Which devices it works with

Rule: USB-C power (chargers and USB-C power banks) — Works with anything that charges over USB-C. Lightning devices need a USB-C to Lightning cable and Apple Watch uses its own USB-C charging cable, so those show as Works with adapter. Desktop Macs, Apple TV and most HomePods run from the mains. If Apple states a minimum wattage for a device and the charger is below it, it shows as Not compatible.
