How long is the cord and hose for this tire inflator portable air compressor?

Hello Customer, The cord is about 10 ft, and the total length of the two hoses is about 2.4ft. It's long enough to reach your four tires.

Not sure I understand how this works. Do you plug the battery in your car charger slot? Then use it for tires?

It has a battery you can charge and use stand alone or charge and use with the car charger. Doesn't need to be plugged in to work just charged up. So charge it and leave it in the car and just check the battery level every so often

Can I connect it to a home electric outlet?

Regrettably, it is not feasible to directly connect the tire inflator to a standard home electric outlet. This car tire inflator specifically requires a DC 12V power supply to function properly. If you intend to utilize it with an AC (alternating current) electric outlet, you would need to acquire an AC-to-DC converter to convert the AC power into the appropriate DC voltage for the tire inflator's operation.

If I leave this tire inflator without operating it, will it automatically shut down?

Yes, it will shut off when it reaches you preset/desired tire pressure.
