SmartPlug B50ASSYPG Combo Kit With Female Connector
Best for: RVs and boats needing a reliable 50 amp inlet with enhanced contact area. This kit provides 20x more contact surface than twist-type designs, helping loads stay cool and stable. The body only fits one way, reducing the risk of wrong insertion, even in low-light conditions. Side clips lock the inlet to prevent movement. Suitable for combined marine shore power and campground hookups, it eliminates the need for separate parts. Caution: ensure the inlet matches your cord configuration and local shore power standards.
SmartPlug B50ASSYPW Combo Kit With White Non-Metallic Inlet
Best for: RVs and boats requiring a clean white, non-metallic option with the same high-contact advantage. Like the gray variant, it uses a large contact surface to prevent overheating and features a one-way body to avoid wrong connections in the dark. Side clips secure the inlet, maintaining stability as cords move. Choose this if you prefer a lighter, white unit that matches other shore-power equipment. Limitation: color choice may affect visibility on certain docks or storage areas.
SMARTPLUG BF50 Boatside Connector
Best for: Boat owners needing a versatile 50 amp connector usable with either 125V or 250V service. The design emphasizes ease of use in dark or awkward locations, with 20x more contact surface for reduced overheating. This option is well-suited for marine shore power setups. Limitation: compatibility with non-standard marina power configurations should be verified before use.
SmartPlug B50ASSYPB Shore Power Inlet & Connector
Best for: RVs and boats needing a weatherproof, heavy-duty inlet with a push-in design. It shares the same multi-point locking system and offset lighting benefits to help avoid pin stress during movement. Side clips lock the inlet for stability. Caution: check the inlet cover and gasket condition periodically to maintain weatherproof performance.
SmartPlug BM50S Boat Side Inlet
Best for: Boaters seeking a robust 50 amp inlet with a multi-point locking system that minimizes stress on pins from cord movement. The increased contact area improves conductivity under high amperage demand. It’s designed for marine applications and for shore power setups. Limitation: compatibility with non-standard dock power layouts should be confirmed beforehand.
Buying Guide: Key Purchase Considerations
- What service voltage do I need? Look for 125V/250V compatibility to cover marina or campground setups.
- Is locking and orientation important? Choose multi-point locking and a one-way body design to prevent accidental misinsertion.
- Do I need marine-grade weatherproofing? Weather seals and gaskets help prevent moisture intrusion in outdoor or wet environments.
- Will the unit be used in low-light conditions? Insertion reliability and visible indicators help reduce misplugging in the dark.
- What is the cord movement risk? Choose models with side clips and secure inlets to minimize stress on contacts when cords shift.
- Compatibility with existing gear? Confirm that the inlet type and connector match your shore power equipment, boat, or RV.
Practical considerations
- Materials: non-metallic vs metal inlets—choose based on corrosion resistance and environment.
- Locking mechanism: locking plugs minimize accidental disconnection during movement.
- Maintenance: inspect gaskets and contact surfaces for wear and corrosion.
- Installation: ensure correct wiring and adherence to electrical safety standards when mounting or replacing inlets.
