Valve connector detaching with desired pressure: When you detach the valve connector, the tire valve would keep releasing air until the connector is fully detached. It’s normal and can be accepted by setting up desired psi value on the machine. For example when you set 32 psi, the machine will keep pumping to 32.5 psi before it stops which consider the loss will be happening when you detach the valve connector.

Expert Reviews


What reviewers liked

While its CE certification can be welcome news, it is the presence of an integrated overheat protector that will give you peace of mind every time you use this tire inflator. The overheat protection system instantly shuts off the device if it reaches a temperature exceeding 167OF.
Due to its auto shut off technology, it provides you the convenience needed when inflating your vehicle’s tires.
You can inflate tires of cars, bikes, SUVs, trucks, and various other inflatable objects by changing the nozzle. There are 4 different units available on the display screen for the measurement of tire pressure accurately.
The display is easy to read with 4 units: PSI, KPA, BAR, and KG/CM.
This is probably the best tire inflator in the market. EPAuto Air Compressor Pump is compact for sure, and with this, you get the convenience to carry it easily.
The unit is more silent in comparison to other types and doesn’t vibrate too much. It can also be placed on various surfaces without any issues.
-
It will shut off automatically as soon as it reaches the necessary PSI level.
The overheating protection eliminates risks of damage even when it is overloading.
I was also delighted to learn that you just have to set to the pressure you desire, and then once it reaches it, the compressor goes off. It also features a very bright LED flashlight that you can use when it is dark.
For the convenience of the user, this product allows you to plug it into the cigarette lighter socket. More than this, the display on this compressor is very easy to read as well.
The EPAuto is the most portable air compressor on this list. Weighs 3 pounds, meaning you can conveniently handle and move it about. It makes an excellent equipment in the trunk.
The auto shut off feature is the best one that shuts off the inflation automatically when the required amount of air is filled up with the tire prevents it from bursting.
-
We were impressed with the pump’s elaborate safety system. It will automatically shut off when the tire reaches the desired pressure levels. The manufacturer has taken measures to prevent overheating as well. The other advantage we drew from the led flashlight. It provides bright light for nighttime pumping.
This pump is very convenient to use because you just plug it directly into cigarette Lighter Socket of your car. You set the desired amount of pressure you need and when it’s reached it automatically shuts off.
-
Auto shut-off at correct pressure. Reads in PSI, BAR, KPA, and KG/CM. Also has an effective torch. Rated very highly by owners.
The EPAuto 12V DC portable air compressor pump has a lot of user-friendly and safety features such as its auto shut-off feature, the large digital display, and the automatic overheat protection.
Another good reason to get this air compressor should be that it allows for multiple uses. You will find that with this single product, you can inflate tires on cars, sedans, bikes, and midsize SUVs. This makes it good for someone who might have different types of vehicles.
It provides accurate readings and lets you program it to stop when it reaches your desired PSI. It also is a great size for a portable unit and sold at a decent price.
Another cool feature which we like the most is that it has an inbuilt auto cut feature which will prevent over inflation. You can set a limit of air inflation after it will auto cut.

What reviewers didn't like

It takes some time to raise its pressure levels according to some portable air compressor reviews
Our primary concern is that pumping slows down when the display unit is at a higher mode of PSI. Also, the light on the unit cannot be turned off.
Will not handle truck, pick-up or large SUV tires. Combined reach of air hose and cable just 10 feet.
The power cord is only 9 feet long. While this is long enough to run from the cigarette lighter to the tires on most cars, this length is the absolute bare minimum length you should have.
Does not work for truck tires
The main problems include that it is not heavy duty, so you cannot run it for long periods or use it too much without causing trouble and that the screw on valve allows for air to escape, which means you have to add more air than you really need to get your tires at the proper PSI.
However, it will not be recommended to fill the air on the truck and more substantial vehicle.
