Excellent pump

Excellent pump - 15psi on Itiwit 10' iSUP achieved in 5.5 minutes (about 180 pumps - 90 on low pressure, then 90 on high pressure) Awkward fit in backpack - Dec athlon could look into fold-able handles?

Hand pump

Works really well and easy to use

It’s ideal when you have super strength when you pump a sup. But it does the job

Stand-Up Paddle Double-Action Hand Pump

Overall an excellent pump. Very easy to use and inflates our 10 ft SUP in under 5 minutes. Very impressed with the build quality and value for money.

Seems a bit flimsy, particularly the hose but works effectively enough

icon-circle-checkmark verified purchase

This pump worked perfectly for me. The dual mode is super helpful for pumping quickly up to 5 psi, and then switching modes to pump up to 15 psi or higher (my board recommends 15 psi). I’ve had no issues with the gauge as other reviewers have mentioned. Some people may not realize that the board has to be pretty inflated before a reading over 1-2 psi will be noticed on the gauge. Another great product!

Hit and miss

Purchased with board. Gauge broke after 1st use. Travelled to nearest decathlon an hour away for replaceme t. Discovered that functioning replacement locks to board - great!last one didn't. But gauge doesnt work! Again! Why are decathlon selling such poor quality pumps!?! 4 hours driving is a lot of petrol for 2 broken guages!

does not deflate your SUP

I had assumed all pumps deflate...not ideal if you want to store your SUP in a small space

Hello Natalie,

I'm sorry to see your disappointed with the pump for your paddleboard. Whilst the pump doesn't have a deflate mode, for the majority of paddle boards this wouldn't be required as the air can easily be expelled by simply rolling the board up from the opposite end of the valve. Usually doing this you achieve the same level of compactness as you would by deflating with a pump, and most of the time at a quicker rate too!

I'll be sure to pass your feedback on to the product designers also and see if a deflate mode could be included in future iterations of the pump.

Many thanks

great piece of kit, I received an electric one as a gift after 18 months of manual pumping, but even still I do occasionally use this pump. Its ergonomic and comfortable to use.

Itiwit hand pump

Good pump action but hit and miss to get pressure gauge to show correct pressure.

Dosnt clip in

The paddleboard is brilliant, however the pump dosnt click in. This has been mentioned in other reviews. It twists, but dosnt lock in, so pops out when pressure is up.


Don’t have anything to compare it to but done the job perfectly so very happy

Sup inflation tips

1/ stand on flat and solid ground 2/ screw the hose onto the pump 3/ connect the hose to the SUP (valve raised) 4/ close the cap of the pump body, its double action operation delivers 3.6 L with each up and down stroke 5/ inflate the SUP until it reaches its full volume 6/ as soon as pumping becomes difficult, open the cap, the pump then operates in single action (1.8 L with each down stroke) 7/ inflate to the SUP's recommended pressure.

Storage tips

Roll up the hose, do not fold it Store the pump body and hose flat in the SUP bag. Do not stand on the pump or the hose. Clean off any sand, it can damage the seals.
