Product Details

The GENIUS5 delivers a powerful charging solution in a compact design that is 34% smaller and 65% more efficient than its predecessor, the G3500. It supports 6-volt and 12-volt lead-acid batteries (AGM, gel, flooded, deep-cycle) and lithium-ion (LiFePO4) batteries, covering a wide range of vehicles—including cars, motorcycles, ATVs, RVs, and more—up to 120 amp-hours. The charger features an integrated thermal sensor that adjusts the charging process based on ambient temperature, thus preventing overcharging in hot weather and undercharging in cold conditions. It can charge batteries as low as 1 volt and includes a Force Mode to recharge completely dead batteries down to zero volts. Additionally, precision pulse charging helps restore battery health by reversing sulfation and acid stratification, improving performance and extending battery life. The charger allows for safe, continuous connection for worry-free maintenance. The package contains a 5A charger (120-240VAC), a 72-inch AC cable, an 80-inch DC cable with battery clamps, integrated eyelet terminals, a mounting bracket, screws, and a three-year warranty. Designed proudly in the USA, the GENIUS5 combines power and reliability in a compact unit.
