OutdoorMaster Shark 20PSI High Pressure SUP Air Pump – Intelligent Dual Stage Inflation with Auto-Off
Product description
What it is and what it solves
The OutdoorMaster Shark pump is a 12V DC car-powered, high‑pressure air pump designed for inflatable stand‑up paddle boards and other high‑pressure inflatables. It aims to simplify inflating to a precise pressure (up to 20 psi) with a compact, integrated solution that combines speed, accuracy and ease of use in one unit.
How it works in practice

This pump uses a dual‑stage design: the first stage focuses on rapid inflation at up to 350 L/min, while the second stage tightens the final pressure up to 70 L/min for steady, controlled inflation. An automatic shut‑off feature stops the pump when the target pressure is reached, helping avoid over‑inflation. When you’re packing away, the built‑in deflation function makes the process quicker and less fiddly.
Key points to note


A few practical details help it fit into real-world kit: it plugs into a 12V DC car socket, has a dedicated 12A fuse for safety, and ships with a full set of nozzles to cover common high‑pressure valves such as C7 and H3. Real‑time pressure is visible on the supplied digital display, so you can monitor progress without guesswork.

What stands out in use
The included active cooling system is a notable feature, designed to keep the unit from overheating during consecutive inflations. This is particularly useful if you’re pumping multiple boards in a single session or using the pump on a windy, hot day. The Shark’s design also prioritises a straightforward setup—just connect to your car’s power, choose your target psi, and let the pump do the work while you prepare the board.
Pros and cons at a glance

Pros: fast initial inflation, precise final pressure thanks to auto‑off, active cooling for extended use, flexible nozzle kit, real‑time pressure readout, deflation for quick pack‑down, safe 12A fuse. Cons: performance is strongly tied to a 12V car power source, so using it away from a vehicle may require alternative power arrangements, the 20 psi ceiling is standard for many SUP boards but may not suit extremely high‑pressure inflatables.


Who it’s for
If you frequently travel with SUP boards, boats or other inflatables and value a fairly compact, auto‑metered inflator with a safety shut‑off, this pump can be a sensible choice. It’s particularly appealing for multi‑board sessions thanks to cooling and the rapid‑start capability. It may suit buyers who prioritise convenience over ultralight portability or sheer maximum power.

When it might not be the best option
Not ideal if you often inflate away from a vehicle or if you need higher pressures beyond 20 psi. If you rely on battery power or a mains charger rather than a car socket, this unit won’t be as flexible. If you already own a pump with slower inflation and no auto‑off, you’ll notice the difference in setup simplicity and final accuracy.
What to check before buying



- Confirm your boards require up to 20 psi and are compatible with C7/H3 valve fittings supplied.
- Consider your typical inflate/deflate workflow—auto‑off is convenient, but ensure you’re comfortable setting the target pressure on the display.
- If you’re inflating multiple boards back‑to‑back, the active cooling feature is worth testing in real‑world conditions.
Practical use example
Imagine a weekend trip where you need to set up two SUP boards and a small dinghy. You connect the Shark to the car, attach the nozzles, set the target psi for each board, and watch the display as it inflates quickly, then stops precisely at the mark. When it’s time to pack, you switch to deflate mode and have the boards ready to stow in minutes without guessing the right pressure.

FAQ (based on available data)
- Can I pump without a car? The unit is designed for 12V DC car power, other power sources aren’t specified.
- What valves are supported? It includes nozzles for C7 and H3 valves.
- Does it show real‑time pressure? Yes, via a digital display.
- Is there a warranty? The product comes with one year of after‑sales service.
Final buy‑or‑not decision
Is it worth it? It makes sense if you value controlled, repeatable inflation with automatic cut‑off and a cooling system for multiple boards in a single session. It’s a practical option for frequent SUP users who want to streamline setup and takedown, provided you’ll predominantly use it with a 12V vehicle power source.
