You will get consistent tire pressure every time.- A convenient LED light included

It just reinforced with me why when I've used these inflators, why I always double-checked with my more reliable hand-held tire pressure

I have a Mercedes where the tire light is always coming on, having this pump makes it easier and saves time getting the tires to the correct pressure.

I can check my pressure and top off my air with one connection.• Being able to set my target pressure means I don’t have keep checking my pressure and adding more air, and checking and adding, and checking and adding, etc.• Being able to power my inflator with a 12V accessory outlet means I can check and fill my tires in a safe or desirable location… like in the shade,

Being able to preset the desired pressure using the buttons and the digital display makes is easy to set the right pressure consistently

Accurate pressure matches psi on my on board tire pressure sensor.

I was just tried to top off my cars tires' pressure to 44psi

LED pressure gauge is accurate

and I just had to adjust the right pressure and press power it will stop when it gets to this number

Very accurate gauge that cuts off at the right pressure, and I did verify the accuracy of the final pressure against another gauge.
