6. Page 6 May 2010 www.chinattl.com China Telecommunication Technology Labs ITU-T Recommendation L.1000 Summary Provides high level requirements for a universal power adapter and charger solution that will reduce the number of power adapters and chargers produced and recycled by widening their application to more devices and increasing their lifetime. Also aims to reduce energy consumption. The longer life cycle and possibility of avoiding device duplication reduces the demand on raw materials and waste. Designed to serve the great majority of mobile terminals and other ICT devices.
