I'm not sure the right terms to use but here is my quest. I want something inexpensive to use when the electric goes out. I do not want it connected to the house permanently as I rent and plan to move when it's possible. I want to connect my wifi modem, a fan and able to charge phone. Don't need lights as enough comes in through the windows from neighbors power plant and Texaco across the street. I can't use a gas power thingy as I don't have a place to put it safely outside. Any ideas? Remember, I have very limited funds.
