7.2V 5000mAh Cordless Design: This red light therapy shoulder wrap boasts a rechargeable battery (equivalent to a 3.7V 10000mAh battery). It offers up to 380 minutes of use on a full charge (with up to 90 minutes of runtime on the highest setting). The wireless design allows you to move freely during use without being confined to outlets.

94 LEDs Pro-Grade Red Light Therapy: The red light shoulder wrap features 94 lamp beads, each with visible 660nm red light and invisible 850nm near-infrared light. The 660nm red light targets surface tissues to effectively relieve shoulder pain and soreness, while the 850nm near-infrared light penetrates deep into muscles and joints, helping to relax tension and stiffness.

3D Embrace Design for a Better Fit: This red light shoulder pad is designed to fit the shape and curve of your shoulder, offering comfortable experience. It fits chest sizes from 21" to 43" (with extension strap) and arm sizes from 10" to 14". For the best wearing experience, it is recommended to watch the wearing video beforehand.

Extra & Convenient App Control: In addition to simple button control, this infrared light shoulder brace offers the extra convenience of app control. No need to worry about not being able to see the buttons after wearing it. If you prefer to use the button control, it’s recommended to power it on and select your desired settings before wearing.

Usage Tips: We recommend using it for 20 minutes daily as part of pain relief and relaxation. During the first use, you may feel localized comfort and slight pain relief. With continued use for over 3 weeks or longer, you’ll experience greater relaxation and peace of mind. Note: Wearing clothes of different colors or thickness may cause some light to be absorbed, reducing effectiveness.
