The Outdoor Master Shark 3 is the latest model electric SUP pump that is an upgrade from the popular Shark Series. We know the popular version 1 and 2 are known as some of the best electric paddle board pumps are so we had to test these as soon as they came onto the market. These pumps make it easy to inflate your inflatables and we had to see how good they really are. 

 

This one is powerful and convenient, making it an excellent rechargeable paddle board pump for individuals who want to save time and energy. 

 

We’ve spoken to various enthusiasts and paddle boarders to get their opinion on this one and see if the additional upgrades are worth the hype. 

Overview of Outdoor Master Shark 3 Electric Pump

Outdoor Master has featured in various articles on here and if you are a regular reader, then you will know that we think it is a top brand in the electric stand-up paddleboard (SUP) pump market. They focus on innovation, durability, and user-friendly designs.

 

Many electric SUP pumps can be slow in our opinion, with frustrating users who often opt for manual pumps to save time, even if it requires more effort. Outdoor Master changes this with the Shark 3 battery-powered electric pump. This pump is fast and efficient for inflating inflatable stand-up paddleboards (iSUPs).

 

The Shark 3 is not only quick, but it also has an integrated battery, operates quietly, and offers multiple settings. It is versatile enough to inflate various items, including kite wings and camping mattresses.

  • Maximum Pressure: 20 PSI

  • Handle & Storage: Built-in nylon strap and storage bag

Build & Size

The Shark 3 has dimensions of 13 x 7.5 x 7 inches and weighs 6.4 pounds, making it significantly larger and heavier than our Airbank Puffer Pro but not as heavy as the Topump TPS300. Despite its size, the Shark 3 excels in performance, demonstrating exceptional stability and efficiency.

 

Moreover, its strong construction uses high-quality materials that enhance durability, ensuring it can withstand the demands of frequent outdoor adventures. This makes it a reliable companion for any outdoor enthusiast.

Connectivity & Ports

On the front, the pump features both inflation and deflation ports for versatile use. A rubberized flap hides the charging ports:

  • USB-C port: Supports fast charging and also functions as a power output for mobile devices.
  • 12V DC input: Allows you to charge the pump from a car or external power source, and also enables direct operation of the pump when the internal battery is depleted.

The dual power capability is a real lifesaver when you forget to charge the battery before heading out to the water.

Accessories

The Shark 3 includes a 7-valve adapter set, allowing you to easily inflate various items, such as paddleboards, kayaks, and air mattresses. This feature enables you to complete various tasks without requiring additional attachments.

 

However, the pump does not come with a carrying bag, so it may be tricky to organize and transport the hose and cables. As a result, you might end up with tangles when storing the equipment after use.

Controls

The interface is straightforward, with a large LCD screen and easy-to-use buttons.

  • Selector Button: Switches between PSI and Bar units or cycles through the three inflation modes—SUP, KITE, and MAT.
  • + / - Buttons: Fine-tune the pressure in increments of 0.1 PSI for precise inflation.

The pump remembers your last used settings, saving time during repeated use.

LCD Screen

The screen provides clear readability when used indoors, displaying information without straining the eyes. However, under bright sunlight, visibility becomes challenging.

 

In such conditions, you often need to shield the screen with your hand to improve clarity and see the details more easily. This is definitely an area where Outdoor Master could consider enhancing the design for a more user-friendly experience outdoors.

Inflation Speed and Battery Life

The Shark 3’s two-stage dual-piston system is its star feature, combining speed with high-pressure performance.

Inflation Speed

  • Stage 1: High-flow, low-pressure mode that quickly fills the paddleboard to around 1 PSI.
  • Stage 2: Low-flow, high-pressure mode that takes over to reach your set pressure (up to 20 PSI).

In our tests, the Shark 3 inflated an 11' x 32" x 6" all-around inflatable stand-up paddleboard (iSUP) to 15 PSI in just 4 minutes and 44 seconds. Even after four full inflations, the time only increased slightly to about 5 minutes and 30 seconds. This pump can fully inflate four boards on a single charge, which is better than most competitors that can only inflate 2 or 3 boards per charge.

 

If the internal battery runs out, connect the 12V adapter. The pump will operate more slowly, taking approximately 11 minutes to complete the same task, but it will still accomplish the task.

Noise Levels

The Shark 3 pump delivers exceptionally smooth and quiet operation, surpassing the performance of many conventional electric pumps that often produce a harsh, mechanical sound. 

 

With a noise level of around 89 dB, it's not entirely silent, but the sound it generates is tolerable. Notably, during the second stage of operation, the noise becomes less intrusive, allowing for a more peaceful experience while using the pump.

Warranty and Customer Support

Outdoor Master offers a 2-year warranty, one of the longest in this price range for electric pumps. This shows they stand behind the quality and durability of their products. They also offer a 30-day return policy, allowing you to return the product if you are not satisfied.

 

If you need replacement parts, such as hoses or valve adapters, you can easily find them on their user-friendly website. 

 

Outdoor Master values customer care and offers support through email, phone, and social media. They are known for their quick and helpful responses. This combination of quality and excellent service makes Outdoor Master a great choice for outdoor enthusiasts.
