I've got one of these Portable motorcycle tyre inflator it has a metal casing and comes in a pouch and is available from various outlets (I've no connection with any of them by the way).
It's tough as old boots (some videos about of UK Military using it) and inflates your tyre very quickly. It comes with a couple of options for connecting it and I find the crocodile clips straight onto the battery work best for me (R1200GS Adventure).
I use it frequently to adjust my tyre pressures between one up and two up as one day I'm out on my own, next day my other half is with me and/or we're loaded up. Also used it to reinflate after plugging a front tyre puncture.
However, there's quite a lot of other makes out there - I just chose this one and not disappointed, have used it a lot.
IMHO the sheer effort of using a hand pump would put me off adjusting my pressures most of the time and as for an absolute flat and possibly trying to reseat a tubeless bead with a hand pump - don't really fancy the idea of that.
