The idea is that a user plugs the device into the mains via a 60-W adapter, which brings eight low-power IR LEDs to life, quickly raising "the temperature by 10 °C in front of it. The LED spots then direct the heat as kind of parallel beams, each not strong enough to do any harm. It offers six heat options (30°c, 35°c, 40°c, 45°c, 50°c, and 55°c) which you can easily swap between by tapping one button.

Outdoor performance: We affixed a Bluetooth temperature sensor onto each device, set the sensor to record data in 1-minute intervals, and wrapped it in a towel to simulate conditions inside a jacket pocket.
