Nitecore Ci4 USB-C charger - 4-slot QC/PD fast charger for Li-Ion & NiMH/NiCd
Item number: 500113
Manufacturer: Nitecore
The Nitecore Ci4 USB-C charger is capable of charging up to four Li-ion or NiMH batteries simultaneously - with up to 3 A charging current on a single slot, depending on the power source and the number of charging slots occupied.
USB-C charger - 4-slot QC/PD fast charger for Li-Ion & NiMH/NiCd batteries
The Nitecore Ci4 is an intelligent USB-C charger with four independently controlled bays. It supports QC / PD and delivers up to 3,000 mA per slot (with a suitable QC/PD power adapter). The Ci4 automatically recognises the battery type and capacity, selects the appropriate charging algorithm(CC, CV, -ΔV/dt) and reliably protects against overcharging, short circuits, reverse polarity and overheating. Ideal for Li-Ion/IMR (3.6/3.7 V) and NiMH/NiCd (1.2 V) - from 10440 to 26650/21700.

Important notes
- Not compatible with LiFePO₄ (3.2 V) and 3.8 V Li-Ion (4.35 V charge limit) - these chemistries are not supported by the Ci4.
- A QC/PD power adapter is required for fast charging (use USB-C to USB-C cable)
- Recommended max charging current for Li-Ion: ≤ 1C (means 1 x the capacity).
- Do not charge primary cells (e.g. CR123A).
