Have you ever hear Efficiency Level Ⅴ or Ⅵ from your customers or power suppliers? “Yes, of course”, and I know that’s your answer hhaa. But you might didn’t get it fully, here this article is going to simply explain to you what is the DoE Level Ⅵ.
Simply give you a simple conclusion below.
DoE is a department of US Government, who is in charge of energy and has the right to establish energy-efficiency standards, There are Energy Efficiency Level from Ⅰ to Ⅵ, higher level number means better energy efficiency. And Level Ⅵ is normally for the external power supply, showing to best energy efficiency. If an electronic product tells it’s energy efficiency DOE level Ⅵ, then it’s the best. So DoE level Ⅵ means the external power supply has good energy efficiency, and it’s the best for now.
What’s DoE？
DoE is the short name for United States Department of Energy, which is in charge of U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. It has right to establish energy-efficiency standards for certain appliances and equipment, power supply is one of the equipments.
The equipments include:
CONSUMER PRODUCTS
COMMERCIAL AND INDUSTRIAL PRODUCTS
LIGHTING PRODUCTS
PLUMBING PRODUCTS

What is DoE the Energy Efficiency Standard for external power supply?
According to “U.S DoE CFR Title 10: Energy PART 430–ENERGY CONSERVATION PROGRAM FOR CONSUMER PRODUCTS, Uniform Test Method for Measuring the Energy Consumption of External Power Supplies” Following is the Performance Requirement of Internation Efficiency Marking Protocol for External Power Supplies from DOE Level Ⅰ to Level Ⅵ.
In a word, DOE level Ⅵ is the highest energy efficiency Level for external power supply in the world.
