External power supplies are devices that convert household electric current into DC current or lower-voltage AC current in order to operate consumer products. 

### Subsection (u) of EPCA directs the Secretary to specify definitions and test procedures for measuring the energy consumption of battery chargers and external power supplies, after providing notice and an opportunity for comment. In establishing these test procedures, the Secretary is directed to consider existing definitions and test procedures that measure energy consumption in standby mode and other modes. In addition, subsection (u) of EPCA directs the Secretary to issue a determination, by August 8, 2008, whether energy conservation standards shall be developed for battery chargers and external power supplies. In the determination, the Department will assess the current and projected market for battery chargers and external power supplies. This assessment will include estimates of potential energy savings from technical improvements to battery chargers and external power supplies and will suggest product classes for energy conservation standards. 

### Finally, subsection (u) of EPCA requires that the Department hold a scoping workshop to discuss and receive comments on plans for developing energy conservation standards for battery chargers and external power supplies. As this rulemaking process continues, DOE will post documents here and notify stakeholders of these updates through its email distribution list.
