OutdoorMaster Shark 2S 88.8Wh Electric Paddle Board Pump
Product description
What it is
The OutdoorMaster Shark 2S is an electric paddle board pump designed to inflate and deflate a variety of inflatables, especially stand-up paddle boards. It runs on an 88.8Wh rechargeable battery and can handle up to 20 PSI with an auto-off feature to prevent over-inflation.
The essentials

On paper, the Shark 2S stands out for its two-in-one inflation and deflation capability, a 2-hour full charge via Type-C fast charging, and the option to power up from a car DC outlet (12V/15.8V). It also includes 8 nozzles to fit a wide range of inflatables—from SUPs to air beds and tents. A real-world benefit: you can inflate a paddle board to the target pressure and let the pump shut off automatically, which reduces guesswork and keeps gear from overinflating.
What stands out in use


In practical use, the pump can inflate a 10.6-foot SUP up to 15 PSI in a typical setup, and it can deflate efficiently to speed up packing. The real-time pressure readout helps you monitor progress and adjust on the fly. The 88.8Wh battery means you’re less likely to drain your car’s power or scramble for an outlet during a beach day. The USB-C/12V charging options expand flexibility for travel, camping trips, or family trips where outlets are scarce.

Pros and potential drawbacks
- Pros: convenient 2-in-1 inflation/deflation, digital pressure display, auto-off at target psi, multiple nozzles for versatility, Type-C fast charging, car power option, stands up to multiple boards per charge.
- Cons/limitations: performance depends on board size and desired psi, if you need higher psi consistently or heavier inflatables, you may notice longer inflate times. The battery life is adequate for several boards but not infinite, so plan charging on long days.
Who it’s for

This pump is well-suited for families or groups that own multiple inflatables or tighter pack-up routines at the beach. If you value a simple, all-in-one tool that reduces setup time and wants the option to power from a car, this model fits the bill.


Who it isn’t the best for
If your inflatables require consistently higher pressures or you’re aiming for very rapid inflation across many boards back-to-back, you might want a higher-capacity solution. It also may not be ideal if you need ultra-compact, ultra-light gear for backpacking trips.

When it makes sense to buy
Consider the Shark 2S if you routinely inflate/deflate up to 6 SUPs on a single outing, want a built-in deflation function, and value a battery-powered option with flexible charging. It’s especially practical for beach days, family trips, or setups where outlets aren’t always nearby.
What to review before purchasing



- Check your typical inflatables’ size and the required PSI to gauge inflation time with the 20 PSI limit.
- Confirm how often you’ll need to inflate multiple boards in a session to estimate battery sufficiency.
- Plan where you’ll charge: Type-C charging at home, or use a vehicle DC port when on the road.
How it compares to the broader approach
If you’re choosing between a battery-powered pump and a traditional wall-powered pump, the Shark 2S trades some peak speed for portability and independence from outlets. It’s a sensible middle ground for casual or semi-regular paddling rather than a professional, all-day inflator.

Final buying verdict
Final verdict
It’s a practical, versatile tool for mixed inflatable setups where independence from outlets and the ability to handle several boards in one session matter. It won’t replace a high-volume, heavy-duty pump for commercial use, but for family paddling and weekend adventures, it offers a balanced mix of convenience and capability. If you prioritize flexibility and built-in deflation, the Shark 2S is worth considering.
