In principle, wireless chargers can have very low power use when idle; I've seen figures quoted as 0.1mW i.e. over the course of a year 0.876Wh (so ~0.0009 kWh)

In principle, wireless chargers can have very low power use when idle; I've seen figures quoted as 0.1mW i.e. over the course of a year 0.876Wh (so ~0.0009 kWh). Of course, this will likely vary based on the specific charger in use. I don't think this is substantially different to the idle draw of a wired charger.
- acqq 6y agoThe practice is often very different from the principle. I’ve had a set top box that in the “off” state used 29 watts, 24 hours per day. In the “on” state it used 30 watts. In principle, it didn’t have to be so but it was.
