Good to know
Power supply vs. charger
power supply
function
Converts mains electricity (AC) from the wall socket into suitable direct current (DC) for a device.
Application
Power supply for devices directly during operation, not necessarily for charging batteries.
Battery-powered devices are supplied with a power adapter only if a charge controller is integrated into the device.
charger
function
Charges battery-powered devices, regulating the current to ensure safe and full battery charging. Features an automatic shut-off function and charge level indicator (LED light).
Application
Batteries in smartphones, laptops, rechargeable blood pressure monitors, etc.
