Description
Nitecore Ci4 • 4-Bay USB-C Intelligent Battery Charger
The Nitecore Ci4 is a versatile 4-slot USB-C charger for Li-ion/IMR/INR, LiFePO4 and Ni-MH/Ni-Cd cells.
With automatic chemistry detection, independent channel control and adaptive charging algorithms, it delivers fast, reliable charging while protecting your batteries from over-charge, reverse polarity and short-circuit conditions.
Smart, safe, and efficient
The Ci4 automatically identifies battery chemistry and state of charge, selecting a suitable current for each bay.
Every slot is independently controlled, so you can charge different chemistries and sizes at the same time.
Safety features include reverse-polarity protection, short-circuit protection,
over-charge protection, and thermal management.
Status LEDs provide clear feedback for power, charging and full. The USB-C input supports standard 5V and QC/PD fast-charge sources.
For the highest rates (e.g., 2A single-slot or multiple bays at 1A), use a QC/PD wall adapter rated around 18–30W.
Power adapter not included.
Cell compatibility
- Li-ion / IMR / INR (3.6/3.7V): 10440, 14500, 14650, 16340 (RCR123A), 17350, 17500, 18350, 18490, 18500, 18650, 20700, 21700 (unprotected & most protected), 22650, 25500, 26500, 26650
- LiFePO4 (3.2V): supported (manual selection recommended)
- Ni-MH / Ni-Cd (1.2V): AAA, AA, A, SC (as size permits)

David Jones –
It is a great charger, you only get max charging speed using one slot. Not really a problem as I leave them overnight.
