Powering a backyard movie night
The projector is most of the load. Epson's Home Cinema 2350 is rated at 280 watts, so a 2.5-hour movie uses about 700 watt-hours.
What the Epson says
For US-style 100 to 120 V power, Epson rates it at 280 W in standard mode and 242 W in ECO mode. Two documents agree on both numbers.

Speakers, a laptop or streaming box, and a screen blower all add to this. Enter them in the sizing tool with the numbers from their own stickers.
