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

I rate this as a great product. It works just as described. Once you have everything hooked up correctly (important – turn your vehicle on per the included instructions), the device display will show how much air is in the item you are trying to inflate. Then use the + and – buttons on the monitor to set the desired pressure. Turn the device power on and watch the monitor as the device inflates the item to the desired pressure and once that pressure is reached, it cuts off automatically. Couldn’t be easier to use.

I have one of these in each vehicle. It’s easy to use and when you need it, it’s right there ready to go. I will never pay for air for a tire on a road trip ever again. The only disadvantage is that the cord is a bit on the short side. It was able reach the rear tire on our gmc acadia but just barely. We bought a 9 volt extension cord and problem solved on my chevy colorado truck.

The first thing that i noticed was the air hose connector, it screwed on (other compressors either had a lever that you flipped with great difficulty, or you had to hold it until the tire was filled. The second thing that i love the most is the automatic shut off when the tire reaches the set pressure. Finally, i think it fills up the tire fairly quickly compared to other compressors i’ve used. I just thought of another positive feature, the ability to choose a color for the compressor housing (i chose yellow so it could be seen at night by other drivers).

This is my second time purchasing this same item because it is it works really well i have no complaints it functions great don’t need to charge you just need to plug it up to your cigarette plug thing ..i 100% recommend and i bought a second was because my dog messed up the wire for the first one lol everyone should have air compression in their car and has a light for any issues that you have to look at in your car …it’s a real lifesaver when you don’t wanna go to the gas station to fill up your tires

I thought the price was fair and was happy it worked so well. I used it a few times shortly after purchase to inflate a tire which has a slow leak. After my car sat flat for a few days my rear passenger tire would be completely flat. Took about 10 minutes to fill up the tire each time. Definitely work the money!!

Tire was flat after leaving work borrowed a coworkers and then i ordered this at 6am, it was delivered by 10am! Thank you amazon for being a lifesaver! Built in led light and digital reading makes for easy use. Flashlight great for night time air checks!

I have a slow leak in one of my car tires and wanted this just in case it went flat. It works beautifully and does reach all my tires. The overall cord could be longer but, again, i was able to reach all my tires.

I do recommend this product.

I used this product for the first time forgetting its not for truck tires (my bad). I pumped 2 front lt tires from 40psi to 51 psi on a 1991 f250 with a 460. Did the job pretty good just read that it’s not for those tires though so don’t do what i did. Will be used on my 1986 thunderbird èlan for winter.

I bought this for the purpose of refilling my car tires when they get low on air. I prioritized quietness (within my budget) when i selected this product, and i am very pleased. I mean, it’s still an air compressor, and those are just going to be loud, but this one is tolerable and not ear-splitting.

Aside from the noise aspect, i found this air compressor very easy to use. The instructions it came with were very clear, and operation was very simple. It took a reasonable amount of time to fill the tires. It does get a bit hot, and there’s a nice big obvious warning sticker on the unit saying so.

I also like the aesthetics. It’s a pretty blue, and it looks like a train. It’s very cute.

My only complaint about it is i wish i could plug it into the wall. I bought it knowing it’s meant to be a portable, on-the-road air compressor and only plugs into the car’s outlet – the noise level was more important to me – but i still wish i could power it from a wall outlet. No star deductions for this because the product page made it very clear.

I only really need this for those random situations… Like blowing up my mower tires or bike tire. But for the few times i have used it in the last month it has worked well.

It is also pretty quick compared to my last one.

I will say that the cord is not long enough to get out of my truck down to the floor easily. But most are like this. So i bought a cord extension to compensate.

Also, that built-in light is pretty dumb. More specifically that i can not turn it off. I have not yet had any need for it. And all it does is shine at me when settings things up. I get it would be useful if i needed to blow up tires at night on the side of the road or something, but this thing lives in my garage.

Would recommend.

I bought this to keep my tires at the appropriate pressure – especially in the fall when cold temps reduce the pressure in the tires. The cord is long enough so i can do all for tires on a honda accord (2018). I have a digital tire pressure gauge so i compared its pressure reading to this unit and they were within half a pound of each other. The reason i took off one star was that the unit is a bit awkward to use. Especially screwing the unit onto the tire valve and removing it. A clamp-on connector would be far easier to work with. The unit is not particularly fast at filling the tire but i never had to wait more than 3 minutes. I would not recommend this if you want to maintain several cars at the same time (it can get hot after 3-4 tires). But it makes the job of keeping tires at the optimum pressure much easier and at a reasonable price. It is also small and it can fit in a glove compartment or be kept in the trunk if needed (i just keep it in a drawer in a desk near the garage).

I bought this to replace an older one that the plug broke on. It does what it is supposed to do, it inflates things. I can’t comment on the light or accuracy as i have only used during the day and haven’t checked accuracy, but it is easy to use and has done what i needed it to.

My complaint would be that the carry bag that comes with this is wya too small. It barely fits this pump in there and can be a pain to get this in and out of the bag.

Decent product, used it almost every single day for about 2-3months if im not mistaken it ended up breaking on me from using it so much! Finally broke after using it so much, quiet not to loud compared to other air pumps, decently fast airfilled, stable and good for a few uses bought it on sale at the time for about $25-30 bucks if im not mistaken! Instead of wasting time going to certain places where normally have to pay with 4 quarters for air for me it was worth the $25 bucks because i used it everyday! Saved about 20-30$ bucks from quarters and time from putting air all the time! It lasted as it should typical products made with cheaper materials compared to others! But it had weight so it wasn’t so cheap cheap, other airpumps dont even have weight feels like they are paper or simply plastic whereas this airpump had weight which felt good and mad more material quality into it! I recommend to those who do not use these airpumps every single day abusing it and maxing it out all the time otherwise its a 2-3 month airpump based on my experience with it using it everyday… Thank you.

