KUWAJIA KH-51 USB-C Auto Disconnect Adapter
for Power with Automatic Disconnection
and Battery Protection - Silver
The KUWAJIA KH-51 is an innovative USB-C adapter, specially designed to protect your devices' battery health by automatically cutting off power
when charging is complete. Unlike other accessories, this smart relay evaluates the actual battery status
by directly analyzing the current and voltage trends, without attempting to trick the phone's internal management system.
For devices with screens (phones, tablets, laptops), displaying 100% does not mean the battery is fully charged,
as a slow charging period (trickle charging) of another 10-50 minutes is required. The adapter recognizes this algorithm
and only permanently stops power after the battery is charged to its true maximum capacity,
thus preventing overheating, premature cell wear, and battery degradation.
Two Intelligent Operating Modes and Quick Test Function
The device is equipped with two distinct operating modes, easily switched by a simple button press,
each indicated by a dedicated light indicator for maximum efficiency:
White Light Mode: Optimized for screen devices that remain active in the background (phones, tablets, laptops),
cutting off current 10-50 minutes after the 100% charge is displayed.
Blue Light Mode: Specifically configured for accessories without screens and without continuous standby function
(external batteries, Bluetooth headsets, electric shavers, toys), disconnecting power about 5 minutes after full charge.
The compact and lightweight fire-resistant PC construction also features an intelligent test function: by pressing the button for 5 seconds
until the lights flash alternately, the adapter will cut off power after another 5 seconds, allowing you to instantly check the system's operation and safety status.
