Quite impressed

Shipping was super fast - arrived next day. I'm quite impressed with it so far. Very simple to use - just push the plus sign until you reach the pressure you want the tire filled to, attach hose to tire, and push start. It will stop automatically. I put roughly 10-13lbs into each tire and it took about 3-5 minutes per tire. The battery did die after the third tire, but honestly, I wasn't expecting it to last that long. A few minutes on the charger and finished the last tire.

I am overall pleased with this compressor. It is easy to use, portable and well built. It is excellent for for topping up pressures say 5 to 10 psi on 4 tires. If you are looking flat to say 30psi it will not handle 4 tires in one charge. For the price it is excellent for bicycle, golf cart, and car but it is NOT a professional mains driven air compressor.

Instructions could be better on short press or long press of the main buttons. Long press of the center button turns on and off the main screen, and short press the center button to turn the compressor on or off with the trigger button. The battery charger light turns from red to green when it is fully charged. A button on the front of the battery shows the charge state also. The main cause of battery and compressor failure is over-heating. There is a ball inflator needle, an air bed inflator attachment and an adapter for racing bike tall valve stem tube inflation. A 12 volt cord is included, so the compressor runs on 12 or 20 volts.
