🎯 When to Pick USB-C to C
Opt for this cable if you own modern devices (2020+ laptops, flagship phones, tablets). Its superpowers include:
- Blazing-fast transfers: Move 4K videos or 10GB files in seconds (20-40Gbps).
- Laptop-ready charging: Power MacBook, Dell XPS, or other laptops with 100W+ USB PD 快充.
- All-in-one connectivity: Transmit data, charge, and output video to monitors—all with one cable.
Profi-Tipp: Look for USB 3.2/4 or Thunderbolt 4 certification for top performance.
📌 When to Choose USB-A to C
This cable is your bridge between old and new tech. Use it if:
- You have legacy chargers, power banks, or peripherals (printers, external HDDs) with USB-A ports.
- Speed isn’t critical (e.g., charging wireless earbuds or syncing photos from a phone).
- You need a budget-friendly backup cable for travel (works with most public charging stations).
Warnung: Even if your phone supports 65W fast charge, an USB-A to C cable will cap it at 18W—no exceptions.
🛠️ Pro Selection Tips
- Check device specs first: If your laptop requires 65W+ charging, USB-C to C is non-negotiable.
- Prioritize quality: Avoid cheap cables—look for braided sleeves and reinforced connectors to prevent fraying.
- Future-proof: Invest in USB-C to C for long-term use (USB-A is being phased out in new devices).

- Infographic: “Data Transfer Speed Comparison” (USB-C to C = 40Gbps vs USB-A to C = 5Gbps).
- Usage scenario: USB-C to C powering a laptop + monitor; USB-A to C charging a phone via an old charger.
Endgültiges Urteil
- USB-C auf C: The future-proof choice for speed and power.
- USB-A auf C: A temporary solution for legacy gear.
Most users benefit from owning both—keep a USB-C to C for daily use and USB-A to C as a backup. Choose based on your devices, not just price!
