Nitecore 18650 Extension Battery Case

The Nitecore Extension Battery Case is compatible with a variety of head torches to provide a longer runtime.

Ideal for outdoor excursions such as trail running, climbing and hiking, the unit accommodates one 18650 lithium ion battery which is not included.

It can be used with the following Nitecore head torches:

NU40, NU43 and NU50.

The 18650 case connects directly to the head torch via its USB-C port and attaches to the headband with a sturdy plastic mount. When the light is on, power is taken from the extension case first. The battery case powers the head torch and charges the head torch's built-in battery simultaneously, allowing it to function to its fullest potential.

With both USB-C input and USB-C output the extension case can be used as a battery charger or a power bank, making it ideal for charging various electronic devices.

Blue power indicators can be activated to show the remaining battery level:

4 lights: ≤100%
3 lights: ≤75%
2 lights: ≤50%
1 light: ≤25%

In addition, four flashing red lights are available for safety and emergency use.
