140W Smart Auto-Stop USB-C Charging Adapter | Overcharge Protection

Never Overcharge Your Devices Again

Meet the 140W Smart Auto-Stop USB-C Charging Adapter — the intelligent charging protector that automatically disconnects when your device reaches 100%, keeping your battery healthy and your mind at ease. Whether you're charging overnight or just stepping away from your desk, this compact gadget has you covered.

Key Features

• 140W Ultra-Fast Charging Support: The adapter itself supports up to 140W output, while the connected USB-C cable handles up to 100W — dramatically cutting down charging time for laptops, smartphones, tablets, and other Type-C devices.
• AI Intelligent Auto-Disconnect Technology: An advanced AI smart chip monitors your device's battery level and physically disconnects the internal connection the moment your device hits full charge. No more wasted energy, no more battery degradation from prolonged charging.
• Colorful Atmosphere LED Ring: A built-in colorful LED light ring (or "100%" LED display) gives you a clear, at-a-glance view of your charging status. Functional and stylish — a patented design that sets this adapter apart.

Frequently Asked Questions

Q: How does the 140W Smart Auto-Stop Charging Adapter protect my device's battery?

A: The adapter uses an AI smart chip to monitor your device's charge level in real time. Once the battery reaches 100%, the internal connection is physically disconnected, automatically stopping the flow of electricity. This prevents overcharging and helps maintain long-term battery health — especially useful during overnight charging.

Q: Is this USB-C charging adapter compatible with my laptop or smartphone?

A: Yes! This adapter is universally compatible with any USB Type-C device, including laptops, tablets, smartphones, power banks, small fans, shavers, beauty instruments, and electronic toys. As long as your device uses a USB-C port, this adapter will work with it.

Q: Does the 140W charging adapter come with a USB-C cable?

A: No, a charging cable is not included in the package. You will need to supply your own USB-C cable. For full-speed charging (up to 100W via cable), make sure your cable supports high-wattage power delivery.

Q: What does the LED light ring on the charging adapter indicate?

A: The built-in colorful atmosphere LED ring provides a real-time visual indicator of your charging status. When your device is fully charged and the adapter auto-disconnects, the display shows "100%" or the light ring changes to signal that charging is complete.