As far as the main function goes, it works great. It is quiet, and the gauge/preset pressure seems to be accuarate.
That being said. The preset function doesn’t work well for low pressure applications under say 10 psi.

Cord length: i found the cord length to be a shorter than i would like. It might struggle to get to the rear tires on a full size truck of you don’t have power in the back seat area. Also it makes it tough to air up other things (atv or trailer tires) you have to be pretty close for it to be long enough.

Built in light: i see where it could be useful at night. But wish it had an on/off switch. As is, if the unit is plugged in it is on. If you (or one of your kids) were to forget it was plugged in after filling up a bicycle tire or atv tire, you could come out to find your battery dead.

Putting air in my truck tires

Not super fast by any means but gets the job done. Beats an old hand pump, barely !

This little doohickey did the job just fine–it allowed me to top off the tires on my minivan at home without exposing myself or anyone to potential viruses. What a time we’re living in! I do have a few concerns, as follows:

1. Did not appear to work at first. I followed the directions, but when i switched it on, every time, it would start to shake as if working, then just stop. I checked the directions, the connection, the power outlet in the van, but nothing made it go. The light lit, the pressure reading and cut-off indicator worked, but it would not go. What gives? I worried that it failed like some of the other reviewers mentioned, but i refused to give up. I waited so long for it to get here. So i loosened the connection while it was still turned on. As the air hissed out, suddenly the pump kicked into life. Once it got going, it wouldn’t stop. Hooray! Four badly under-inflated tires brought back to service levels.

2. The connector screws on and feels none too sturdy. Another review lamented that the connector stripped after a few uses. I can see that happening. Take your time screwing it on, and try some lubricant/cleaner spray like wd-??, you know the stuff, first to make it easier to attach/loosen the connector quickly. As others have mentioned, it tries to push on for a bit after hitting the cut-off you set, to leave a little extra air in there in case detachment goes slowly.

3. There’s a bright yellow sticker on the housing that says, ‘hot.’ take this seriously. My pinky brushed against it while handling and got burned. Anyone with reduced feeling might want to take extra care around it. Do not let pets and kids near it. Also, watch where you store it after use. I could see this getting hot enough to start a fire if left against something. The information warns against prolonged use. I would agree with that. It doesn’t appear super sturdy, and got extremely hot after the first tire, which inflated 4-5 psi in less than a minute. If you’re doing more than one tire, give it a break in-between maybe.

4. Accessories. It comes with a bag for storage, and the cords wrap around the pump nicely. It also comes with the standard air pump tips for things like basketballs. Just be very careful if it runs long enough to get hot that you don’t store it with these things in close contact. If you’re traveling and use this on the road, watch where you stow it afterward if you want to just jump in and go.

5. Cord length. Just enough to hit all four tires of a an old dodge grand caravan while connected to the power outlet in the center of the lower dashboard. It wouldn’t have hurt them to make the power cord a little longer. I could see this being a problem in certain situations. For the most part, however, i think it’s fine.

6. Flashlight. Mmmeh… Not crazy about it, but haven’t used it in the dark. I could see it helping out if you’ve got poor lighting and didn’t bring a flashlight on the road. It’s fixed mount, so you have to hold the unit to direct it mostly, or find a way to prop it, but the cord length does not give you much room to play with positioning. If they made the flashlight swivel-mounted or something similar, it’d be a lot better. Not sure if it gives enough light yet. We’ll see. There is a handle, fortunately, so at least you shouldn’t have to fear getting burned while using, if you’re careful.

That’s pretty much all. I’ll change or update this review after a while if it fails or i find other issues you need to know.

Works good, just what i expected. Stay safe.

I bought this pump after reading several reviews of the best pumps available in the marketplace. Epauto 12v dc portable air compressor pump consistently showed up in the different reviews and opted for this pump. I don’t regret the choice. The reason i only gave it four stars because it doesn’t pump as strongly as i had hoped. Also, i needed a pump for my mountain bike, but it doesn’t come with a presta to schrader converter adapter. Basically, for this pump to work without this adapter you’re bike’s valve need to be the same as you would find on your car tire. Most bikes have the other valve. So, without this adapter, this pump won’t work if you wanted to use it to pump up you tires. I bought the adapter at the same time i bought the pump and it only cost me like 5 bucks for four. After attaching the adapter to my bike tires it was no problem. One thing i learned, you have to be sure that you fasten the pump thoroughly to the attachment, tighten it down as far as it goes. If you don’t it won’t really pump your tire very well. Also, it’s not a very strong pump so it might take a few minutes to pump up a completely flat tire. Also, i’m not sure how efficient it will be to pump up a car tire. I haven’t had the opportunity to try it. With as weak as the pumping action is on this pump i don’t think it would be strong enough to pump a tire with the weight of a car on it. But that is just a guess. That’s why no 5 star rating. Others may disagree, but that’s why we all have reviews, right? The cord is long enough and the built in light is very bright, so those two are 5 stars. For everything else, 5 stars.

I bought this to air up low tires in my f250. It takes about 10 min per psi from 50psi and up to air up my tire. Good for bike and small tires. Not good for truck and trailer tires.
