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.

Not suitable for all iSUP boards

I have given this only two stars as it does not work on my board.. Generally the pump seems well made and as with all Decathlon really good value!! But I purchased this as the pump supplied with my iSUP developed a fault and anyway I wanted something a bit lighter and less bulky when travelling by rail to reduce weight and create more space in the bag. However the hose connection to the valve in my iSUP does not lock into the valve, it just spins back out as soon as pressure is applied. So one hand would have to hold this in place. This makes pumping impossible or it becomes a two person activity. So I am returning it. I would recommend the pump but only if it had a universal connector to an iSUP valve


The paddle inflated in no time at all very good

The pump does the job BUT as soon as you get near to 10psi the corrugated tubing starts to unscrew from the pump, as a result this becomes a two person job to get to 15 psi one to keep the tube from unscrewing and one to actually inflate the SUP. Took it back to my local store to swap it thinking it was just a faulty pump but no more in stock (I have been Informed there has been some on order since last week) I have therefore kept the pump for now as we wanted it for holiday...will be refunding it upon return for a new one. Whilst in store another gentleman noted he had the same isssue with his, so it would appear it is not isolated to mine. Would be great if there was a really good larger capacity pump with interchangeable connectors as I also have an inflatable kayak so have to take two different pumps everywhere! Like I said it does the job but need two people which defeats the object!


working good, anyway capacity is too small it should have two tubes

Wrong pump

Bought this as it has the gauge and is same brand as the kayak I bought at double the price of others...turns out its the wrong pump for the kayak :(

Pump not labelled - take care to get the right one

I was sold this to pump a kayak - there are no labels on it stating purpose - when I got home and checked it online found it is a specialist pump for paddle boards. Two hour round trip to my nearest store

Great for 6 months but broken

This pump worked great for 6 months but the internal seal has broken on mine and now doesn’t work.

Gauge DOES work after all!

I note from the reviews below people like myself who assume the gauge doesn't work because they don't know that they have to keep pumping for a while until 3 - 4 psi. I returned one pump because I didn't know how much pumping is required. The simple solution is to add some instructions to the packaging - I only discovered the facts by looking online at your website

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.
