An 18650 that charges itself, straight from any USB-C cable.

A 4,000mAh protected 18650 with a built-in USB-C port, so a power bank or a phone charger tops it up with no separate charger needed.

  • 4,000mAh, 3.6V, 14.4Wh of energy, roughly four times a CR123A
  • Built-in USB-C port charges directly from a cable or a power bank
  • Red light while charging, green when it is full
  • 6A maximum continuous discharge for high-drain lights
  • Intelligent protected circuit plus a pressure-relief valve for safety
  • Rated for over 500 charge cycles, keeping more than 90% capacity
  • The exact cell that powers the Nitecore UT6 headlamp

Charge it with the cable already in your bag.

The USB-C port is built into the cell itself, so a wall charger, a laptop or a power bank brings it back to full. Pack one cable for your phone and the same one tops up this battery.

A small light on the cell tells you where you stand. Red stays on while it charges, and it turns green the moment it is full, so you can leave it and check at a glance.
