OT: AC/DC adaptors

[Eric Cope]

Make sure they are AC/DC adapters. Some are AC/AC adapters. Also make sure
the plug is properly polarized. Some plugs the inside is (+) and the outside
is (-), some are switched. Make sure the current rating (mA or A) is greater
than what you need. Make sure the voltage is the same.
