PRODUCT DESCRIPTION
Nitecore Ci4 Four-Slot USB-C Battery Charger for Li-ion, Ni-MH Cells
The Nitecore Ci4 is a four-slot battery charger designed for simultaneously charging a range of rechargeable cells. It is compatible with both Li-ion (Lithium-ion) batteries, including popular sizes such as 18650 and 21700, and Ni-MH/Ni-Cd batteries (Nickel-metal Hydride/Nickel-cadmium). This broad compatibility allows it to charge various battery types commonly used in vaping devices and other portable electronics.
The charger incorporates an optimized IMR battery charging program. This program continuously monitors the entire charging cycle to help ensure that the cut-off voltage always remains within safe limits. This precise management aims to contribute to the extended lifespan of the compatible batteries.
Equipped with a USB-C charging port, the Ci4 can support a maximum input charging current of 3000mA when charging a single battery. The current output scales down when more slots are in use (e.g., 1500mA for two slots, 750mA for four slots in Fast Charge Mode). This higher current capability can reduce the time required to fully charge compatible batteries. The USB-C port is reversible, simplifying connection, and automatically detects Quick Charge (QC) or Power Delivery (PD) input. This allows the charger to draw power from various sources, enhancing flexibility for users in different environments.
The Nitecore Ci4 features a dual external protection system. This system is designed to provide both efficient heat dissipation and enhanced durability, making the charger suitable for use in varied conditions. The charger is constructed from durable, fire-retardant PC materials for enhanced safety during operation.
Multiple safety features are integrated into the Ci4. These include reverse polarity protection, which helps prevent damage if a battery is inserted incorrectly, and short circuit prevention. The charger automatically selects between three charging modes—Constant Current (CC), Constant Voltage (CV), and –dV/dt—based on the battery type and status. It also automatically detects the battery's power level and terminates charging upon completion to prevent overcharging. An over-discharged Li-ion battery activation function can attempt to revive certain deeply discharged Li-ion cells. The device also includes an energy-saving function and straightforward power indication for user convenience.
