The successive laws mandating higher average efficiencies in external power supplies have undoubtedly had a significant impact on global power consumption over the past decade. However, ensuring that your external power supply is up-to-date with the dynamic regulatory environment has become a complex task.

The DOE works to develop new sources of clean energy, reduce dependence on foreign oil, promote energy efficiency, improve the security of the nation's nuclear stockpile, and promote scientific research. It also works to protect the environment by reducing greenhouse gas emissions and promoting renewable energy sources.

When the United States Department of Energy (DoE) implemented its Level VI standard in February 2016, most OEMs were forced to update their designs to meet these requirements. Now with even stricter regulations proposed to become law in the European Union (EU), companies that ship an external power adapter with their end product must yet again closely monitor the regulatory environment to ensure that they are in compliance.

The below is this infographic with the goal of simplifying for you the where, when, and what of the current US DoE Level VI standard and the upcoming EU CoC Tier 2 regulations.
