Standalone small sci-fi energy cell prop, rectangular and compact. Futuristic but heavily decayed. Dented metal plates, exposed wiring, corroded connectors, faint panel seams. Several missing screws, chipped edges, and small surface fractures. No environment. No floor. Floating single object only. Design suggests it once stored power but is now nonfunctional. Subtle asymmetry, believable wear, layered mechanical detailing.
