To recharge, connect a USB-C cable from a compliant USB power source to the cell’s USB-C port; charging behavior follows the cell’s internal charging circuitry. Avoid inserting the cell into devices that require protected or specially matched battery packs unless the device supports single 18500 cells with built-in charging.
