# Understanding Wall Plug-In Power

 

Wall plug-in power supplies have evolved since Hubbell's 1904 patent, now powering various devices. They are the most widespread sources of low-voltage power. Despite their ubiquity, many are inefficient, with 54% energy loss. This underscores the importance of energy-efficient devices. Federally compliant supplies are crucial for safety and efficiency. With increasing demand, designing efficient products is vital.

This eBook will discuss the basics of wall plug-in power, the efficiency standards they must comply with, and more to help you understand these essential and ubiquitous electronic components.
