Electric bike pumps are a recent phenomenon and a success story. In the space of just a few short years, they have gone from seeming a bit unnecessary to total acceptance and are fairly commonplace now on my group rides.
Whilst most pumps of this type concentrate, understandably, on compactness and low weight, the Silca Elettrico Ultimate Inflator majors on power and capacity. Silca claims that it is the equivalent of carrying nine CO2 canisters (presumably the 16g type), making it capable of pumping up multiple road or gravel tyres on one charge.
