Abstract
An extension cord with AC and DC output, includes a first conducting line coupled to a positive end of a DC source and a first end of an AC source, a second conducting line coupled to a negative end of the DC source, a third conducting line coupled to a second end of the AC source, a first socket, and a second socket. The first socket includes a first node, a second node a third node respectively coupled to the first conducting line, the second conducting line, and the third conducting line. The second socket includes a fourth node, a fifth node and a sixth node respectively coupled to the first conducting line, the second conducting line, and the third conducting line. The second node floats when the first socket is provided with the AC output. The third node floats when the first socket is provided with the DC output.
