Best USB-C Cables: What Actually Matters
A cheap cable can bottleneck a great charger — or fail after a month. USB-C cables look identical but perform very differently. Here's what to check so you buy once and buy right.
1. Power rating (wattage)
Cables are rated for how much power they can safely carry. A cable rated for only 15W will charge your laptop slowly no matter how good your charger is.
- 60W (20V/3A) — great for phones, tablets and many laptops.
- 100W (20V/5A) — needed for high-power laptops; look for an "e-marker" chip.
2. Data speed
If you only charge, any cable works. If you transfer files or connect a display, check the data spec — USB 2.0 (480 Mbps) is fine for charging, while USB 3.x is much faster for data.
3. Build quality
- Braided nylon jackets resist fraying and last far longer than plain PVC.
- Aluminium connector housings handle repeated plugging without loosening.
- Reinforced strain relief where the cable meets the connector prevents the most common failure point.
4. Length
Shorter cables (1–1.2m) charge slightly more efficiently and are tidier on a desk; longer cables (2m) are better for the couch or bed. Have one of each.
Our pick
The C20-03 USB-C to USB-C 60W cable hits the sweet spot: braided, aluminium connectors, 60W fast charge and a handy 1.2m length.
