The Power Coupling is a medium-sized, cylindrical device with a hyper-detailed sci-fi aesthetic, featuring a combination of metallic and polymer materials. Its surface is heavily weathered with visible scratches, dents, and carbon scoring, indicating heavy use in harsh environments. The device has a series of glowing blue energy conduits running along its length, with a central interface panel that displays a faint, pulsating light, suggesting it's still operational despite its worn appearance.
