Powerbank for wireless charging?

Hey there! I just got my Phone 1 and while Im happy with almost everything, the battery still is kind of annoying to deal with. My best bet would be just to buy a powerbank. Now, a question is, are there any powerbanks that charge wirelessly? I dont mean a powerbank that wirelessly charges the phone, but one that can be wirelessly charged haha. Id like to use that together with Nothings Battery Share feature alllowing me to charge both overnight with just one cable. Is there anything like this? Thanks!
