Nitecore BATTERY CHARGER 4-SLOT/CI4 NITECORE

he Nitecore Ci4 is an intelligent, four-slot, USB-C battery charger designed for a wide variety of rechargeable batteries, making it a versatile tool for anyone with multiple battery-powered devices.

Here's a detailed description:

Key Features:

• Four Independent Charging Slots: The Ci4 features four independently controlled charging bays, allowing you to charge different battery types and sizes simultaneously without interference.

• Broad Battery Compatibility: It supports a vast range of rechargeable batteries, including:

  • Li-ion (Lithium-ion) and IMR batteries: Such as 10440, 14500, 14650, 16340 (RCR123), 18350, 18500, 18650, 21700, 26650, and many other sizes up to 26700. It can also handle protected 20700/21700 batteries.

    Ni-MH (Nickel-Metal Hydride) and Ni-Cd (Nickel-Cadmium) batteries: Including common sizes like AA, AAA, AAAA, C, and D.

• USB-C Input with Quick Charge (QC/PD) Support: The charger is powered via a modern USB-C port. When connected to a Quick Charge (QC 2.0) or Power Delivery (PD) compatible adapter or power source (which is not included), it can achieve faster charging speeds.

• High Charging Speeds:

  • Fast Charge Mode: Up to 3,000mA (3 Amps) in a single slot when using a QC/PD compatible input.

  • Standard Mode: Up to 2,000mA in a single slot.

  • The charging current dynamically adjusts based on the number of batteries inserted (e.g., 1,500mA x 2 slots, 1,000mA x 3 slots, 750mA x 4 slots in Fast Charge Mode).

• Intelligent Automatic Detection:

  • Battery Type and Capacity: The Ci4 automatically detects the inserted battery's type (Li-ion, Ni-MH/Ni-Cd) and its capacity.

  • Charging Mode and Current: It then automatically selects the appropriate charging voltage and mode (CC - Constant Current, CV - Constant Voltage for Li-ion; -dV/dt for Ni-MH/Ni-Cd) and sets the optimal charging current for each battery.

• LED Indicators: Simple and clear LED indicators show the charging progress and battery power level for each slot. A red indicator lights up for Fast Charge mode.

• Safety Features: Nitecore prioritizes safety, and the Ci4 includes multiple protections:

  • Reverse Polarity Protection: Prevents damage if a battery is inserted incorrectly.

  • Short Circuit Protection: Protects against short circuits.

  • Over-Discharged Battery Activation: Can often revive seemingly "dead" over-discharged Li-ion batteries with protective circuits.

  • Overtime Charging Protection: Automatically stops charging a slot if the uninterrupted charging time exceeds 10 hours to prevent overcharging.

  • Intelligent Temperature Regulation: Monitors the internal temperature to prevent overheating.

  • Durable, Fire-Retardant Materials: Constructed from PC materials designed to be durable and fire-retardant.

• Compact and Portable: With dimensions of approximately 148mm x 105mm x 37mm and a weight of around 191.4g (without cable), it's relatively compact and easy to carry for travel or outdoor use.

In summary, the Nitecore Ci4 is a highly capable and user-friendly battery charger that offers impressive speed, wide compatibility, and a robust suite of safety features, making it an excellent choice for managing a diverse collection of rechargeable batteries.
