Furrion 50-amp Cordset
$721.65 (50 feet, 125 volts); www.furrion.com
A 50-amp shorepower cord that lets boatowners know when they’ve got juice flowing properly into their boats will remove one source of stress. The cord uses two blue LED lights to indicate power is on, one on each of the cord’s 125-volt legs. Cord sets are available in 50- and 25-foot lengths. A 30-amp cord is available with two LEDs as well, but with different functions: One is a power indicator and the other shows a ground fault.
