Following close on the heels of last week’s finalized energy efficiency standards for metal halide lamp fixtures, the US Energy Department yesterday announced the final rule for new efficiency standards for external power supplies.
The agency says external power supplies, commonly referred to as “wall warts,” are used in hundreds of types of electronics and consumer products, including cell phones, tablets, laptops, video game consoles and power tools, to convert power from a wall outlet into lower voltages. More than 300 million external power supplies are shipped in the United States each year and the average American home has five to ten external power supplies. These numbers are expected to continue growing as consumers and businesses purchase new types of personal electronics.
