[NANOG] Re: Small Capacity UPS

Yeah, it's a shame how many electric toothbrushes I've had to throw out
when the batteries go bad. Good brands also, but they don't make them
serviceable.

Since I'm in a hurricane zone, I have flashlights with 18650 cells. more
cells than flashlights. Worst case scenario is that I can't get gas for the
generator and the power is out for a week or whatever (and if you read my
previous posts I'll solve that problem soon) I can charge batteries from my
off grid backyard solar.

My current problem is that comcast/xfinity goes out more than the power
flickers. I can't wait for buried fiber on my street to come one day.
