ITU refines its Universal Charging Solution

The ITU’s standard for a “one-size fits all” universal charging solution has been updated to extend its use to a wider variety of devices and making it even more energy efficient.

The ITU says it will no longer be necessary to provide a new charger with every new ICT device.


A detachable cable with standardized end connectors will allow connection to devices including mobile phones and other hand-held devices (including MP3 players, tablets, cameras, GPS etc). This means that as well as providing power to the device, it can also be used for data transfer, thus further reducing costs and e-waste. A USB-A plug on one end of the cable connects to the power adaptor or host device (such as a laptop), and a USB Micro-B plug connects to the mobile device.


The ITU also agreed to specify a no-load power consumption of the power adapter below 0.03W which is the most efficient available today. The recommended charging current has been increased – in the range 750 to 1500 mA – so as to reduce charging time. The standard now meets the requirements of the Basel Convention on e-waste. Said ITU Secretary-General Hamadoun Touré:


“Other standards claim to be universal and energy efficient, but only ITU’s solution is truly universal and a real step forward in addressing environmental and climate change issues. This updated standard will bring the benefits of the universal charger to a wider range of devices and consumers. I am sure it will be welcomed by all ITU’s membership – 192 governments and over 700 private sector entities.”
