Gallium nitride (GaN) transistors switch faster and waste less energy as heat than silicon, which is why a 65W GaN brick is half the size of the laptop charger it replaces. These eight picks come from our fleet's USB-C charging research — match the wattage to your hungriest device and everything smaller takes care of itself.

Anker 737 GaNPrime (120W)

- 120W total output
- Smart power splitting
- Charges two laptops at once (slower)
UGREEN Nexode 100W

- Full 100W single-port
- Compact for its class
- Trusted safety certifications
Anker 511 Nano 3 (30W)

- Full-speed phone fast charging

How to choose
Wattage first: phones fast-charge happily at 30W, tablets and ultrabooks want 65W, and gaming laptops need 100W or more. Ports second: a two-port 65W charger splits its output when both are busy, so check the split table if you charge a laptop and phone together. Finally, fold-flat pins matter more than you'd think for travel — a charger that sits flush in a bag pocket gets carried; one that snags gets left behind.

Frequently asked questions
Is a GaN charger safe for my phone?
Yes. The phone negotiates the power it wants over USB-C PD; a 120W charger still feeds a phone only what it asks for. GaN just makes the charger smaller and cooler.
How many watts does my laptop need?
Most ultrabooks charge fully at 65W under load. Thin-and-light gaming laptops and 16-inch workstations need 100W+; check your current brick's rating and match it.
Do I need special cables for fast charging?
For anything over 60W, yes — a USB-C cable rated for 100W/240W. A bargain-bin cable can silently cap you at 60W.
