So far I am really stoked about this little beauty! Have used it to fill gravel and road tires, up to 2 tires on a single charge from low 20s to 40 and 80 respectively and still had charge left. It's loud and it gets warm but a small price to pay to have it in the seat bag! Have stopped carrying CO2 and I have high hopes for at least a year or two. Best feature by far is the pressure reading, setting and automatic shutoff. Pressure gauge appears be accurate based on my highly calibrated squeeze the sidewall tests. I have already recommended to 2 of my riding buds and so far so good. I recommend this mini pump and keep my fingers crossed for it lasting at least a while!
I usually don't buy products that are new to the market, but a mini compressor has definitely been necessary. This thing has been very reliable. I've used it about 5 times in the last few months. No issues and good battery life, in my opinion. It's a great competitor to the more expensive ones when it's on sale.
Used this pump on several flats inflating to 90 psi. The pump shows charge level, getting about three inflates per charge. The pump is loud and somewhat heavy, I carry it in a fanny pack with lunch on longer rides, The controls are a bit tiny, but workable. Pleased with the pump!
Hard to get started - had to push start button repeatably (was fully charged)!
Tire filled to 45 psi easily - unit did get warm! The presta valve hose connector is too short to stay fastened to presta valve - it works but needs watching!
