Description

Turn your Lithium Ion batteries into a power source for your devices with the Nitecore F2 Flexible Power Bank! This compact adapter takes your rechargeable batteries, typically used in flashlights and other high powered electronics, and transforms into a portable power bank for your cell phone, camera, or other USB-rechargeable electronics. Less than 4 inches long, this handy tool is compatible with a wide range of cylindrical Li-Ion battery sizes, including 18650, 16340 (RCR123A), and 14500, allowing you to use whichever batteries you have available. The F2 even comes with a pair of rubber bands to hold the cells in place while in use. The power bank comes equipped with two USB outputs, each capable of outputting 2.0 Amps of current to quickly recharge your device. The charger comes with a 3-LED power indicator for each bay so you can keep track of the remaining charge of your newly-fashioned power bank.
