I'll try to keep this brief.Received item well packed. All components present. I recharged the battery to full, as I had a big test for it. Endurance was the key. I had a spare tire that was neglected for 9 years without being checked. Sure enough, it was at 24psi when it should have been 60psi. While this isn't a practical way to refill a tire, I wanted to push it and see how the compressor would perform. I pre set it for 60psi, and fired it up. I'd estimate it ran for 15-20 minutes give or take, and the overheat prevention system kicked in and shut it off. Nice! The unit felt warm to the touch, but not hot. The pressure was then at 46psi at shutdown, still 3 bars on battery. I waited 15 minutes for it to "cool down", and resumed. It finished the job and stopped promptly at 60psi. My pressure tester read 1-3psi higher; no big deal. The battery was now exhausted, but, mission complete!Minor caveats: -LED screen hard to read in daylight. I recommend you preset in a darker lighting setting. -Hose could be longer; biggest drawback. -The air nozzle is the best; screw on's are difficult. However, make sure you have a snug fit on stem or there will be leakage. Listen for hiss before engaging unit, make adjustments as needed. -Unit vibrates like crazy etither standing upright or laying down. Quick fix is to put a cloth OR storage bag underneath to stop the vibration of the unit.This is one of the best purchases I've made in a while and highly recommend. The price is unbelievably low for the quality! I'll be buying another one for my spouse's car. BUY IT!

I am from the old school and either use a hand tire pump or my compressor in my garage to inflate anything that needs air. That is until now. I wanted something easy to use that I could carry in my trunk or a backpack when riding my e-bike or motorcycle. This little pump is a dream come true. It is easy to use and the accuracy is incredible. No more putting some air in my tires then checking with a pressure gauge then more air and checking again. It shuts off when the desired pressure is reached. Then your done. My first use was for two motorcycle tires and four bicycle tires. It inflated them all with one charge and still had two of the three bars that show the remaining battery level left when I was done. It did not overheat, but was only slightly warm. It recharges quickly and packs away in a nice drawstring bag. I absolutely love it.

Love the size even though it is a bit heavier than expected. It is very easy to use and keep at hand. We are campers and I bought this to use while we’re were away from home and had limited space. Perfect!

El inflador en general es bueno, lo que no me gustó es que tarda demasiado en inflar una rueda de bicicleta, la mía aro 29 tardo aproximadamente 10 minutos, y no estaba tan desinflada, lo demás todo bien, llego bien empacada y completa.

So far great! Used it to check and add air to my Spyder tires. Quick and easy. Taking it on a road trip this summer.

Nice size

This battery powered pump is very portable and light. It can easily be held in one hand. It was about 50% charged when I received it and it took about 4-5 hours to fully charge. I was able to inflate 4 large SUV tires from about 35 psi to 40 psi using about 1/3 of the battery capacity. The connector hub from the hose to the battery got hot to touch after filling all 4 tire. The one issue that someone else mentioned is the short hose length. You have to support the unit so it doesn't pull on the tire air valve. If there is tension on the connection it can produce an error in pressure reading and cause a premature cutoff in pump inflation. I would take the digital reading of the tire pressure as an estimate since the number can vary a few psi depending on if the air valve has any tension on it from the hose. I would use a regular tire pressure gauge to more accurately measure your tire pressure after inflation. Other than that caveat it is a great portable device for inflating car tires (there are connectors for inflating a ball or pool blow up toys and a wire connector for car cigarette lighter but no connector for wall outlet).
