This is a Micro USB A 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 12,100 icons, all in the same style and quality.
This looks like a rectangle situated horizontally. There's a smaller rectangle attached to the top side of the bigger rectangle, on the inside. there's a bunch of small squares hanging off of the rectangle.
