It worked great initially, probably got 10 to 15 pumps out of this thing with 17.5 PSI. Now the pump can only get up to 15 psi and the motor is sputtering in high pressure mode. Not sure how much life it has left.. Not ideal as I was looking for a hands off solution to get my sup fully inflated. So now I back on the lookout for the perfect electric isup pump once again. And now the hand pump is also required again. 2018: I Use this to pump up my paddle board to 17.5 psi which ideal for my board. I bought this to replace another pump I had which had a terrible quality hose, and was no long usable for high pressure. This pump takes about 8-9 minutes to inflate and the hose attachment is solid. The deflate option is an added bonus. Now I no longer need to cart around the hand pump and this pump is more compact for travel. Good value and quality for 18psi pump! Review: Inflates and Deflates SUP Board, easy to use. - Birthday present for wife. We tried this out in the driveway with SUPB. Much easier than using the hand pump which was almost as much exercise as actually using the board. The HR (Halkey-Roberts) valve on her paddle board (Ten Toes) is a bit wider than the cut out in the adapter at the end of the hose but was still able to get pressure to 15.5 just by holding the hose tight to the board. So far very happy with purchase though will try to find an adapter that fits the valve better on her board. Might just cut off the one on the hand pump but then that leaves the hand pump useless if ever needed. It took about 15 min to fill the board to 15.5 psi. Pressure was also verified on the hand pump gauge and both numbers agreed. Would recommend paying the extra $25 for this pump as opposed to their older pump which only inflates, though deflating isn't nearly the work load of inflating. The hose did get warm on the end near the pump but quickly cooled with just a little break in the action. Automatically kicked into 2nd stage and also stopped at the preset pressure. In only gave 4 stars because of needing to hold it to the board which is probably more of an issue with the valve in the board as opposed to the pump fitting. 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 ### ⭐⭐⭐⭐ Lasted 3 Seasons, Broke=totally dead, I fixed it. *by E***E on August 3, 2021* This has been reliable for 3 years until recently. So that is why I'm giving it 4 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! ## Frequently Bought Together - Seamax SUP20D 20PSI Double Stage Electric Air Pump for Inflatable SUP and Boat, New Version Intelligent Firmware with Built-in Temperature Sensor and Voltage Protection - SEA DOG WATER SPORTS Kit de reparación de embarcaciones inflables, 4 X PVC Patch, 2 X 30g Glue --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/64103516-air-pump-20d](https://www.desertcart.gr/products/64103516-air-pump-20d) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-10*
