Without a connected device, will a cable draw power from Anker wall chargers?
The Lightning cable contains an active chip that causes it to be detected by power sources even when there's no device on the other end of the cable. As a result, the lightning cable will draw power from a wall charger even with no actual device plugged into the other end, while other kinds of cable such as the USB-C cable won't.
Therefore, when you want to charge a high-wattage device using our multiport charger such as GaNPrime chargers, it’s suggested to unplug the lightning cable in other charging ports for the best charging performance.
