The Nitecore Ci2 is a compact, intelligent USB-C dual-slot charger with support for fast charging and broad battery compatibility. It is designed for portability and includes multiple safety features.
Key features
- Dual-slot charging: The Ci2 can charge two batteries simultaneously and control each charging slot independently, allowing for mixed battery types.
- Fast charging: With a QC/PD-compatible adapter, the fast charge mode provides a maximum output of 3,000mA to a single slot. This can charge a 3,500mAh 18650 battery from 30% to 80% in about 35 minutes.
- USB-C power input: The modern USB-C port offers flexibility, allowing you to power the charger from a variety of sources, including wall adapters, power banks, and solar panels.
- Intelligent charging: The charger automatically detects the battery type (Li-ion, Ni-MH, or Ni-Cd) and capacity to select the appropriate charging mode (CC, CV, or -dV/dt).
- Broad battery compatibility: The Ci2 supports a wide range of popular rechargeable batteries, including:
Li-ion/IMR: 10440, 14500, 16340 (RCR123), 18650, 21700, 26650, and many more.
Ni-MH/Ni-Cd: AA, AAA, AAAA, C, and D. - Safety features: Built from durable, fire-retardant materials, the Ci2 includes multiple safeguards:
Overtime charging protection.
Overcharge protection.
Short circuit protection.
Reverse polarity protection.
Optimized charging for IMR batteries. - Over-discharged battery activation: The charger can attempt to reactivate drained Li-ion batteries with a protective circuit.
- User-friendly indicators: Simple, color-coded LED indicators show the charging status and approximate battery level.
