I'm lucky enough to have a few bikes. I have a saddle bag with what I need in it. Just having mounts on my bikes allows me to quickly move the bag from bike to bike.
I haven't tested other E-pumps but you can't go wrong with this one! I've only used it a couple of times to test it (no road flats yet!!) but if feels to be high quality. Size and weight seems to be the same as others that buddies have. Screen is large and readable. Battery seems to hold a charge (tested over a couple of months) and I believe you could get 2-3 inflations of a road tire, as advertised. I have a Magicshine radar taillight (about 8 months old) and couldn't be happier with it, so had a lot of confidence in this brand before purchasing. And with all their products, you can't beat the price!
My Lezyne multi-tool, battery pump tire levels and extra plugs all fit nicely in this saddle bag. The side straps hold it super secure under the seat, however the seat post loop is too big so doesn't grab much of the Velcro. Thankfully less important and I have twisted the non-Velcro side to make it shorter. The bag uses a very protective material. The zipper has a nice pull loop but worry about the zipper threads getting dirty and stop freely sliding. A little larger zipper may alleviate this potential.
