Review on 🚗 Inflate-R - Portable Electric Air Pump for Car Tires, Emergency Tire Inflator with LCD Display and PowerBank - Inflates up to 150 PSI by Phil Kowal

I bought this product to use on my cars. My truck tires are 45psi. I received an Inflate-R which charged the device for 4 hours until the green light came on. I had one that was only 36psi, I set the tool at 45psi, at 45 it cut off, great. Inflated the second tire from 39 to 45, block shut off at 43psi. The battery is dead. Charged the device after 6 hours. On trying again, I was only able to inflate one tire to 45, another to 45, and the last one to 42. It works, but not as expected in the manufacturer's review. It works well with my garden tools. I was able to inflate my lawnmower tires from 4psi to 10, my wheelbarrow from 8psi to 30, and my hand truck from 4psi to 60 before the battery died.
