The same Coleman pump also comes in a rechargeable model.
As for hand pumping, … if your 'toon has Halkey Roberts type valves, lock them in the DEFLATE position to get 90% of the air in, then pop the valve to INFLATE and top them off. That way, you’re not pumping against the spring loaded valve stopper.
