Xiaomi Air Inflator Tire Pressure Tester Pump Electric Car Air Compressor Hand Held Tire Pump Led Light LCD Display 2000mAh Lithium Battery150PSI For Car Bicycle Tires Ball and Other Inflatables

Functionality and design wise, this is a good product. The problem I am now having, 2 days after my return window has closed, is... The collar which screws the end to the Schrader valve, is two piece. Its a swivel so that the end can turn independently of the hose. The first issue is that it is very tight, almost impossible to unscrew fast enough, without letting out at least 2 lbs of pressure or having to turn the hose AND pump assembly. This is annoying and very impractical, but knowing this you can simply over inflate to compensate and let air out after. This of course fefeats the functionality of the auto stop and any hope for some accuracy. Now, I had only been using this on bike tires which had no issues. Today I patched a nail hole in a radial and when I used this pump to get the pressure to the desired psi, 33lbs, the collar began to leak, profusely at a messily 15! The pump is now completely useless. I will contact the seller/manufacturer, and hope for a replacement, although my hope for a second product is a little low... If I am refused, I will dispute the charge on my credit card and both amazon and the seller will lose. I would recommend a pass on this until I find remedy from the manufacturer or seller. UPDATE: The seller was impossible to get a hold of, and directly attempting to contact the manufacturer was a waste of time. Im the end, Amazon came to the rescue and accepted the return and refunded my $. My search for a nice, working pump, continues.

Holds very small charge, inflates to accurate PSI which is awesome, but charging port broke after the 5th charge. I used the charger provided. Baffled.

I liked how small and sleek this looked so had to try it. Plugged it into my SUV set the target air pressure and let it go. It worked well. Took longer than another - much larger - air pump I have, but I left it to do its job and it automatically switched off when it hit the target. I am impressed that this little device managed to get the job done. Kept it in my car for emergency use - and for the next big inflatable for beach/holiday use.

Handy tool and it is nice and compact. Great for using with my OneWheel, Mountain Bike, or Car! I can charge it with my Jackery power supply and this is a great addition in my off the grid camping gear!

AFTER TWO TIMES THAT I USE IT SPORT WORKING.AND BECAUSE IT PAST A MONTH FROM THE DAY OF PURCHASE IT DIDNT ALLOW ME TO RETURN IT.

Para su precio y la calidad que tenie se destaca....muy contento con el producto

El tamaño del equipo es súper conveniente; tiene mucha potencia; fácil de utilizar (intuitivo), materiales de excelente calidad. Equipo de alta tecnología para operaciones sencillas y cotidianas.

Amazing product I didn’t thought it can refill my car tires Great product

its only good for small things. I try it for my car, it takes way too long just to have only 2 psi

Another made in China piece of garbage. After just a month, it doesnt charge anymore.
