Product Overview
The Graphene Heated Hand Warmer is a compact personal warming product that integrates flexible graphene heating into a soft hand-warmer structure for everyday indoor, office and travel use.
The product operates from a 5V low-voltage power supply and is available in several heating configurations. Existing PMA engineering records include a compact PI-based heating version, a short double-sided cloth-based version and a long double-sided PI-based version, allowing different heating areas and product forms to be selected for different applications.
The compact heating configuration uses a 120 × 120 mm PI-based graphene heating element with an operating temperature of approximately 62–67°C. The short double-sided configuration uses a 200 × 150 mm cloth-based flexible graphene heating element with an operating temperature of approximately 55–65°C. The long double-sided configuration uses a 500 × 50 mm PI-based graphene heating element with an operating temperature of approximately 50–60°C.
The flexible construction makes the product suitable for portable hand warming while allowing the heating structure, dimensions, textile materials, colors, branding and packaging to be adapted according to project requirements.
For B2B projects, PMA can evaluate different graphene heating architectures according to the required product shape, heating area, target temperature and customer application.
