Plug Loads & Vampire Loads
A plug load consists of one or more devices plugged into an outlet or power strip. Vampire loads (also known as phantom plug loads) secretly drain electricity when an electronic device is turned off, but still plugged into an outlet.
A phone charger plugged into a wall without a phone connected to it still consumes a small, but continuous amount of electricity. Coffee makers, toasters, and printers also consume energy when plugged in, even when the devices themselves are turned off.
