The Sparker is a compact, handheld device resembling a futuristic lighter with intricate mechanical details. Its body is primarily metallic with a brushed steel finish, featuring a cylindrical shape with a slightly tapered end where a small, blue energy emitter is located. The surface is adorned with faint glowing circuit-like patterns that pulse softly, indicating its charge status. A rugged, rubberized grip wraps around the middle for secure handling, and the device emits a subtle hum when activated.
