Wireless charging is nice, but maybe some people are looking for a more environment-friendly alternative: There’s lots of powerbanks available where you can exchange the batteries when they start losing their capacity, they typically run on common 16850 Li-ion cells (the ones you can find in a Tesla, or in electric bikes and scooters)
Tomo has many of different models, xtar has two.

And for anyone looking for the PB2S, here it is on Amazon:
