How do I set the pressure?

You set the target pressure on the digital display with the red buttons, then let the pump run until it reaches that figure. Check the reading against a separate gauge now and then.

Does it need a battery or charging?

No. It draws power through the cigarette lighter plug, so it only runs while connected to a 12V socket with the car on or in accessory mode.

What can it inflate besides car tires?

The included nozzle attachments let it fill bike tires, sports balls and air mattresses. The valve connector fits standard Schrader valves.

How does it compare with a cordless inflator?

A cordless model is easier to carry between cars, but needs charging and loses power over time. This one runs as long as the car socket supplies power but is tied to the vehicle.

The inflator with its hose and cigarette lighter cord, several nozzle attachments and a replacement fuse.

Can I leave it plugged in?

Unplug it after use. Leaving it connected can drain the car battery, and the pump should cool between tire fills.
