Can not feel the heat.

There is a 3-5 minute pre-heat process after you turn on the coat. During this time the light will blink red. Please switch the setting to high-temperature setting (red light) and allow the jacket to heat for 15-20 minutes. Touch the 3 heated area (left/right chest and back) from the inner part of the coat to see whether you can feel the obvious heat.

If not, please contact us at
