That's roughly what seems to be taking over the space under one of my
workbenches.

Hi Jeff, I did find one good use for the 5 volt mini usb phone chargers. The
wife bought some LED window candles this past Xmas, they use 3 "C" cells
_each_(!) So I used the phone charger to power all three of them in our
living room front windows. 30 minutes of work saved me a ton in battery
expense.

Those are wall warts that are not attached to specific pieces of
equipment. The cardboard boxes on the right are full of sorted and
tested wall warts. There are two more boxes of wall warts that I
didn't feel like dragging over for the photo. Add another 4 large
boxes at home and a small box in the vehicle.
Time for a purge.

I have a drawerful of them. Most are Sony 455s. * (Or is it 445? I never can
remember.)
The "obsolete" ones can come in handy. For example, a Sony 9V Discman supply
does a great job running my Brother label printer.
PS: Speaking of Brother labels... They're a great (though pricey) way to
label stuff, but they have an Achilles heel -- they simply won't stick to
polypropylene. (I've complained to Brother about this.) After a few minutes
on my trash can, or those nice plastic binders from Staples, they start
"unwinding". Magic Mending Tape is needed to hold them down.
The preceding is an example of free association.
* Sony produced an elegant little universal switching version of this
supply. I bought a box of 'em on eBay. I use one of them to power a pair of
STAX electrostatic earphones. (Really.)

I try to keep no more than 1 adapter of each voltage and sex even
though it kills me to throw extras out. We have an area-wide garage
sale each summer and I donate as much as I can to that, otherwise my
basement would sink even further into the ground.

Yeah, I noticed. Looks like your topic stabilizer circuit is drifting
out of control. The usual culprit is too much positive feedback and
agreement, which tends to destabilize any feedback circuit. With
enough positive feedback, it could easily become oscillatory, or latch
at either extreme position. I suggest you add some negative feedback
or criticism, which should prevent any further off topic excursions.
Also, be sure to check for cranial overheating which is a good
indication of bugs in the system.

I just crack them open, replace the usual bulging electrolytic, and
live happily ever after.

The biggest problem is opening the plastic case. Sometimes, it's easy
(using a bench vise). Other times, it's impossible.

On a slight tangent: Does anyone make a power strip with outlets
spaced to hold multiple wallwarts?

I feel your pain. I feel more pain when I throw away something that
can be repaired. When I visit the local recycler, I'm often shocked
at all the easily repairable stuff that gets tossed.
One method I like is to use a mason's chisel. I place it along the
glue line and LIGHTLY tap the chisel with a hammer. The glue joint is
quite brittle. With luck, you'll hear it crack open. If that fails,
a hack saw will always work. However, that's a mess to re-glue, and I
have to cover the damage with some decorative trim tape.

Belkin makes a line of large, two row, power strips that should work.
There are also clones. One of them has a rotating power jack that
will work with either orientation wall wart plugs.
<http://www.homedepot.com/h_d1/N-5yc1v/R-100663212/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053>
I use these:
<http://www.belkin.com/IWCatProductPage.process?Product_Id=199275>
<http://www.homedepot.com/Electrical/h_d1/N-5yc1vZarcd/R-100663223/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053>
which are expensive, but also repairable and indestructable. I've had
plastic power strips almost catch fire when the MOV gets hot, and
therefore prefer metal cases. If you need to fit a strange wall wart,
just add one of the numerous right angle or 6 jack adapters.

Cyberguys sells an "extendable" power strip (112 0179) and a PowerSquid (121
1275 & 121 1291).

You can also get cheap AC extender cables.

If you have not yet discovered Monoprice, do so. It has all kinds of
cheap-but-good stuff.

Always check under any paper or mylar label for a recessed screw holding
the clam shell halves together.
Too, placing the wall wart in a freezer for 10-15 minutes will make the
solvent-glued seam even more brittle and readily crack-able-open-able.
I employ a used 3/4" wood chisel bought at a second-hand store -- found
in the ever present used-and-abused tools bins.
