Abstract
A power adapter equipped with line winding function comprises an adapter body and a line winding means. The adapter body includes a housing and a conversion circuit held in the housing. The housing has a coupling side substantially in parallel with the conversion circuit. The coupling side includes at least one first coupling portion. The line winding means includes a first conducting line end and a second conducting line end that are extensible or retractable and electrically connected. The first conducting line end is extended into the housing to form electric connection with the conversion circuit. Hence the first conducting line end can transfer electric power from the conversion circuit to the second conducting line end. The line winding means further has at least one second coupling portion which is separable or latchable with the first coupling portion through forces. By coupling of the first and second coupling portions the line winding means can be coupled on the coupling side so that the adapter body and the line winding means are coupled to become a portable power adapter.
