There are 3 heating levels and a free 4.9-foot charging cable. A wide temperature range from 45 - 65 °C, which can be easily changed with a button. The temperature can be set from 104 °F to 140 °F. We recommend using the electric lumbar support for hot therapy during the day. The electric heating belt provides ultra-comfortable heat for back pain, muscle soreness, relief of cramps, lack of exercise and keeps the waist warm.
