USB Type-C Cable to USB: The Complete Guide
A USB Type-C cable to USB (also called a USB to type C USB cable, type-C to USB-A cable, or USB type-C to USB type-A cable) is the most widely-used cable in the world. It bridges the gap between modern USB-C devices and the billions of USB-A ports still in use on chargers, PCs, power banks, and car adapters.
When Do You Need a USB-C to USB-A Cable?
- Charging your phone with an older wall charger, power bank, or car charger that only has USB-A ports
- Connecting to a PC or laptop for data transfer when only USB-A ports are available
- Connecting accessories like keyboards, mice, game controllers, or external drives
- Android Auto / CarPlay connections in cars with USB-A-only head units
USB 2.0 vs USB 3.0: Which USB-C to USB-A Cable?
Not all USB to USB C cables are the same speed. USB 2.0 cables (thinner, cheaper) transfer data at 480 Mbps — fine for charging and syncing. USB 3.0 cables (often blue inside the USB-A connector) transfer at 5 Gbps —10× faster, essential for backing up photos or transferring large files. Both support the same fast charging speeds, so choose based on whether you need fast data transfer.
USB 2.0 Cable — From £3.99
- ✓ 480 Mbps data transfer
- ✓ Fast charging (up to 18W)
- ✓ Thinner and more flexible
- ✓ Perfect for charging only
USB 3.0 Cable — From £5.99
- ✓ 5 Gbps data (10× faster)
- ✓ Fast charging (up to 18W)
- ✓ Slightly thicker
- ✓ Best for data + charging
USB Cable Speed Comparison
Not all USB cables are created equal. Here's how every USB standard compares for speed and charging power.
| USB Spec | Max Speed | 1 GB Transfer | Max Charging | Best For |
|---|---|---|---|---|
| USB 2.0 | 480 Mbps | ~17 seconds | Up to 7.5W (1.5A) | Basic charging, syncing |
| USB 3.0 (USB 3.2 Gen 1) | 5 Gbps | ~1.6 seconds | Up to 15W (3A) | Fast data + charging |
| USB 3.1 (USB 3.2 Gen 2) | 10 Gbps | ~0.8 seconds | Up to 100W (PD) | External SSDs, docks |
| USB 3.2 Gen 2×2 | 20 Gbps | ~0.4 seconds | Up to 100W (PD) | Pro external storage |
| USB4 / Thunderbolt 3 | 40 Gbps | ~0.2 seconds | Up to 100W (PD) | Docks, eGPU, displays |
| Thunderbolt 4/5 | 40–80 Gbps | ~0.1 seconds | Up to 240W (EPR) | Pro creative workflows |
Transfer times are theoretical maximums. Real-world speeds depend on cable quality, device capability, and file sizes.
How to Choose the Right USB Cable
Four things to check before buying any USB cable — whether it's a USB to USB cable, USB-C to Lightning, or USB-C to HDMI.
1.Check the USB Specification
USB 2.0 for charging, USB 3.0+ for data transfer. Higher spec = faster speeds. Always check the cable packaging — not all USB-C cables are the same speed.
2.Verify Power Rating
For laptop charging, you need cables rated for 60W, 100W, or 240W. Phone charging cables need at least 3A (18W). Look for "E-marker" on 100W+ cables.
3.Choose Certified Cables
Look for USB-IF certification, Apple MFi (for Lightning), and CE/UKCA marks. Avoid unbranded cables that may lack safety protections.
4.Pick the Right Length
0.5–1m for portability, 1–2m for desk use, 2–3m for TV connections. Avoid 3m+ for high-speed data — signal degrades with length.
Don't Bottleneck Your Charger
A 65W GaN charger is only as fast as the cable you plug into it. Pair the right cable with the right charger for maximum speed.
