Review on 🚗 DSV Portable Double Cylinder Car Air Compressor Digital Tire Inflator, 12V 150PSI Heavy Duty Air Pump with Auto Shut Off, LED Light, Extension Hose. Ideal for Truck Tires, Bicycle, Inflatables - Standard by Ian Iknokinok

I bought this to conveniently maintain proper tire pressure on my RV. When I first unpacked it everything was neatly packed and in place. Prior to use, I measured my RV's tire pressure with a standard tire pressure gauge. They registered at 70 psi. I connected the compressor hose and the digital readout read 66psi. However, I set the auto shut off to 89psi and turned it on. The compressor ran for about 10 minutes and only got 68.5 psi. I'm not sure the engine is too small to inflate beyond that, but the wording/selling point will have you thinking it's capable. I will repackage and return this product as it does not meet my requirements.
