It's a little hard to tell for sure, bu it looks to me as if the colors are reversed on the extension cable, but the wiring goes straight through from male to female plugs,
so the wire connection is still correct if used as is for an extension... only the colors of the wires are reversed.
So if you don't cut the extension and wire to something else, counting on red to be + and black to be -, there should be no problem. If you read the user comments in the HK product page, they seem to confirm. Maybe some one here has some of the extensions and can confirm?
