its compact and easy to use. picture directions included did not match item. In spite of that it was easy to figure out how to use it.

Tried it for inflating a volleyball that I have. it doesn't seem to be super accurate with low pressure measurements. since the volleyball is supposed to be inflated to 4 - 5 psi and when the pump was set to that it inflated for a very brief time, and the volleyball felt under inflated. I'll test again with my car tires, to see how it works for higher pressure readings. and Update again then.

Works as promoted. I have used it 2-3 times on the battery in the last month since I received it. Fills the 2-3 PSIs I need to maintain the tire pressure. However, have not had to use the product for more than 5 minutes up till now or connected to the The rechargeable battery seems decent enough. Decent build quality. The only reason I am giving it a 4 Star is that I feel the description was not clear on the AC power part which is what I wanted.

Charge it 5 hours then it works fine ( four tires total about 21 psi inflated) ! Became hot after finishing . The hose is too short but workable. For the price, I will not complain about the cheap plastic so on so forth. After all it is a portable light duty pump.

Excellent light-weight tire inflator. This inflator is small, but sufficiently powerful to quickly top off your auto tires. Further, the carrying case makes it an asset for taking along on road trips. However, it definitely shouldn't be used for full-sized pickup tires or anything larger. Finally, I would have given it an overall five-star rating had the air hose been about 1.5 feet longer.

I've had this for a few months and have used it to top up 12 tires without recharging (and it still showed itself as having quite a bit of charge left). It performs well at higher pressures as well--I've used it up to 42 PSI personally. It's far more accurate than the air stations I've used at gas stations in the past. Other reviews have stated that it does not have an auto-off feature. They either received defective units or were not setting the target pressure correctly, as it has stopped when it reached the target every time I've used it. I've subtracted a star from my rating due to other reviewers' mention of the company's attempts to bribe other customers to remove their negative reviews. This is unacceptable and s the sole reason why I haven't ordered a second yet

*Update. Received a replacement from the company after posting this review. Updating my star rating. Original post: This product is Garbage. Used for the first time and it dies after 2minutes. Charged up completely, but unable to fill even the most basic pool floaty. I can’t even imagine trying to use this to fill a tire in an emergency! And I can’t return it :(
