Review on Fumpa Mini Battery-Powered Bicycle Pump - Portable Solution for Efficient Inflation by Tre Boyer

I love this product very much. Of course, there's a trade-off between that portability and the larger Fumpa pump (I don't have a larger pump, I've only read about it). The downside is there is no pressure gauge on the mini pump so you know how much pressure you have. Insertion. So it needs a few measurements etc to get it right. Also a few times to get a rough idea of how long it will take to get close to the amount you want to deposit. The positive advantage of this model is its size. Easily fits in the pocket of my randonneur front pocket for travel and long trips. It's expensive, but it's a great idea and now you don't have to carry around a hand pump.
