2-Bank 4-Amp Battery Charger, Maintainer & Desulfator (NOCO GENIUS2X2)

Introducing the all-new GENIUS2X2, one of our most powerful, highest-performing, energy-efficient, and compact chargers yet. The GENIUS2X2 is a 6-volt and 12-volt two-bank battery charger, battery maintainer, trickle charger, and battery desulfator. It's rated at 4-amps (2-amps per bank) for all types of lead-acid and lithium-ion batteries, including flooded, gel, and AGM, as well as marine and deep-cycle batteries.

The All-New GENIUS: Smaller Size, More Power

Compared to the previous NOCO G1100 model, the all-new NOCO GENIUS2X2 delivers better performance while being 51% smaller in size and delivering over 53% more power.

The Next Generation: Powerful, Efficient, And Compact

A compact, yet powerful battery charger. A mix of electrical engineering and industrial design packs a powerful battery charger into a tiny footprint. The GENIUS2X2 uses high-frequency switch-mode technology to efficiently convert AC power into safe DC power for battery charging. Its onboard microcomputer precisely controls the charging to minimize power loss, creating an incredibly compact form factor.

Do More With One Charger: Multi-Voltage And Multi-Chemistry

A multi-functional design that allows you to charge in more ways. Effortlessly charge multiple battery voltages (6-volt and 12-volt lead-acid and lithium-ion batteries), chemistries (flooded, gel, maintenance-free and AGM batteries) and types (starter, deep-cycle, marine, powersport and more).

Charge Dead Batteries: Improved Sensor And All-New Force Mode

The all-new start-voltage sensor allows the GENIUS to detect and charge dead batteries as low as 1-volt. For extremely dead batteries lower than 1-volt, manually turn on Force Mode to detect and charge batteries all the way down to zero volts.

Thermal Compensation: More Precise Charging In Any Climate

The new integrated thermal sensor automatically monitors and adjusts the charging cycle based on fluctuations of ambient temperature, limiting the chance of under-charging or over-charging, providing a more accurate and fully charged battery. Avoids under-charging in cold weather down to -4°F (-20°C) and avoids over-charging in hot weather up to 104°F (40°C).

Bring Batteries Back To Life: Auto Detection And Auto Repair

The GENIUS2X2 automatically detects sulfation and acid stratification. If any is found, the GENIUS2X2 will automatically repair and reverse the damage done to the battery, extending its usable life and increasing performance.

Completely Automatic: Year-Round Charging And Zero Overcharge

Finally, a charger from start to finish that’s completely automatic. No special modes, no technical knowledge required. Genius will safely charge any battery. It detects damaged batteries and intuitively repairs them, and actively monitors for long-term battery maintenance to extend battery life. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.

Redesigned Clamps: Improved Clamping Range And Force

Genius clamps are built with needle-nose profiles for smaller terminal applications and detachable integrated eyelets for permanent mounting the accessory to the battery. Designed to fit battery terminals of any shape and size. Engineered for improved clamping range, clamping force, and higher conductivity.
