How It Works

The adapter detects when charging is effectively complete by monitoring charging current and voltage. It does not communicate with your device's internal battery management system.

• Phones, Tablets & Laptops: After your device displays 100%, the adapter usually disconnects 10–50 minutes later, allowing the battery to finish its final charging phase.

• Earbuds, Power Banks & Other Small Devices: Automatically disconnects about 5 minutes after charging is complete.

Package Includes

• 1 × 140W Smart Auto Disconnect Type-C Adapter

Important Notes

• Devices already charged above 99% may not trigger the automatic disconnect correctly.
• For recessed or uneven USB-C ports, connect the adapter to the charger instead of directly to the device.
• Use only with horizontal or desk-level power outlets to prevent damage if the adapter ejects.
• Do not use on vertical wall outlets.
• Keep away from water and moisture.
