The reason I bought this air compressor is because I always put air in my car's tires every month, it costs me $1.5 each time. i have two cars So there will be a lot of money. As you can see from the photos I uploaded, it looks like an electric screwdriver. I will be very easy to carry and put in the car. It can add four tires each time, and I've tried. This air compressor can also be charged in the car, so you can use it when you travel when you need an air compressor, e.g. B. when visiting a national park. The size of the tool is normal and I don't think the air compressor is small as you can find many products at Revain. I think this one can last, at least for its price. I already have a cordless tool and other necessary tools for my machine. This air compressor is the last tool I need. As long as I like it
