Heated Socks I purchased these new, but I haven't had a chance to use them, so I'm putting them up for sale. The product specifications are based on the information provided by the previous seller. Color: Gray系 (Gray-based) Material: Cotton 83% Polyester 10% Urethane 7% Function: Cold Protection Season: Autumn, Winter ○ Performance ○ Rechargeable 3.4V 2200mAh lithium battery Approximately 6-8 hours on low setting 5 hours on medium setting Approximately 4 hours on high setting ○ How to Use ○ 1. Wear the socks, open the package, take out the socks, and put the socks on your feet. 2. Connect the battery power, remove the link wire inside the socks, and insert it into the battery hole. 3. Turn on the power and press the battery switch button for 2 seconds to turn it on. The 3 bars of the battery indicator represent the 3 gear positions (all lights are at the highest level). 4. Adjust the temperature. When the battery is on, lightly press the switch key to adjust the temperature of the socks. Infrared Heating Two infrared carbon fiber electric heating elements are built into the front of the socks, and the area around the heater warms up in 5 seconds, providing high heating efficiency by directly warming with the electric heating elements. Warming the entire front of the foot from the cold floor can maintain metabolism and stimulate blood circulation, preventing overall body chills. Unisex The electric socks use a material with good elasticity, with a maximum stretch of about 32cm, fully protecting your feet, and are unisex. If you don't use the heating function, they are also suitable as ordinary cold-weather socks. Washing Instructions 1. Before washing, be sure to remove the battery and insert the battery cable into the battery pocket (note that the battery cannot be washed). 2. The water temperature should not exceed 50 degrees Celsius, and do not wash the heated socks in a washing machine to ensure they can be used for a long time. 3. It is not recommended to dehydrate in a washing machine, dry in a dryer, or dry at high temperatures. Do not use an iron. ※ Only tried on once.
