Well, actually, I can, because the wallwart puts out 12VDC and the
cap would be across that 12 volts. I agree with one poster that
measuring the current and then calculate the time gained by a
particular cap. But, I think I found the real reason. I think it's
the ISP.
I'll post more later.

The ISP?

How does your ISP know when power goes off at your house?


Well, out here in the country, there are very few feed lines. So,
if I loose power at my house, chances are, the remote switcher will
also loose power. If the batteries are not good, the site will (and
has) go down.

All the telco remote terminals I've seen have a transfer switch and
connection for a generator. The issues are how long with the poorly
maintained batteries last and how quickly will the telco dispatch a
truck with a generator to the site. I've seen a few larger RTs that do
have permanent standby generators, but most do not.
Yah, under Verizon days, we had a long phone outage on a Friday in
the morning. It went on until about 9:30PM when V brought a
portable generator and restored power. Even after commercial power
was restored the next day, the generator stayed there for about 2
months. I think a big company in the industrial park must have
squawked. Imagine not have phones all day on a Friday, even. I
don't know this for sure, but, I'd bet V left the generator there
until they installed new batteries, just to appease that large
company. Then again, knowing V, they probably just never bothered
to pick it up and bring it to there storage facility!
