NITECORE NEW I4 Smart Battery Charger Case for Li-ion / IMR / LiFePO4 - Black US Plug (2-pin)

Main Features:
Up to 100% increase in charging speed
NEW i4 provides single-slot charging up to 1500mA current output, charging efficiency is 100% higher than i4, so your charging time is reduced by half

Active current distribution technology
ACD technology allows the full power of the charger to be automatically distributed among the four slots. For example, when one of the batteries in the four slots is fully charged, the charger with the ACD function will deliver all the power to the other slot to charge the undercharged batteries

Added support for 3.7V and 4.35V batteries
NEW i4 provides 1.2V, 3.7V, 4.2V and 4.35V charging voltage specifications, which is compatible with almost all cylindrical rechargeable batteries on the market. By pressing the "V" key, the required charging voltage can be independently selected for each slot. At the same time, the use of 3.7V charging voltage is helpful for long-term storage and transportation of batteries

IMR battery repair function
Simultaneously press and hold the "C" and "V" buttons to activate the IMR battery repair function to repair the IMR battery that has been over-discharged to 0V

Automatically select the appropriate charging current according to the battery capacity
After inserting the battery, the NEW i4 will automatically select the appropriate charging current for charging according to the battery capacity and type
When using large capacity batteries such as 18650 or 26650, you can start the 1500mA fast charging function by long pressing the "C" key
When using small capacity batteries such as 10440 and 16340, the charger will automatically select 500mA low current charging

Fully automatic and fully compatible
The built-in microcomputer automatically detects the battery type and automatically selects the appropriate charging procedure, voltage and current for charging. Automatically detect the battery power status, and automatically select the appropriate charging mode (constant current, constant voltage and trickle charge)

Add -dV/dt charging function
The -dV/dt charging function is added to nickel-metal hydride and nickel-cadmium rechargeable batteries, which can accurately detect the battery status and determine the timing to stop charging, so that nickel-metal hydride and nickel-cadmium batteries can obtain the largest possible charging capacity without overcharging

Use specially optimized charging program
Because the internal resistance of IMR batteries is much lower than that of ordinary lithium-ion rechargeable batteries, using a general lithium battery charger to charge them may cause over-discharge problems and even lead to safety risks.
NEW i4 introduces optimized charging procedures, comprehensively optimizes the design of IMR battery charge status and strictly monitors the whole process to ensure that the charging cut-off voltage of IMR batteries is within a safe range, greatly improving safety and effectively extending battery life.

Anti-reverse protection, safe and secure
When the battery is reversed, the charger will light up 4 LEDs to warn and automatically stop charging

Strict charging timeout protection procedure
The NEW i4 charger will independently calculate the battery charging time of each slot. When the charging time exceeds 20 hours, the charger will forcibly turn off the charging function of the slot and display the full charge sign to effectively prevent battery overcharge or safety accidents

High-quality materials, safe and reliable
Using PC fire-retardant and flame-retardant materials, high-quality materials to create a hard shell, extend the service life and enhanced safety performance, just to give you lasting and safe companionship

Automatic intelligent temperature control protection program
Built-in real-time temperature control protection system to prevent high temperature and ensure the stability of the charging process

Fine design, tightly integrated
Adopt all-copper metal positive contact design, greatly reduce the contact resistance of the charger electrode, make the battery charging voltage accurate, less heat, and ensure smooth sliding when installing the battery

Quality is essential, travel necessary
Two kinds of power input are applicable, compatible with car and indoor charging, travel and at home, everything is ready
