I really like the small Air Head pump I bought for my two inflatables (2015 i12 and 2016 i9).  
https://www.amazon.com/AIRHEAD-AHP-12H- ... rhead+pump  It does not pump to full "Hobie pressure" required, so I just finish it off with the manual Hobie pump supplied.  You know when the pump has reached it's maximum pressure, as you hear the rpm pick up (similar to a vacuum cleaner when it is up against it's maximum head displacement).  The other issue is that the air valves have to be open when using the pump, so you lose a little pressure until you can get your fingers on the valves and get them closed.  In the long run, it saves lots of time and sweat in 90+ temperatures.
