Does My Phone Charger Use Electricity. That electricity has to come from somewhere and. I measured it with no devices being charged just now.
But how much power does it consume. Chargers continuously draw power from an outlet even if your device is not connected. Although this amount could be as little as 25 watts imagine that over 4-5 devices combined for a year consume more energy than you passively consume.
For example if you still have a cell phone or other portable electronics device from the 90s its charger might continually use a noticeable amount of power if you leave it plugged inbut even that amount of vampire power probably wont make a noticeable dent in your electricity bill.
There is a charge controller chip inside the phone that determines how much current to put into the battery. Using a wireless charger took on average 2101 Wh. My son is always leaving his phone charger plugged in when not in use. According to my tests a genuine Apple iPhone charger uses about 130W of power a month which equates to 15KW h a year or 018 on my power bill.
