The Nitecore Carbon Battery 6K provides extra power for your devices when you're on the go, from headlamps to smartphones, races to emergency situations. Featuring a lightweight carbon fibre shell, the portable battery has a USB-C input and output for recharging and discharging (cable not included). The Carbon Battery 6K takes priority when powering a device such as a Nitecore headlamp; the external battery will be used first to preserve the device's own battery.

The Nitecore battery has 3 red power indicators to advise on the battery level:

• 3 lights = 100%
• 2 lights = 70%
• 1 light = 30%
• 1 flashing light = <10%

The indicators also serve as a red safety light for extra visibility at night or emergency signalling.

The Nitecore Carbon Battery 6K has a waterproof rating of IP68 and an impact resistance of up to 1 meter.
