That’s not physically possible.
But it is extremely efficient for what it is. The first number I found on google said it’s 95% efficient.
Comment on Other than a faulty charging port, is there any reason to use a wireless phone charger over wired?
ReanuKeeves@lemm.ee 11 months agoDoes it charg as efficiently as a wired power bank?

That doesn’t sound correct, considering the amount of wireless chargers that will take 10W, but can only deliver half that to the phone.

Are those qi2 chargers or qi1? The magnets make a huge difference.

Not even close. Ifixit did some testing, daily MagSafe wireless charging uses 36% more energy than a wire (which includes idle power draw). It also means slower charging.
