USB-C can feel confusing because the same connector can support different charging speeds, video output and data transfer levels. The key is to match the cable and charger to what your device actually needs.
Watts tell you the charging ceiling
A phone may fast charge at lower wattage than a laptop. A 100W USB-C cable gives you room for higher-power setups, but the final speed also depends on your charger and device.
The cable matters
Thin or unknown cables can limit charging speed. Use a cable rated for the wattage you expect, especially when charging tablets, power banks or laptops.
Keep one reliable cable in every setup
One cable at your desk, one in your bag and one near your travel adapter is usually enough. This keeps charging simple and avoids last-minute cable hunting.
