AstroAI Tire Inflator Air Compressor Cordless Car Tire Pump with 20V Rechargeable Li-ion Battery 150 PSI Portable Handheld Air Pump with 12 V Car Power Adapter for Cars Motorcycles LS40791（C1）

So far this has worked great. I havent had any flat tires on my car but I have used it to inflate a few bike tires and its working great for that. I have this along with my emergency kit and jump starter in the back of my truck. I may never need it but its nice to have just in case.

The portable tire inflator is very light weight. It comes with a rechargeable battery and a battery that plugs into the cars lighter port. Both slide off very easily. The instructions are easy to read and understand. There is a diagram that tells where everything is. Upon taking the inflator out of the box for the first time and just messing with it without looking at the instructions, it was really hard to tell what was the on/off button and what the other buttons were for because they are black on black. Some contrasting color would have helped with that, also if you are trying to use it in the dark you wont be able to read what button is what. However it is pretty self explanatory whatever button you chose. One turns on a flash light which is wonderful, the other is the on/off button, two are for more or less air and the last one is settings. Overall I am very pleased with the item. A carrying case would have been nice to put everything in too.
