GSPSCN Portable Silver Tire Inflator, 5.65 CFM 12v Air Compressor Pump, Heavy Duty 160L/min,150Psi, Auto Air Pump,for Car, Truck, RV, ATV, Lawn Mower and Other Inflatables

Just received it today. I use it mainly for off roading purpose. It stated clearly that the gauge won't be accurate under 50 psi. So all you need to do is do a bit test and get the correspondence reading. I use it to inflate my 275/70R18 tire from 30 psi to 40psi. Done within 1 minute and when it shows 60 instead 40. Happy with the product! Solid build.

Great product although the the pressure gage is not accurate on trucks

Lets face it - how many of us drive a car or a truck with 50+ psi in each tire? NONE !!! I missed the part where it states that. And the gauge on this inflator is a joke - it shows the pressure of the inflator, not the tire. I had about 26 psi in my tires and I decided to add air - connected the inflator's hose to the tire and went back to the unit. Obviously did not see the gauge. Turned on the inflator and went back to the tire to check on the gauge. THe gauge was showing 50 psi. Getting hit with cold sweat I run back to the inflator and hit the "off" switch. Went back to the tire and saw the gauge showing 25 psi. Went back to the inflator and hit "on" switch. Went back to the tire and got that cold sweat again and run back to the "off" switch. After that I realised that the reading was way off. I saw 50psi inflator in Harbour Freight for $55 which was American made and about 1/4 of the weight of this inflator. Cons: on/off button should be next to gauge. 2. Gauge is not working.3. the unit is way too heavy to be called portable. May be a good unit for heavy machinery but not as specified on the add

Beware, fixings are not standard. You can not add on an additional hose if you need extra length.

Worked on GMC Yukon. Works off battery. Easy to use and portable.

Fast, but heavy

The media could not be loaded. Updated- We use this inflator on vacation one week per year coming off the surf fishing beach. The first year it did great. The second year it was used the same way. Inflated 275/70r17 tires from 20psi to 50 psi. It takes just less than 20 minutes which is great. The Inflator developed a “mechanical knock or tap” that didn’t go away when cooled down. It sounds sloppy now. I’m sure it’s just a matter of time before it lets go now. The inflator has been used 12 times, once a day for 18-20 minutes at a time.Original review-It is heavy duty and fairly large as well as heavy. Only four stars because you have no way to regulate the final pressure you’re pumping up to. It worked excellent with no problems using several days in a row for all four tires inflating after coming off of the surf fishing beach. It gets screaming hot on all of the metal fittings and pieces. I couldn’t put it directly in the case after using. Burnt two smaller compressors up last year that plug into a 12 volt dash plug. They would take 20 minutes per tire. This one took about 5 minutes per tire going from 20 psi to 50 psi.

So far so good!Really cheap case. Didn’t last.Will update after longer use.
