I bought a previous model from this company and I liked it so much that I wanted another tire pump for my other car. But I love the fact that this one comes with a regular plug! It is good for basketballs, soccer balls and other inflatables. It's a lot easier than running through a car outlet. I had to use an extension cord to get to all my tires because the power cord was a bit short, but that's not a problem. If you prefer to use a car power adapter, there are enough cables for that. Adjusting the tire pressure is very easy and when you connect the air hose to the tires it will show the actual pressure in psi. All you have to do is set the desired psi level and forget about it because the pump will turn off when the desired psi level is reached. The pump is small and light enough to pack in a car. It works fairly quickly, inflating 5psi in less than a minute. I have had a question before and contacted customer service and so far have been very happy with them. This pump is a real find! And the best. No more trips to the gas station just to pump air!
