This is a USB Mini 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 12,800 icons, all in the same style and quality.
This icon represents a usb mini A. It is a small flat rectangle with the corners off coming down into a triangle shape at the bottom and flat edges at the top. This rectangle has five small lines across the middle.
