Product Features
- Far Infrared Heat: Graphene heating elements provide gentle, uniform heat to the lumbar area, effective even over light clothing. Its gentle and constant temperature relaxes lower back muscle tension without irritating or damaging the skin.
- Ergonomic 3D Lumbar Support: The contoured 3D backrest and double elastic straps help the pad conform better to the back's curve and concentrate heat and vibration in the lumbar area.
- Wireless Operation: A large capacity 5000 mAh battery allows continuous operation for almost 2 hours, even with both vibration and heat modes activated simultaneously.
- Adjustable Belt: This heating belt includes a 60 cm extension, with total dimensions of 170 × 20 cm, allowing it to fully cover the lumbar area and adapt to waist circumferences between 70 and 170 cm.
- Customizable Settings: This lumbar massager combines heat and vibration massage functions with 3 temperature levels and 3 freely combinable vibration modes. Its bilateral vibration design distributes pressure evenly on both sides and reduces strain on the spine.
- Double Safety Features: Features an intelligent NTC thermistor for precise and constant thermal regulation, along with a double protection system that cuts power in case of overheating. It includes an automatic shut-off after 30 minutes.
Setup
- Charge the Battery: Before first use, fully charge the external 5000 mAh battery using the provided USB cable. The battery indicator lights will show charging status.
- Attach the Battery: Connect the fully charged battery to the heating pad's power port.
- Position the Pad: Place the heating pad around your lower back. Ensure the contoured 3D support aligns with your lumbar curve.
- Secure the Belt: Wrap the main belt around your waist and fasten it. If needed, use the extension belt for a comfortable and snug fit. The belt should be firm but not overly tight.
- Adjust for Comfort: Pull the double elastic straps to further adjust the fit, ensuring the pad is securely in place and the heat/vibration elements are in contact with your lower back.
