Look... I tried it in a car, it does the job. It gets power from the cigarette lighter. I increased the pressure from 25 to about 31 in about 5 minutes... What should be noted is that it requires patience... It inflates slowly but relatively steadily... So, it requires patience and caution not to overheat... It claims to inflate a flat tire in 10 minutes with a overheating time limit of 20-30 minutes where you turn it off and wait for it to cool down before continuing...
The price is a bit high...
As for the construction, it's generally okay, not like some other cheap ones, the pressure gauge is okay... I think other cheap pumps don't even have a pressure gauge... The valve attachment is okay... Screw-on... That's good... Not clip-on like some other pumps that happen to be plastic and break... I preferred this one mainly because the attachment is screw-on...
And one last thing... It makes noise...
Not as much as some others that you can hear from 3-4 blocks away, but it does make some noise, albeit less... Overall, conclusion, okay... I think I'm satisfied...
Oh... I forgot to mention that the hose that attaches - hides in a recess of the pump is a bit short...
I would have liked it a bit longer...
As for the pros, I forgot to mention the LED flashlight... Not that you can see anything... Only the valve on the tire... Not even the pressure gauge...
Additional flashlight and cover your ears until it's filled...
