just get the Xiaomi pump, it's supposed to be great. And if you can't get it, get any other battery powered pump like these:
and also there comes an extender valve with the Max for the rear tire, because you can't fit the pump directly, but this extender is shit, because it has no stopper at the end - so as soon as you screw it on, air starts to leak out! Just buy an extender valve with a stopper, they are fairly cheap!
yeah just a wrench will do. i have this electric battery pump but don’t always ride with it, only longer trips away from civilization.

I have both rhino liners inside the tire and flat out in the tubes so i feel pretty well protected…my riding is mostly on bike paths and gravel so also not encountering the worst of road debris like i would if i was riding in the breakdown lane of roadways.
