[Soekris] Power consumption of 4526/4826

I'm running 2 4526's off a solar powered setup. Each has 2 Wireless cards in
it and they seem to use about 300mA each at 12.5V. That's based on the solar
I don't think the power of the wireless card makes much of a difference, one
has 200mw cards in it, and at 12V that is only 10mA. I haven't seen any big
difference in battery usage due to traffic. But I'm only probably putting 10
gig a month over them as that's my internet connection cap.

It depends a lot on how much work the CPU has to do and it depends
a lot on the transmitted power of the wireless cards.
I have been trying to measure some "typical" numbers in order to
give people som "rule of thumb" numbers to go from, but it is
tricky to get some measurements than have actual meaning.

Never attribute to malice what can adequately be explained by incompetence.
