Select from three manual heat settings

- The medium setting offers 113°F or 45°C of heat for 7-9 hours.
- The high setting offers 70°C or 158°F of heat for 4-5 hours.

The length of heat depends on your heat setting, the amount of charge you have, the age of the batteries, and the outdoor ambient temperature. Here's a tip to extend battery life. Reduce the heat by a setting if your toes are warm and turn the batteries off when you take a break or stop for lunch.
The Therm-ic app features..
- The free Therm-ic app works on Android and iOS phones that have a Bluetooth connection.
- If you forget your phone, the batteries can still be operated manually with the touch of one button located on the batteries.
- Select from 10 heat settings with the app. Plus there's a pause setting that allows you to save battery power.
- The app allows you to determine the maximum heat setting for a period of time. Example; If you think you'll be outside for 4 hours, you can set the batteries to deliver the maximum heat for the 4 hours before dying out.
- The Motion Control mode allows you to manage your batteries to your activity. Example, you can choose to lower the heat setting level by -1 when you are moving. Then go back +1 when you're still. This extends battery duration.
- The ECO mode allows you to conserve battery duration by allowing you to choose to alternate between 9 minutes of use, then 2 minutes of standby.
