I had a cheap generator. I plugged in an extention cord through the window, into a powerstrip with the fridge, modem and 2 sockets to charge devices. Worked perfectly when I needed it but I also had a kerosene space heater so I wasn't too concerned about freezing(bring all blankets into the living room, build a blanket fort atleast 6 feet away from the space heater and have everyone cuddle, calms people down, provides warmth and forms bonds.
