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

I loved this portable air pump from EP Auto. It's compact, lightweight, and works super well. It inflates tires quickly and effortlessly, making it ideal for carrying in the car for any emergency. The cable is a good length, and the digital display makes it easy to see the exact pressure. It also automatically shuts off when it reaches the level you set, which is very practical. I've used it several times and it hasn't failed me. Excellent product, highly recommended. 🚗💨

This is my second purchase. I bought my first one of these 5 years ago and it has been a great purchase. It has saved my bacon at least twice, when a tire had a slow leak (and one time a rather fast leak) and I was not anywhere near somewhere with air. Also I can check my tire pressure and top them off at my own home instead of waiting in line at the gas station in terrible winter weather etc. At the price listed, I only have to use it 3 times a year to make up for not paying $2 a fill at a gast station: i have easily used it that much. My first one is still working perfectly after 5 years, but now my teen is starting to drive, so I bought a second one so there will be one in each car, and I can teach my kid how to use it. Great product, easy to use, reliable results 10/10.

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.

For the price this thing isnt bad at all. Better than most and handles up to 60psi in my testing. It works way better than I expected for the price. Even though the listing says it cant be used for trucks, i used it no problem multiple times on my half ton pickup. However, it heats up a lot with one tire so I would not recommend this if you need to use it for multiple tires above 40psi. You probably wont need to anyway, bit it is convenient to have something to make sure your tires are properly inflated for road trips. I didnt give it a break bumping 4 tires to 65 psi on my camper. Yes, its not meant for that but i wanted see how far i could push this little guy. I should have probably gave it a rest after the 3rd tire because it was literally ready to cook an egg lol. I figured though id give it a go on the last tire, and that's when it have up the ghost. It was almost to 60 psi when some seal broke. Tomy surprise the little thing kept pumping air but the littlw tank was now leaking air from probably a crack in the tank behind the plastic front cover. I was impressed by its performance. So basically it CAN make it to 60psi. This would be fine for any tire up to 40psi, it should handle it well but make sure you give it time to cool down because it's not meant fir heavy duty use. Still for the price its not bad and it was tougher and more realization than some of the other cheap ones ive bought in the past. Id recommend this if you have a car. It is small light and not just a plastic piece of junk like most of them are.

Works amazing, fills up tire really fast and much better than the battery powered ones. I had to replace my old 100 dollar tire inflator because it cold barely fill up one tire but with this I filled 4 in under 30 minutes

Nice little pump works well set it and it does the job

This is the 2nd portable air compressor pump. The first one was a gift for my son’s car (it too was an EPAuto 12V DC Portable Air Compressor Pump). I highly recommend this product because compared to the smaller battery operated ones, you can never be sure that it will inflate all 4 tires on a single charge. This one came in handy especially after the snow/ice storm of 2026 where I had to inflate tires on both of my cars, because of loss of tire pressure due to the cold. You can’t beat the price, portability, and reliability of this product. It’s so easy to use. Just plug it to your car’s cigarette lighter, make sure the compressor is switched to the OFF position, connect the air hose to the tire stem, set the desired PSI on the digital display (I always set mine for .5 over the desired PSI), then turn the machine ON. Then wait for the compressor to do its job. That’s it!

Easy to use, and speedily topped off my tires to 39 PSI. Quieter than expected. Light came in handy as I filled my tires in the dark.
