Subject/title: External universal power adapter solutions for portable information and communication technology devices
Summary: This Recommendation defines the requirements for a universal power adapter solution (UPA) designed for portable ICT devices. It is complementary to [ITU-T L.1000] and [ITU-T L.1001] and aims to cover the widest possible range of ICT devices for portable use within the defined voltage and power ranges. It firstly describes the UPA basic configuration, consisting of a power adapter block with a detachable input cable and a detachable output cable to the ICT device. Then, different general requirements for the UPA and their interfaces, including cables, connectors, voltage, current, ripple noise, energy efficiency, no load power, safety, electromagnetic compatibility, resistibility and eco-environmental specifications are defined. All the requirements have been set with the aim to reduce the e-waste and increase the usability. This Recommendation intends to complement and to make use, as far as possible, of what defined in IEC/Technical Specification 62700/Ed1.
Comment: Universal Power Adapter for portable ICT equipment - Phase 2 of L.1000 (External Common Power Supply for portable ICT equipment) - previously called L.CPSportable provisionally to become L.1001
