ENGREPO 12V Electric Portable Air Compressor, Digital Tire Inflator Build in Rechargeable Battry. Tire Pressure Monitor and Preset. Pump to 150 PSI - Silver

Just got this a few days ago so I can't comment on durability or all aspects of performance. My first suggestion to the vendor is: please hire a native English speaker to completely re-write the brief instruction pamphlet! It's funny, but I don't think that was intended. Beyond that I can report that it seemed to work OK in two trials topping up automobile tires that were 3-5 PSI low. FRecharge time (from house A/C with included charger) was reasonable -- 10-15 minutes after a 3-5 minute usage (an LED turns green when it's charged up.) And it is great to have something I can take in the car and that doesn't depend on the car's cigarette lighter for power. Other minor (or TBD) issues: (1) you have to stand and hold the unit while it's operating because the pressure hose is just a few inches long. Not too bad, but even topping up a tire took several minutes. (2) The unit is supposed to stop automatically once the pre-set pressure is reached, but in my two first tests it did not cut off--I just stopped running it after a while and the pressure was at or slightly above the target (as measured by my other pressure gauge.) Maybe I need to do a longer trial to really determine if the automatic cut-off is working. All in all, this seems so far like a good, inexpensive piece of insurance, and will save me trips to the gas station air pump at $1.50/pop.

I purchased this pump last year and used it a couple of times successfully. Sure, it was slow and would get very hot after 10 psi, but it was working. Last week I go to put air in a tire with a slow leak and upon trying to plug it into my cars charger, the plug fell apart, as show in picture. All the metal pieces just popped out. I tried to charge it in my house with the other cord provided, but the pump won't hold a charge for even a second. I contacted the company to see what they could do, and their response was that they could do nothing for me, not replace the faulty product or refund me.

I am submitting a 5 star rating for this really cool, portable high pressure pump now that I've had a chance to use it in multiple ways. It's so convenient! I was able to top off my paddleboard in a few minutes (if you have a Halsey valve you'll need to purchase the $15 attachment that has a Halsey valve on one end and a car tire valve on the other end on Amazon), and it shut off as advertised. I also topped off the air in my car tires with ease.Obviously because this is essentially a battery powered pump, it gets really warm on the valve and near where the valve connects to the pump.The one thing I haven't tried yet because I'm not sure it could handle it is trying to inflate both of my inflatable 15psi paddleboards one right after the other.If someone else would try it and then tell me how it goes I would greatly appreciate it!

HOORAY! Have had several issues with "low tire pressure" indicator, and can never find "service" station with air available. Either out of order, too busy, or I don't have the $$ required, and the station is closed. So damn frustrating. Opted to try this, and sure enough the other day, that red light came on. So, I pulled out this compressor, and brought all 4 tires up to 35# pressure. Works like a champ - as advertised. Very small and compact. Only downside is there's nothing to indicate the level of charge. I recharged it after using it this once, but don't know how long it will hold. There's a 9V adapter included for "emergency" use, but I'd prefer to keep it charged via DC. However, in spite of this, I still consider it a great little investment for piece of mind, and I'll just have to remember occasionally to give it a "recharge" - and hope I don't screw up the battery! (So, for this design weakness, I subtracted one star!) :-(Update: (From 4 stars to 1) July 2018 - the friggin' thing has died. I've charged 3-4 times since purchased 11 months ago. Have only used it twice to pump up car tire from 25 psi to 35. And just now, when I need it again, it won't charge. AAA, please help me out! And I guess I'll be looking for another one. (This model right now is not available... so at least you won't be spending good money or somethin' that doesn't last. Like me!)

I like the fact that I don't have to carry a huge compressor or a manual pump to air my bike, car, and toys. Use button and adjust the tire pressure up or down and it stops when the desired pressure is reached. I used it to pump my car from 22 psi to 35psi with no problem and then air my bike. It has a light that can be used in emergency situations. The tube did get warm but not too hot as expected when you try to compress air in a small diameter tube. Very useful, compact and lightweight. It has some attachments for other uses. Fits the glove box or any storage. Although my unit gave out after a few months of use, I contacted the company and they promptly responded to my concern. They were quick to resolve the issue about my defective unit. They have earned my business!

I love this small air compressor.1- It is small and quiet2- It stops at the desired pressure, and I have checked it after stopping, the pressure is exact3- It holds a charge so that you don't have to remember to charge it before you take it outYou have to use it for what it was intended for, which is small jobs. Topping off your car tires works fine, but I wouldn't use it to inflate from scratch.Having said that, I just inflated both tires on a motorcycle where the tires were down to 3psi, took them up to 36psi and the battery was still going fine. I also tried it on soccer balls, and it is very convenient.This is now my go-to garage inflator instead of firing up the compressor.

Bought this to keep in the backpack while commuting on bicycle, took the tires from 50 to 70psi in half a minute. Gauge seems very accurate and it automatically shuts off at the desired pressure. I have a small hand pump in the bag for absolute emergencies, but it's nice to have effortless inflation in emergencies or for regular maintenance. Just got it today, so I'll update this review by request or in 6 months of commuting ~30mi a day. I wish it was packaged with an AC charger that had a higher amperage rating, this one seems to barely squeak by and gets hot while charging.
