AstroAI Portable 160 PSI DC Heavy Duty Tire Inflator Pump Auto Shutoff with Screen, Dual Cylinders & Dual Motors, 12V Air Compressor for SUVs, RVs, ORVs, Cars, Air Mattresses, etc. Yellow(NO AC)

I bought this for my detailing keg, it goes to 100 psi in about 8, 9 minutes, bearly gets warm, outside in the sun, and it stops automatically at the set PSI, I don't have to guard it. easy to use, didn't have to read the instructions. It feels like a good quality build, you can power it from the house outlet or from the car , it has a switch between those.

Correction on this review. When attaching to the cigarette lighter in the car with the length of wire on the product works good. I added an 9 foot extension and that made a voltage draw drop. Not allowing it to get enough compression. If you’re going to add a 9’ exit extension to this product it works fantastic when attaching to the car battery. It was almost more efficient that way. Outstanding product you can’t go wrong. I would definitely order again if needed one.

I had just purchased a new F250 Ford and needed to add air to the tires when I found out that my old cigarette lighter tire pump just wasn't going to do the job. I purchased this pump to handle the higher pressures (~60-65 PSI). This pump utilizes two methods for power; cigarette lighter for lower pressure tires (ex. normal car tires) and a direct clamp connection to the battery for higher pressure tires like I have (above about 40 PSI +/-). This pump does fill the tires much more rapidly compared to my older pump and has sufficiently long leads to connect to the battery and the hose to the tire. I was able, on my truck, to connect this pump to the battery and to reach the rear tires without a problem. I have taken one star off of the review due to the spiral coiled air hose. While this hose will reach the tire when the power cord is at full extension, the problem is that the spiral tries to retract on itself and will pull over the pump or pull against its connection to the tire. It is workable but requires you to be creative in positioning the pump so it will not tip. This pump was able to fill all four of my tires to 60 or 65 PSI (from 50 PSI) in about 10 minutes. The gauge seems to be close although I get about a 4 PSI difference against a pocket tire gauge. Auto shut off works very well. It is a large pump that comes with a storage bag and requires a larger space to store in your vehicle. It will not fit in a center console or under seats.

First one I got was used because the bag had sand in it. Amazon sent a brand new one out and all is well. My GMC 3500 requires 80 psi and this pump handles it well. Shuts down when selected pressure achieved. GREAT PUMP! Recommend connecting to the battery over the cigarette lighter use. Gets pretty hot when plugged into lighter for my application.

Easy to use and works great. I use it almost daily because the rim needs repaired. Until then, we air up the tire daily using this. Only takes a few minutes going from flat to 35 psi. I bought this about 6 months ago or so. High quality.

UPDATE:The vendor contacted me via email and worked with me to make it right. I returned the original unit and they sent me a replacement that works exactly as described.I like this pump a lot. It:- is reasonably priced- comes with a nice set of accessories- pumps air MUCH faster than my old pump. It brought my pickup's tire from 73 PSI to 81 PSI in less than 3 minutes. my old pump took 12-15 minutes to do that.- customer service was responsive and quickly sent me a replacement without hassle - excellent! They contacted me, probably responding to the review I left. Most companies occasionally put out a unit with problems. The important things are that (1) the "duds" are not frequent, and (2) customer service quickly and competently handles any problems encountered. I can't speak to the frequency issue, but in my opinion their customer service was first rate.My only complaint, and it's a minor one - a quibble really - is that the electric cord is a bit short for my needs. Fortunately, I happen to have a 15 foot auto cigarette lighter extension cord, so I can connect the pump to my truck's battery under the hood and easily reach the tires on my 5th wheel trailer. I always connect to the battery with the relatively higher tire pressures I have to maintain.I am very happy with this purchase and can recommend it to others in good conscience.=================================================================I just got this pump and it increased pressure in my truck tire from 74 psi to 81 psi in about 3 minutes - great! Except right after that I connected it to another tire, it pumped for about about 3 seconds and just stopped. Now it does this again and again - it just runs for a few seconds and stops. Yes I'm using it connected directly to the truck battery with the truck engine running. The set point on the pump is at least 5 psi above the current pressure. It just does not work anymore - very disappointing - it's going back.

Great pump. Used it the day I got it on my truck and bicycle (with the small air intake). The digital setting worked great. Only down side is the handle doesn't collapse so it is a little bulky. I keep it under my seat in my truck so not much space. For a car with a trunk it is easy.
