Which, at the proper abstraction level provided by this class, means that it allows one to switch on or off a power supply channel. Laptops let one do this with their batteries, too. It is the same thing. I didn't check if the class comes with an attribute for "enable/disable this power source", but if doesn't, we need to add one: it *is* a generic and widely used capability in laptops, and according to you, also on PDAs. -- "One disk to rule them all, One disk to find them.
