This Naładowany akumulator icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
The icon is shaped like a rectangle with curved edges. The right side of it has a small rectangle indent poking outwards. Inside the rectangle there are 6 lines equally spaced starting from the left and stopping a little more than half way.
