Hear me out. I am not looking for a battery pack that can charge your phone wirelessly but one that can be (re)charged wirelessly. So if I need to recharge it over night I just put it in its pad but use cables when I’m charging a device with it. It’s because the only device I have now that supports wireless charging is my phone but I hate the hassle of having to connect the battery pack which I use for various devices all over my house as needed such as Kindle, PS4 controller etc. With wireless charging I would leave it on its mat whenever not in use so I’ll have access to a fully charged pack when needed.
It’s impossible to find since google always shows chargers that charge wirelessly. Can’t really blame it English is an convoluted language. I also find many that do both, ie wirelessly charge other and get recharged, but they’re expensive and can only supposed 1-2 cabled devices which is annoying because I have more cabled devices.
You can get wireless charging pads that look like a sticker with a micro usb on the end. Tend to use them for making phones wireless charging capable.
You could probably use that with one of the shop bought battery packs that takes a micro usb for charging (like the Poundland battery packs, but better)
You could probably make your own using a normal battery pack and one of these wireless charging receiver pads, just stick it onto the battery pack. A bit of a mess but should work fine.
