What is GaN charging, and do you actually need it?

Smaller, cooler, faster. Worth the upgrade for anyone travelling with more than one device.

## What it is Gallium Nitride (GaN) transistors replace silicon in the charger. Result: ~40% smaller, ~30% cooler, ~50% more efficient at the same wattage. ## Who needs it If you own 2+ USB-C devices (phone + laptop + earbuds), one GaN brick replaces 3 regular chargers.
