Do Plugged In Chargers Use Electricity. According to my tests a genuine Apple iPhone charger uses in the region of 135W of power a month which equates to just over 15KW h a. A phantom load is any electronic device or appliance that consumes electricity when turned off but still.
A household with multiple wireless chargers left plugged in say a charger by the bed one in the living room and another in the office could waste the same amount of power in a day as it would take to fully charge a phone. In fact this is how it is designed to function. If the charger is not actually connected to the phone but is still plugged into the wall-socket then there will be a very small amount of power still drawn but most phone chargers these days have a very low phantom power draw that can usually be ignored.
Most drivers of plug-in electric vehicles PEVswhich include all-electric vehicles EVs and plug-in hybrid electric vehicles PHEVscharge their vehicles overnight at home using AC Level 1 or AC Level 2 charging equipment.
Inside virtually every phone charger is a transformer. Some of them draw some current even when the device theyre powering is turned off or in the case of chargers even when the phone or device is fully charged. An induction charger is two halves of a transformer with a coil in each section. If the charger is not actually connected to the phone but is still plugged into the wall-socket then there will be a very small amount of power still drawn but most phone chargers these days have a very low phantom power draw that can usually be ignored.
