    After some success with the battery (doesnt last long), the 12 VDC charger did not work.

    Like many newer cars, ours lacks a spare tire and, instead, includes only a 12v compressor. Sadly, the tires are always losing air no matter how many times we take it in for repair So, the included compressor gets used — and cursed at for its flaws. This battery operated compressor is a huge improvement. Most importantly, I don’t have to fool around with wires and cigarette lighter sockets (unless I use the included 12v adapter instead of the battery). Next, it’s automatic. I can set it for a precise pressure, start it and go sit in the car until it stops. There are several presets, plus it uses the most recent setting if different. All four tires come out exactly the same without any fooling around. My tpms reads two psi lower than the compressor setting and I don’t know yet which is correct, but I’ll figure it out. It charges and pumps slower than I hoped (but not slower than any other 12v compressor I have used), but the time saved by not having to adjust the pressure or stand outside monitoring it more than compensates. The screen is easy to read and the settings are simple and obvious. There is always room for improvement and this compressor is no different. I would like to see a compact case or sack to protect it. I also would like it if the accessory connectors could be secured by clipping onto or screwing into the casing. (It looks like something like that was contemplated but not actually accomplished. There is a place to clip the hose. There are a few other fittings but they aren’t really secure.) The 20v battery looks remarkably like a Dewalt, but sadly it is not identical, so I cannot substitute batteries/chargers I already have. No doubt there are legal reasons for this. The battery, however, is lithium and will receive such light use that it should outlast the car. If the battery eventually fails, there is always the 12v adapter.

    I live in a city where all of the gas station air pumps are always broken, and when they arent its a line to use them. And thats after driving to the gas station in the first place. Having this pump is 100xs more convenient. I keep it in my trunk with the power adapter. When the weather changes cold/hot and my tires lose pressure in back up and going in about 10 minutes. Less time than driving to a pump! Its a great quality pump, and similar priced to the big tool brands (the ones that dont include batteries) but comes with a lot of accessories! Well worth having on hand!

    So far this has worked great. I havent had any flat tires on my car but I have used it to inflate a few bike tires and its working great for that. I have this along with my emergency kit and jump starter in the back of my truck. I may never need it but its nice to have just in case.

    This is awesome for the average homeowner who needs to inflate bicycle tires and occasionally inflate a car tire. Dont know about you, but every time I go to the gas station to fill my tire (after the tpms light comes on), the air compressor either costs money, is broken, or there is a long line. Hah! No more of that. Just attach this unit to your tire and the led shows you the current tire pressure. Enter in the pressure you want and click the trigger and it inflates the tire to that pressure and automatically shuts off. I checked pressure with a second tire gauge afterwards and it was spot on. So easy that I am looking for other tires to fill! In my opinion, this would make a great housewarming gift for someone to add to their tool collection.

    This tire inflator works great - and for a multitude of things! We have in our camper, should we need it traveling - but it’s also super helpful for pools, balls, etc. So happy we came across this!

    This works great on my car and my daughters bicycle tires as well, Didnt take that long to come up to pressure on all 4 tires. Works quiet and does a good job. I would recommend to anyone looking for a small portable compressor.

    This little dynamo is a life saver when you find yourself with a flat tire. It has come in handy several times for me so far. I have a slow leak in one of my tires and I have come outside to a tire that was down to 15 PSI. Too low to try to attempt to drive on it, even slowly and no other way to put air in. I can air the tire up from a low of 5 PSI to 36PSI one time on a single charge. A complete lifesaver when in need. Even though the tool looks cheaply made. It has some weight to it and is built from quality material. It is quieter than I had thought it would have been. It’s not a fast process when airing up a tire but it does get the job done. I did find It to be approximately 2 PSI off from what it says it’s at and what my tire pressure gauge says it is.

    This unit is very large. I didn’t expect it to be as big as I thought, it’s as big as a handheld drill. It is rechargeable, and it comes with a battery pack. It’s powerful though, and does the job.

    I’m impressed with this. I’ve been using it on a tire that has a very slow leak, that I just haven’t had the time to get fixed. The operation is very easy, although the icons for the modes are small and difficult to see if you have 40+ year old eyes. It inflates pretty quickly and isn’t overly loud. I have other tire inflators that will over inflate by .5 psi to account for when you take the inflator off. This doesn’t do that, so just program it for .5 over your target before you start pumping. I like it and will keep it in the Jeep when we hit the road.
