For a long time, my work desk has been a mess of wires. I usually had two chargers plugged in: one for my MacBook Air and another for my iPhone 17 Pro Max. None of this felt unusual at first, until I realised how much space they were taking up and how often I was unplugging one thing just to charge another. That’s where the Asus 100W USB-C GaN charger slowly slipped into my routine. There wasn’t a dramatic first impression as such, but this tiny gadget won me over in no time. Within a few days, I had removed two chargers from the desk and didn’t feel the need to put them back. That’s usually the best sign that something is actually useful, not just impressive on paper.

What makes this Asus GaN charger work so well is how comfortably it fits into daily use. It’s compact enough to sit behind my desk without sticking out or blocking neighbouring sockets, which is still an issue with many high-wattage chargers. GaN technology plays a role here, but what matters more is that it doesn’t feel like a compromise. Despite the small size, it handles my MacBook Air and iPhone together without any drama. The charger stays warm at most, never alarmingly hot, even during long workdays when everything is plugged in for hours.
The included 1.5-metre USB-C to USB-C cable deserves a special mention. On a work desk, cable length matters more than people admit. The 1.5-metre length hits the sweet spot, and this extra reach lets me keep the charger plugged in under the desk while comfortably using my laptop on the surface. Also, I’m not constantly tugging at cables or repositioning the charger, and that small convenience adds up over time. That said, I did end up using Apple’s braided cable for the second USB-C port.
Speaking of which, port selection is another area where the Asus GaN charger feels thoughtfully designed. With two USB-C ports and one USB-A port, it covers both modern and slightly older devices. My MacBook Air lives on the primary USB-C port, while my iPhone usually takes the second USB-C port. The USB-A port can come in handy for accessories, and while it’s limited to lower output, it’s still useful for things that don’t need fast charging. Personally, none of my devices require me to rely on USB-A charging, so I never really felt the need for it.
Power distribution feels sensible, too. The laptop gets priority, and even when all three ports are in use, I’ve never felt like my MacBook was charging unusually slowly.
That said, like most things, the Asus GaN charger isn’t perfect. If you rely heavily on USB-A devices, having only one such port may feel limiting. The white finish also looks clean and minimal, but it does tend to show marks over time, especially if you travel with it often. These aren’t deal-breakers, but they’re worth knowing before you buy.
Where this charger really shines is in its versatility. It works just as well at home as it does at the office, and it’s easy to imagine carrying it while travelling instead of packing multiple adapters. You’ll still need to carry extra cables, of course, but that’s far better than carrying bulky charging bricks. With support for a wide voltage range, it’s also one less thing to worry about when plugging in abroad.
Summing it up, in daily use, the Asus 100W USB-C GaN charger doesn’t really try to impress you. It simply removes friction. Fewer chargers, less clutter, and one reliable brick that powers everything I actually use. Once you experience that kind of simplicity, it’s surprisingly hard to go back.
