Winna heated gloves are equipped with a built-in intelligent temperature control chip and temperature sensor, which can detect the temperature inside the gloves in real-time and intelligently control the current and voltage output to achieve a constant temperature state inside the gloves. When the temperature sensor detects that the temperature inside the gloves exceeds 70°C (158°F), the heating will automatically stop to ensure safety. In addition, it also has a temperature memory function that automatically adjusts to the temperature set before the last shutdown every time the system is restarted, making your use more convenient!
