External power adapters, also known as power supplies, are crucial to the operation of virtually all small electronic devices. As many as 1.5 billion are in use in the U.S. - that's about five for every person. The total electricity flowing through all types of power supplies is about:

• 300 billion kWh/year, and
• 11% of the national electric bill

They convert high voltage ac electricity from the wall outlet to the low voltage dc power used to power electronic products, like the D-Link networking products shown on this page.

Earning the ENERGY STAR

An adapter that has earned the ENERGY STAR meets strict energy-efficiency guidelines set by the US Environmental Protection Agency (EPA) and the US Department of Energy (DOE).

• On average, 30% more efficient than conventional models.
• Are often lighter and smaller in size, which makes it easier for consumers to transport products like laptops.

Consumers are now able to purchase a growing variety of products that are packaged with ENERGY STAR qualified power adapters. Products with qualified adapters are identified with a special version of the ENERGY STAR label.
