Innovative graphene heating material: This heating pad uses a graphene film as the heating material inside, which can change the wavelength of heat to achieve deep penetration. Deep penetration heat: Achieve lasting relief by adding an industry-leading graphene fabric layer. Infrared wavelengths of 10-12μm allow heat to penetrate deeper muscles and joints. Far infrared technology is ideal for pain relief, helping to relieve tension in various muscle groups while relieving muscle spasms and accelerating blood circulation. LED controller: Personalize your treatment. The ergonomic LED controller features 6 heat Settings, from warm to high, available according to your needs. Our back heating pads are designed to relieve back pain and feature a precise temperature control system with three timer Settings (1, 1.5, 2 hours) that automatically turn off after two hours. Versatile and reliable: Made from unique embossed printed mink and soft fleece fabrics, it offers a stylish option. You can use it in the office, on the couch, in bed, at home or at the gym. The versatile design of our heating pads can be used comfortably on the shoulders, neck, joints, waist and abdomen. Reliable Choice: Safe and reliable, our heating pad with auto-off function has passed multiple safety inspections and manufacturing standard tests, including compliance with the UL130 standard. Your safety is our top priority and we ensure that our heating pads meet quality, health and performance standards. Fast heating: Fast and stable heating, 122°F for 12 minutes, 140°F for 20 minutes (up to 149°F), reaching the industry leading level. The use of PTC/NTC hot wire provides the perfect temperature, allowing you to enjoy a relaxing experience, while ensuring overheating protection.
