Reduce e-waste from ICTs
• ICT device needs AC / DC power convertor
Normally every ICT device has at lease one power
charge, power adapter or power switch unit
• At the end of life, ICT devices and its power units
are kinds of e-waste

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.

ITU-T L.1000 Scope
• This Recommendation describes the general
requirements for a universal power adapter and
charger solution for mobile terminals (e.g. mobile
phones) and other ICT devices.
• This Recommendation includes basic configurations
and general requirements for the power adapter and
charger interface, energy efficiency, safety,
electromagnetic compatibility, resistibility, and ecoenvironmental specifications.
