One Charger for ALL Your Batteries! The LiitoKala Lii-CH2 is a revolutionary dual-slot smart charger that eliminates the need for multiple charging devices. Featuring an upgraded universal compatibility system, it automatically detects and charges 1.5V Li-ion, 1.2V NiMH/NiCd, 3.2V LiFePO4, and 3.6V/3.7V Li-ion batteries with precision and safety.
Equipped with a modern USB Type-C input, the Lii-CH2 can be powered by any standard USB adapter, power bank, or laptop. Its high-definition LCD display provides real-time data for each slot, including battery type, voltage, charging current, and battery percentage.
