Shore Power

Marine Shore Power Cords, Adapters & Electrical Connections

Reliable shore power keeps your batteries charged, appliances running, and onboard electrical systems powered while your boat is at the dock. CritPro offers marine shore power cords, adapters, plugs, inlets, and accessories built to withstand harsh marine environments as part of our complete boating selection.

What to Look for in Shore Power Equipment

The most important consideration is matching the amperage and voltage of your boat and marina. Most recreational boats use either 30-amp or 50-amp shore power systems. Using the correct cord, inlet, and adapter helps prevent overheating, voltage drop, and damage to your boat's electrical system.

Look for marine-grade components with corrosion-resistant contacts, weatherproof construction, and locking connections that remain secure in rough conditions. Premium shore power equipment is designed to provide dependable dockside power while standing up to years of exposure to moisture and saltwater.
