*********** REPLY SEPARATOR *********** John; It's continous. But the components in the power supply only accept what they can manage or what they're rated for. The battery keeps this feed stable, and as a basic nature of electricity, only supplies what is needed at the time. Since it's a battery after all, it simply continues to store whatever is available until needed, and is constantly recharged by the wall outlet. So in a way, you could say that it is "Continous Stepping" that occurs, whereby the battery is the only source of electricity to the computer, but it can step up (or down ) the watts or amps to respond to the needs of the computer at any particular time. In any case, it acts as a buffer between your PC or electrical device, and the variable power that your power company can provide. If I could remember all my electrical theory from college, I'd be able to give you the in depth nuts and bolts. Lanman
