A waterproof power adapter, comprising:

• a waterproof housing enclosing an AC to DC converter having an AC power supply input and a DC power supply output;
• a fixed, waterproof AC power connection for coupling an external power supply to the AC power supply input;
• a female connector, a portion of the female connector coupled within the housing to the DC power supply output, and an exposed portion of the female connector configured to couple a DC power supply voltage provided at the DC power supply output to a complementary and separate male connector, the exposed portion being exposed to environmental conditions when not coupled to the male connector;
• a sealing structure configured to engage with a cover of the male connector in a sealed position to provide a waterproof environment around an electrical connection formed when the female connector is coupled to the male connector;
• and
• a locking mechanism configured to releasably tighten and lock the cover of the male connector in the sealed position when the female and the male connectors are coupled to one another, wherein the locking mechanism is arranged along an outer surface of the exposed portion of the female connector.
