Review on 🚗 GSPSCN 150Psi Portable Digital Car Tire Inflator with Auto Shut-Off & LED Light - Heavy Duty Double Cylinders 12V Air Compressor Pump for Auto, Truck, Car, Bicycles, RV, SUV, Balls (Titanium) by Mark Sutovsky

Removed the LT265/75R16 tire on a 2502 Chevy 2500HD from 65 PSI to 80 PSI in 5 minutes with the compressor connected directly to the car battery and the engine running. Given the size and weight of this compressor, I'd say it's acceptable. The smaller tires were obviously faster. The compressor was the same temperature as when a Chevy tire was installed. I would suggest running this compressor directly from the battery (higher voltage with faster pumping) with the engine running rather than trying to figure out if your accessory outlet can handle the load. The battery terminals are pretty weak, but they work. Bestek has a heavy duty kit that I bought. As an aside, my '02 Chevy 2500HD isn't a supercab, it has an 8" bed, and the air-hosed power cables just barely go diagonally from the rear wheel to the battery. The solution might be a Bestek 12-gauge extension cable, which I also purchased Thanks to the extra length it is also possible to achieve a towed trailer.Everything that comes with the compressor fits easily in the bag that comes with it and the other two items I added also fit.Good bag. I have found that the pressure gauge on the compressor is within 2psi of other gauges I have and as others have pointed out the compressor does not shut off when it reaches the target pressure you have set it will continue to work but the Pressure stays at set level Not so hot whats going on The screw on the included valve stem fitting is acceptable If the compressor holds up then it is the purchase satisfied.
