This is the simplest version and you can inflate a stand-up paddle with it but it will take time (10 minutes) as it only pumps air when you lower the handle.
It is generally found in entry price all-inclusive packs (SUP + pump + paddle).
Please note, considering the pressure required to properly inflate an SUP (minimum 15 psi or approx. 1 bar), the final pump strokes are more difficult than the first. You will need to use your body weight over the pump to be able to push down the piston to counter the resistance.
