epauto 12V DC Portable Air Compressor Pump, Digital Tire Inflator

This portable air compressor works exactly as expected. It inflates tires quickly, is easy to use, and the compact size makes it perfect to keep in the car for emergencies. The power cord is long enough to reach all four tires, and the pressure gauge is clear and accurate. Great value for the price. Highly recommended!

Quick review for a product that vastly exceeded expectations. This was my 3rd replacement for cheap tire inflators that failed just a few uses. I had a set of rims that never sealed properly despite being checked and serviced on multiple occasions by different shops, even with new tires mounted. Every wheel would eventually develop a slow leak and I was using an inflator enough to be embarrassed about it. The 3 inflators prior to this purchase failed in just a few uses each. Whether it was the compressor, power cable, or some other electrical issue, nothing around the $20-30 price was going survived what I would even call light use. (Shoutout to Slime products for being some of the most unreliable hardware/junk I've ever used!) I was getting rid of the car and its awful rims, so I really didn't want to spend much on quality. This was my last try before the nuclear option of dropping $100+ on some sort of battery charger/tire inflator combo or behemoth from Milwaukee that I would never use. So I did some very light research and after seeing a few decent reviews, settled on this thing for the same price, 2 years ago. Since then, this solid little unit has done everything I've ever asked of it, and I've asked a lot. It has never failed to air up even a full set of 4 perfectly average, 17" 225/50 tires, from fully flat to overinflated (slow leaks!). Even after pumping up a full set of tires from low pressures, I don't think I ever triggered the overheat protection of the unit. The digital pressure gauge and cutoff feature of the unit are pretty accurate when checked with a manual gauge; I never underinflated a tire in relation to my desired PSI. It's not fast. I don't think you can get --or should want-- fast at this price point, but it is reliable. EPAuto says not to use it on truck tires; I think you probably could if you had to, but singles only, with lots of breaks. They don't seem to have wasted much money on crappy cases that conceal tiny compressors like others at this range, so it doesn't look cool. Oh well, never going to impress anybody airing tires anyway. It has a spotlight, which has come in handy more often than I expected. My biggest knock against the EPAuto is the screw-on valve connector, which can be a pain to use. I always felt like I was losing a pound or two of air while scrambling to disconnect hose quickly, but protip: a little brass schrader quick-connect chuck for $5-10 her on Amazon and that problem is solved. (Or overinflate by a pound or two and stop whining) It comes in a decent little soft carrying case, and it has storage slots for coiling the power cord and air hose. It's crazy, but it almost seems like they cared about how this product might actually be used more than once. It would make a nice little emergency tool for the trunk, even if you own more expensive compressors. I rarely give reviews, but good products at inexpensive prices deserve it.

This air compressor works really well and is easy to use. It inflates tires quickly and the size is perfect for keeping in the car for emergencies. The build quality feels strong and the power cord is long enough to reach all tires easily. Good value for the price and very convenient for road trips and daily use

This is a short term review as I have used this pump only once. I like it. I have another brand, a few generations older model, and comparing this new one to the older one is like night and day. I was very surprised by the amount of noise it produces. Whereas the older model/brand was extremely loud (can probably be heard for a few hundred feet), this one is very quite. Very impressive. All my neighbors knew when I was airing up my tires when I used the older pump. But, not now. I had to actually listen carefully to try and hear it running as I was walking around the car to check on it. Very nice. Some people said that they had issues with the preset pressure overfilling the tire and the nozzle causing lots of pressure to escape during connecting/disconnecting it. I found none of these to be an issue. The pressure was fairly accurate and the nozzle, if removing it is done swiftly, did not cause any significant loss of pressure. The gauge on the pump is fairly accurate as I have tested against two quality dial type pressure gauges. One of them being a Snap-On brand gauge. The pump comes with a nice little vinyl bag in which to store it. I like that. Granted, this pump is rather industrial looking when compared to other brands. It is not as ergonomically designed or housed in a nice shell, but, it does a good job. Ninety nine percent of the time, I go for go, not show. I gave this pump four stars because I thought that the light should have its own on/off switch. I realize that the lights are LED type, and probably do not draw much power, but, it still would be nice to be able to turn them off, just in case the vehicle's battery is not in top shape and you are stranded on the side of the road. You surely do not want to have to get a battery jump start after the tire issue is fixed. Overall, this is a good pump. I highly recommend it. It is easy to use. Quite. Compact. And, works well. Thumbs up!

Terrific, small air compressor. I bought one for my pickup and it worked so well, I picked up a second one for my Bride. The cord plugs easily connect to a power outlet (aka cigarette lighter) and is plenty long to get to all tires. Auto shut-off when it reaches your choice air pressure. Cute, too...they look like little red choo-choo trains. They come with their own storage bag.

