Understanding USB-C cable types is more important than ever in 2026. With laptops supporting 140W charging and USB-C Power Delivery 3.1 enabling up to 240W, choosing the wrong cable can limit performance — or worse, create compatibility issues.
In this complete guide, we explain the differences between 60W, 100W, and 240W USB-C cables, how to choose the right one, and which type is best for your device.
Why USB-C Cable Types Matter in 2026
Not all USB-C cables are built the same. While they may look identical, different USB-C cable types support different voltage and power levels.
- 60W (Standard charging)
- 100W (High-power laptops)
- 240W (Extended Power Range – PD 3.1)
