Our Most Powerful, Efficient, and Compact Charger Yet.
Compact, yet powerful battery charger. A mix of electrical engineering and industrial design pack a powerful battery charger into a tiny footprint. The GENIUS2X4 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.
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.
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.
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.
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.
Year-Round Charging. Zero Overcharge. Auto Memory.
Finally a charger from start to finish that’s completely automatic. No special modes, no technical knowledge required. Genius will safely charge any battery. Detect damaged batteries and intuitively repair them. And actively monitor for long-term battery maintenance and extend battery life. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.
Improved Clamping Range. Improved Clamping Force.
Genius clamps are built with needle-nose profiles for smaller terminal applications and detachable integrated eyelets for permanent mounting the accessory to battery. Designed to fit battery terminals of any shape and size. Engineered for improved clamping range, clamping force, and higher conductivity.
