Outdoor Master Shark 2 (Shark II) — 20 PSI Electric SUP Pump

Skip the car-park workout. Plug the Shark 2 into your 12V socket, set the PSI, and let the dual-stage motor take your board to an accurate 20 PSI. Every inflation reaches full pressure and stops automatically at your set target.

What makes this pump good

• Dual-stage motor - high-volume fill, then high-pressure finish to reach 18–20 PSI reliably.
• Active cooling - manages motor temperature for consecutive inflations without thermal cut-outs.
• Set-and-stop control - digital pressure selection in 0.1 PSI steps with auto shut-off at the pressure you choose.
• Inflate and deflate - one unit handles setup and pack-down.
• 12V vehicle power - straightforward power from your car, van or battery pack.
• Certified for UK use - CE, UKCA, RoHS, REACH, WEEE.

Real-world performance

A typical 10’6″ - 11′0 Allround iSUP (~240–260 L) reaches 18–20 PSI in roughly eight to nine minutes from flat when powered by a 12V vehicle socket. The pump inflates efficiently using the latest technology and automatically stops at the set PSI. Switch to deflate to remove residual air for a neater roll-up.

FAQ

Can it run from mains power?

It’s designed for 12V sockets. A regulated 12V power supply or power station is suitable if it provides at least 10 A continuously.

How many boards can it inflate in sequence?

The active cooling system supports up to three back-to-back inflations without thermal cut-outs.

Will it over-inflate?

No. The pump stops automatically at the set pressure.
