Do cell phone battery chargers use power when not charging batteries?
On good morning america this morning a lady said that cell phone chargers should be unplugged from the wall when not in use because they use power all the time. True or not?
They do not actually use any power, since there is nothing plugged into the other end to consume the electricity. There is no flow of power from the plug to the end of the terminal that connects to your phone while it's not connected. But....there is electricity flowing through the box part of the charger and that causes heat. This may be what's raised your question as to whether or not it's using electricity. But if you're really worried about it, I'm sure there are many more items/appliances in your home that use some degree of electricity even while idle.
