The Heated Knee Brace is designed to combine knee support, wearable comfort and convenient heating in one practical and easy-to-use design.
Its wraparound brace structure helps fit securely around the knee area, providing a comfortable and supportive wearing experience for daily use. The integrated heating function delivers gentle warmth to the knee, helping create a more comfortable feeling during colder weather or whenever extra warmth is needed.
A key feature of this product is the magnetically detachable battery positioned on the outer side of the knee. This removable battery design makes daily use more convenient, allowing the power unit to be attached or detached easily when needed. It also supports portable use, so the knee brace can continue providing warmth without requiring a fixed power connection.
The brace is designed for easy wear and adjustment, helping it stay comfortably in place during normal daily activities. Its portable and user-friendly design makes it suitable for use at home, in the office or while moving around during the day.
Simple, functional and comfortable, the Heated Knee Brace is a practical choice for users who want both knee support and soothing warmth in one wearable product.

Yes. CNT film is die-cut to any 2D profile, and electrodes are routed to your outline — no tooling cost for most shapes.
Wearable builds use detachable controllers and sealed film, allowing hand or machine wash of the fabric assembly.
Dual protection: NTC closed-loop regulation plus an independent hardware cut-off, with an auto shut-off timer.
Full private label: logo, manual, colorbox, barcode and FBA-compliant cartons prepared to your brand guidelines.
Functional samples ship in 7–10 days; sample fees are credited back against your first bulk order.
