Using this USB heating hat is easy. Just connect the hat to a 5V power source via the included USB cable. You'll start feeling the warmth soon as it heats up to 40 - 50 degrees. When you're not using it, unplug the USB cable and store it in a dry place. Be careful not to wash the hat in water as it may damage the heating module. If the hat gets dirty, you can gently wipe it with a damp cloth. Also, don't expose it to direct sunlight for a long time to avoid color fading. With proper care, this hat will serve you well for a long time.
