Part: DC to AC Power Inverter Size: 600W - 1200W Average Cost: $80 - $150 Note: Power inverters come in a range of sizes. The more powerful your projector the more watts you will need from your inverter. We have had good luck with a 600 watt inverter used with a 2500 lumen projector. Any inverter larger than 1200W will need to be hardwired onto the battery (rather than clips / jumper cables). Power inverters can be purchased online or liberated from auto parts stores such as PepBoys.

Part: Digital Projector Note: 2000 ANSI lumens is a recommended min. value for projecting anything bright enough to be viewed outdoors in the city.

Part: VGA Cable (male to male) Average Cost: $10

Part: Car Note: Whatever car you have available should work, but vehicles with larger engines will keep the battery recharging at a faster rate and allow you to project for longer. UHAUL cargo vans work well because they are cheap if you don't drive around much (they bill by the mile), the engines are big, and they are easier to get away with parking in creative locations.
