Product Description

XTAR 21700 battery with built-in USB-C charging

The charging port is built into the cell itself, so there's no separate bay charger to buy or carry, plug a USB-C cable straight into the battery. A small LED indicator shows remaining charge, useful for knowing where you stand before heading out rather than guessing.

5000mAh capacity, 10A max continuous discharge, flat top for wide compatibility with popular flashlight brands including Ledlenser, Olight, Fenix and Nitecore. Protected against overcharge, over-discharge and short circuit, rated for roughly 800 recharge cycles.

A convenient pick for EDC carry or backup power where charging simplicity matters more than maximum discharge current. The XTAR 21700 RAW trades the built-in charger for up to 90A of discharge current.

Best Uses

Flashlights from popular brands including Ledlenser, Olight, Fenix and Nitecore, or any other 21700-compatible device.
