GaN charger
A charger built with gallium nitride instead of silicon, which lets it be smaller for the same power.
On a multi-port GaN charger the rated wattage is the total across all ports, so a laptop and a phone share it when both are plugged in. Check how the maker splits power between ports before it becomes your only charger.
