Does it shut off automatically at the set pressure?

Yes. You set the target pressure on the LCD and the pump stops when it reaches it, so you can watch the tire instead of the gauge.

Can it inflate more than one tire in a session?

Yes. The dual motors and twin cylinders are rated for up to 40 minutes of continuous work, enough for several tires in a row.

Will it reach the tires on a large truck or RV?

The 16.4-foot air hose and 11.5-foot power cord are sized for heavy-duty vehicles, so you can leave the pump near the socket and still reach each wheel.

Does it work on bike tires and sports gear?

Yes. The box includes a Presta-to-Schrader adapter, two air nozzles and a needle valve adapter for bike tires, balls and inflatables.

Can I use it from a wall outlet at home?

No. It runs on 12V DC power from a vehicle's power socket, so home use requires a 12V power supply.

How accurate is the digital gauge?

The LCD shows pressure as you inflate, and the automatic shutoff relies on that reading; check with a separate gauge if you need exact numbers.
