The Slime 40051 12-Volt Digital Tire Inflator is made with advanced technology that delivers precise results. It enables the tire inflator to be set to the desired pressure and the machine automatically shuts off when the level of pressure has already been attained – and both of these can be easily done with a simple press of a button.

Despite the Slime 40051 12-Volt Digital Tire Inflator being made using advanced technology, the tire inflator itself is not difficult to operate. You can simply put the whole thing into running by just following three (3) simple steps.

First, you have to make sure that you screw in the Slime 40051’s connector into an air valve stem to start the ball running. Second, you take hold of the power cord and plug it into a power accessory outlet.

Third, and final step, set your desired range of pressure and then press the power button to start the tire inflator. You will be guided by the pressure value to be added since the Slime 40051’s LCD display reflects the current pressure of your tire.

The accuracy of the Slime 40051’s result is also partly due to the machine’s accurate digital gauge, reading within 0.5 Psi to 2 Psi of a manual gauge.  The display is likewise backlit with bright LED light – a convenient feature to have when you have a flat tire in a dark place or in the middle of the night.

When the Slime 40051 has already achieved the targeted pressure value, it turns off on its own – taking out the risk of giving the tire too much air that will damage the wire and prevent it from functioning fully as well as saving the owner from the need to constantly monitor the tire inflator and the tire and, as a consequence, sparing the owner from putting in too much time and effort in inflating a flat tire.

Finally, the Slime 40051 is no hassle when it comes to storage. It has a big cord compartment where you can hide back the air hose and power cord after use. Also, the screw on the valve attachment allows the Slime 40051 to take less room for storing. It also makes connecting, as well as disconnecting, the tire inflator easier.

Also, the 12 feet reach of the cord makes it possible for you to reach all four (4) tires just as easily without having to move the Slime 40051 every now and then.


The Slime 40051 12-Volt Digital Tire Inflator has also some reported drawbacks that one should consider first before purchasing the tire inflator. First, the inflator can get loud when running, especially when used in an enclosed space.

The Slime 40051, however, is not as loud as the typical 12V inflators available today. Second, it does the work but does it not too fast.

You have to spend a little more time with its 35 Psi capacity.  And third, the plastic screw cap has the tendency to loosen its grip on the valve after quite some time so there is a need to monitor the screw cap once in a while.

Final Verdict

Considering both the pros and cons, the Slime 40051 12-Volt Digital Tire Inflator’s overall performance is something to be lauded and considered.

There may be some reported issues with the tire inflator itself, but those reported drawbacks are not major enough to overshadow the many positive results you can get from the tire inflator. The Slime 40051 remains to be a handy and dependable device for your vehicles. It is definitely a highly recommended buy.
