Swonder Seawolf Paddle Board Pump w/ 9000mAh Battery Powered, 2X Quicker 20 PSI SUP Electrical Air Pump w/Twin Cylinders, Twin Stage, Lively Cooling System for Inflatable Paddleboard, Kayak

Perfect pump for my Retrospec Weekender Inflatable SUP
The hand pump that came with my SUP was way too much work. I switched to the Swonder Seawolf pump and couldn’t be happier. Once I figured out which nozzle to use, it fit on my SUP perfectly. It takes around 7 minutes to fully inflate to 12 PSI, then automatically shuts off. I love that I don’t have to plug it into my car. I haven’t tried to inflate more than one board at a time so I don’t know its capacity, but it works great for a single board.

WOW!!! GAME CHANGER!!!
For those of you with a lesser attention span, the Swonder Seawolf pump is an excellent pump, worthy of a 5-star rating and outperforming its competitors in cost, speed, capacity, PSI, and style. For those of you interested in an unbiased thorough review, read on.Due to my prior pump malfunctioning, I started out this season using a manual pump. I thought manual pumping would simply give me a better workout. While it certainly accomplishes that, it takes away from time preparing, precious time on the water, and a rather sweaty experience. This led me to explore my options. I knew this time around I wanted a fully portable pump.Fortunately, I came across the Swonder Seawolf and was intrigued by their Kickstarter campaign and its success. While other fully portable options are available, they fall short in a number of areas including battery capacity, pumping speed, or maximum PSI.Unlike many other SUP pumps, the Seawolf comes in a variety of color options: Black/Red, Cyan/Tangerine, and Lemon/Olive. Of course this is in no way indicative of performance, but a nice option to have. Furthermore, the pump is backed by a 1-year warranty.The company touts some impressive claims, like being 30% faster and the ability to pump up to 8 boards on a single charge. Having the backing of Amazon and a company satisfaction guarantee, I wanted to put these claims to the test.To begin, my board is larger than the standard with a greater volume: 12’6 x 32” x 6” with volume of 259 liters. Furthermore, I generally inflate my board to 17 PSI due to extra weight on board such as another individual and dog.On a single charge, I was able to get a full 5 inflations to 17 PSI, not to mention deflations over the course of a week. The time to inflation was pretty impressive. Using a stopwatch app, I noted the time to 15 PSI as well as 17 PSI. Time did wane in tandem with battery charge, as expected. Pumping to 15 PSI ranged from 8 minutes 15 seconds on a full charge to 10 minutes 36 seconds when nearly depleted, while pumping to 17 PSI ranged from 10 minutes 35 seconds to 12 minutes 50 seconds. A sixth attempt at inflation was unsuccessful, resulting in less than half the required PSI. During my week of tests, the weather was fairly warm, 80 Fahrenheit or more, and the pump was also left in the car while out on the board for 2 plus hours.In conclusion, the Swonder Seawolf is a game changer that exceeded my expectations and I could honestly recommend to anyone in the market for a pump.

Game changer!
This filled my board up to 15.5 psi in under 8 minutes. The battery still had full bars. Once it hits one psi the secondary pump kicks on and it is pretty loud. Some of the places I go people will be “sensitive” to the loud sound early in the morning. Mostly that will cause issue in places around San Diego where people are living the van life down by the beach. Wake up!Why is it a game changer? I can take my little kids with me and I don’t have to spend 45+ mins pumping up 2-3 boards! This pump is portable and fast. It is easy to use and that means I will use my boards even more!My pump had been obviously purchased prior and returned when I opened it up. No worries all worked fine and still seemed new.

This pump is easily transportable, easy and relatively intuitive to use. From a full charge, I can inflate and deflate three full-sized stand up paddleboards and still have charge left. It is easily transportable with the built-in handle.Changing the attachment is relatively easy, although the plastic link that holds the pieces together is pretty short, so it is sometimes tricky trying to get the attachment to where you want it. In addition to a stand up paddleboard attachment, there are also attachments that will fit pretty much every other inflatable device you might want to use.There only two downsides, and they are minor. The first is that the charging is long. You are talking a couple of hours to fully charge it. Plug it in overnight and you will be good to go. The other is the lack of a carrying bag. It would be nice to have a carrying bag/case that I could throw the pump and hose in to transport it.

My pump stopped working properly.It work on low mode up to about .75 psiWhen the motor should kick into high mode ,it stops and turns off.Only used it a handful of time. Maybe 5 times to pump two boards each time.
