Nitecore Ci4 Universal Intelligent Charger - Four Charging Slots

The Nitecore Ci4 Intelligent Charger is a portable 4-slot charger for Li-ion batteries and Ni-MH/Ni-Cd cells with maximum output of 3000mA. Equipped with a USB-C port with QC/PD support, it enables fast charging and can be powered by external battery or solar panel. Revolutionary technology to charge IMR batteries and restore over-discharged Li-ion batteries. The 4 slots are independently controlled with automatic detection of battery type and intelligent charging current selection.

USB-C Port and QC/PD Fast Charging Mode

The Ci4 integrates a USB-C port allowing connection via external battery or solar panel for portable charging. Fast charging mode automatically activates with QC/PD source: 1500mA per slot with 2 batteries or 750mA per slot with 4 batteries. Standard mode: 1000mA per slot (2 batteries) or 500mA per slot (4 batteries). LED indicators show charging status (flashing green LEDs) and fast mode activation (red indicator). Energy saving function: screen automatically turns off after a few minutes of inactivity.

Intelligent Charging and Maximum Safety

The Ci4 automatically detects battery type (Li-ion or Ni-MH/Ni-Cd), capacity and selects appropriate charging mode (CC, CV or -dV/dt). Capable of restoring over-discharged Li-ion batteries with protection circuit. Complete protection: anti-reverse polarity, anti-short circuit, overcharge protection (automatic stop after 10h). Automatic stop at end of charge. Made from durable fire-resistant PC materials with optimal heat dissipation. RoHS, CE, FCC and CEC certifications.
