The NEW i2 charger from Nitecore improves upon the original model with six new features:100% Charging AccelerationActive Current Distribution TechnologyExpanded Compatibility to Support 3.7V and 4.35V batteriesIMR Battery RestorationAutomatic Current Selection Based on Battery CapacityAutomatic Detection of Non-Rechargeable Lithium Batteries100% Charging acceleration means the NEW i2 can charge at up to 1000mA current in one slot.Active current distribution (ACD) technology allows for the dynamic distribution of the NEW i2's charging power. For example, when two batteries are being charged in the NEW i2 and one of them completes charging, all charging power will automatically go to the other slot and charge the battery at the fastest speed.Expanded compatibility to support 3.7V and 4.35V batteries allows you to charge a host of batteries with a single charger. Compatible with 1.2V, 3.7V, 4.2V and 4.35V. By simple operation with the V button it is easy to set charging voltage in each slot independently.IMR battery restoration will attempt to restore deeply discharged cells by pressing and holding both the C and V buttons simultaneously.The NEW i2 can intelligently select the most appropriate charging current based on automatic battery capacity detectionSafety features include:Optimisation for IMR charging by monitoring the voltage stays within safe limitsOvertime charging protection, limiting to 20 hoursMade from fire retardant, flame resistant materialsAutomatic Intelligent Temperature Control preventing overheatingCompatible with Li-ion/IMR/LiFePO4: 10340, 10350, 10440, 10500, 12340, 12500, 12650, 13450, 13500, 13650, 14350, 14430, 14500, 14650, 16500, 16345 (RCR123), 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500, 18650, 18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650 and Ni-MH (NiCd): AA, AAA, AAAA, C, D.Input: AC 100~240V 50/60Hz 0.25A (max) 8W
