Nitecore® Carbon Battery™ 12K Extended Headlamp Runtime Kit

Carbon Battery™ 12K extended headlamp runtime kit is a high capacity external battery kit for compatible Nitecore® headlamps, built for longer sessions and higher output demand. It delivers 12,000mAh (43.2Wh) via USB-C and can also provide backup power for other USB-C devices. A rugged carbon fiber shell and IP68 rating make it suitable for wet, muddy or dusty conditions.

The battery mounts to the headband for a stable, well-balanced fit, and a quick-release clip helps keep the connection secure. A rear red safety light improves visibility from behind, while the LED power bar shows remaining charge at a glance. When connected to compatible headlamps, the system prioritises drawing power from the external battery.
