I was wondering. I haven't really driven much since the apocalypse. How much electricity does the wall charger user when not in use? Probably minimal for the green light, and probably insignificant. Just curious.
I don't know what v2 uses, but my v3 uses 1W while idle, which is amazingly low for it having an offline power supply in it for running the electronics. They put some serious engineering into making that have such little loss (so says this electrical engineer).
