Other forms: chargers
A charger is the cable and plug that refill a device's battery. Phone charger, forgot my charger, a fast charger.
Fast chargers push more power and are limited by what the device will accept, not by the plug alone. The USB-C connector is now required on new phones sold in the EU, which was a deliberate move to reduce the number of chargers thrown away. Note that a charger is also a warhorse, and a large flat serving plate — two older senses of the same word.
