Does it stop on its own at the set pressure?

Yes. You set the target pressure and the compressor shuts off automatically when the tire reaches it.

Can it inflate more than car tires?

It inflates up to 100 PSI, which covers car tires and many bike tires, balls and inflatables within that limit.

Does it need a battery or charging?

No. It runs from a car's 12V accessory socket through its 9.8-foot cord.

How do I know the pressure reading is right?

The digital screen shows the pressure in four selectable units; check it against a separate gauge if you want confirmation.

Is it good for nighttime use?

Yes. The backlit screen and one-press LED light are made for low-light roadside work.
