Sea-Dog Power Box 50-Amp Battery Switch Panel

The Sea-Dog Power Box combines battery switching, voltage monitoring, fused power distribution, and multiple accessory outputs in one compact unit for john boats, kayaks, and other small craft. A 50A battery switch controls the box, while an integrated LED voltmeter lets you monitor system voltage at a glance.

The enclosure includes two 12V power sockets, two Anderson-style outputs, one USB-C port, and four USB-A charging ports, giving you several ways to power or charge onboard accessories from one centralized location. An internal fuse block provides onboard circuit protection, and the switch uses a removable knob for added security.

The Power Box operates on 12-24V systems with a total output rating of 50A. An Anderson battery plug with terminals and four #8 flat-head mounting fasteners are included. For small-boat electrical systems that need organized switching, monitoring, and accessory power in one enclosure, this Sea-Dog Power Box provides a practical all-in-one solution. Worth comparing against our other battery switches.
