A:Answer Thank you for your question! The Insignia™ 20W USB-C Fast Charger Kit for iPhone is primarily constructed from durable, flame-retardant plastic materials, which are standard for most electronic chargers. These materials are chosen for their safety and longevity in electronic applications. Regarding PFAs (per- and polyfluoroalkyl substances), manufacturers are increasingly aware of concerns about these chemicals. While specific material composition details can vary and are often proprietary, Insignia, like most reputable electronics brands, aims to comply with relevant safety and environmental regulations. If you have any other questions or need further assistance, feel free to ask! - Mae | Insignia Support
