The Advantages of a Gallium Nitride Charger:
GaN chargers are physically smaller than current chargers. This is because gallium nitride chargers don’t require as many components as silicon chargers. The material is able to conduct far higher voltages over time than silicon.
GaN chargers are not only more efficient at transferring current, but this also means less energy is lost to heat. So, more energy goes to whatever you’re trying to charge. When components are more efficient at passing energy to your devices, you generally require less of them.
