When you want to buy a wireless charger, you may notice there is some mark for 5w/7.5w/10w.
What is the meaning for this?

Base wireless charging starts at 5W, but most phones support some kind of fast charging. Apple’s iPhones are designed to charge at a maximum speed of 7.5W, Samsung’s phones charge at 10W, and other Android phones support up to 10W.
