01. Excellent charger with four charging positions.
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

02. QC / PD input available
The Ci4 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.

03. 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%

04. Smart and user friendly
– ​​Automatic selection of charging current.
– Automatic control of the battery energy level.
– Automatic termination of charging upon its completion.

05. 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

07. Specially designed charging program for IMR batteries
The Ci4 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.

08. Indicator lights in a straight column for each charging position.
– Red indicator light permanently on to indicate fast charging.
– Three green indicator lights permanently lit to indicate 100% full charge
– Two green indicator lights permanently lit to indicate approximately 80% full charge.
– A green indicator light permanently on to indicate the full charge by approximately 30%.

09. Activation of over-discharged Li-ion batteries
Ci4 is able to activate over-discharged Li-ion batteries with a protection circuit. After inserting the battery, the Ci4 will check and activate the battery before starting the charge. 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 Ci4 will automatically terminate the charging process at that position.

10. Smart charging mode selection
Ci4 will automatically select between 3 charging modes (CC, CV and -dV/dt) according to the battery type and capacity.

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

12.Multiple internal protections
– Long-time charging protection
– Short circuit and reverse polarity protection circuit.
– Intelligent temperature regulation

13. Power saving function
All indicator lights will automatically turn off when no battery is installed in the slots.

14. 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.
