Step 1: Supplies
-Truck, car, van, riding lawnmower (no, I'm not kidding, some of them actually have 12v sockets!), etc.
-Battery jump starter/ battery booster pack/ rechargeable 12v battery thing (with cable to charge in car)
-12vdc to 120vac power inverter (mine is only 200watts)
-Lights, chargers, other things that use power (must total less that inverter's output, watts=volts x amps)
Total cost should be about $25,000, or only about $15-40 for inverter and jump starter.
