Does it stop on its own at the set pressure?

Yes. Dial in the target pressure and the inflator shuts off when it reaches it, within the gauge's roughly ±3% accuracy.

Can it inflate truck or RV tires?

Only up to 120 PSI. Many light truck tires fit, but heavy-duty and some RV tires need higher pressure and a different inflator.

The hose is Schrader only. You need a Presta adapter for road and some mountain bike tubes.

It depends on the kit. Some bundles include a 4.0 Ah battery and charger; tool-only versions need an M12 battery you already own.

Flow rate is 0.88 cfm, so a typical passenger tire top-off takes a couple of minutes. Filling from flat takes longer.

It trades speed for cordless convenience. A corded compressor fills faster, but this one works anywhere you have an M12 battery.
