Say goodbye to overnight overcharging! The Full-Charge Cutter is equipped with an AI chip that automatically disconnects the power supply the moment the battery is fully charged. It supports 140W super-fast charging and is compatible with Apple, Android, tablets, and laptops. It makes nighttime charging safer and helps protect your battery’s health and lifespan.
Do you face these issues too?
You plug in your phone before bed, only to wake up the next morning to a phone as hot as a hand warmer.
Your battery health drops rapidly, and replacing a battery costs hundreds of yuan.
You worry about fire hazards from overnight charging and wake up in the middle of the night to unplug it.
You always forget to unplug small appliances, power banks, and electric razors after they’re fully charged.
Modern devices’ built-in power management ≠ physical power disconnection.
Although electronic devices like smartphones and tablets are generally equipped with comprehensive power management systems to prevent overcharging, hidden drain factors—such as “phantom power consumption,” “temperature rise,” and “stealth charging in the background”—still exist. What truly damages the battery is remaining at 100% charge for extended periods.
The Full-Charge Disconnector: One plug-and-unplug action, a lifetime of protection.
Core Technology Breakdown
🧠 AI Smart Chip · Precise Recognition of Charging Status
The built-in AI smart detection chip monitors voltage and current changes in real time throughout the entire charging process. Rather than simply disconnecting as soon as it detects 100%, it precisely identifies when the device has completed trickle charging and the battery is truly saturated before triggering the power cut-off.
Dual Current Recognition Modes, Compatible with Various Devices:
Mode: Light Compatible Devices
White Light Mode: White Indicator Light Smartphones, tablets, laptops, and other screen-equipped devices in standby mode
Blue Light Mode: Blue Indicator Light Power banks, small fans, electric shavers, beauty devices, children’s toys, and other electronic products
⚙️ Physical Auto-Ejection · True 100% Power Disconnection
Unlike ordinary chargers, the Full-Charge Disconnector uses a dual-piston physical ejection system. When the device is detected as fully charged, an internal micro-motor drives the pistons to extend, physically ejecting the disconnector from the device’s USB-C port—with a soft “click”—completely severing the power connection.
This is not a software-based “output stop,” but a physical circuit disconnection that eliminates residual charge, overheating, and safety hazards.
🔋 Supercapacitor Power Supply · Instant Ejection Upon Power Disconnection
It features a built-in Jianghai brand supercapacitor (2.7V 0.5F), which provides the ejection power to the micro-motor the moment the external power source is cut off. Even if the charger is suddenly unplugged, the disconnector still has sufficient power to complete the ejection action.

FAQ (Frequently Asked Questions)
Q: Doesn’t my phone already have built-in charging protection? Why do I need this?
A: The “smart charging” feature in your phone’s operating system only controls the charging rate at the software level; it doesn’t actually disconnect the power source. The Full-Charge Disconnector physically disconnects the circuit, completely eliminating the risk of overcharging.
Q: Will it affect fast-charging speeds?
A: No. The disconnector supports a wide input voltage range of 5V–28V and a current output of 0–5A, making it compatible with mainstream fast-charging protocols on the market. Charging efficiency is virtually identical to plugging directly into the outlet.
Q: Does it work with all Type-C devices?
A: Yes. It supports all devices with a Type-C port, including smartphones, tablets, laptops, Bluetooth earbuds, power banks, small fans, electric shavers, beauty devices, and children’s toys.
Q: Does it really “pop out” once fully charged? Will it fly off?
A: The separator gently pushes the device out using two hidden push rods. The motion is gentle and precise, so the device won’t fly off.
Q: Is it safe to charge overnight?
A: It’s very safe. Once fully charged, the circuit is physically disconnected, resulting in zero power consumption and zero heat generation, completely eliminating the risk of fire from overnight charging.
