By Jo MoseleyHands up, I didnt see the point of electric pumps for years. I was happy to inflate my board manually, considering it an integral part of the experience and often extolling its virtues for a good warm-up in winter. I didnt want to rely on being near a vehicle for the power source, especially if I travelled by train to a launch point.A few years into my SUP journey, I was given an electric pump and started using it whilst researching my second book, Stand Up Paddleboarding in the Lake District Beautiful Places to Paddleboard in Cumbria. It was handy but still not great it only pumped to 15psi, it was noisy, I had to be close to the car, and, in all honesty, it took a long time to inflate. I could get myself ready, but I still had to wait around for a while to get on the water.So when SUP Mag UK invited me to test and review the Shark 3 Rechargeable SUP Electric Pump, I was excited but also a little bit sceptical of the claims, which included fast pumping to 20 psi, including four paddleboards in a row (to 15 psi), the option to use it away from a vehicle, and that it acts as a power bank. It charges fully in two hours using a 45 W fast charger.It felt too good to be true!The Shark 3 Rechargeable Electric Air Pump can be used for iSUPs, mats, and kites. It has a battery 12 V DC power supply and eight versatile nozzles, making it compatible with other equipment, which could be very handy. Its a smart-looking piece of kit in black and orange with clear instructions for the inflation and deflation option and power points, which are protected, too. It comes with a clear instruction manual rather than relying solely on customers using a QR code online. Most importantly, it works! It really does inflate the board very quickly so much so that I inflated it twice in a row to the 20 psi I needed in case the first time was a fluke! Its a lot quieter than I am used to, as well. It can inflate for 35 minutes of continuous inflation without overheating.I would say it is larger than other pumps I have seen on the market and is heavier.The screen is clear in the shade, but it can be tricky to read in the bright sun.That said, I think this is a very impressive piece of kit, and I would recommend it, especially if you are a family or group of friends who want to inflate and get on the water as soon as possible. I have never used Outdoor Master Shark products before, but based on this pump, I would definitely look at other products in the future. I also stand 100% corrected on my opinion of electric pumps now, too!Preorder 135.28https://outdoormaster.com/products/shark-3-electric-sup-pump
