Tire Inflator Portable Air Compressor Pump| Precise Digital Gauge Display | 12V DC 100PSI 50L/min | Auto Shutoff | Dual Cylinder for car motorcycle basketball bicycle etc

I have owned both cheaper tire air pumps and one costing twice as much. I carefully considered all that Amazon sells. For a cheap unit, the AAA tire pump looks the most promising. However, the idea of "quieter and dual cylinder" had appeal. The Aokway dual cylinder air pump is much quieter and much faster than any single cylinder air pump that I have ever owned.. I filled three lawn front tires for my ZTR riding mower to 54 PSI and one wheelbarrow tire to 20 PSI within a quarter hour. There is no real benefit in filling four tires is less than that time.Pay attention to the instructions. Adjust the pressure on the digital display first. Wait until the flashing stops and the indicator shows zero. Be real sure you are on the PSI indicating scale. Connect the easy to use clamp style valve fitting.. Press the main pump motor rocker switch and the unit will rapidly fill the tire and stop at the pressure you have set. Works really well!The only difficulty is getting all the electrical wiring and the battery clamp adapter packed back into the storage compartment. I just put the adapter in a separate plastic bag to avoid aggravation.This is an exceptionally capable tire air pump at a very competitive price. I highly recommend it!

Broke it and a replacement, each after at first I really liked this, then probably a dozen uses later, the hose connection to the tire valve cracks or otherwise leaks, its just pure junk,...poorly compressed onto the hose....I wrote seller second time, no answer. Do yourself a favor and buy a different product elsewhere.

Will not run longer than 2 minutes in 50 degree weather, question if it would even run at all in summer temperatures. I purchased this as an emergency unit, and needed to use it 3 days after I could return it! Stay away from this, spend your money on something else.

This product works great. I use by put into car DC12V socket(cigarette lighter plug). The gauge is quite accurate but sometime the pressure is higher than digital display. I think the reason is the pump has double cylinder but I think that's ok because I like it (The pump has a high power). The power cord is long enough to reach all tires.

I bought this inflator for the wife. The plug-and-play features and the 10 years warranty made it very appealing to purchase.The first time I used it, I was very impressed. I inflated my tire from 23PSI to 31PSI within seconds and when it reached the desired tire pressure, the inflator shut off, a feature I really like.I used it the second time to inflate my wife's tire, the inflator won't shut off after reaching the desired tire pressure. I tried it on my tire and it did the same thing. It won't shut off.Seller should add a description on their product that the inflator is a "one-time use only"I am very disappointed. My $10 tire inflator lasted me more than 10 years.

Works great. Filled my 235x75 tire on my SUV from 15 lbs to 30 in 2 minutes 30 seconds. Added 5 lbs in 30 seconds. I also like the alligator clips to draw power directly from the battery in case the lighter outlet doesn't work.

I tried to pump up a flat tyre, but the tyre was not fixed properly and was still leaking so it over worked the pump. Pump stopped working after that on time.

pumped up a car tire additional 5lbs. in less than a minute and shut off at the set pressure. Neat.
