Anker Prime 100W GaN Charger Review: One Brick, Three Devices, Done
The charger that lets you leave the rest of the bricks at home.
100W across four ports in something smaller than a soap. It charges a laptop and two phones at once without complaint. The only thing it’s missing is a longer cable in the box.

Quick verdict
Who it's for
Travelers and desk minimalists who want one brick for everything.
The good
- 100W real output, not marketing peak
- Four ports (2 USB-C, 2 USB-A) — laptop + phone + buds + watch
- GaN runs cool even under full load
The bad
- No cable included
- 100W is shared — a hungry laptop pulls it down with others attached
- Pricey for a charger until you count the bricks it replaces
I used to travel with a laptop charger, a phone charger, and a watch charger. Now I travel with one. That’s the whole review, but let me justify it.
Real 100W
Anker’s wattage numbers have historically been honest, and this one is. With a single USB-C device pulling hard, I measured 97W on a Mac — close enough to the claim. Split across a laptop and two phones, the laptop got 65W and the phones shared the rest. Nothing complained.
The thing that matters: it didn’t throttle off heat. Older GaN bricks at full load turn into hand-warmers and drop output. This one stayed cool and consistent over a 40-minute top-up.
Ports and practicality
Two USB-C, two USB-A. That covers a modern laptop, a phone, earbuds, and a watch with a legacy cable. The foldable prongs mean it doesn’t jab everything else in your bag.
The miss: no cable in the box. For the price, a 6-foot USB-C cable wouldn’t have killed them.
Worth it?
It’s expensive for a charger. It’s cheap for replacing three chargers. If you move around with a laptop and a phone, this is the one brick to own.
