Blue Sea 4366 USB Panel with Circuit Breaker

The Blue Sea Systems 4366 is a water-resistant panel with a 15A breaker switch, a 12V socket, one dual USB charger and a mini voltmeter.

One charger and a voltmeter is the trade this model makes, against the 4368 which fits two chargers and a voltmeter in the same position. For a helm where knowing bank voltage matters more than a third and fourth USB port, this is the configuration that fits.

The illuminated Carling Technologies 15A breaker switch shuts the whole panel down. USB chargers pull current whenever they are powered, so on a boat left on a mooring that draw continues with nothing plugged in and nobody aboard.

Combining a socket, USB and a voltmeter in one position keeps the cutout count down on a crowded helm. Each separate fitting means another hole, another seal and another wiring run behind the panel. Explore more marine circuit breakers.
