Does A Phone Charger Use Electricity When Not Plugged In. If you thought simply having your phone charger plugged into a wall outlet all day was running up your electric bill then think again. Many devices such as a table lamp or radio are turned off but not all devices.
A charger basically converts AC to DC to charge the device connected to it. No measurable draw when disconnected from camera around 8 watts while charging. The mobile phone chargers I tested all consumed 01W or less of electricity when left plugged in and not charging a phone.

I mean five chargers costs you about a buck a year. So the charger would take that 220 V and c. In such a situation the charger will still draw a minimal current from the mains and the regulator will maintain a steady supply of 5 V. The mobile phone chargers I tested all consumed 01W or less of electricity when left plugged in and not charging a phone.
