On the occasion when I hear people talk about “vampire” electronics, I inevitably hear people talk about cell phone chargers, and how they’re sucking power even when the phone is not attached. Better unplug them and save power!
I knew this was overblown, but it’s really shouldn’t even be mentioned. Check out this table:
Cell phone chargers are such a small deal in relation to other electronics that the continued mention of them takes away from the bigger issue. They are two orders of magnitude less of a problem than a host of other “vampire electronics.” Or, in non-engineer speak, they are basically a rounding error in your energy use, and maybe even less. If you’re taking the time to unplug your cell phone charger every day to save a quarter every year, then you’re basically just a big old idiot. And shame on people, even actual utilities (such as where I found this table) who continue to mention this unused-charger BS.
