---|---|---|
ABOUT DEFLATIONTo do the deflation, you should press open the air valve on SUP and lock it at the open position. First, let the SUP leak out all the high-pressure air until zero pressure. You may only need a few seconds to see the SUP getting flat after the loud air leaking sound. Then you connect the hose to the SUP to do the final deflation. |
3 PADDLE BOARDS IN A ROWBenefit from its temperature control feature, you can feel free to pump up to 3 SUPs without overheating damage issues. otherwise, this pump will auto stop if over the workload and give a beep sound warning. |
FOR LEAFIELD C7/D7 AIR VALVESThe package has included the compatible valve fitting for the special Leafield air valve. Seamax also has the original valve fitting kit for sale (Check with our Version 3 air hose kit) |

There was a problem filtering reviews right now. Please try again later.
Update. With a bit of trying the adapter suddenly locked on. Didn't get anywhere with pumping the board until turned on the engine of the car and then shazam, worked like a charm. If you are trying with the just the ignition accessory setting, turn on the engine and if like us you'll find getting your SUP pumped to full pressure is quick and easy. Def would recommend! Updated to 5 stars
A few weeks ago I handed it off to my sister-in-law on her boat, rafted up to mine, so she could finish pumping up her SUP (her pump wasn't pumping above ~.5psi...now I know why from reading other reviews:^)).
My pump just died, never started, done? I just used it on my wife's SUP on my boat so what happened?
I have two theories: one, the other boat's ciggy lighter port has a corroded connection which didn't provide high enough voltage and somehow this cooked my pump (weak theory); two is that my brother-in-law started his motor after my pump was plugged in and this surge (starter motor disconnecting) fried my pump (strong theory).
I like theory 2 as this is a well known occurrence in automobiles known as "Load Dump", all that starter energy in its coils dumps back onto the 12V bus creating a high voltage event. The Seamax has ZERO protection on its 12V input against high voltage transients. The 12V to 5V "78M05" regulator was fried only outputting 2.9V instead of 5V: this explains the total deadness of it as the microcontroller couldn't boot. I bought the 78M05 at Digikey for about $2.00 plus $8.00 shipping:^( It arrived and within about 30 minutes I had the Seamax happy again with its new 78M05. Note screws are T10-Security Pin, but a vanilla T-10 gets just enough purchase to back them out.
However, while inside the unit I added a TVS across 12V to GND, "Transient Voltage Suppressors". I happened to have a ~22V BiDir TVS on hand which will protect against > +/-22V events, and I added a 1N4004 in parallel to protect negative events beyond -.7V. If I had a UniDir TVS, no 1N4004 required.
So now my unit has a bit of "Load Dump" protection. Don't be too harsh on Seamax for omitting protection as most all automotive Aftermarket Products have zero protection too. So I'd guess ditto for Marine aftermarket stuff.
Seamax could add a single UniDir TVS across 12V-GND for about $.05, just saying.
Also, No, I won't let sister-in-law touch this repaired unit!
We know how much PSI we need and this is a good product. The directions are clear and easy to understand.
There is a lot of good information in the booklet that you should read first. We actually burnt our old one up because we didn't know that you had to wait in between blowing things up.
The price is fair.

I gave "sturdiness" and "durability" four stars each, but overall this unit gets five enthusiastic stars because a. it survived four years of outdoor use, and 2. it is fully repairable with good support from the company.
J'ai pensé qu'en payant 3 fois le prix du Lidl, j'aurais un article fiable pour de nombreuses années, mais je crains de devoir constater que ce n'est malheureusement plus le prix qui fait la qualité 😕
Es una maravilla, si un poco cara, pero después de estar bajo 40 grados, viendo cómo los demás están sufriendo al borde de la insolación y tú sentado en tu coche con el A/A mientras se infla sola, no tiene precio !!
