There are 4 wires inside a USB data cable — red, white, green, and black. They represent power positive, negative-voltage data line, positive-voltage data line, and ground.

HDMI Cable Hot Plugging
TECH FAQ

Can an HDMI cable be hot-plugged?

While HDMI supports hot-plugging in theory, it carries high-speed digital signals that can produce electrical sparks. To ensure absolute device safety, hot-plugging an HDMI cable is not recommended.

Data Cable Lifespan Factors
QUALITY & LIFESPAN

What are the fatal factors that affect a data cable's lifespan?

The main factors include insertion/removal cycles that cause poor contact, cable bending that fatigues the copper core, and connector rusting measured by salt spray tests.

Type-C Cable Trends
INDUSTRY TRENDS

What's the future trend for USB Type-C phone cables?

USB 3.1 Type-C cables offer faster charging up to 100W, higher transfer speeds up to 10 Gbps, display output support, and broad universal compatibility.

Cable Rust Prevention
MATERIAL ANALYSIS

Why does the USB cable connector rust not long after use?

A connector's tendency to rust is directly related to the electroplating layer on the connector. This resistance is graded using salt spray tests ranging from 8 to 48 hours.

Cable Usage Tips
USAGE TIPS

What should you pay attention to when using a data cable?

Avoid yanking the cable while playing, plug and unplug correctly at the connector head, keep cables organized, and ensure your hands are dry to prevent oxidation.
