Stop losing B2B margins on external chargers and complex bundles. The XTAR 21700 5500mAh USB-C battery integrates a built-in USB-C port and smart charging chip directly into the cell. No dedicated charger is required—end-users simply plug in a standard USB-C cable to recharge from a wall adapter, power bank, car charger, or laptop. This reduces your bill of materials and eliminates mechanical charging contacts for OEM clients.
