GaN & Wattage
What is a GaN charger and how is it better than a traditional charger?
A GaN charger uses gallium nitride power devices instead of traditional silicon, enabling higher switching frequencies, higher efficiency and much smaller size at the same power level. That means more power in a travel-friendly form factor with better thermal behaviour when designed correctly.
