Cordless Tire Inflator,Air Compressor Portable CordlessTire Inflator with LED Light Digital LCD Li-ion 150PSI 12V 2000mAh, Portable Air Pump with Pressure Gauge Battery For Cars, Motorbike, Basketball

So I really haven't put it to the test yet but my first reaction is it seems kind of chintzy for the money. I charged it and tried it out to make sure it worked and it did seem to produce pressure. I think it's good for adding a pound or two to your car tire or pumping up a bike tire but I am not sure beyond that. And I think if you drop it on a hard surface it would break.

Does what it is supposed to do - with a few annoyances.-The built-in LED light is extremely weak. You should not count on it as a useful lighting source for using the device in pitch-black conditions.-The LCD display flickers while pushing the buttons, making it hard to read while adjusting the pressure/unit type etc... Don't get me wrong - it will not prevent usage of the device, but it can be somewhat annoyingThe LED on the charging cable is supposed to be green when charging and red when complete, according to the manual. On mine its BLUE while charging and red when finished.

No mention of how long it takes to initially charge the battery. While it works fine, it is slow to inflate tire.

The trigger mechanism to start the motor does not work very precisely-you have to fool around with it

The weather suddenly got very cold at night and I needed to get air in my tires. I tried four gas stations. Two of them had broken machines. The other two machines were terrible .. about +2 PSI only. After spending $4 , and wasting a good bit of time, I decided to buy a small compressor. I checked Amazon for the best I could find and bought this model. Problem solved!

I could not get the air pump to work after many trials. The manual is very skimpy. The manufacturer is listed as Aunis but the email and facebook site in the manual are bogus. The construction looks cheap. Not a quality product.

Checking the tire pressure on a motorcycle can be challenging. Accessing the valves with an air hose is a pain. This tool makes the whole process much easier. No more uncoiling the air hose, no more waiting for the compressor to fill and most importantly no more wrestling with the hose! Love this thing!

this air compressor is a piece of junk, used it one time and it broke. the owners manual is written in six languages but no phone number to call for a replacement or refund.
