NOCO Genius GEN5X2: 2-Bank 10A Onboard Marine Charger | IP68 Waterproof

Meet the GEN5X2: compact power for dual batteries

The NOCO Genius GEN5X2 is a fully sealed, waterproof onboard charger designed to deliver a total of 10 amps, with 5 amps per bank. Built for 12-volt systems and compatible with a range of chemistries including flooded, AGM, gel, and LiFePO4, it fits tight spaces on boats without sacrificing power. Its refined, 37% smaller footprint compared to the GENM2 makes it a discreet yet capable partner for marine electrical setups, while still providing robust charging for two batteries at once.

Two independent banks, one cleared path to reliable power

Engineered to charge two banks independently, the GEN5X2 lets you monitor and maintain two batteries simultaneously, even if they’re of different types or states. This separation enables precise charging for each battery, reducing cross-interaction and helping you keep critical systems ready for use.

• Independent 5A per bank delivers up to 10A total
• Supports multiple battery chemistries on separate banks
• Simple, precise control without compromising the other battery

Smart, adaptable charging modes for versatile marine use

Each bank offers selectable modes to tailor charging to battery health and life. Choose from 12V, 12V AGM, 12V Lithium, or Repair Mode to address aging batteries or recovery needs. A built-in thermal sensor continuously adjusts charging as temperatures swing, helping to prevent overcharging in heat and undercharging in cold environments.

• 12V, AGM, and Lithium options per bank
• Repair Mode to nurture aging packs (where applicable)
• Thermal compensation for stable performance across climates

Power-on-demand for deeply discharged batteries

When a battery is very low, the GEN5X2 can start charging from as low as 1 volt. If a battery is completely flat, Force Mode allows you to manually begin charging from zero volts, offering a practical path to revive neglected packs and bring them back into service.

• Charge from 1 volt or zero volts with Force Mode
• Helpful for recovering neglected or poorly maintained batteries

Rugged design for harsh marine environments

Built to endure demanding conditions, the GEN5X2 carries an IP68 rating for waterproof protection and has undergone extensive life-cycle testing. Its mounting system is redesigned for fast, secure installation in any orientation, including upside down, with an integrated anti-vibration backing that minimizes shock and noise on deck.

• IP68 fully sealed enclosure
• Mounting flexibility, even upside down
• Anti-vibration backing reduces noise and wear
