15A is *way* too much to be drawing with a cigarette lighter adaptor. The
socket can handle that much. The wire may be able to handle that much. BUT
the adaptor itself will soon self destruct under such heavy use.

The usual thing that happens is the *spring* that pushed out the "tip" to
make the electrical connection in the center of the jack can't handle all
that current. Remember, ALL the current flows thru that spring on the way
to the wire and your radio. It heats up the spring and failure soon
follows.

How much current/time for this to happen? I dunno .. 15a, sure .. 10a,
maybe ... 5a not likely.
