Boat owners, this RVMATE marine shore power cord is exactly what you need for reliable dock power. We're talking about a solid 50 feet of 10-gauge, 3-conductor cable that delivers 30 amps at 125 volts - plenty of power for running your boat's systems while docked. The heavy-duty construction features 100% copper wiring for maximum conductivity and a weather-resistant PVC jacket that stands up to sun, saltwater, and the general marine environment. The twist-lock NEMA L5-30 connectors at both ends ensure a secure connection that won't accidentally come loose, with a locking ring for extra safety. The female end even has a handy LED power indicator light so you can see at a glance when power is flowing.

The 10AWG thickness means minimal voltage drop over the full length, so your appliances and battery chargers get the consistent power they require.
