This Recommendation defines the requirements@ and provides guidelines on the environmental aspects@ of universal power adapter solutions (UPA) designed for use with portable information and communication technology ICT (ICT) devices. UPAs covered by this Recommendation are those that are used with the devices with voltage and power levels identified in clause 7.1.1. This Recommendation does not cover UPAs defined in [ITU-T L.1000] and [ITU-T L.1001]. This Recommendation provides requirements and guidelines for energy efficiency and no load power. It aims to reduce greenhouse gas (GHG) emissions to optimize the use of scarce and raw materials and to enable a long product lifetime to reduce e-waste generation. The considered UPA does not provide any charge control for rechargeable batteries. The load full charging function in the portable device@ if present@ is not within the scope of this Recommendation. This Recommendation describes basic configurations and general requirements for UPAs and their interfaces@ including cables@ connectors@ voltage@ current@ ripple@ noise@ energy efficiency@ safety@ electromagnetic compatibility@ resistibility and eco-environmental specifications. Market issues associated with: counterfeit products or untested combinations of ICT devices and UPAs are not within the scope of this Recommendation.
