The [[International Telecommunication Union|ITU]] published Recommendation ITU-T L.1000, "Universal power adapter and charger solution for mobile terminals and other [[hand-held]] ICT devices",  which specifies a charger similar in most respects to that of the GSMA/OMTP proposal and to the European [[Common external power supply]]. The ITU recommendation was expanded and updated in June, 2011.<ref>{{cite news |url=http://www.itu.int/ITU-T/recommendations/rec.aspx?rec=11348 |title=Universal power adapter and charger solution for mobile terminals and other hand-held ICT devices|publisher=International Telecommunication Union |date=2011-06-13 |access-date=2013-03-23}}</ref> The hope is to markedly reduce the profusion of non-interchangeable power adapters.

The [[European Union]] defined a [[Common external power supply]] for "hand-held data-enabled mobile phones" ([[smartphones]]) sold from 2010, intended to replace the many incompatible proprietary power supplies and eliminate waste by reducing the total number of supplies manufactured. Conformant supplies deliver 5&nbsp;VDC via a micro-USB connector, with preferred input voltage handled ranging from 90 to 264&nbsp;VAC.

In 2006 [[Larry Page]], a founder of [[Google]], proposed a {{nowrap|12 V}} and up to {{nowrap|15 A}} standard for almost all equipment requiring an external converter, with new buildings fitted with {{nowrap|12 VDC}} wiring, making external AC-to-DC adapter circuitry unnecessary.<ref name="GooglePower">{{cite news|last=Markoff|first=John|title=Google to Push for More Electrical Efficiency in PC's|url=https://www.nytimes.com/2006/09/26/technology/26google.html|access-date=2011-06-03|newspaper=New York Times|date=September 26, 2006}}</ref><ref name="GooglePCPower">{{cite web|last=Alter|first=Lloyd|title=Google Pushes for PC Electrical Efficiency; Side Effect: No More Wall-Warts|url=http://www.treehugger.com/files/2006/09/google_pushes_f.php|work=treehugger.com|publisher=Discovery Communications, Ltd.|access-date=2011-06-03| archive-url= https://web.archive.org/web/20110717095723/http://www.treehugger.com/files/2006/09/google_pushes_f.php| archive-date= 17 July 2011 | url-status= live}}</ref>

IEC has created a standard for interchangeable laptop power supplies, [[IEC 62700]] (full name "IEC Technical Specification 62700: DC Power supply for notebook computer"), which was published on February 6, 2014.
