Review on Kensun 12V DC Portable Air Compressor Pump - Enhanced 150W Digital Tire Inflator for Cars & Inflatables: Efficient and Reliable Performance by Corey Michaels

I'm giving 4 stars as it worked better than the smaller mini pumps I've had in the past, however initially didn't work when I took it out of the box. More efficient as it inflates faster and isn't as hot after use as the smaller units I've had. I inflated a car tire in under 2 minutes and increased the pressure a few pounds from 31 pounds to 34 pounds on my car tire in under 3 minutes. It has rubber feet to keep it in place and a threaded air connector, which takes longer but is a more reliable method of adding air. A small carrying bag is also useful. I should note that it didn't work the first time. I replaced the fuse and everything seems fine. I contacted the seller who was quick to reply to my email with an apology and 2 replacement fuses. Overall I am satisfied with the first use.
