The All New Genius.

Better Performance.

The NOCO GENIUS2X4 Next To The Previous NOCO G4

Powerful, Efficient, and Compact.

The Next Generation

Compact, yet powerful battery charger. A mix of electrical engineering and industrial design pack a powerful battery charger into a tiny footprint. The GENIUS2X2 uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging. And its onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.

Multi-Voltage. Multi-Chemistry. Multi-Battery Type.

Do More With One Charger

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).

Improved Start Voltage Sensor. All-New Force Mode.

Charge Dead Batteries.

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 -4F and avoids over-charging in hot weather up to 104F.

Bring Batteries Back to Life

The GENIUS2X4 automatically detects sulfation/acid stratification. If any is found, the GENIUS2X4 will automatically repair and reverse the damage done to the battery, extending the usable life and increasing the performance.
