First Impressions of the air pump in use
I dropped pressure in one tire from 35psi to 25 psi and began using the inflator to bring it up to 36psi.
The pump ran for a long time, I did not time it. The noise level was low. The tire looked like it was fully inflated, when the pump said 31psi. It was actually 39psi… iow, the pump reads 8psi low…
I then used the pump to add 2 psi to the 3 other tires. The pump stopped working a few times, probably cause it was hot. I burned my fingers on the metal part of the hose.
The buttons are absolutely terrible, I cant tell when Im pushing them, and a lot of times they dont seem to work at all.
I think this pump is handy for adding a couple psi to each tire, but I would not expect it to be capable of adding 10 psi to each of 4 tires.
I brought the pump into the house and plugged in to charge. The display said the battery was at 60% capacity. The total psi added to the tires was 16psi… to my mind, the unit would be out of battery after providing a total of 32psi…
I like the convenience of being able to add a couple psi to each of 4 tires, without having to run the car motor, and without having to run a cord from my cig lighter to the pump. I tend to change my tire pressures a few psi up or down depending on the time of year.
This unit will not replace my Viair, for those times when I am offroading, I take 10 psi out of each tire when im on dirt and rocks… But the Viair requires running the motor, and clamping direct to the battery. Not very motivating when I just want a couple psi more air, to fine tune the ride of the car on highway.
trivia, the pump comes with fittings to inflate a basketball and bicycle tire. They store in the base of the unit. However, the charging cord has no storage location… I put a rubber band around the body, to hold the charging cord.
I do not recommend the pump, for 2 reasons, the buttons are really difficult to use, and the air pressure gauge in the pump is off by 8 psi.

next test pump…
I ordered this pump with a Vipon coupon for $22

Im hoping the pressure gauge is more accurate, and the buttons easier to use.
