I bought two of these little units in October of 2025. Opened both units, made sure they functioned, charged them up, and put them back in their boxes. Stored one in my wife’s Toyota Camry. Shelved the other one. I purchased them after a flat on my wife’s Toyota Camry required me to use the “toy spare tire” provided by Toyota. I will not go into details but something to pressure the “toy spare” up to its proper psi would have really helped.Fast forward to August of this year. The tires on my Dodge Ram 1500 pickup truck for some reason, known only to the gods and Dodge, lose pressure if the air temperature gets too hot or too cold. And it’s been hot in this part of Texas. Recommended tire pressure 40 psi. My tires were LF 34 psi, LR 33 psi, RF 39 psi, RR 36 psi. Before dragging out my air compressor, hose, extension cord and other needed tools I decided to try the Inflator on one of the tires. I located the shelved Inflator, opened the box and was surprised to see the internal battery was still fully charged. I attached the Inflator to my LR tire, set the pressure to 40 psi, turned it on and left to get the 120 volt compressor and extension cord. I returned to my truck and noticed the Inflator was no longer running. I thought dang, well you get what you pay for. I walked over to the unit and was “blown away.” The unit had cut off because it inflated the tire to the required pressure. It had reached the proper pressure in less than 10 minutes. I used the unit to inflate all four tires in about than 20 minutes. Sure, I could have inflated all four tires a little faster with an AC compressor but that’s not the point. These darn things work and work well.
