Hi Patrick,
I've used one of those Wonder Pumps for seven years, to top off and also as my on-boat pump in case I have to an on-river repair. For regular total inflation (and particularly if you have a large boat) they would somewhat tedious to use, and might not stand up to the task over time. But if you don't mind the time they take to use, and every now and then can replace the internals, you could be OK. Or at the price, just buy another one, I suppose......
A few other thoughts. Some folks have found ways to use a cheap battery-powered leaf blower to do the major work, and then top off with something like the Wonder. Others take the plunge and buy an LVM or similar 12-volt pump and run it off their car battery. Of course if you are near a 120-volt source, then other kinds of high-volume, low pressure options could come into play, like a shop vac.
FWIW.
