Swonder Seawolf Paddle Board Pump, 30% Faster 20 PSI SUP Electric Air Pump w/Dual Cylinder, Dual Stage & Active Cooling System, Supports 4 SUPs in a Row, 3 Colors Option

This seems to be a pretty good SUP inflator. I've only used it twice so far, just to try it out. My tests were done on my 11'6" SUP. The first test started out great, the inflation was up to about 7 psi...then I noticed the input voltage had dropped to 10.9volts...my engine was off. So I aborted the test and deflated my paddle board. I started my truck and restarted the test. Within 2 mins, the board was at 1.5PSI with the first stage pump. Then it automatically switched to the second stage...the sound changed from your standard air mattress inflator to a mini air compressor, nothing obnoxiously loud. Within 6 mins the Swonder Inflator shut off at the set 13psi. Wow! That was quick. Last weekend at the creek, a friend had a much cheaper 12v compressor that took well over 15 mins to fill their 10' SUP. I normally use an adapter to fill up my paddle board using my shop compressor in the past and the Swonder 12V compressor is faster! And more convenient! The Swonder 12v compressor will be my normal mode for now on. I can't give a review on durability yet, but don't forsee any problems. I'll update my review if needed.

I have 3 very large inflatable paddle boards, 2 of the 12' Isle Megalodon's and 1 of the Isle 15' Megalodon's. It's 15'X56"X8" with a volume of 1081 liters, it's huge! I've tried several high end, high pressure, pumps that all claimed to have active cooling and the ability to inflate several boards in a row. I tried using 2 of the Ventus pumps and also 2 of the Outdoor Master pumps. While those pumps are excellent and would serve you well with inflatables of less volume, and while they would handle inflating 1 of the 12' Megalodon's, and then require a cool down period of approximately 20 min, they simply weren't up to the task at hand of inflating either the 2 -12' boards or the 15' board without over heating. I could inflate 1 of the 12' boards and then I'd have to wait 20 min for the pump to cool off enough to operate again. And this was using 2 pumps simultaneously, 1 of them would over heat every time, even in the shade.Not the case at all with these Swonder Seawolf high pressure pumps! They are awesome! They claim to be 30% faster and that claim is legit! 2 of them running simultaneously will fill that 15' board in 16-17 minutes! To give a comparison, the Outdoor Master pump, using 2 simultaneously, would take 46 plus minutes, that's 37% faster! They didn't overheat and they also seem to be more accurate because both pumps would reach the set psi and automatically shut off withing a few seconds of each other, that was not the case with the other 2 brands.Buy this pump, you won't regret it!

This pump works really good. The only reason for 4 stars is that it’s quite large compared to other pumps. It still takes about 8-10 minutes to fill up each board. I filled up 3 boards and the pump never even got warm in 90 degree weather.

To be fair, we've only used this twice, but I'm really pleased with the results. My husband and I are new to the ISUP game and I did a bunch of research on electric inflators. This one wasn't always highest rated on the blogs, but consistently rated as fastest. We live in the desert southwest and it's over 100°. Fast is important! Our SUPs only have to inflate to 13 lbs and we did both of them in 11 minutes. Nice!The cord is long enough to reach in front of the car which is why I included that photo. As others have mentioned, a carrying case would be nice, but don't let that be a deal breaker.

So far so good. Pumped up my two Roc paddleboards to 15 psi and six Intex River Run tubes on a camping trip last weekend with no problems. Even helped out a couple looking to fill their two giant air beds. Saved them a 20 mile drive home to get the pump they forgot. And today it inflated my granddaughters 6'x10' three tube inflatable swimming pool. It can be loud(ish), like most pumps, when running on high but small price to pay for the ease of use. Has all the attachments I needed too. Note, it has only the cigarette lighter end for use with a vehicle. I used it with a Jackery 1000 to inflate the pool.

Based upon the reviews I expected a good product...at least one that did what it was supposed to do. Don't believe it. This pump does not work as advertised. It would pump my board to 8 pounds pressure, but no more before it would cut out and stop. And, it took 15 minutes to get that much pressure in the board. the advertised ability to pump a board to 20 pounds in 7 minutes is a fantasy. I cannot recommend this pump. Fortunately, I am within the 30 day return window and it IS going back.UPDATE: since the above was written, Swonder initiated contact with me regarding the performance of the pump. Even though I had already sent the original pump back and been credited for it, they sent me a replacement pump without charge, which I thought was gracious and I commend them for their service. However, the replacement pump did not work for me either. Into a 10'6" long SUP, it inflated the SUP from 1 to 6 PSI in four minutes, which I thought was outstanding and boded well for the replacement pump. However, at the 11 minute mark it had inflated to only 6.83 PSI, and at the 15 minute mark had inflated to only 6.89 PSI. At that point, not seeing any reason to continue with the experiment, it was discontinued and this pump had to be marked as a failure. Using the same board and the same inflator hose, I used another SUP pump [QTree]. It inflated the board from 0 to 6 PSI in 2 minutes, 40 seconds and 10 PSI in 10 minutes. it reached 10.7 PSI in 15 minutes, 13.1 PSI in 20 minutes, and the target pressure of 14.5 PSI in 25 minutes. So, the Qtree was slower than advertised, but at least it reached the target pressure eventually. I am sorry the Swonder pump was a fail, at least for me, because their customer service tried to make it right, and I again commend them for that service. Unfortunately, the one star review must remain based upon my experience.

Much quieter than some that I've heard. It does the job and does it quickly. I recommend it
