Does a charger that is plugged in but has no load use energy?
- raintrees 13y agoYes. Also, heat is another way of consuming power...
- dchichkov 13y agoLol @ stackexchange.com: Inside virtually every phone charger is a transformer. Transformers have a finite resistance, and hence there will always be current flowing through them if they are plugged in, even if there is no load (i.e. nothing charging). That's basic physics. Basic Physics. LOL. And how that charger works with both 110AC and 230AC ;) ?
