Kensun AC/DC Power Supply Portable Air Compressor Pump with Analog Display to 100 PSI for Home (110V) and Car (12V), Tire Inflator with Adaptors for Cars, Trucks, Bicycles, Balls

This product works great. I read through a LOT of reviews, both good and bad, for this product and many similar options before deciding on which to buy. One thing I have seen a lot is that people seem to think these small, under 1lb machines will operate as quickly as the giant ones you go pay for at gas stations. If this is what you're expecting, you'll never be satisfied with any model. Airing my van tires up from about 20psi to 40psi takes about 5-7 minutes per tire when using the DC (car power) option. It may be faster if you can use the AC (wall plugin), I have yet to try that way. But it's easy to use, comes with clear instructions, and ultimately gets the job done. Yes, fitting the cords back in their compartments isn't the easiest thing in the world, but they do fit and the whole thing goes back into a convenient carrying case. I kept this in my van over this winter and had no problems using it any of the times I needed to pull it out. Very happy with this purchase.

it works great. i use it on the AC side mostly and the dial really helps. you can watch the pressure as it inflates and don't have to stop and check with a tire gauge

Update: A couple of days after I posted the review below, I heard from Kensun (via Amazon) offering me a full refund for the purchase in light of the missing DC cord. I applaud Kensun's prompt and responsible customer service, and have upgraded my rating from 3 to 4 stars in light of it. (The pump is a good, but not especially outstanding, unit that served my needs well, so I would have given it 4 stars from the start if the package had been complete. Lacking a DC cord of course made it less useful, and would have been completely disqualifying for many users, and I originally downgraded it accordingly.) Original review --I needed to move a car whose tire had gone flat by the next morning, my ancient bicycle pump failed, and this one on Amazon was reasonably well reviewed and available same day if I ordered immediately (just before 5pm) Kudos to Amazon for delivering it a few hours later! The pump is simple, plasticy but seems sturdy, and dead simple to use. It was somewhat noisy and took about 5 minutes to go from a few PSI to just over 30. The unit delivered did not include the DC (car cigarette lighter) power cord described online and shown on the box.

Good buy and works great. Its easy to use and a great value for the money spent. I wouldn't hesitate.

Good quality had to pop a lawn tracker tire back onto the rim worked great.

DO NOT BUY THIS PRODUCT. It's garbage. I was excited at the thought I could plug in an air compressor into the wall - but it's garbage! If I could give this 0 stars I would. Bought this & used it once with some difficulty as it does not inflate like a regular air compressor - it took forever to inflate a kid toy. Went to use it again & it just stopped working ran for 30 seconds. There is a phone number on the bottom of the kit that goes to nothing - call doesn't go through & the number Amazon provides also doesn't work!

I used this product a total of 8 times before the hose developed a leak at the valve stem connector. The air gauge reads about 4-6 PSI low. My previous compressor was inexpensive and lasted about 12 years. My next compressor will NOT be a Kensun.

My horse trailer has been sitting, the spare was down to 14 psi and the rest of the tires were at around 20 psi. I got this today and filled all my trailer tires and the spare to 65psi. Took about 10 minutes or so per tire. Now that I'm ok with my psi in each tire, it won't take as long next time. It definitely did the job, the housing stayed cool, and I ran it on AC power as it's parked next to my garage. I am stoked to have this as it's a hassle to fill the tires at a gas station, providing that the air pumps even work. I may get another one to keep in my car. Only gripes are no preset, so you need to keep an eye on it, and the gauge is a bit difficult to read, but I checked the pressure with another gauge and it's spot on. Definitely can recommend this little pump.
