Why some USB ports are purple (and why they're rarely sold in the US)
USB port colors, particularly purple, are often used by manufacturers to indicate fast charging and data transfer speeds, though these colors are not officially standardized by the USB Implementers Forum (USB-IF). While white, black, and blue have official meanings for USB 1.0, 2.0, and 3.0/3.1 respectively, other colors like purple, orange, and green are manufacturer-specific. Purple is commonly associated with Huawei's SuperCharge system, offering speeds of 40 watts or more, and is also sometimes used by other brands for USB 3.1 Gen 2 cables to denote higher data and charging capacities. The rarity of purple ports in the US is partly due to trade sanctions affecting Huawei's ability to sell products there. AI
