>you do realise that the OP has like 2 weeks supply of batteries for camping or apocalypse, and if ‘off grid living’ is your use case, it’s a slam-dunk?

I will admit, the main bottleneck is that I only have 3 battery dock chargers. So unless I'm planning on needing it, half of those batteries are charging or dead at any given time.

I'd bet I could be camping for a month or so with the batteries I have if I really put my mind to it.

To others' point here, they even make solar topped rucksacks now. One of those, feeding a powerbank, and you top off your trailmap-photo-gps-emergency-sat-beacon gizmo on walkabout, no fiddling.
