You already own an electric pump with a 12V Car Plug to pump up your board, but the car park is a long hike away from the beach? This battery which weighs only 800 grams allows you to carry all your gear in the backpack and inflate your board where you will use it, by the water's edge. Easy operation with enough capacity to inflate 2 boards of up to 360 litres up to 20psi.
