Abstract: The present disclosure provides that includes a power supply; a propulsion device and an adapter. The propulsion device includes a housing comprising an outer surface, a motor disposed within the housing and coupled to a propeller for generating propulsion forces for propelling the propulsion device; and an electrical connection on the outer surface of the housing and connected to the motor. The adapter comprises an electrical conduit extending between a first end and a second end of the adapter, the first end configured to couple to a support for the power supply and the second end configured to releasably attach to the outer surface of the housing of the propulsion device to form a watertight seal and to electrically connect, via the electrical conduit, the power supply to the electrical connection on the outer surface of the housing to supply power from the power supply to the motor.
