Power Dissipation

the process by which an electronic or electrical device produces heat (energy loss or waste) as an undesirable derivative of its primary action.

1W

Output Current

The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.