Update on 3/8/2017 - Still working like a charm! Inflates quickly, quietly, and accurately. I highly recommend - It's small, powerful, and I'm confident that it will get me out of a jam when I need a small, portable compressor. It's already saved me a lot of grief a couple of times, when I find a tire almost on its rim and I need to get air in in it to make the vehicle roadworthy. No regrets on this purchase at all! Update on 2/7/2017 - Received a replacement pump, and it works like a champ! VERY Pleased. As a matter of fact, I was so pleased, I ordered another so I could have one in each of the two cars. It inflates quickly and quietly. It's compact, and seems to be rather durable. Original post: I bought this "EPAuto 12V 120W Portable Air Compressor Pump, Digital Tire Inflator by 100 PS" from Amazon as an Amazon Prime customer yesterday, and it was delivered today. Yay! I opened the box, and was rather excited to find it had some weight to it (not a lot), It but didn't seem flimsy or cheap in any way. I thought that if I were to drop it (or even toss it, and the recipient of the toss missed it, it would survive being dropped). It's a rather solid feeling unit, and seemed to be built much better and more durable than other pumps I've owned. Now, the test - I took it outside, plugged it in to the cigarette lighter socket of the car (making sure the power switch was set to the off position first), started the engine of the car, and saw that the display on the pump illuminated. I screwed the fitting for the fill hose onto the tire valve, and it told me the tire pressure was at 14.5 psi. I thought (and hoped) this compressor would remedy that issue, until I adjusted the desired pressure with the bottons to 35psi, turned on the power switch to on, and NOTHING happened. I turned the unit off, unplugged the unit (and the display on the unit went black) from the power source (cigarette lighter plug), checked the power cord in-line fuse, and the fuse looked fine. I plugged the unit back into the power source (cigarette lighter plug), the display lit back up, Yay! Powered up the pump again (turned the power switch back on),and NOTHING happened (again). No click, no noise at all. It was like the power switch was an ornament and not a functional piece of the unit. Right now, as I write this, it's back in it's in box with its accessories and packing materials being returned to Amazon, scheduled to be picked up tomorrow. I will order another one of these units to give this product another fair chance (as I would any restaurant or other merchant (Hey, everyone is entitled to an "off-day"), but so far, I'm very disappointed with the fact that this unit is a "#1 Best Seller" in the Amazon rating system, yet the quality control system for product is so <substitute the expletive of your choice here>. Did they test this item, spot check some, or what?!?!? OR, maybe just pushed ot out the door, resting on its laurels? Other recent reviews of this "EPAuto 12V 120W Portable Air Compressor Pump, Digital Tire Inflator by 100 PS" show similar experiences to mine. In the future, I'll pay more close attention to recent dates of the reviews. I will update this review when I receive the replacement unit I'm ordereing, and talk more about it when the time is right. I'd like to see t work, and last a while... Thank you for your time for reading this review, and I apologize if you find this review a bit "long-winded" (it IS for a compressor, after all, and I'm letting my compression out... :-) . Sincerely, Jim

This is my third one. The first two were for two separate vehicles. One was stepped on in the front passenger floorboard and the cable got torn, my fault entirely. I have used them many times, great little units, dependable workhorses. I will use the storage bag it came with to keep it safe in my car. I have one issue: this third unit arrived as an open box item, very disappointing as I purchased a new item. It was not an Amazon Warehouse order. Somehow I'm going to have to test it out, difficult with items like this that are only used when needed, and someone returned this one for some reason. This is the second open box item I have received when purchasing new in the last six weeks! Amazon, what are you thinking? I did order something from Amazon Warehouse a couple of weeks back, a wagon, which of course arrived open box but I paid a discounted price. I am not against open box, only when ordering new do i take issue with receiving used.

Worked great! I really like being able tonset the psi and have the compressor fill to that number! I only wish the power cord was a tad bit longer. Highly recommend!

I bought this as safety precaution, and recently used it to pump up some soccer balls. It seems easy to use and has enough power for normal inflating jobs. Kind of hard determining the exact number of PSI to use for each thing you inflate, but otherwise a good tool to have around.

Never got the item. Do not purchase.

Fills up car tires from 0 to 32 psi in 7-8 minutes. Does not gets hot as other brands. The only thing getting hot was that air flow pipe.

I bought this for occasional tire maintenance. Thus far is has worked flawlessly. Once every week or so, I'll plug it in and air up the tires as needed, usually only a few psi needed. When I'm checking oil, coolant etc. this little compressor has become part of that process and I find it very useful. I have used it on two different cars and one full-size SUV. The instructions say it's not designed for use on bigger SUV's (and probably pickup trucks) but if you're only going from 32 up 35 psi, it works just fine. I would be cautious airing up a big tire that was quite low, this unit would likely melt. It was discount by about $12.00 when I purchased it, so the price point was very good. Keep in mind that it's a small unit and it won't last forever, but I highly recommend getting one.
