It is ironic that USB be an acronym for Universal Serial Bus (Universal Serial Bus), but it has very little universal. Not only are there a multitude of different connectors, but they also come in different colors, and not all of them are compatible with each other. Do you know what purple USB is?
The first USB 1.0 and 2.0 cables had a metal connector, with the plastic part in black. The color we all know is the bluewhich was released to indicate that both the cable and the connection are USB 3.0.
And from here, things have gotten a little out of control, since we can find purple, orange, red or green USB cables. A real gibberish.
What the colors of the USB ports mean
The first thing to know is that most of these colors are commercial in nature, they are not part of the standard. They all work like USB cables, but these colors offer charging capacity information, so it’s important to know them.
According to account BGRboth the purple USB connectors like the turquoise (teal) means it is a connector or cable USB 3.1. If it is also from the Huawei brand, it indicates that It is compatible with its SuperCharge fast charging.
We also have the redwhich reminds you that you can charge your mobile on a PC, even if it is turned off.
And orange USB from Huawei means that it works for Fast Charging, the method before SuperCharge.
Finally the green USB have been adopted by Qualcomm for its Quick Charge fast charging technology.
It must be taken into account that both SuperCharge and Quick Charge are proprietary technologies, that is, they work with their own cables. A SuperCharge cable may be able to transmit data on a generic device, but it will not have fast charging. Likewise, a generic cable will not activate fast charging on a SuperCharge or Quick Charge device.
If you use these fast charges, make sure the cable is compatible before purchasing. It doesn’t have to be those colors, some manufacturers don’t use them, they prefer generic colors.
One more example that IT standards are very far from being a standard.…This has been the case since the first PC.
