Wireless power banks?

[KBC]

Anyone have experience with these? There’s a bunch out there that work with MagSafe, seems pretty appealing to not have to pack cables.
There’s a 5000mAh on sale at home depot in Canada for $20 right now I’m going to try out.

Any other recommendations?

I think wireless charging is inherently less efficient than wired charging (more energy goes towards creating heat compared to wired charging). I think it’s overall reliable, but personally I wouldn’t use the wireless charging because I want maximum power from the bank going into my battery, not being wasted creating heat during the wireless charging.
