How do I turn on my Kelvin Jacket?

Once your power bank is charged, the battery should be plugged into the jacket from the cord located in the inside left pocket. If you are using the red and black 7.4v (X3) battery you will need to turn the battery on as well. All other batteries do not require it. The jacket is turned on by pressing and holding the logo located on the chest of the jacket. This button should be pressed down for several seconds until the light turns on. You can then cycle through the heating levels by pressing the button lightly.

Depending on model:

Red or Blue - High

Blue or Teal- Low

Green - Eco

To Turn off your jacket, press and hold the logo button on the chest of the jacket until the light turns off.
