IEC 62700

From Wikipedia, the free encyclopedia

IEC Technical Specification 62700: DC Power supply for notebook computer is an IEC specification of a common standard for external laptop computer AC adapters. Laptops and AC adapters following this standard will have interchangeable power supplies, which will enable easy reuse of used power supplies (thereby reducing electronic waste) and make buying a new compatible power supply for a laptop simpler.[1][2]

The specification was published on 6 February 2014.[3]


Despite being an industry open organization with open participation, the standard has been criticized by some[who?] for not being openly available for review.[clarification needed] Some alternatives include:
