the latest Samsung phones at full speed with Samsung Super Fast Charging. It’s a versatile charger that can handle all your charging needs.
However, there are some downsides to this charger. For one, there’s only one port, which means you can only charge one device at a time. Additionally, it’s not suitable for large laptops. So if you have a larger laptop that requires more power, you’ll need to look elsewhere.

Best desktop GaN charger
The Anker 250W GaN charger is a standout option for anyone looking to power multiple devices efficiently. While I initially thought the built-in display was just a novelty, it’s actually become an incredibly helpful feature. The screen lets me monitor charging speeds and track how much energy my devices are using. With energy costs on the rise, I’ve found it particularly useful for spotting unnecessary power drain and disconnecting devices that aren’t in use.
The charger’s 250W output is more than enough for most desk setups. It easily handled all my devices, from laptops and phones to earbuds, without any issues. I haven't come close to maxing out its capacity, so unless you have an unusually power-hungry setup, this charger will meet your needs. Its ability to charge multiple devices simultaneously without performance drops makes it a reliable, efficient choice for anyone looking to simplify their charging station.

Best powerful GaN wall charger
I tried out the Ugreen Nexode 140W 3-port charger and it worked wonders. I would go as far as saying it is the only charger you are going to need. It is powerful enough to support even the most power-hungry laptops and devices with 140W single port charging.
Even with all three ports in use, there is enough power to keep less power-intensive laptops running, alongside your phone and other devices. I pushed this charger as hard as I could with two laptops and a phone and it kept all three juiced up while running with no issues like power drop-outs or overheating.
The charger itself is well-designed and looks great. It is lightweight, but it is a little larger than some of the lower-powered devices on the market, so it will take up a little more room in a bag, or require a bit more space around your wall outlet. It also isn’t the cheapest charger on the market, but for the power and future-proofing, I think this is a great investment.

Best wall charger for power and ports
For the past week, the Belkin BoostCharge Pro has been my primary wall charger, and its performance has left me thoroughly impressed. With four ports capable of delivering a whopping 140W of power, it effortlessly charges even my most power-hungry laptops at maximum speed. The ability to charge multiple devices simultaneously without sacrificing charging efficiency is a definite plus.
What I find particularly useful is the inclusion of adapters for various countries. This feature not only makes the charger an ideal travel companion but also eliminates the need for separate adapters, saving me both money and the hassle of remembering to pack them!
However, there is a minor downside. The charger's size is quite substantial, which means it occupies a significant amount of space in my bag and around the socket. This can make it challenging to use in confined spaces. It's probably on the larger end of what I'd be comfortable carrying around.

Best GaN charger with MagSafe wireless
The Ugreen Nexode 100W GaN charger is a delightful addition to my meticulously arranged desktop setup, thanks to its 15W MagSafe feature that brings a touch of elegance when I place my iPhone on the MagSafe charger in landscape mode, it transforms into a beautiful desktop clock, merging functionality with style. In general, the charger’s design is visually appealing and enhances the overall look of my workspace.
The charger’s robust 100-watt output provides ample power to charge my MacBook or phone through its two USB-C ports or lower-powered devices through the single USB-A port, which makes the charger very versatile. However, the 100W single port rating does drop quite a bit when multiple ports (or the MagSafe pad) are in use at the same time.
The only feature I find missing is a second wireless charger beneath the top surface, which would have been ideal for charging my AirPods or Apple Watch, thereby increasing its versatility. Nevertheless, given the rarity of chargers that offer both wireless charging and a powerful desktop charger combination, this is one of the best desktop chargers I’ve used.

How to choose the best GaN charger
Firstly think about how many devices you want to power, and what power ratings your devices have.
If you want to power a lot of smaller devices, then you need to look for a charger with the highest number of ports. If this can be combined with a big maximum wattage from the charger then that will mean you can charge these many devices even faster. Phones, headphones, and wearables all charge at quite low rates compared to laptops, so can usually all be charged simultaneously at full speed.
If you have one of two big devices that are power hungry like a laptop then this means you might be better off with a powerful charger with just a few ports as the more you plug into the charger the more you dilute the total power until you get to the point where it is not able to power your most needy devices.
What's the difference between GaN and GaN2
GaN2 (or GAN II) is the latest generation of GaN charging technology - providing improvements in power transfer, heat dissipation, and charging speed over first-generation GaN devices.
What does GaN stand for?
GaN is short for Gallium Nitride. It's a natural mineral, that is an alternative semiconductor material to silicon. Gallium nitride allows manufacturers to make chargers that are smaller, faster, and more power efficient than the brick-like silicon chargers that we have grown up with.
How we choose the best GaN chargers
