my car tyre inflator basically consists of a mains powered compressor that is run off 2 large boat (or car) batteries hooked up to a Meanwell true sine wave 1kW inverter. That may seem like overkill, but actually works.
My car tyre inflator is called ATLAS COPCO and runs on 400V AC three-phase. For when I'm away from the garage, I've got a smartphone app that allows me to call assistane (AA / ADAC style but not tied to a membership) regardless of which car I'm driving and regardless where in Europe I am. But for a flat tire I don't. I swap it, since I've got a spare and tools in the car. And I check the pressure on the spare regularly.
My tyre inflator is just a good common sense one, one that I keep in its protective pouch in the boot, and it also doubles as a powerful torch. When required it simply clips onto the car battery terminals and has 2 switches, 1 for the compressor and the other for the torch, I believe in the KISS principle
KISS would be to do what I do, use a foot pump. One wonders if all this boasting about the size of one's compressor isn't some kind of compensatory displacement activity.
Now I am back to having a sand capable vehicle again I have a good one on the shopping list. Re inflating 4 large tires from 8-10 PSI to road pressure by foot is a workout I don't need I do have a cheapy direct drive compressor as well at home but doing shed things which does all I need at this stage.
Yeah; KISS Principle here was:
A) Need to air up tyres from winter storage.
1) Sit in front of PC with cup of coffee.
2) Find used 20 gallon DD air compressor for CAD$50 with hoses and a coffee-can full of accessories. Take your pick of oodles within easy drive.
3) Drive 10 minutes; buy it, have 10 minutes casual interaction with another human being for the first time in months.
4) Take it home and plug it in; still be done with the actual work part before I could foot-pump 2 modern oversized SUV tires with 17-19" wheels.
5) Enjoy not getting blisters on your feet.
6) Lather, rinse, repeat for however long your used air compressor lasts.
