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

Easy to use, just set the tire pressure and let it run. Love it because I don’t have to keep checking pressure then continue to air up tires. Weather in Texas can fluctuate between 40 at night then 90 degrees during the day so if no nitrogen the air pressure can fluctuate. This is great to add or decrease tire pressure quickly and the adapter and battery terminal options are good and comes with attachments. I got the one with the extended cord, disappointed it’s plastic but works so I can reach all tires. No disappointment and it’s easy!

Very good product. I just wish it had a 110 plugin

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.

Excelente infla las llantas en segundos y cuando llega a la presión deseada se detiene

This unit is better than advertised. Filled my RV tires easily, automatic shutoff is great. Would highly recommend purchasing.

buen producto trabaja bien,me gusta.

I bought this item just to see how well it would work and let me tell you, it's amazing. Worked great on my Chevy Silverado and those big tires. I won't have to go to another broken air machine at the store anymore.

So far so good. I keep it in my car and have used it several times on a slow leak tire. I do wish it had a regular plug in so I didn't always have to snake it around to the cigarette lighter, but it does what it's supposed. I have not used it for anything but inflating car tires so I cannot speak to it's other uses.
