Review on Dual Cylinder Air Compressor Pump by FORUP - High-powered Portable Air Pump, 150 PSI, LCD Backlit Digital Display, Automatic 12 V Tire Inflator for Car, Truck, RV, Bicycle and More Inflatables by Black Holstead

In the beginning everything went quite quickly and worked well. The specified time to inflate a car tire. However, today I tried again (because my tire was a little low) and the tire pressure was 28psi and when using the supercharger it dropped to 18psi. I thought there was a leak. I checked the hose (not cold so put on gloves) but couldn't find a leak. After the second try, I noticed that some air was coming out of the bracket that screws onto the tire. Thought there must be a leak. How else is the air pressure injected into a tire increased from 28psi to 18psi? Only used 3 times and I need to speak to the warranty department. This product has problems.
