Shop SmartPlug, a safer shore power connection. SmartPlug shore power plugs and inlets are engineered to connect more securely and resist the overheating and corrosion that plague old twist-lock connectors, a smart safety upgrade for your boat's shore power.
A safer, more secure shore power connection
Traditional twist-lock shore power connectors are a known weak point, prone to overheating, corrosion, and loose connections that can cause failures and even fires, and SmartPlug was engineered to fix that. The SmartPlug system uses a redesigned plug and inlet with more contact surface, a secure locking mechanism, and a weather seal, giving a connection that stays tight, resists corrosion, and runs cooler than a twist-lock plug. For boaters who connect to dock power, upgrading to a SmartPlug shore power system is a real safety improvement, reducing the risk of the connector problems that cause shore power failures and fires. It is a smart upgrade for a safer, more reliable connection.
Choosing the right SmartPlug comes down to your amperage and system. Match the SmartPlug plug and inlet to your boat's shore power amperage, commonly 30 or 50 amp. The system includes both the boat inlet and the cordset plug, so consider upgrading both ends for the full benefit. Installation replaces your existing inlet and plug, so confirm fit and follow the wiring instructions or have it installed. Review the product details and your shore power system before buying. With a SmartPlug system, you get a safer, more secure shore power connection.
