I recently read about a company that will be introducing a series of micro-sized power converters that will attach to a computer's USB port and charge general purpose rechargeable batteries. The logic is that USB ports are ubiquitous, people who have computers typically also have several applications for rechargeable batteries, and the mess of multiple dedicated wall-wart chargers can be eliminated. I realize that this isn't new regulatory territory, but it is a novel use of the USB concept. OTOH, is there anything in the USB definition that addresses RF noise and transients on the USB power bus? Is there a CE/CS USB criteria?
