Oasser 12V Air Compressor Tire Inflator Cordless 2000 Battery Air Pump for Cars Motorcycles Bicycles with Digital Pressure Gauge USB Charging 120PSI P2A (Black)

This is easy enough to use for topping off a low car tire. My only issue is it doesn't have enough juice in one charge to completely fill a tire if it's basically flat. But if you live in a northern climate, you know that sometimes tires lose a few pounds of pressure in cold snaps, then this thing is money for doing just that. It's small and it couldn't easier to use. Hook it onto the valve stem, set your desire PSI, and pull the trigger. Presto. I think it's off by a pound or two (e.g. I set it for 30 and after it got to that point, my tire gauge read it is 28), but once you calibrate yours, you can make whatever adjustments are needed. It certainly beats going to a gas station and praying their air hoses aren't frozen!

It is a nice product.

If you ever tried to get air from a "no good" air machine at a gas station, then you will really appreciate this product. It is solid, durable, and fast. It charged in about 4 hours. I first used it on my bike. It did both tires in less than two minutes. It was probably under a minute each if you count the set up time. My wife saw it and after I showed her what it did, she immediately ordered one as a gift. This is like the top of the line of air compressors. It also comes with a real nice pouch for storage. I have also ordered one for my wife. This is one gift that I am sure she would like.

This battery power air compressor is very easy to use. I use it to top off the air in my car tires when they go low. I really like the display on the air compressor, it shows some important information like the battery life and air pressure. I really like the feature to set the max air pressure you want and once it inflates to that pressure it will stop pumping air. So far i have used it to put air in the tires of my lexus, hyundai and tacoma truck. Comparing this air compressor to my cigarette lighter air compressor, this one gets 5 stars for being cordless.

I have used It for several weeks, so far it has worked well.

The hose that connects to the compressor and tire does get very hot; must be careful removing it from the compressor.

Battery lasted 6 months, turns on but it dies with in seconds, product is trashDo not buy

Not bad. Shut off is a bit delayed, though.
