All chargers suck energy while plugged in. Not necessarily a ton of power, but just about all AC->DC conversion involves inductance and rectifiers that trickle juice constantly.AcutancePhotography said:My wife has one of these wireless charging toothbrushes that she never unplugs. I assume that is also eating power 24/7?
If the toothbrush really is wireless charging, it may have some kind of sensor to turn off when the brush isn't there. Depends on the design. If there's no visible switch or weight-based sensor, then the only thing that could sense the toothbrush would be some kind of electrical field (think like those security gates at a bookstore) that senses the introduction of the chargeable device. That field would be continuously using power.
Hook a kill-a-watt up to it and see what it's drawing. Then figure out whether it's worth it vs. the annoyance of plugging and unplugging.
