Nitecore I2 Intellicharger

The New i2 charger from Nightcore enhances the original model with six major upgrades:

• 100% faster charging
• active current distribution (ACD) technology
• Broader voltage compatibility: 3.7 and 4.35V batteries 
• IMR battery restoration 
• Automatic current selection based on capacity
• Automatic Detection of Non-rechargeable Lithium batteries.

With 100% charging acceleration, the New i2 delivers up to 1000mA to a single slot.

Thanks to Active Current Distribution, the charger dynamically allocates power. When two batteries are charging and one finishes, the New i2 automatically channels all power to the remaining slot for the fastest possible charge.

Its expanded voltage support - 1.2V, 3.7V, 4.2V and 4.35V lets you charge a wide variety of cells using one device. Voltage for each slot can be set independently via the V button. 

The New i2 also features IMR battery restoration, capable of reviving 0V-depleted cells by pressing and holding the C and V buttons simultaneously.

Additionally, it automatically selects the optimal charging current by detecting battery capacity.

Compatible batteries include:

Li-ion / IMR / LiFePO4:
