I needed a portable air compressor that was light weight and small enough not to take up much space in my car. Very often I pay very close attention to the tire pressure on the road and have to rely on the gas station's air pump, which usually breaks down or causes high maintenance costs. I bought a Yome Air compressor and was amazed at its performance. The twin cylinders certainly made a difference. It pumps up pretty quickly. I took the opportunity to compare the built in meter readings to the mechanical ones I carry with me and they were very close to the two readings I used as a reference. All I had to do was move the power cord from one side of the car to the other (I drive a large van). Most likely, there will be no problems with small cars. In fact, the kit included an extension cord. The only thing I doubted was the preset pressure I put into the controller. I just didn't want to wait for the pump to stop on its own and hit the shut off button when I saw the tire was inflated to the correct pressure. In general, I liked the product. It worked much better than others I've bought before that went in the trash after a few failed attempts.
