What Is a GaN Charger, and Why Will You Want One?

Gallium Nitride (GaN) chargers were everywhere at CES 2020. This modern alternative to silicon means smaller, more efficient chargers and power bricks are on the way. Here’s how it works.
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.
