Buying advice

When choosing a shore power cord, consider the length needed for your dock setup, the amperage (usually 30A or 50A), and the cord's jacket material (EPDM is best for UV/marine environments). Look for molded connectors and twist-lock features for secure connections. If you're in an area with extreme weather, prioritize durability and flexibility. For budget buyers, shorter cords or PVC jackets can work, but expect shorter lifespan.
