SmartPlug Combo Kit
A four-point locking system secures the device.
The SmartPlug Combo Kit includes a 30-amp, 125-volt AC shore-power cord connector and a boatside inlet. This connector provides less electrical resistance, reducing the potential for arcing and overheating, SmartPlug says. Unlike a twist-type connector, there is no L blade to orientate. The connector is asymmetrical, so it can be pushed in with one hand; this is especially convenient when docking at night. Weatherproof seals help eliminate water penetration, and a four-point locking system secures the device, so there’s no need to thread a ring. The inlet cover is offered in stainless steel, or nonmetallic white, gray or black. $235; smartplug.com
