Same awesome design and features with even more power.

Increasingly I find the devices I own are all USB-C meaning I am moving away from my older USB-A devices. The beauty of the UGREEN X GaN is that it includes 3 USB-C and 1 USB-A. If I really need more A ports, I can always use a USB-C to USB-A adaptor.

Overall, the charger is not only powerful with a maximum output of 100W but also has a nice sleek design with dimensions of just 6.9cm x 6.9cm x 3.3cm.

I have been using the UGREEN GaN X 100W for some time now, and it has definitely made my life easier, thanks to its fast-charging capabilities and portable design.

Design and Build


Compact and Portable

As soon as I unpacked the UGREEN GaN X 100W charger, I was taken aback by its compact size. I didn’t expect a 100W charger to be this portable, especially considering the high power output it has. Measuring a mere 6.9cm x 6.9cm x 3.3cm, the GaN X is perfect for taking with me on trips without having to worry about carrying around a bulky charger.

I can easily slip it into my bag or even my pocket when I’m on the go.

Material and Durability

When it comes to material, UGREEN has given the GaN X charger an impressive build quality. Its shell is made of fire rating PC/UL94-V0 – a material that ensures enhanced durability and heat resistance. This feature gives me peace of mind, especially when I need to leave the charger plugged in for extended periods, knowing that it’s made from robust and secure material.

As I held the charger in my hand, I could feel the premium matte finish that gives the product an elegant and sleek look. And the glossy edges caught my eye, showing the attention to detail put forth in designing this gadget. This quality build definitely speaks to the charger’s potential long-term durability, too.

Wattage and Compatibility

With a maximum output of 100W, it has enough power to charge my MacBook Pro and iPad Pro at the same time. At the same time, its USB-A port provides a solid 22.5W of output for charging other devices. I especially like this feature because I can charge an array of gadgets, from my iPhone 13 to my Nintendo Switch, all with just one charger.

Efficient Charging Technology

UGREEN Gan X 100w Fast Charger

My favorite part about the UGREEN GaN X 100W Fast Charger has to be its GaN (Gallium Nitride) technology. Chances are you’ve heard of this advancement in the world of chargers, and it truly lives up to its reputation. GaN technology allows for smaller and more efficient chargers, providing a fast and safe charging experience.

In my time using this charger, I’ve consistently noticed shorter charging times for my devices, thanks to its efficient Power Delivery and proprietary charging technology. The charger itself remains cool to the touch, even when powering up multiple devices, which is a testament to its advanced design.

Protection and Safety Features

The charger has a low static power consumption of ≤0.3W, which means it doesn’t use much energy when not actively charging a device. This is not only good for the environment, but it also helps keep your electricity bill in check.

Input overvoltage protection is another essential safety feature included in the UGREEN GaN X charger. This means that if the input voltage is too high, the charger will automatically shut off, preventing any damage to itself or the devices connected to it.

I like that it fits in my bag easily – it’s not tiny but it’s compact for something that packs this much power.

Alternatives to Consider

While the UGREEN GaN X 100W is a fantastic charger, it’s worthwhile to explore other options that might better suit your needs.


If your devices don’t require the full 100W charging capacity, the UGREEN GaN X 65W is a more affordable and compact option. It offers the same benefits, such as GaN technology and multiple charging ports, but at a lower maximum output.
