Design & Build Quality

The OutdoorMaster Shark 3 features a compact, functional design that’s built for portability and performance. The rechargeable battery housing is compact enough to carry with your paddle board gear, while the 74Wh battery provides enough power for multiple boards.

The auto-off function is a key feature, allowing you to set your target pressure and let the pump do the work. The digital display shows the current and target pressure, so you always know where you stand. The 8 included nozzles ensure compatibility with a wide range of valves, from the standard Halkey-Roberts valve used on most SUPs to valves for kayaks, boats, and other inflatables. The durable construction ensures the pump holds up to regular use.

Performance

In real-world use, the OutdoorMaster Shark 3 excels in battery capacity and inflation speed. The 74Wh battery delivers on its promise of up to 4 SUPs per charge—a significant advantage over smaller batteries that handle only 1–2 boards. The 3’50” inflation time means you can get a board to full pressure in under 4 minutes, making group setup remarkably fast.

The 20 PSI capacity easily handles the 12–15 PSI most inflatable SUPs require for rigidity. The auto-off function means you can set it and walk away—no need to monitor the gauge or worry about over-inflation. The dual DC input (12V/15.8V) adds flexibility, letting you recharge or power the pump from your car or a compatible power source. For families or group paddlers, this pump simplifies your routine and gets everyone on the water faster.

Can One Charge Really Handle 4 SUPs?

The 74Wh battery is what makes the 4-SUP claim possible. Here’s how it breaks down:

• Standard 10’6″ SUP inflated to 15 PSI typically uses about 15–20Wh of battery power.
• With 74Wh of capacity, that translates to roughly 3–4 boards per charge, depending on board size, target pressure, and temperature.
• Larger boards (11′ or 12′) or higher pressures will use more battery per board, potentially reducing the total to 3 boards.
• Smaller boards or lower pressures may allow 4+ boards per charge.

The claim is realistic for standard-sized boards at 15 PSI, but actual results will vary based on board size, pressure, and conditions. For most families with standard 10’6″ boards, 3–4 boards per charge is achievable.
