Power Capsule

Prompt

Design a minimalistic icon representing a portable power source, inspired by a capsule shape. The icon should depict a sleek, rounded capsule that subtly resembles a pill, with one half colored green to signify energy, and the other half white for a clean aesthetic. Incorporate a small lightning bolt symbol on the green half to indicate charging capability. Ensure the lines are smooth and the overall design is well-balanced, making it easily recognizable and suitable for UI applications, app icons, or logos.
