The Nitecore F4 is a charger and power bank that can accommodate four batteries simultaneously. Building upon the success of the F1 and F2 chargers, this device allows you to charge up to four cells or use the batteries to power other electronic devices. The F4 has a unique sliding cover that keeps the batteries safe and protected, while providing excellent dust and weather resistance.
When used as a battery charger, the Nitecore F4 can charge each battery with a maximum current of 1A in a single slot. As a power bank, the F4 has a single USB port that can output up to 2A to power devices such as tablets, smartphones, and cameras.
The F4 also features a real-time LCD display that provides information on battery status, including voltage, charging current, charged volume, USB output current, and output volume. To save energy, the F4 automatically enters Energy Saving Hibernation Function to shut the screen down when there is no operation and no input or output in 10 minutes, or long press the power button for 10 seconds when there is no input or output.
The charger also includes an intelligent charging mode that automatically detects the battery level and adopts the optimal charging mode (CC or CV). The F4 is designed to activate over-discharged Li-ion batteries and protect against short circuiting and reverse polarity.
The F4 is compatible with Li-ion and IMR 18650 cells.
