I bought a car for my work and it was always safe. It was nice and compact, looks really good, easy to carry and feels like I'm just carrying a water bottle. it already ran out on the first few uses, I think the product that came out of the box had a small battery, well, after I fully charged it, it's not that easy to run out compared to the first time I used it , compare with another inflator that i used before, this inflator was quieter, it has LED indicator, convenient for using things. I can charge my computer on the go when the battery runs out. This air compressor will always be in my car.
