Summary - L.1004 (07/2025) - Universal fast-charging solution for mobile terminals

Recommendation ITU-T L.1004 is applicable to the universal fast-charging solution (UFCS) for mobile and wireless devices. This Recommendation defines the overall framework of the solution for mobile terminals and the role of each part. The communication flow between each part of the UFCS and the key functions in it are also described. The Recommendation specifies requirements for various aspects such as system, safety, electromagnetic compatibility, material, eco-environment and energy efficiency. The higher interoperability brings important environmental benefits including reduced electronic waste and use of materials and energy, a smaller carbon footprint through lesser use of energy and materials to produce chargers and being able to sell devices without a charger.
