Although this color-coded system on USB ports has been around for some time, the meanings of colors like blue, white, yellow, black, and especially green have not been clearly communicated to consumers.
Green USB ports are quite common.
The green USB ports commonly found on chargers indicate that the port supports Qualcomm's Quick Charge technology. This technology allows for faster charging than conventional USB charging methods by adjusting the voltage to match the device's maximum charging speed. Additionally, some orange USB ports also support Quick Charge.
However, not all green USB ports support this technology. Qualcomm has developed several generations of Quick Charge, with Quick Charge 5 being the latest version. All generations of Quick Charge are backward compatible with previous generations, meaning users can use a Quick Charge 5 charger to charge a Quick Charge 3-enabled device, although the charging speed will only reach the level of Quick Charge 3. To achieve the highest charging speeds, users need to use a cable that supports high-speed charging.
It's important to note that there are no regulations mandating manufacturers to use specific colors for USB ports. Therefore, a green USB port may not support Quick Charge, and users should check the manufacturer's specifications to determine the port's exact capabilities.
The features that differ between green and turquoise USB drives are...
Don't confuse green USB drives with turquoise ones.
While other colors like blue have been widely adopted and standardized, green is often used to denote specific technologies of individual companies. This can be confusing, especially since green USB ports are easily confused with turquoise USB ports.
A turquoise USB port typically indicates a USB 3.1 Gen 2 SuperSpeed+ port, capable of supporting data transfer speeds up to 10 gigabits per second (Gbps). However, this port does not support fast charging speeds like Quick Charge. If users confuse the two colors, they may experience slower-than-expected data transfer speeds, increasing file transfer times.
Therefore, when checking the USB ports on your device, be sure to clearly distinguish between the green and turquoise colors to get the most out of your device.
