Does A Phone Charger Use Electricity When Plugged In. Extension cords are an exception. Not only do you have the continuous current draw which honestly is going to be less then 500 per year even if the device is terribly inefficient but theres the likelihood of the socket failing and its not nearly as easily or cheaply replaced as a plug in charger.

18 watts alone 63 watts while charging MDs battery. YES Long answer. Perhaps you could try charging your phone in the daytime.
A device rated at 1000W running for one hour will use 1KW h while a device rated at 100W will take 10.
Power is priced in kilowatt hours KW h or 1000W which is 36 million joules of energy. According to the Energy Saving Trust any switched on charger that is plugged in will still use electricity regardless of whether the device is attached or not. So simply leaving one plugged into the wall shouldnt make a difference. What if a charger is plugged in but not connected to any device.
