Can this charger charge while plugged into a wall outlet?
What’s the wireless charging speed of these? Qi 2? 2.1?
Standard speed not fast charging but works fine
Man, wish I hadn’t bought one from Woot for $17 like two weeks ago when I could get two for just a few bucks more now. Especially since mine is still in transit.
You could always get these and then gift the other one to someone come their birthday or the holidays.

No, maybe.
This is a battery, not a wall powered charger. It comes with a charging cable that needs to plug into an existing wall wart or similar. It might be possible to charge it through one of the USB ports and magnetically charge your device, but it would be way faster (because this is NOT a high speed mag charger) to plug into the wall.
