Device support depends on USB-C features like power delivery or alternate modes for video output.

Common Myths

Many people have wrong ideas about USB-C. These myths cause confusion when buying cables or devices. Knowing the facts helps you choose the right products.

This article clears up myths about speed, cable quality, and power limits of USB-C. Understanding these points makes technology easier.

Speed Confusion

Not all USB-C cables support the same speed. The USB-C connector looks the same, but data transfer rates differ. Some cables only do USB 2.0 speeds, while others reach USB 3.2 or Thunderbolt speeds.

  1. USB 2.0 speed: up to 480 Mbps
  2. USB 3.2 Gen 1 speed: up to 5 Gbps
  3. USB 3.2 Gen 2 speed: up to 10 Gbps
  4. Thunderbolt 3/4 speed: up to 40 Gbps

Cable Quality

Many think all USB-C cables are equal in quality. This is false. Cheap cables may not follow safety standards and can cause damage. Good cables have proper shielding and certified chips.

Tips to choose quality USB-C cables:
  • Look for USB-IF certification label
  • Avoid very cheap cables from unknown brands
  • Check for proper length and thickness
  • Use cables that support your device’s power and speed needs

Power Limits

People think all USB-C cables deliver the same power. Power delivery depends on cable and charger ratings. Some cables support only 3A current, others support 5A. This affects charging speed.

Power RatingMaximum CurrentMax Power Delivered
Standard USB-C Cable3 Amps60 Watts
USB-C Cable with E-Marker5 Amps100 Watts
