Wall wart plugs

Group:

Like most folks, I seem to have a plethora of wall transformers. They all
have different output (low voltage) plugs, but these plugs do seem to have a
lot of commonality. Can anyone point me to a definitive (or nearly
definitive) list and specification of the different types of output plugs
used?

Thanks

There ain't no such thing .. I've seen up to 6 pin connectors used for 5
voltage wall warts and I doubt if that's even the record.

Actually there are good reasons for keeping someone else's wall wart out of
my input plug unless there's a very good match between polarity, voltage and
current supply. I certainly wouldn't want a center negative, 18 V AC
adapter plugged into my label printer that expects 5V DC with center
positive.

There certainly aren't a sufficient variety of connectors for all of the
different polarity, voltage, current combinations available so we'll
probably never see a standard emerge despite a real need for it. To see the
variety of available combinations, look at one supplier's list of 143 DC
output wall warts at

Unfortunately there are no standards at all so it's a hit-or-miss
proposition as to whether a foreign adapter will mate with a piece of
equipment. Usually as soon as I get one, I create a label that indicates
what equipment it goes to.
