Automatic Smart Charging

The Nitecore F2 Flexible Power Bank can charge 2 batteries simultaneously. Its built-in microprocessor allows it to identify the battery type and select the appropriate current and voltage. LED indicators display charge status so you quickly see if your batteries are charged, or how much power is left if using the batteries to charge other devices.

Wide Compatibility

Designed for high-drain power sources, the F2 Flexible charger is compatible with a range of lithium-ion or IMR batteries. It also features a USB 3.0 Micro-B port (with Micro USB support) which offers more efficient battery charging and the ability to connect it to other power sources.

Adaptive Current Distribution

The F2 charger can automatically choose the most appropriate charging current based on the battery placed in each charging slot. It also detects battery status, whether it’s depleted or half charged, and intelligently selects a suitable current to safely continue charging.
