Full Product Description

Protect Your Battery with Intelligent Auto-Disconnect

Overcharging degrades lithium-ion batteries, leading to shorter lifespans and potential swelling. The KUWAJIA KH-51 Adapter actively monitors your battery's status. Once your device hits 100%, the adapter initiates a 10-to-50-minute trickle charge before completely cutting off the power. Enjoy total peace of mind during overnight charging.

True 140W Fast Charging for All Devices

Don't compromise on speed for safety. This adapter supports up to 140W power delivery, making it fully compatible with high-draw devices like modern laptops, tablets, and flagship smartphones. It seamlessly passes through maximum power without bottlenecking your original charger.

Innovative Physical Disconnect & Testing Mode

Unlike software-based limiters, the KH-51 features a physical disconnect mechanism. When triggered, soft silicone pads gently push the adapter away from your device, ensuring zero damage to your Type-C port. Want to verify it works? Use the built-in Function Test: simply hold the button for 5 seconds to see the white and blue lights flash, followed by an automatic power cut.
