About the Power black filled icon
A long zigzag lightning bolt runs diagonally through a circle whose stroke breaks where the bolt passes, so the two shapes interlock instead of overlapping. The pairing reads as electric power, energy supply and speed rather than a plain on/off switch. Useful for power and energy settings, charging screens, utility dashboards, electrician websites and product badges for high-performance hardware.
The bolt is tall and narrow with sharp angled tips reaching past the ring, while the circle is left open at two points to give the mark depth. It sits alongside battery, plug and flash icons in the same stroke weight. Keep at least the bolt visible when scaling below 24 px.
This is the solid black filled version of the power icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
