You recently purchased an iSUP, or you’re an old hand in the game. You love the convenience, and compact nature inflatable boards afford you, but one thing usually holds you back from going out on the water with enthusiasm, and that’s having to pump them up manually.
That’s why you’re here right!
To determine if the Outdoor Master SHARK II (Official Name: OP20 SHARK) is worth the investment.
While you may have initially taken manual pumping in your stride, there’s no doubt that even if you don’t get exhausted by doing it, your back doesn’t necessarily enjoy the experience.
I, too, had no idea how leisurely pumping your SUP could be until the guys at Outdoor Master sent me their best-selling electric pump to try out for myself.

What Comes In The SHARK II Electric SUP Pump Box
This e-pump is ready to go out of the box straight away and comes with everything you need apart from a car which is the power source for this pump which may present an issue if you don’t own or have a vehicle you can borrow with a cigarette lighter plug-type connection.
And for those of you who want to see all the angles click on the images below:
Other than the obvious OP20 SHARK E-pump, the following accessories come in the package:
Five diffrent vale connections:
- one H3 valve, which will be used for most SUPs

- One C7 Valve
- One S2 Valve
- One Boston Valve
- One Pinch Valve
A hose that connects the valves between the SUP and the pump.
Most SUPs will use the H3 Connection valve, and this was the case with my GLIDE O2 Retro and SUPZOOM Shark SUP.

Is The SHARK II INtelegent DC E-Pump Easy To Use
I was pretty impressed by how easy it was to use the SHARK pump.
I literally screwed the H3 valve connection to the hose, attached the hose to the pump and then to the SUP, started the car, selected my desired PSI, pressed the ON button, and sat back and relaxed.
It’s worth noting that the pump will detect the current PSI level in your SUP or other inflatable devices.
The pump will also stop automatically when the desired PSI level is reached or when the pump reaches a point where further use would cause it to overheat.
Is the SHARK II E-Pump Sturdy
Before receiving the pump, I had doubts about whether it would be a bit flimsy, but those concerns were very quickly dispelled when I opened the package.
Unlike the manual pumps that arrived with my original SUPs, where I felt I had to be very gentle with all the connections and attachments, I had no such feeling with the pump or the equipment provided.
That’s not to say you should abuse them, but considering everything is made of plastic materials, the build quality is definitely good.
Is the PSI Gauge On The SHARK II Accurate?
After inflating both SUPs to different levels of PSI values, I then compared the reading on the pump with the reading from manual gauges, and they both matched on each occasion.
Were There Any Inflation Issues When Using The Shark II
If you read my original reviews of my GLIDE and SUPZOOM paddle boards, both had some inflation issues when using the provided manual pump, but those issues were not present when using the SHARk II electric pump. The gaskets and seals on the pump are very sturdy, and there was no air escape during the inflation process.
After use, I could not unscrew the H3 valve from the hose, but I used vice grips to gently separate the valve from the hose, which worked perfectly.
How Long Did The E-pump Take To Inflate The SUPs
It took the SHARK II 6.5 minutes to inflate my SUPZOOM paddle board to 12 PSI and just under 8 minutes to inflate my GLIDE paddle board to 15 PSI.
I can tell you from personal experience there is no way I would have been able to inflate two paddle boards by myself in under 15 minutes.
Tips For Using The SHARK II E-Pump.
TIP #1
Have everything set up before you start.
Take the time to read the instructions. It will take less than 5 minutes.
if you’re going to be pumping multiple paddle boards, this will make the whole process much simpler
Tip #2
Leave your car engine running while using the pump.
I’m not sure how long it would take to flatten your car’s battery as that would depend on many other factors, but it’s best not to find out.
It wouldn’t be very fun coming back to your car after a great SUP session only to find you have a flat battery.
Tip #3
Place the pump on your SUP during the inflation process.
It’s pretty hard to find an area with no small rocks, dirt, or sand when you are outdoors. The SHARK pump is so light, and placing it on your paddle board makes complete sense.
It means it stays upright, and the hose stays in the same relative position as the SUP during the whole inflation process. Plus, this ensures the pump doesn’t inadvertently suck up dirt or sand.
Our Verdict On The Outdoor Master OP20 SHARK E-Pump
Apart from having only a cigarette lighter plug as the power source, I couldn’t find any other issues with the SHARK II DC electric pump.
It worked perfectly and solved other inflation issues, which I could not overcome with the manual pumps provided by the manufacturers of my paddle boards.
I would highly recommend this pump to anyone who drives down to their favorite paddle boarding location and is able to inflate their SUP in an area close to their car in those locations.
