Description

Chosen by over 100,000 outdoor enthusiasts Dual-Cylinder High-Pressure Pump Powered by a dual-piston high-pressure system, the Seawolf electric SUP pump maintains strong airflow as pressure builds. It delivers 90 to 100 L/min during the high-pressure stage and inflates a standard 10'6" SUP from 0 to 12 PSI in approximately 4 minutes. Faster setup means more time on the water. Longest Group Runtime Fastest for Family Trips Compact for Solo Trips Dual-Power Flexibility Fast 12V Inflation 12V Ultimate Convenience 12V Car-Charge Basic What are the obvious differences between your Seawolf pumps and other air pumps on the market? Swonder Seawolf pumps have a Dual-Cylinder High-Pressure Motor, doubling the inflation speed compared to single-cylinder pumps. With recent upgrades, they inflate a paddle board in 5-6 mins, while other air pumps on the market take 9-10 mins. How many models are there in the Seawolf pumps? As of now, there are a total of four models in the Seawolf pumps, namely S20Li 10000mAh (discontinued), S20Li 9000mAh, S20Li 6000mAh, and S20. What are the most obvious differences between the different models of Seawolf? The S20Li 10000mAh and S20Li 9000mAh models are battery-powered and serve as a power bank. The S20Li 6000mAh is a hybrid version with a smaller battery but can also use a car cigarette lighter. The S20 relies solely on car power, with no battery. Can the Seawolf pump inflate my paddle boards/kayaks/inflatable boats? As long as your paddleboards/kayaks/inflatable boats have suitable valve connectors and work under 20 PSI, the Seawolf pump should be able to inflate them. The Seawolf pump comes with Pinch valve, Boston valve, Round valve, 805 valve and H3/HR valve. How do I know the Seawolf pump is safe to use? The Seawolf pump already got the CE/UKCA/CP65 certifications, offer you a promising summer journey.

    • High battery capacity and fast inflation
Color: Cyan/Tangerine
I read lots of reviews before purchasing a paddleboard pump. This one was slightly more expensive than most I was looking at, but it was the reviews that convinced me. I have used it a handful of times now, once on a camping trip where I inflated and deflated two paddle boards two days in a row, and the battery still had enough to do more. I love that it shuts off at my pre-set psi. The first stage is remarkably fast and so quiet. The second stage is loud, but no louder than the other pumps I hear on the beach. I’m grateful that this has a faster inflation time than the others I researched, because I wouldn’t want the sound of the second stage to be drawn out for longer. It comes with several different connectors and different gasket sizes to ensure a tight fit with the device you’re inflating. It seems well built, though time will be the test of this. Ultimately, it’s easy to use, works perfectly and quickly, and the battery capacity is fantastic. I don’t regret my purchase for a second. ... show more

    • Worth every penny!
Color: Black/Red
Cannot believe I spent two summers without this thing. We love to paddleboard but it was becoming more chore than fun to take our inflatable boards to the lake. I was so exhausted by the time I got both boards inflated with our bike-pump style pumps that it just wasn't worth it. I finally bit the bullet this year and invested in this electric pump and I could not be more pleased. It inflates the boards to the perfect pressure and then automatically shuts off. It only takes about 5 minutes per board. I can relax and the kids can play while we wait and we are on the water in record time. It does get a little loud about halfway through inflating as it works to get to pressure but it is quick and doesn't bother me. It was easy to learn how to use as well. Holds it's charge for a few trips even with inflating 2 boards each time. And at the end of the day, it deflates even quicker so we can load and head home without waiting for them to be foldable. Excellent product and I will never go back to hand pumps. ... show more

    • Perfect for my SUP
Color: Cyan/Tangerine
Best thing I've bought in years. I have 2 Stand up paddle boards (SUP) and was always exhausted hand pumping them until I found this. You set the PSI and just let it go. Stops when it reaches the setting. I've blown up 4 boards at once and barely used 1/4 of the battery power. Charges back up very quickly. It is noisy, once it gets to high pressure, but no horribly loud. Now I can take my board everywhere and not worry about get them blown up for use. We use them much more often now. ... show more

    • Great pump. Very high quality, good charge.
Color: Cyan/Tangerine
Pumps up pretty quick. Enough charge to do multiple boards, or not need a recharge. Quite quick, though still limited by physics. I haven't timed it but it still takes between 5-10 min per board (7 min?). Set it and forget it, since it automatically stops at the desired pressure. The attachments can take a bit of effort to connect to the board, but it's because they use durable plastic, so just be patient and it gets easier with practice. I've had the tubes on cheap pumps fray and break. Looks great aesthetically. ... show more

    • Pump stops going to stage 2!
Color: Cyan/Tangerine
This is a great pump…. While it works.. I saw several reviews and we decided on this compact pump that has 2 stages. Like several others, it works great and is accurate and easy to use. Last summer we used this 10-12 times. We took it out first time this year and now it won’t go to the second stage. Stage 2 is needed for SUP’s so it’s useless now. We were hoping to get a replacement on the 1 year warranty but haven’t received any response from the company as of June 3, 2025. ... show more

    • Verified Performance – Real-World Battery Life Test Results
Color: Cyan/Tangerine
I wanted to leave a detailed review based on actual usage of the Swonder Seawolf S20Li pump, and I’m very impressed with the performance so far. We will see how things go over time and more use. I tested the pump by inflating three 11′ x 34″ x 6″ paddle boards to 15 PSI—back to back. Each board took about 7 minutes, consistent with the dual-stage airflow spec (100L/min in stage 2). After inflating, I deflated all three boards using the same pump and let the cooling fan run afterward. At the start, the pump was fully charged and showed 12.0V on the screen. After all inflation, deflation, and fan cooling, the display showed 11.6V and 3 bars still remaining on the battery meter—suggesting I’d only used about 25–30% of the battery capacity. This confirms the Swonder Seawolf's internal 9,000mAh (approx. 108Wh) battery is the real deal. Based on this test, I’d estimate it can inflate 6–7 full-size paddle boards to 15 PSI on a single charge under normal conditions. Other highlights: Dual-cylinder inflation although a little on the loud side, is fast and smooth, without overheating. Deflation mode works efficiently and saves space when packing up. The auto-off and digital PSI monitoring make it easy to use. The cooling system ran quietly and didn’t noticeably drain the battery. Overall, this is one of the best battery-powered paddleboard pumps I’ve used, and it outperforms many competitors that advertise similar specs. If you're looking for a reliable, high-capacity pump for group outings or family trips, this one truly delivers. Highly recommended. ... show more

    • Great Customer Service to go with a great pump
Color: Black/Red
I really love the pump. It works great to inflate my drop stich boat to 15 lbs. The internal cooling fan is a great feature. The battery lasts a long time. Everything was working great so you I can imagine my disappointment when the pump stopped working after several months. I reached our to Swonder Pump through Amazon. Harper responded very quickly. He was very responsive and great to work with. I missed one of his emails and he reached back out to me saying he hadn't heard back from me. You never see that happen. All I had to do was send him a video showing my issue with the pump. Harper immediately sent me a new pump after seeing the video. I got the new pump in a couple of days and now everything is working great. I highly recommend the Swonder pump. ... show more
