When Luke breaks out camp his first night on Dagobah, he sets out some cases and then puts a glowing device on top of one. It looks like some sort of small heater, but someone on a forum said it was a power unit. I did a few quick searches but couldn't find anything about the prop. I did find a good screenshot, though. I've circled the device I'm asking about.

What is this small heater-looking unit supposed to be?

    The heater-looking object turned out to be a... heater? Sep 8, 2017 at 23:06
  • Hah. You and Valorum in cahoots? ;-) No offense, but I always thought this one was incredibly obvious. Sep 9, 2017 at 6:03

This is a Fusion Furnace. In addition to creating heat and light, it can also be used to charge a droid.

“You ready for some power?” Luke asked Artoo, who was patiently waiting for his own form of nourishment. Luke took a small fusion furnace from an equipment box and ignited it, welcoming even the tiny glow thrown off by the small heating device, then took a power cable and attached it to Artoo through a protuberance that roughly resembled a nose. As power radiated through Artoo’s electronic innards, the stout robot whistled his appreciation.

Luke had retrieved a box of emergency provisions from his X-wing and set up his camp in a clearing. As he ignited a compact fusion furnace that he’d placed on a rotten log beside R2-D2, the droid beeped at him.

“What?” Luke said. “Ready for some power? Okay. Let’s see now.” He ran a power cable from the furnace to the droid. “Put that in there,” he said to himself as he plugged the cable into R2-D2’s socket. “There you go.”
