I got this for travel purpose, since you can't bring CO2 on planes. I liked that it had a somewhat larger battery capacity than the popular unit that I saw on Amazon. We took a trip last weekend and this pumped up the tires on both my bikes and my friend's bike. Not from full flat, but still it had to do work on all four.
Maybe the worst thing I've bought in 33 years of serious cycling. I tried to inflate tubeless tires from flat and instead of inflating sealant came spilling out of the valve. Works fine with tubes but if you run tubeless save your money.
I was surprised on the first use when the battery died after refilling both tubeless tires to mid-30s PSI. Probably wouldn't have bought it knowing that going in. It is nice being able to dial in your target PSI and stop when it gets there.
Life changing! I'm never going back to having a giant pump in my back pocket when I'm just riding around town.
I've been looking for a product like this for quite some time. I love how compact and light it is, I can take it anywhere I go and top up my tires out on the trails. 10/10 recommend!
I fully charged the E-Pump Pro and then attempted to inflate a 700 x 28 tire from 0 PSI. The pump inflated the tire to 32 PSI and stopped with a fully discharged battery.
