Review on Convenient Portable Air Compressor for Car Tires: 12V DC Mini Tire Inflator with LED Flashlight and High Definition LCD Screen, Suitable for Car Bike Tires and More Inflatables by Travis Coffman

I have to admit I was surprised that it worked so well given its small size. I have two oversized golf tires inflated to 20psi and two road tires to 60psi. The golf cart was 17psi, but the road bike was almost flat. Small enough to fit in a glove box. The power cord easily reaches your front wheels, but it can be difficult to reach the rear wheels on a medium to large vehicle. I didn't read the instructions and it was very easy to use and understand. Highly Recommended
