BUYING GUIDE
Why GaN Chargers Matter
GaN (Gallium Nitride) transistors are more efficient than silicon, producing less heat and enabling smaller charger designs. A 100W GaN charger is typically 40-50% smaller than an equivalent silicon charger.

Power Splitting Between Ports
When multiple devices are plugged in, total wattage is split. A 100W charger with two devices might deliver 65W to your laptop and 35W to your phone. Single-port use delivers the full 100W.
