Lifeline AAA 300 PSI 12 Volt DC Air Compressor

As I said in the title, this does take some time to fully inflate but most likely you are just using this to top off your tires like I am. You use the controls to set the desired pressure, attach the hose to the tire and switch it on. It automatically inflates to the pressure you chose and seems to be pretty accurate. My TPM had done off and I used this to check and properly inflate all four tires. After a reset, the meter stayed off and I did not have to get out my large compressor to fix it. As my tires are usually within 1-2 psi of their needed range, this did not take long at all. I will definitely keep this in my trunk for emergencies and road trips. It also has a light in case you need to use this in the dark, which could be helpful especially on the side of the road.

AAA tire pressure inflator was very easy to use . It was easy to connect to all my cars and provided an acceptable level of noise while filling to 40 psi . Good build quality with regards to the housing. Rubber pads on the bottom provided good anti-vibration and kept it from moving around. I did notice a nominal amount of moisture exiting the the fill line but most compressors this size have the same problem. I would recommend this compressor for quick and routine weekly fill up. It will stay in my daily driver.

This review is for the AAA Digital Preset Air Inflator DC Power with Pressure Gauge Small, compact air pump. approx 8 in x 3 in x 7 in. the 10 foot power cord and the 1.5 foot air hose store neatly into the side of the unit when not in use. On the back it has the attachment for filling a ball/raft. Rubber feet to absorb the vibration when in use. The hose attachment is like a traditional foot pump, the nozzle is that style, locking on the valve. FYI- The power comes from a standard cigarette lighter, so make sure your car has one w/15 amp fuse or greater. There is NO battery to charge, all power comes from YOUR cigarette lighter plug. The gauge is digital and all you do is preset the pressure you want and the pump fills it to that level, no need to sit there and watch it. Very cool for those that are not mechanical. There is a light on the side of the unit to light up your workspace, there is no on/off switch for it. For its size, its a pretty fast little pump, perfect for smaller jobs or road side emergencies, it takes 6 minutes to fill a tire from flat. Don't expect this to fill your tires in the same time as a full size air pump, its a small unit. Perfect to fit in your car. Great item to put in your GF/wives car... I would recommend this pump. Understand, I have only used this ONE time to fill my tires and it worked great. I just hope that this unit will last for years.

The AAA ~ Mini Air DC Power Compressor with Pressure gauge Can be used for many different things, not just to air up a low Vehicle tire, for example it can air up, An air mattress (Twin to Queen) when camping, bike tires when hauling bike Over the road to remote locations, Swimming pool Floatation toys, most (small to med) items ~ that can come within 8 feet or your vehicle. The cord that goes from the DC charge port ~ to the compressor unit is about ten feet. The air hose that runs from the compressor to your tire, is 18 inches long. The total dimensions are 9" long x 6" wide x 4" deep. These dimensions make it ideal for easy storage in most vehicles. The issue, that I noticed, was using the unit in excess of 15 minutes, Most of the time with a 300 PSI, DC Compressor, any use (on time) over 10 min is not recommended, The smaller unit can "overheat" and the internal components will "short out" I would recommend, Not using this device if you think you will need to exceed 10 min of use, and if you do, Turn the unit off and wait till it cools, before plugging back in (to your in car, charge port), to continue to inflate your items. ~ Try and always make sure the vehicle is running when using the (DC) charge port on your vehicle, This will ensure Proper voltage is going to your unit. When inflating a tire, as this is, not a standard compressor, It will take around 5 minutes to inflate from 20 PSI to 44 PSI. This to me, is more of an emergency compressor Not for standard daily use. If you have a Slow leak, please consider taking your tire in for repair at a local (tire shop) But be sure to air the tire up, using this device before you go. *Will not blow out sprinkler systems. *will not inflate large swimming pools, It will inflate, Bike tires, Slow leak Car tires, Pool accessories (small to medium), Queen Size and under air mattresses. Or any other small to medium Inflatable.

I got this 12V compressor to add to my "go bag" that I carry which has a couple tire gauges, self vulcanizing tire plug kit, breaker bar, foot pump, and a couple other items. One big thing that is missing from the item description, even in the documentation, is the power cable length and hose length. The power cable is 10' and the hose is 20". So, be sure that it will reach your tires. For me it was a little bit of a disappointment because I'd hoped to be able to use it if needing to air up my boat trailer tires in an emergency but it would not reach the left side tires which are furthest from the 12V plug on the helm. I use an air compressor for normal airing up around the house so this unit would be very limited use for me. To test it out, I used it on my F-150 to air up a tire that was a couple of pounds lower than the rest. It was the left rear and I had to use the rear console 12V plug to reach the tire easily (supercrew). I was surprised that the gauge on the unit seemed to be pretty accurate and read the same 31 lbs as my tire gauge. The gauge goes to 300 lbs so the resolution isn't great but is acceptable for getting a tire aired up very close or a little over where you need it, and then checking with a gauge and airing down to correct pressure. Adding a couple lbs of air only took about 30 seconds, and that was on a 285/55R20 all terrain tire. I did have to do it twice because the new connector was pretty hard to pull off the valve stem when done so I lost some air. The second time I knew what to expect so I unlocked it and then quickly yanked it off with some force. The unit takes up very little space. The hose, power cord, and accessory kit tuck into a storage space on the side and stay tucked in. The documentation says it will pull up to 10A so make sure your 12V outlet will supply that by checking the fuse or labeling. I assume that 10A is the max that would come in closer to its max pressure and that normal lower pressure stuff wouldn't pull that much current. Also, a cool down period is needed after 15 minutes of continuous running which in most situations you'd probably never see. All in all, not a bad little unit.
