Carrying case

The carrying case can be used as a carrying case for the electric hydrofoil surfboard. Designed with detachable wheels and special straps, this carrying case allows users to carry a complete set of Hobbywing eFoil-1 products. Users can put the power system, battery, remote control, hydrofoil, etc. into the carrying case and fix the board outside the carrying case. The inner lining of the box is made of EPP material, and the split compartment design avoids damage caused by extrusion and friction between the modules. At the same time, the board body alone avoids the collision and friction between the board body and the portable case.

Steps of use

Press the button on the socket to separate the straps to open the case
Remove the charger from the case and you can place the battery in the charger compartment. Place the back wing under the power supply. Place the front wing on the lid of the carrying case, make sure it clicks into place, then attach the straps.
