Type-C Auto Cut-Off Charging Adapter | Full Charge Disconnect

Smart Type-C Charging Adapter with Auto Cut-Off Technology

Stop worrying about overcharging your devices. This Universal Auto Disconnect Charger Adapter intelligently monitors current and voltage during charging — automatically cutting power once your device reaches full charge. Whether you're charging a smartphone, power bank, Bluetooth headset, or electric shaver, this compact adapter keeps your battery in optimal condition and helps conserve energy.

Two Smart Charging Modes

Switch between modes with a single press of the button:

• White Light Mode (Type-C): Designed for screen-enabled devices like smartphones and tablets that remain powered on during charging. The adapter automatically cuts off power approximately 10–50 minutes after the device displays 100% battery, allowing trickle charging to complete first.
• Blue Light Mode (Type-C): Ideal for screenless devices such as Bluetooth headsets, power banks, electric shavers, beauty instruments, and children's toys. Power is automatically disconnected roughly 5 minutes after full charge is detected.
• Lightning Mode: Single-mode operation for Lightning-compatible devices — simple and automatic.

How the Auto Disconnect Works

This adapter assesses battery status by monitoring the real-time current and voltage of the connected device — not by interfacing with the device's battery management system. Because of this, devices with active displays (phones, tablets, laptops) may show 100% battery while still undergoing a brief trickle-charge phase. The adapter accounts for this by waiting the appropriate extra time before disconnecting. Different devices and battery health levels may affect trickle charge duration.

Function Test Mode

Want to verify the auto-disconnect feature is working? During active charging, press and hold the button for 5 seconds until the white and blue lights flash alternately. Release the button — the adapter will automatically cut off power after 5 seconds, confirming the disconnect function is operating correctly.

Compact & Travel-Friendly

Weighing just 25.5g and built from durable fire-resistant polycarbonate, this splitter adapter is lightweight enough to toss in your bag and rugged enough for daily use. Made in Mainland China.
