Abstract

A plug-and-socket arrangement connects a portable appliance to a mains-powered battery charger/power supply. To avoid unwanted power consumption while the appliance is not connected, the plug-and-socket arrangement, when unplugged so that the appliance can be made portable, disconnects the mains power from the battery charger/power supply.
