About the Thunderbolt black outline icon
One angular lightning bolt fills the frame, starting with a wide flat top, folding sharply at the middle notch and tapering to a fine point at the bottom. The shape carries ideas of electricity, speed and sudden power, so it works for battery and fast-charging indicators, storm alerts in weather apps, energy and utility dashboards, performance or boost badges, and sports team graphics.
The bolt is taller than it is wide with clean straight edges and no outer container, which keeps the silhouette punchy even at badge size. It pairs with cloud, rain and sun icons for a weather set, or with battery and plug icons for power states; align it optically rather than to the bounding box.
This is the black outline version of the thunderbolt icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
