Guest On-Board Battery Charger 8A / 12V - 2 Bank - 120V Input

The Guest On-Board Battery Charger 8A / 12V - 2 Bank - 120V Input is the reliable charging solution serious boaters and anglers depend on when they're away from the dock. Whether you're running dual battery systems for extended fishing trips, overnight expeditions, or auxiliary power for trolling motors and electronics, this two-bank charger ensures both batteries stay fully charged and ready. Guest has engineered this unit specifically for the demands of marine environments, where battery management directly impacts safety, navigation capability, and the performance of critical on-board systems.

This dual-bank charger delivers 8 amps of charging current per bank at 12 volts, allowing independent management of two separate battery circuits from a single 120V AC shore power input. The two-bank design means you can charge a starting battery and an auxiliary or house battery simultaneously without cross-interference, maximizing charging efficiency and reducing downtime between outings. Built to withstand the salt spray, vibration, and corrosive marine environment, Guest chargers feature solid construction and straightforward operation—no complex programming required. The compact footprint (10 x 6 x 13 inches) fits easily into engine compartments, cabin storage, or galley cabinets without consuming valuable deck space.

Anglers who maintain multiple battery banks for sonar, GPS, live wells, and auxiliary systems will find this charger indispensable for overnight dock charging or shore-based battery maintenance. It's equally valuable for cruisers, center-console operators, and pontoon owners who rely on consistent electrical power for safety lighting, communication gear, and entertainment systems. Installation requires only a standard 120V household outlet at the dock or marina—no hardwiring necessary for portable use. This charger works seamlessly with standard lead-acid and absorbed glass mat (AGM) batteries commonly found in modern marine vessels, making it compatible with virtually any recreational boat equipped with dual 12-volt systems.
