Product Description
Stop battery damage from overnight charging with this USB-C 140W Smart Auto-Disconnect Charger Guard—a patented AI-powered inline device that physically cuts the charging circuit once your device is fully charged. Unlike software-only battery limits, this protector creates a true physical disconnection with zero standby current, eliminating trickle charging and heat buildup that silently degrade your battery over time. Simply plug it between your USB-C cable and device, and charge with complete peace of mind. 🔋🛡️✨
