An optional heat controller is available, and some gloves have these as an integral part.
Important note: never use two controllers to control one garment – it won’t work!
Connecting and using an optional Keis Power Controller with your Keis Heated Jacket, Vest, or Ladies Bodywarmer.
The Controller is plugged into the Keis heated garment via the connection socket within the garment's controller pocket (front left panel).
New for 2021, Keis have launched a Bluetooth Power Controller. This provides the same manual power control functions as the standard Keis Power Controller, but will also connect to a smartphone via the Keis iControl App (available for Apple and Android phones). This means you can then adjust the power setting directly from the App on your phone - controlling any garment plugged into a Keis Bluetooth Power Controller.
