Introducing the GEN5X1, our toughest, most compact, and powerful onboard marine battery charger yet. Built to charge and maintain one (1) 12-volt lead-acid or lithium-ion battery—including flooded, gel, AGM, and deep-cycle types—it delivers 5-amps of pure charging power per bank. It also functions as a battery maintainer and desulfator. The package includes a GEN5X1 5-Amp 1-Bank Waterproof Onboard Marine Battery Charger (120-240VAC), self-tapping mounting screws, a user guide, and a 3-year warranty. Certified to UL1236, ISO 8846, and 33 CFR 183.410.

Meet the GEN5X1 – an upgraded version of our GENM1, now 37% smaller and 43% more powerful. It’s one of the best-performing onboard marine battery chargers we’ve ever built.
This 5-amp, 1-bank charger is designed for 12-volt batteries, including marine, boat, starter, and deep-cycle batteries. It features selectable charging modes (12V, 12V AGM, 12V Lithium, and 12V Repair Mode) to independently charge and control each battery bank, supporting both lead-acid and lithium-ion batteries.
Precision charging is ensured with an integrated thermal sensor that adjusts the charge based on ambient temperature, preventing over-charging in heat and under-charging in cold. It can charge batteries as low as 1-volt, with an optional force mode for manually charging dead batteries down to zero volts.
The simplified mounting system allows installation in any direction, even upside-down, with an anti-vibration backing to reduce shock, vibration, and noise. Fully sealed and waterproof (IP68 rated), it has endured rigorous testing, including thousands of hours underwater.
Included in the box: GEN5X1 5-amp 1-bank waterproof charger (120-240VAC), 72-inch DC cables with 3/8-inch eyelets, 72-inch Type-B AC cable, (2) self-tapping screws, user guide, and a 3-year warranty.
