Features
- HIGH-CAPACITY BATTERY: The Seawolf electric air pump boasts a robust 9,000mAh lithium-ion battery, capable of inflating up to 12 paddleboards on a single charge. Its cordless design enables you to hit the water wherever you desire without relying on cars or larger boats.
- 2x FASTER INFLATION: Equipped with dual cylinders instead of the single cylinders used in traditional pumps, the Seawolf maintains a steady 100L/min airflow in the high-pressure 2nd stage, inflating 2x faster than typical products with a 75L/min airflow. This allows you to inflate a paddleboard in 5 minutes or less and deflate it in as little as 1 minute.
- ACTIVE COOLING SYSTEM: The upgraded cooling system prolongs inflation time so you can inflate 8 paddleboards in a row before triggering the overheating protection. This feature is especially important during hot summer days, making it perfect for family and group use.
- REAL-TIME MONITORING & AUTO-OFF FUNCTION: Simply set it to the desired PSI and, your Seawolf pump will monitor the real-time pressure and temperature automatically. The pump will shut off when the desired value is reached so you can get your other stuff ready. The automatic deflation function will make sure your paddle board is easy to roll up and pack after use. Inflate and deflate in minutes - without the hassle!
- WIDE RANGE OF USE: With a full set of 6 different-sized nozzles, the Seawolf electric pump can be used with any type of inflatables! Whether you're inflating a paddle board, kayak, towable tube, raft, or air mattress, this pump has you covered.
- SATISFACTION GUARANTEE: We understand the importance of quality products and stand behind our paddle board pump with a 1-year limited warranty. If you have any issues with our product simply send us a message any time for kind support.

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.

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.

I rarely write a review, but WOW! This is worth every penny. I've envied my friends with the electric paddle board pump, and after heavy research, I purchased this one. Here's the rundown: -easy to use, instructions easy to understand -quick inflation: 7 1/2 min for a 10.5ft board and just over 8 1/2 min for an 11.5ft board to 15PSI -Great battery life: I fully inflated and deflated 2 paddleboards and still had 75% battery life. I'm confident being able to inflate 4-5 boards in a row when I take a group out to the lake. -easy auto shutoff -convenient carrying bag, and I like that it comes with two types of charging cords The only thing to note is that this thing is loud. The first stage is quiet, about the volume of an air mattress pump. The second stage, which kicks in just below half a PSI (so about 1.5 minutes into inflating) is basically an air compressor and sounds as loud as my 2.5gal air compressor. I expected this so it's not a problem for me, but keep this in mind that any pump of this nature will be loud.

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.

Super fast, lots of hook-up options, has lasted several fulls without needing a charge. Love the colors. It is super loud, but I knew that going in.

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.

Time saver for sure, and saves your arms from hand pumping! Works great, inflating my SUP. Done in about 5 minutes! Deflated just as easy. Highly recommend!

High quality product. The pump inflates my board to 18 PSI in approximately 5 minutes. I use it in direct sunlight in temperatures around 93°F, and it has never overheated or shut down due to temperature. The auto shut off works as it should. I store and use the pump with about half charge in order to prolong the battery chemistry. This charge state is more than adequate for inflating a 229 Liter board multiple times. There are a plethora of inflation adapters on the hose however, I only use the Halkey-Roberts (HR) valve adapter. It is durable and does not leak, as well as hooking and unhooking smoothly.
