Does my apple charger use electricity when plugged in but no in use?
I'd like to know if my charger uses electricity when plugging into the wall socket but not plugged into my iPhone, ipad or iPod? Thanks

No, it does not. When first plugged in, there is a brief ½ second, one tenth Watt reading, but quickly goes to zero when nothing is attached. This is expected behavior for intelligent, energy conserving power supplies.
The resolution of my Kill-A-Watt meter is 0.01 Amp, or 0.05 Watt, so it's possible it may have a minute draw below that resolution, but that would be negligible and not considered a "vampire draw," like older technology.

Yes it will. However, the current will be very little.
