While electronics have been including GaN, or gallium nitrate, as a conductor for decades, it's increasingly becoming a popular swap for traditional silicon chargers due to the material's power efficiency and compact size.

If you're looking for a smaller, faster, and more compact charger to power anything from your laptop to smartphone, it might be worth upgrading to a GaN charger.

Over the past year, many manufacturers have put out GaN charging accessories to effectively power, with Ugreen and Anker as market leaders. That said, our hands-on testing showed Ugreen's GaN charging lives up to the hype, making the Ugreen 100W Nexode GaN Charger ZDNET's choice for the best GaN charger overall due to fast performance, vast connectivity options, and easy portability. Read on for more pros and cons of this charger and to compare other top GaN chargers.

In fact, it takes less than 30 minutes to charge your M2 Macbook Air to 55% percent.

Anker brings its reliable performance to its Nano II 45W Charger, packing 45 watts of power in a tiny package that is 34% smaller than its original 45-watt charger. It is easily foldable for simple storage when space is scarce.

With USB-C connectivity, it uses GaN II technology to offer 20% more in operating frequencies without sacrificing its petite size. There is just one port, so it is not the charger you want when you have to charge multiple devices, but compatibility is still fantastic. It works with devices like your MacBook Pro 13, Galaxy S22 Ultra, and iPhone 13. It even works with your Apple Watch, Nintendo Switch, or your favorite pair of earbuds.

The Satechi 100W Charger is also one of ZDNEt's picks for the best USB-C laptop chargers, using GaN technology for faster charging in a small, portable package. In this model, GaN replaces the silicon semiconductors of previous versions for a noticeable improvement in speed and size.

With 100 watts of power, it is more capable than some of the smaller chargers on our list. That makes it an appropriate fit for your more power-hungry devices, like your M2 MacBook Pro or M1 MacBook Air. With USB-C connectivity, it is no problem to use your newer devices with two USB-C ports to choose from. In total, there are three ports with an extra USB-A port available, as well.

Still, it remains portable, not taking up much space at all to get the job done.

If you need something small and compact, the Spigen ArcStation Pro Charger is the best portable GaN charging accessory you can buy. This model moves on from the previous Silicon Chipset and instead boasts a Navitas Gallium Nitride (GaN) Chipset that is powerful enough to allow for a smaller size.

It is a USB-C charger with GaN technology for faster charging when it comes to devices like your Galaxy S23 Ultra, Note 20, or iPad. It has no problem working with foldable phones; in fact, it comes with its own foldable plug to help cut down on space.

There is but one port with up to 45 watts of power for a single device. Still, you will find it is an excellent fit for both mobile phones and laptops, including the Samsung Z Fold 4, Note 20 Ultra, and Galaxy Tab S7 Plus.

Wotobeus 130W USB C GaN Multi-Port Charger specs: Type: Wall plug-in | Wattage: 130 watts | Output voltage: 240 volts | Total ports: 4 | Dimensions: 3.37 x 1.16 x 2.4 inches | Weight: 0.64 ounces

With 130 watts of power, this wall charger is the most powerful GaN charger on our list, offering some of the fastest charging you can get. It comes with both USB-C and USB-A options, so you can charge everything from your iPhone XR to your Samsung Galaxy Note 20 and even your MacBook Pro or Nintendo Switch. It has enough power that you can actually charge two separate laptops on this single charger, giving you super-fast charging in a fraction of the time.

Best of all, it is compatible with a series of fast-charging technologies like Qualcomm Quick Charge 4.0+ and Samsung Super Fast Charge 2.0 for a premium performance not typically seen in most GaN chargers.

The best GaN accessory is the UGREEN 100W Nexode GaN Charger, which includes the most ports on our list with a fantastic 100 watts of power. It is on the pricier end, but our team agrees after testing that the UGREEN brings the fastest, most accommodating charging of all devices.

To find the best GaN accessories, there are several factors to keep in mind.

Power rating: Each GaN accessory is rated for a certain amount of power, whether it is 45 watts or 130 watts. A fast-charging GaN accessory generally has more than 5 watts of power, which is the standard for chargers, according to Belkin. However, the higher the number of watts, the more power you will have and the faster your device will charge.

Ports: The number of a GaN accessory's ports will determine how many devices you can charge at a single time. Most GaN chargers have one port, but there are some, like the UGREEN 100W Nexode GaN Charger, that have up to 4 ports or more.

Compatibility: Before you buy a GaN accessory, be sure to check that it is compatible with your devices. From your mobile phone to your laptop, there may be specific charging requirements that need to be met in order for you to benefit from fast charging technology.

Price: The cost of GaN accessories can range in cost significantly based on things like the number of ports and the power wattage. Pricing can vary, but the best GaN accessories range in cost from $30 to $90, making it easy to find the best GaN accessory under $100 for your needs.

A gallium nitride accessory, or GaN accessory, is a type of charger that uses semiconductor material instead of silicon to provide faster charging. This enables it to work at higher temperatures and voltages, thus putting out more power than your standard charger.

There are many brands that make GaN accessories, but not all of them may provide the most consistent or advanced performance. I found that the best GaN accessories come from popular brands like Anker, Spigen, and UGREEN. Satechi and Wotobeus also make an appearance.

There are many ways to buy GaN accessories. At ZDNET, we find that Amazon offers some of the most affordable pricing, but we also compare pricing from other trusted retailers like Best Buy, Walmart, and B&H Photo & Video. You can also buy a GaN accessory directly from the manufacturer, although you may face higher pricing and longer shipping times.
