12V DC 150 psi Portable Tire Inflator Air Compressor Pump with Digital Gauge, Auto Shut-Off, Sure-Fill Technology, and Carrying Bag

I bought this inflator to fill up my Jeep's tires to 36 PSI.The Good:This tire inflator filled up my car's tires with airThe unit is small, compact, convenientThe power and air hose fit neatly within the unitThe Bad:This inflator blew the fuse on 1 of my 3 power ports. I'm going to have to find out where to replace the fuse now.This unit does NOT auto-stop at the desired pressure level. My Jeep tells me what each tire pressure is. Once this unit hit 36 PSI, it did not stop and continued to pump air until my tire was at 40 PSI and I had to manually stop it . Do NOT rely on this unit to tell you pressure level.This unit's pressure gauge stops working when it reaches the set level. My vehicle showed 40PSI and this unit was frozen at showing 36 PSI.You will need to buy a separate pressure gauge to get an accurate reading.

This thing has been a life savor! It is so easy and convenient I've had mine almost 5 years and it still works great!

Functions great, exactly what I needed.

The first time I used this, it worked great. I connected power to my vehicles 12v socket and inflated all four tires to 38 psi and a go cart tire to 18.5. This machine comes with a decent little carry bag and some attachments to inflat various items such as sports ball, balloons, etc.Now, the second time I used this was in inflate a hand truck wheel to 25 psi. The tire was at 6 psi and only went up to 16 psi and boom, something inside the machine broke. Made a pretty loud sound I thought it was going to explode. I detached the hose from the tire and no air was being produced. I tried to request a return but I'm just outside of the allotted date.NOT a reliable product.

it was very good when I first got it, little noisy, but pumped till the preset pressure and I was quite happy. Skip 2 years later, it's been sitting in my trunk, got the low tire pressure signal, pulled out the pump, plugged everything up, everything seems to be working as usual, then noticed that pressure gauge is going all over the place. Pressure jumps from 0 - 37 or any number in between and the pump shuts off when it's over 32 (I preset it to 32). So I have to keep restarting but at this point I have no idea what the pressure of the tire is. Now I need to get a separate pressure gauge and use the pump somewhat manually.

Looks and feels cheap. My tires need 33psi but this one goes from 30 - 35 - 40. The tire pressure indicator comes on if pressure falls below 33. I have to over inflate the tires every time. And it is loud.

I purchased one and it was a great decision, it works great and very easy to use.. you just set the pressure you want the tire to inflate and the inflators does the rest automatically shutting down once the pressure is reached. While inflating you can monitor the actual level of air in the tire. It inflates quick and securely. I purchased 2 more to have one in each car, for my daughter, my son and my wife.

The media could not be loaded.  I purchased this for my vehicle. It is very easy to use with a resonable price. This can not only be used in car, but also can be used in other staffs such as soccer, basketball and etc. The only problem is the sound is too loud when the flator is working. Good item.
