Why Choose a Smart Stop-Charge Adapter?

Traditional chargers continue to push power into your battery even after it's full, generating heat and gradually reducing battery capacity over time. This smart charger physically disconnects the circuit the moment charging is complete — acting like someone unplugging the charger for you. The result? A longer-lasting battery and a safer overnight charging experience.

Frequently Asked Questions

Q: How does the automatic physical-disconnect feature work on this USB-C smart charger?

A: When your device's battery reaches 100%, the charger's built-in smart circuit physically interrupts the power connection — completely stopping the flow of electricity. Unlike software-based solutions, this is a hardware-level disconnect, meaning no current flows to your device after charging is complete. This protects your battery from the wear caused by prolonged overcharging.

Q: Is a USB-C charging cable included with this 140W charger adapter?

A: No, a USB-C cable is not included. You will need to use your own compatible USB-C cable to connect the adapter to your device. Make sure your cable is rated to handle the wattage you intend to use for optimal charging performance.

Q: What devices are compatible with this Type-C smart stop-charge adapter?

A: This adapter is compatible with any device that charges via USB-C, including modern smartphones, tablets, laptops, earbuds cases, and more. It supports Qualcomm Quick Charge protocols, making it especially effective with devices that are Quick Charge enabled. Always verify your device's maximum supported wattage before use.

Q: Does this charger work with Qualcomm Quick Charge devices?

A: Yes! This smart charger supports Qualcomm Quick Charge protocols, allowing compatible devices to charge significantly faster than with a standard adapter — while the auto-disconnect feature ensures the process stops safely once full charge is reached.
