Tire Inflator Portable Air Compressor for Car, 12V DC Tire Pump 130PSI Dual Cylinder Tire Air Pump, Heavy Duty Tire Inflator with Digital Pressure Gauge & LED Light,Auto-Off Function

Very nice. Operates great. The cord could stand to be a couple feet longer. I have a ford f150 pickup and it barely makes it to the back wheels. But very powerful and airs up very fast. Stops on the desired pounds. Easily set. quiet.

Does what it’s supposed to do I recommend it for having this compressor in your car. It shuts off at desired psi really useful filled my tire from 20 psi to 35 psi in about 1 minute not bad. The accessories I haven’t had a use for them but they’ll be used some day thats for sure. Im not sure how well you can expect it to air up big tires like for SUVs but it should work very well on passenger cars. It does get hot quickly although mine didn’t as im not airing up 4 tires from a low psi but it did get warm not alot but warm. My only complaint is the bag it’s not really well made the zipper busted trying to close it but the bag issue should be a factor in deciding not to buy this compressor. You can easily just buy a 10-15 dollar tool bag that’ll be more use fool for storing everything you need like tire plugs air hose etc. overall im happy with my purchase will buy another one for my other car and also before I forget my hand gauge from napa reads 36 and the compressor reads 35. If your a person that likes to have exact pressure all the way around then maybe doing 1 psi under what you normally fill. Not sure if everyone has this same to report 1 psi difference

After three 3 months of use I find out this inflator is quick to air the flat tire, and it works well. However, the gauge reading is not accurate ( it's about 10% smaller than the actual value). I set up 35 psi and after the work I use another calibrated barometer to check the actual air pressure is about 38 psi.

I watched a YouTube video about this compressor prior to purchasing it and someone commented that they wanted someone to confirm it had two cylinders instead of one being fake. I opened it up (see pictures) and confirmed it has two cylinders. I can definitely notice an air volume difference compared to a single cylinder air compressor I have. I also did a test, I took all of the air out of my car tire and filled it with my single cylinder air compressor. It took roughly 3 minutes and 39 seconds, I did the same test with this double cylinder air pump, it was able to inflate the tire in about 2 minutes and 36 seconds. So not half the time but it was faster. I do want to mention that my car is a 2020 Toyota Corolla with low profile tires. If these were normal car tires or large truck tires, I’m sure the time difference would be much greater. I want to point out that each test I went from 0 psi to 30 psi. Also, I measured the inrush current (inrush current is a surge of amperage when an electric motor is first turned on since no electro-magnetic field has been established yet, the amperage is briefly higher than normal for a fraction of a second) with a clamp ammeter and when the motor first turns on it pulls between 12 to 14 amps (but just for a fraction of a second, I did not record the normal running amps). However, I observed that my car cigarette lighter fuse was only rated for 7.5 Amps. I did the tests while the car was running and I use the cigarette lighter plug located inside the cabin area and I have not (yet) blown the cigarette lighter fuse but I did order some extra 7.5 amp fuses just to be safe. One very minor thing I noticed is that when I preset the pressure to 30 psi, after the pump shut off, and I waited several seconds, the pressure dropped to 29 psi.. I just turned the compressor back on briefly to get that extra 1 psi. This may not be the compressors fault, it may be because the air is cooling off and shrinking back down, the airline leaving the compressor definitely gets hot. I would say this compressor is excellent and highly recommend. I’m often helping others out of a jam with these 12 volt air compressors! I have also used it with a 12 volt cigarette lighter extension (I think it was 10 feet long) and it has worked great, I would recommend the extension if you have a large SUV and need the extra length. Many years ago, I waited over two hours for AAA and that was not fun. This compressor will get you on the road quickly. Most tire punctures leak slowly so if you fill the tire up you can usually drive on it for awhile and top off now and then or get home or to a repair shop, much better than being stranded. I once blew out the side wall on a tire while on a road trip, I put the spare on and the spare was flat, I used a 12 volt compressor to fill it, I was on the road in a short time. This was on the interstate in the breakdown lane, no safe way to get off the road. If I did not have a 12 volt compressor we could have been there for hours… very close to tractor trailer trucks going by at 80 mph just feet from the car. I had many family members in the car with me, so it was critical, and potentially life-saving.. These compressors are also very convenient when you have to adjust your tire pressure every season due to the temperature changes. After a steady read of 30 psi from this compressor, I disconnected it and used a separate digital tire pressure gauge, it also read 30 psi. So, overall, I’m very happy with it!! Little note, I like to keep multiple 12 volt air compressors in my car in case I need to loan one out to a family member/friend/coworker etc, if they have a slow leak and need to top off a few times a day until they can get their tire fixed. (Maybe I just like to be as prepared as I can be). This compressor will likely pay for itself the first time you use. Have a good one :)

Solid little unit, sturdy and well built. Nice thick rubber “feet” to keep it stable on the ground. I didn’t have an issue with the meter like some reviewers mentioned. I checked it against a manual pressure reader that I know is accurate and they matched. Don’t worry about the adapter plug…the receiving end is heavy duty and not some dinky thing that will break. I will definitely use the adaptor and battery cables rather than plug into the lighter. Instructions even suggest to use it this way for best result and more power. You have to have your car running so as not to drain your battery.I was also worried about the connector to the tire valve, and to my relief it is metal, not plastic. The hose is heavy duty and about 2 ft long. The extra adaptors are also of surprising good quality.I didn’t end up actually needing to put air in my tires to smooth out the ride like I thought, I needed to take air out from highway driving in a heatwave. But I feel very good about having this compressor for winter when I have to tweak the pressure every so often, and have no doubt this compressor can handle filling tires up completely. I have a car not a truck or SUV, and this is plenty for my needs. For the specs, it was also the best deal. I am pleasantly surprised by the quality of the unit and am glad I bought it. No more running around trying to find air at a gas station.The only suggestion for improvement would be to make the storage bag bigger so it’s easier to take the unit out and put back in. There is also no room in the bag for the coil hose and the battery cable adaptors. I had to save the plastic bag from inside the packaging to put those in. Overall, highly recommended for moderate use.
