Asani 12V Air Compressor - Portable & Compact Tire Pump, 150 PSI Heavy-Duty Double Cylinder Tire Inflator with LED Flashlight, Ideal for SUVs, Off-Road, Trailer, Truck, Bike, Air Bed

I was very impressed with the quality, functionality, and the usefulness of purchasing this to carry in my truck. I had recently had a flat tire when camping in a remote area, and used a manual bike pump to air up my tire, just to be able to drive to a flat hard surface, and change the tire. It was at that time I started thinking about buying a 12v portable air compressor. I did some shopping around, and I like this double cylinder design very well. I checked some of the retail stores also, and believe the Asani model I purchased was a much better choice. I did a test and lowered my size 16 truck tire to 10 lbs. I then timed how long it took to get back to 35lbs, and it was 3 minutes and 40 seconds. I think this was very fast, as I didn't have to hold it, as the hose screws on the valve stem. I love this feature. I also found I don't necessarily need the yellow coiled extension hose, however it is nice just in case it is needed. The portable compressor also works great on a farm for front tractor tires, atv tires, etc. Overall it is a very useful tool, and the bag it comes with is very nice too. I plan to store it in the rear of my truck cab at all times...

First impressions are good. The unit is bigger than I was expecting but that is not an issue. Built far better than the cheap plastic compressor that I am currently using. Works great. Adds 5 lbs to a 19" tire in 30 seconds. The noise level is also much lower that the cheap plastic unit. The default air hose screws onto the valve stem rather that just pushing on. The analog gauge would be a bit difficult to hit pin point accuracy but is good enough. The only caveat is the storage bag. More or less just a zip up cover that is to small to hold everything conveniently. Keep the accessories separate and it is good enough.

Overall, this air pump works for occasional use, but need more nozzle tips. The first time I used this pump was for blowing up pool toys. It worked decently for this application. The long hose came in useful when toping off and checking the air pressure in our trailer tires. The only issue that I faced was that instead of it having a cam style locking mechanism to hold the nozzle on the tire, it had a screw on end. This caused air to leak out when screwing the nozzle on and off the tire, but not a significant amount. The last time we used it we had just purchased large float tubes for a river trip. When we went to inflate them there was no larger end for this application. The larger holes for inflation are common on floatation devices such as inflatable kayaks, boats, and tubes. We had to manually blow up the tubes and also figured out a way to block the larger hole with our fingers and use the largest nozzle size the compressor came with. The process was time consuming and not very effective or efficient. To blow up four tubes took 1 1/2 hours. Overall the pump works as stated. We have not had need of the light yet, though it would be nice if it was dark outside. I definitely would like to see a few more nozzle sizes added for various common uses. The pump is pretty straight forward for use and the various ways to plug it into your car was a nice addition (lighter outlet/car battery terminal).

This has been great to own. I had to use multiple times before I purchased new tires & it worked great. I have peace of mind knowing I have it.

There are a lot of air compressors out there, but if your vehicle has a 12v battery, then you will always have a strong, twin cylinder compressor ready to inflate your tires.

My tires tend to lose pressure following the onset of the New England winter and sometimes it’s not safe or convenient to drive to a gas station to get the tires inflated. This portable pump delivers as advertised. I have used it twice since purchased, and it is lightweight, easy to plug-in and operate, and provides an accurate pressure reading as I confirmed with a pocket digital pressure meter that I keep in the car. It has a nice durable feel and appearance and the attached foldable handle makes it easy to move it around during and after usage. I got my tire pressure from 27.2 psi back to 31psi in no time at all and I’m very impressed with this addition to my set of equipment. The built-in light is also very bright and although I have not had to inflate my tires at night yet, I can see how valuable this feature will be if the need does arise (the fact that the light can be independently operated from the compressor makes it very promising for fixing stuff under the hood or looking for stuff at night). Once out of the box, the importance of the carry-bag cannot be overestimated (even though I actually felt bad about using such a very nice little bag for carrying the compressor). This is an excellent purchase and very good value for the money.

Well may, compact. Work great, I expected to work a little faster, but when the tire is almost full it moves slowly but works.

I used this pump 2x so far and it fills my dodge ram 2500 80lbs tires extremely fast from 60lbs to 80lbs in about 1 min, I was able to top off all 4 tires in less then 5min. Compared to the slim single piston pump I own that takes 20 minutes just to fill up 1 tire and the slim pump burnt out after 6 uses because your supposed to run it no longer then 10 or 15 minutes then let it rest for the same amount of time. If you do the math 4x 15 minutes run time is a 1 hour plus 4x 15 min rest time is another hour that 2 hours in total it takes to fill up 4 tires which is totally unacceptable, I also noticed that the analog pump gauge on this double piston pump is infact just about dead on with psi compared to the digital slim pump which was either under or over by 4lbs psi. I am so very happy with this pump and will never again buy a single piston pump. Infact If and when this double piston pump ever does fail I will order again from the same seller because the price I paid for it was just about $5 or $10 dollars more the what I paid for the slim single piston junk that I bought in Wal-Mart. This pump I bought off Amazon is built to last , it's durable and a hell of alot quicker. It also says to let it rest after 20 minutes of use but that is super fine because it does the entire job 4 tires 60 lbs to 80lbs in roughly 5 min. No need to run it for 20 minutes. I love this pump to death and recommend it highly.
