  Pros: easy to use, high portability, reasonably fast, turns itself off when air setting is reached

  Cons:

  Summary: This device is powered by either 120V AC or 12V DC. I use it exclusively at home with AC, so I do not know if the performance is different with DC. I got this portable electric air pump to refill my car tires while at home. I have always had problem filling up the correct amount of air because the air in the tires were not cold because I have driven around to a gas station, so I figured filling them up at home would be a better measurement. This device is easy to use. Just plug in power, attach air line, and turn it on. It shuts itself off when finished. The first time I used it, my tires had around 30 psi, and I needed the tires to be at 35 psi, which took around a minute to fill them. This is a lot slower than at the gas station, but I think it is reasonably fast and faster than the cheaper pumps that I have seen. Since then, I have only needed about add ~1 psi every 2 weeks, so it only takes hardly any time. It is a bit noisy but again less noisy than the cheaper pumps. This pump shuts itself off when it reaches the set air pressure, which I have not seen before, so you will not over-inflate by too much. What I do not like about this air pump? Well, the AC power cord is short; it is only about a foot long. It is stored inside a compartment along with an equally short air line. The DC input has a car lighter adapter with a very long cord. Since I use AC power with it, I have to whip out an extension cord. The air line has a plastic lock level, which does not look very strong, so I have been a bit careful about not breaking it. The air setting dial is tight and stays in place, but the graduation scale on it is crude. Use an electronic tire gauge afterward because the scale is around + or - 2 psi. This device would be much nicer if it had a more accurate, built-in digital readout for gauge and setter.
