Looking for a case with battery packs
I am looking for a case for my iPhone X that has battery packs I’m in the field a lot not near power looking for something that I can detach and charge and swap out. Ideally I’d have one fully charged on my phone and an extra in my bag charged then both would charge at night.
The closest thing I have found is this case

But it doesn’t give the option of ordering a 2nd battery. Anyone have solutions
