The Nitecore UI2 is an ultra-compact 79.5g dual-slot USB-C charger capable of charging two Li-ion batteries simultaneously with independent control of each slot. Compatible with 21700, 18650, 20700, RCR123 and dozens of other Li-ion/IMR formats, it draws power from a power bank, 5V solar panel or USB adapter for unlimited charging autonomy in the field. An intelligent charger with automatic CC/CV mode selection, the UI2 is the ideal portable charging companion for multi-battery users.

Intelligent Charging and Complete Protection

The UI2 delivers up to 1000mA per slot and automatically adapts the charging current to the type and capacity of each battery. Its reactivation mode handles deeply over-discharged batteries (< 2.9V) at a gentle 100mA, then automatically switches to standard 1000mA mode once voltage recovers. Automatic termination upon full charge protects batteries. Its real-time indicators display the level and charging status of each slot. In case of reverse polarity or short circuit, 3 flashing indicators signal an error immediately. The thermal protection automatically regulates current if temperature becomes excessive.

Portable Construction and Universal Compatibility

The UI2 stands out for its versatility and durability: built from durable fire-retardant PC materials with optimal heat dissipation design, it withstands intensive use. At 79.5g and 125.5mm × 59.5mm × 32.1mm, it fits in the palm of your hand for easy pocket or bag carry. Insured worldwide by Ping An Insurance (Group) Company of China. Compatible with the full range of 3.6V/3.7V Li-ion/IMR batteries, the UI2 is the reference portable universal charger.

Operating Instructions

Standard Charging (> 2.9V): Insert the battery into the slot. Charging starts automatically at 1000mA. Indicators display real-time level.

Reactivation (< 2.9V): Over-discharged battery is detected and gently recharged at 100mA until recovery, then automatically switches to standard mode.

Defective Battery: If indicators light up without progression, stop charging immediately. Never charge an unprotected 0V Li-ion battery.

Dual Charging: Insert one battery per slot. Each slot operates independently.

Reverse Polarity Protection: If battery is inserted backwards, 3 indicators flash. Reinsert the battery correctly.
