The icon is shaped like a square with curved corners. Inside of it is a circle that takes up half of the square. Inside the circle are two dots, one at the left center and the other towards the right center.
This is a Wall Socket icon. We've made it in iOS style
, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 13,300 icons, all in the same style and quality.
