At first, I was excited about this portable tire inflator. It was compact, easy to use, and had a built-in LED flashlight for nighttime emergencies. The digital gauge seemed accurate and it even included a plug for inflating sports balls. However, after a few uses I noticed that it struggled to inflate my car tires to their recommended pressure. It took longer than I expected and the device became quite hot to the touch. Additionally, the noise level was quite high which made it difficult to have a conversation while inflating. Overall, this tire inflator may be useful in a pinch but is not the reliable, efficient tool I was hoping for.
