Key Features

Physical “Auto-Eject” Separation: The moment your device is fully charged, an internal electromagnetic release activates, and dual built-in rods push the adapter open. This completely breaks the electrical connection, giving you visible proof of safety.
Massive 140W Fast Charging Support: Fully compatible with ultra-fast charging protocols. It safely passes up to 140W of power (5V-28V at 5A max), meaning you do not have to sacrifice charging speeds to protect your battery.
Dual-Core Smart Protection System: Features two independent intelligent chips that monitor voltage and current trends in real-time. It accurately determines when your battery is completely full—including trickling cycles—before triggering the ejection.
Premium 5A Real Copper Core: Constructed with a high-conductivity, thick copper core that minimizes resistance, reduces heat buildup, and ensures stable power delivery.
Universal Type-C Interface: Designed for the modern tech landscape. Simply plug your standard Type-C cable into the KH-51, and plug the KH-51 into your device.
Dual Rod Balanced Push Force: The ejection system uses dual rods that apply equal force to both sides of the Type-C port, protecting the delicate internal pins of your smartphone or laptop from uneven wear.
Fireproof PC Shell: Built with high-grade, flame-retardant polycarbonate materials to withstand high temperatures during rapid charging sessions.
Feather-Light & Pocket-Sized: Weighing a mere 23.5 grams and measuring just 42mm, this tiny gadget is highly portable and easily fits into any travel bag or pocket.

Dual Smart Charging Modes

The KH-51 features two intelligent charging modes to match different device architectures. You can easily cycle between these modes with a single click of the physical button:

White Light Mode (Screen Devices): Optimized for devices with active background standby processes like smartphones, tablets, and laptops. It keeps the current flowing for an extra 10 to 50 minutes after your screen shows 100% to ensure the battery finishes its crucial trickle-charging phase before ejecting.
Blue Light Mode (Screenless Accessories): Tailored for standard gadgets like TWS earbuds, power banks, electric shavers, and smartwatches. This mode physically disconnects and ejects the current roughly 5 minutes after a full charge is detected.
5-Second Quick Test Function: Want to verify the mechanism? Simply hold the physical button for 5 seconds during active charging. The LED lights will flash alternately, and the adapter will automatically eject itself after 5 seconds to demonstrate its functionality.
