They have foot operated pumps that work well too.

Foot operated are OK, but nowhere nearly as good as the pump we got when we
finally gave the old foot pump the heave-ho.
You can buy a large diameter hand pump that pumps on both the upstroke and the
downstroke. We can fill our Zodiac inflatable in about 350 strokes, a pull toy
should go up in under a minute.

Working up a sweat with the hand pump
provides a perfectly acceptable excuse to reach for a cold malt beverage. Only
a serious wimp can claim dehydration and fatigue resulting from the use of a
12-volt power pump. :-)
