Question:   What are the technical and administrative requirements for a Vehicular Battery Charger(VBC) for cellular phones?

Answer:   A cellular phone charger is classified as a digital device subject to 47 CFR Part 15 subpart B. According to Section 15.103(a), digital devices used exclusively in transportation vehicles are subject only to our non-interference provisions (Section 15.5) and are otherwise exempt from our standards. As long as the product is not promoted for applications other than use within a vehicle, its connection through the 12 volt cigarette lighter socket is sufficient to demonstrate that a cellular charger is intended for use only within a transportation vehicle and, thus, falls under the exemption in Section 15.103(a).
