AstroAIPortable 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 usually wait to review products and give it a little time. This unit has held up and works better with the car on. i love the battery clips, and its pretty fast. The bag is a nice touch and the battery clips make it easy. It matches my psi in the car so I feel like its pretty accurate. I recommend

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.

Well it works well its been almost 2 month maybe more I do roadside its a good commercial one butttt———> the plug that used in the cigarette charger is to big and it got stuck so every time I used it I plug it on my battery while my car is on

No regrets in buying this, very fast and easy to use, only one problem, and I have found the same thing on all the inflators I have owned, when it it shuts off at the psi you have it set to, if you check with a pressure gauge it is off by about 2 to 3 pounds, but like i said, every inflator i have had was the same, so to counteract it, i just set it 2 or 3 pounds higher.

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.

Extremely satisfied with my purchase. Product arrived on time, works like new, everything was there. Very easy to use, no leakage, great preassure, refilled all tires to correct preassure in under 5 mins. Impressive for mine being big tires

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.

Can't speak for others, but it worked properly only one time. And it burned out 3 of my car DC plugs. I also tried using this on a generator DC plug and it acted REALLY weird on that. I had bought this to fill my SUV tires as it was rated well enough to do that.What I did like about it is that it did not generate heat like the old one I replaced it with. The one time it did work properly, it filled the tire quickly from nearly flat. It's also fairly light and I like the handle for ease of carrying.Since I have a Jackery, I will probably replace this with an AC version. Certainly something more heavy duty.UPDATE: AstroAI with no prompting from me, contacted me and sent me a new one. Such customer service is rare. I had not asked for a replacement. They have not asked for the old one back, but I am prepared to do so if they want.I received the replacement in about 4 days, also a pleasant surprise.I failed to mention one of the other things I liked about it, which is the auto-shutoff when it reaches the PSI you set it for. Saves constantly checking it every few minutes to see if it's over-inflating.My personal opinion is that if you're going to be inflating tires over 35 PSI, you buy their more expensive one that includes an AC plug. I don't know this, and others may not have mentioned it, but I suspect the power draw for higher than 35 PSI might be too much for the DC outlets if you're inflating from nearly flat. Since flats rarely conveniently happen at home I also recommend a solar battery with an AC outlet. Personal opinion.
