Nitecore Intelligent USB-C Dual-Slot Charger Ci2 (Ci2)

Excellent charger with two charging points.

• Smart with USB-C port.
• Compatible with Li-ion and Ni-MH / Ni-Cd batteries.
• QC/PD input available.
• Automatic selection of charging current.
• ​​Maximum charging current 3000mA when charging one battery.
• USB-C charging port.

QC / PD input available.

The Ci2 has the ability to fast charge when powered by a device that supports this QC/PD function or when powered by a power adapter that has this capability.

Maximum charging current 3000mA when charging a single battery.

It only takes 35 minutes to charge a battery from 30% of its energy to 80%.

Smart and user friendly.

• ​​Automatic selection of charging current.
• Automatic control of the battery energy level.
• Automatic termination of charging upon its completion.

USB-C charging port.

The USB-C charging port requires no cable installation and automatically detects the QC/PD supply.
This allows the easy intake of power from many different sources such as

• Adapter with multiple USB outputs, NITECORE UA66Q.
• Ultra-light Power Bank, NITECORE NB1000.
• Portable Solar Panel, NITECORE FSP100.

Specially designed charging program for IMR batteries.

The Ci2 incorporates a specially designed program for charging IMR batteries, which is able to monitor the entire charging process, ensuring that the cut-off voltage is always within the safety limits so as to increase the battery life.

Indicator lights in a straight column for each charging position.

•Red indicator light permanently on to indicate fast charging.
•••Three green indicator lights steady on to indicate 100% full charge.
••Two green indicator lights steady on to indicate approximately 80% full charge.
•A green indicator light permanently on to indicate the full charge by approximately 30%.

Activation of over-discharged Li-ion batteries.

Ci2 is able to activate over-discharged Li-ion batteries with a protection circuit. After inserting the battery, Ci2 will check and activate the battery before starting charging. When the battery is judged to be damaged all the indicator lights above the charging position (One red and Three green) will flash simultaneously to inform the user while the Ci2 will automatically terminate the charging process at that position.

Smart charging mode selection

Ci2 will automatically select between 3 charging modes (CC, CV and -dV/dt) according to the battery type and capacity.

Two external protections

• Unique cooling fins.
  Designed to provide excellent cooling performance by dissipating heat quickly to prevent potential damage.
• Durable and Fire Retardant polycarbonate materials.
  Not afraid of the complex external environment.

Multiple internal protections.

• Long-time charging protection.
• Short circuit and reverse polarity protection circuit.
• Intelligent temperature regulation.

Power saving function.

All indicator lights will automatically turn off when there is no battery installed in the slots.

Authentication to guarantee authenticity and safety.

In the packaging of all genuine NITECORE chargers, there is a 16-digit authentication code and a QR authentication code.
You can also get your charger from the official dealer network.
