High Light 15A High Drain USB C Battery5500mAh Capacity 21700 Battery500+ Recharge Cycles Rechargeable Lithium Battery
High Capacity USB C Batteries with 15A High Drain Power for Enhanced Supply Chain Efficiency and Device Compatibility
Simplify Your Supply Chain with 15A High-Drain USB-C Power

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.

Why Wholesale & Distribute XTAR 21700 USB-C?
  • Eliminate False Low-Voltage Complaints: Stable 15A continuous discharge ensures perfect compatibility with high-drain devices like tactical flashlights, diving lights, and portable fans. Prevents premature shutdowns that cause costly RMA claims.
  • Optimize Logistics & ESG Compliance: With 500+ recharge cycles, one battery replaces hundreds of disposable cells. Slash bulk shipping weight, reduce warehousing space, and help clients meet sustainability targets.
  • 5500mAh True Capacity: High-capacity cell provides longer runtime, reducing the need for frequent recharging and improving end-user satisfaction.
  • All-Round Safety Protection: Smart chip monitors performance in real time with 6-layer protection (over-charge, over-discharge, over-voltage, over-current, short-circuit, temperature).
