Personally I regard them as about the most dangerous

yet to see one with proper mains fusing, most don't have output
current limiting, and so on.One common type sold in the UK has a 4-way
cross-shapped plug on it (3.5mm jack, 2.5mm jack, 2.1mm coax, 2.5mm coax)
with separate 1.3mm coax ('Walkman' plug) and a 9V battery clip on the
same cable. It's very easy to get a short-circuited output if those
conenctors touch each other.
It's even more "fun" when the 4-way is plugged into the power jack on a
machine, and the 9V connector wipes against, say, an edge connector. Instant
fried chips, and not the edible kind.
That's pretty much how my Jupiter Ace got wrecked (and speaking of which, I
*still* haven't managed to get in touch with the guy who was *supposed* to be
repairing it....)
