The Color of the USB Port Reveals the Secret: How to Recognize Data Transfer Speed.

According to inkorr.com: A small detail that most users overlook can tell a lot about the technical capabilities of the device. We are talking about the colored insert inside the USB port - blue, black, red, yellow, or another color. According to ZDNET, the color of the connector determines the generation of the interface and the data transfer speed.

Although USB ports look the same, their technical specifications can vary significantly, even if they are located on the same device. For example, two identical USB-C ports on the same laptop may have different data transfer speeds or power delivery capabilities.

Identifying USB Generations by Color:

• White - first generation USB 1.x, speed up to 12 Mbps. Used in old devices.

• Black - USB 2.0, data transfer up to 480 Mbps. Still the most common standard.

• Yellow - active even when the computer is off, allows charging devices in sleep mode (USB 2.0 or 3.0).

• Orange - similar to yellow, but supports USB 3.0 and higher speeds.

• Blue - USB 3.0 (SuperSpeed), up to 5 Gbps. The most recognized color of modern laptops.

• Teal - USB 3.1, speed up to 10 Gbps.

• Red - USB 3.1 Gen 2 / USB 3.2, up to 20 Gbps, as well as support for charging when the PC is off.

Types of USB-C Ports:

• USB 2.0 - up to 480 Mbps;

• USB 3.x - up to 20 Gbps;

• Thunderbolt - up to 40 Gbps.

The latest standard, USB 4, has already appeared in new laptops and offers data transfer up to 120 Gbps, as well as compatibility with all previous generations. Experts recommend paying close attention to the color choice when buying cables and devices, as this will affect speed and power delivery capabilities.

It is also important to remember safe methods for cleaning your smartphone's charging port.

Therefore, the colored inserts in USB ports not only decorate your technology but also serve an important function, simplifying the choice of the right accessory. Knowledge of these nuances will help users maximize the capabilities of their devices.
