Kiasaki BEST Digital Tire Inflator - Portable Air Compressor for cars with Tire Gauge. High pressure 12V car air pump - Up to 150 Psi, Automatic Shut Off & SOS Flashlight,Carry Case Bonus

I have a 21-foot class-B RV with the following tires: 225/75R 16C (these tires have a diameter of 29.3", a section width of 8.9", and a wheel diameter of 16”)Front tires are supposed to be 65 PSI and rear tires 80PSI (when cold).The RV tire sensor would tell me that (at least) one of the tires was under-inflated but whenever my wife and I stopped at a gas station, the tires would end up with less pressure than we started out with! This would occur because the gas station inflator would fail to reach up to 65PSI (let alone 80). So we decided to buy our own portable tire inflator and selected the Kiasaki.Its 12’ cord would not reach the rear tires, so we bought a 14’ male/female cigaret plug extension cord and with that we could reach the rear tires.I timed how long it took:- Kiasaki filled back RV tire from 62 PSI to 80 PSI in 18 min- Kiasaki filled front RV tire from 56 PSI to 65 PIS in 12 minI did both front and back tires by running the Kiasaki 50 minutes, mostly continuously (just stopping to unscrew and re-screw onto the next tire).It stopped automatically when reaching PSI specified but would stay on PSI specified for about 2 or 3 minutes before it stopped on its own.It did not have to stop due to overheating.Don’t know how good the long-term durability of Kiasaki is because this is the first time I've used it but it worked very well on topping off all 4 large RV tires, which require a higher pressure than normal auto tires.

Best thing ever!!! I worked at a trash burner power plant and we ALWAYS got nails in our tires so I had to inflate them A L L. T H E. T I M E and my compressor that came with my car I always wondered why there couldn’t be a way to set it to stop at my tire pressure.....fast forward a year and I hit something so my rim wouldn’t allow my tire to hold pressure so I used the old one so much it stopped working and forced me to find this gem! It’s uh-mazing, and works just as described!! My only complaint is it’s kinda loud so I have some reusable ear plugs if I need to stay by it. It would also be nice if it was waterproof, I wrapped it in a grocery bag because I had to use it in the rain.

Compact and powerful compressor that's simple to use. Plug the amply long cord into a cigarette lighter outlet and screw the air hose onto a tire valve. The current air pressure shows on the digital display. Press the increase or decrease button to change the display reading to the desired pressure then press the on button to begin pumping. It shuts off by itself when the pressure is met. I've had 2 other compact portable compressors and this one is slightly less noisy and faster than the others. It appears to be a well made lightweight plastic unit with a thin carry case. The unit functions exactly as advertised. I've inflated a few car & truck tires to 38 lbs, bike tires to 50 lbs and wheelchair tires to 40 lbs. Works good. The air hose is the screw on type rather than press on and latch. When screwing on and off some air escapes before I can get the fitting on or off completely. To compensate for the loss I've had to inflate a pound or two more which works. The screw on type is a lot smaller than the press/latch type and will fit in places the other won't. For example I had to have the screw on type for access to the wheelchair valves. I really like the auto shut off! All considered this is a good little compressor for the money ($37.97 on sale) and indications are it might last for a while. Recommended.April 5, 2018 - The compressor is still working as expected. I did purchase a small press on and latch type connector attachment that eliminates air loss when attaching and disconnecting the compressor to inflate tires and the like. Works great.

I immediately used your air pump to inflate my car tires from 37 PSI to 44 PSI as recommended by the tire and auto manufacturer. The first two tires were elevated to 44 PSI as indicated by the pressure gauge. The second two tires were elevated to 44 PSI according to the gauge, which took an extended period of time. That seemed strange. The hose was very warm to the touch, which I did not pay much attention to. However when I turned on the engine the next morning the car's pressure reading registered 51 PSI for those last two tires. I immediately reduced the pressure in those two tires to 44 PSI. The tire pressure has remained at 44 PSI for all four tires for days now.My concern is that I cannot depend on the pressure gauge's accuracy.Any suggestions?If you wish to replace the unit I now have, I shall return the original on upon receipt of the new one.Allen Morris

Such an important "addition" to our family.Just what we needed for our pool inflatables, for the kids' basket/volley/soccer balls, for inflatable mattresses and of course - for the car tires.Easy to use, so many options!!! It works very quick and it stops automatically.So happy with this purchase!
