Recharge your lithium-ion batteries quickly and efficiently with the F2 Flexible Power Bank from NITECORE. This lightweight, portable, and convenient unit is compatible with various Li-ion/IMR cells, including 18650, 26650, 14500, 10440, 17670, 18490, 17500, 17335, and 16340 (RCR123). With these batteries, you can power cameras, flashlights, headlamps, and many more electronics.
The bank charges 2 batteries simultaneously in compact, independent channels, and, thanks to its Intelligent Power Management System, automatically detects the battery types and selects the appropriate current and mode. Once the batteries are full, an automatic shut-off function prevents overcharging.
Additionally, the F2 has a micro-USB port that lets you draw power from multiple input sources, including solar panels. It's also equipped with a full-size USB port and cable for charging your smartphone or other electronic devices while you charge your batteries. If the input is insufficient to charge all the cells and your device, the power bank will divert 500mAh of current to the batteries and allocate the remainder to your device.
You need not worry about damage to your Li-ion cells, as the F2 offers protection against reverse polarity and short-circuiting. Built for durability, the charger is made of polycarbonate and features gold-plated battery contacts, which are resistant to sweat and the elements while protecting metal components in Li-ion cells from oxidization and corrosion.
