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

Gauge doesn’t work - ordered twice

My partner first bought this as a Christmas present for our son. Only to find the gauge doesn’t work when trying to inflate his ITIWIT paddle board on Christmas Day. Returned the pump and I re-ordered, only to try again today and the gauge doesn’t work on the replacement either. Cannot use as we have no idea what pressure we are inflating the paddle board to. Very disappointed and a shame he hasn’t been able to use his paddle board yet.

Gauge not working!

Pumps air in quite nicely, trouble is the gauge doesn't work so don't know what the pressure is. I now have to return the bloody thing. I am not the first person to have had this fault either.

Useful hand pump for inflating water sports items

Was useful and relatively ligfht to carry about. While fast at earlier stages of inflating paddleboard, not so good when going about 10psi.

Tube unscrews from main body of pump during use

Ok, it does what it’s supposed to and it does inflate my SUP. It’s hard work, especially towards the end. The biggest issue is that once the SUP gets to a higher pressure around 7-15psi the tube unscrews from the body of the pump and I have to continually screw it back on again. Very annoying, especially since when this happens air escapes and it takes even longer to inflate! I have used this for almost a year, and initially I didn’t think too much of it. But this problem is worsening over time. Some advice would be welcomed Decathlon.

Gauge trouble

***HELP*** The gauge will not rise. I read that you need to pump and once the SUP forms shape, the gauge will work. The board was solid and the gauge still didnt rise. Im worried i will over inflate and damage the new SUP.

Its ok

Takes alot of work to use, good build quality though, and does what it says on the tin.

Does not connect well to SUP

The valve does not stay connected to the SUP so falls out unless held in place. Pathetic. Will be returning for a refund

Dear Tom,

Thank you for your recent product feedback. We are sorry to hear that you could not use the SUP pump properly. We have not seen similar issue before when we used this model of the pump in stores or during outdoor tests. Looks like your item had some individual defect. We hope you were able quickly to exchange for new model and enjoyed SUP activities last summer.

Once again apologies for any inconvenience caused.

Gauge stuck?

Used the pump to inflate my new kayak to the started 1.5 psi but when I removed the hose the gauge stayed at 1.5. It will not go down again and now I can't tell the correct pressure when using the pump again. Will be returning for a refund.


The orange tube snapped the first time we used it

Valve comes loose from pump

We have 3 of these pump, you need them of course to pump up the sup, do you can't have not one. All 3 of them have the same problem, the valve. Before buying ask information about this. Decathlon tell me they can't help me with in store purchases. So every time we want to use the sup, it is a struggle. Great service! Also telling my gender is ridiculous, reason why you need to tell gender :This information will be display. It helps to contextualize your review and makes it more useful. Odd

Works well, but not only for SUPs

Note this is the correct pump for the Itiwit X500 kayak, not the supposed "kayak" pump! It has a different connector and supports a higher pressure (up to 20 PSI) than for the other kayaks. Thanks very much to your store staff for swapping it and going to lengths to double check it was right. The pump is easy to use. As with other Itiwit products, it's clearly labelled on the pump that it has two modes, double pumping up to 5 PSI and single pump beyond that. It doesn't take long to pump up the kayak. The built in pressure gauge is great, much better than the separate one on the other models. As another reviewer mentioned, the hose does unscrew at higher pressures. I found I had to keep hold of the connector on the pump itself, hence 4/5 stars. The one on the kayak stayed perfectly.

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.

Technical dimensions

Height: 24.2" Width: 10.9" Depth: 3.9" Hose length: approx. 47.2" 70 mm diameter piston for easy high-volume inflation but high-pressure inflation takes a bit more effort. Pump weight: 3.1 lbs



Storage instructions
