    I forgot to mention that the optimal solution is for the router to
    have its own battery. This will truly last hours. Having an UPS
    generating the mains AC voltage from a 12V battery, and then convert
    back to 12 VDC for the router, is a big waste.

    Alternatively, power the router via a 12 volt power supply with
    battery backup.

    My Wifi router/4G modem does have its own battery and will last for
    close to 10 hours. Last summer when the power was off for 6 days it
    didn't help. With my UPS I generally wait for 10 minutes before
    powering the boxes off when the lights go out.

    Wow, six days!

    Very unusual. It was a derecho also very unusual for this area. Most of
    the trees are ponderosa pines which can reach over 200' high but have very shallow root systems so they blew over, blocking roads and taking out the transmission lines. One section near my house didn't have trees but the
    power poles themselves blew down in a domino effect. It was a mess to put
    it mildly.

    It was summer so the temperature was no problem. I have a gas stove so cooking was not a problem either. I didn't have a lot in the refrigerator
    and could get ice from a store that still had power so I didn't lose anything. I could have charged the Kindles from the car like I did the
    phone but I have plenty of real books to read. I got some bottled water
    since the electric well pup was down, and could get water to flush the
    toilet from an irrigation ditch or the river. It was sort of relaxing to
    tell the truth. No internet.


    Never seen anything similar. Well... When I was maybe about 10 or 12 we
    went to my mother's village for the summer. No water at the houses (they
    had to pick it from a fountain at the plaza), and no electricity. Ok,
    they had electricity, one bulb in the main room, maybe another upstairs.
    There was no meter, they were charged by the number of bulbs. No sockets
    at all. No fridge. No gas cooker, but my mother brought one. Horses were actually used. We did #1 and #2 at the pile of manure downstairs at the stable. This would be about 1970. All this was amazing to me, I grew on
    a city.

    My father brought his 8 mm cine projector (no super 8), and connected it
    to the bulb holder. I think they were amazed, I don't recall. My father
    had shot some scenes of village life, and they saw themselves on the screen.

    Oh, and we travelled on a Seat 600.
