The world of USB technology has come a long way since its inception in the mid-1990s. From the early days of USB 1.0 to the latest USB4, the Universal Serial Bus has undergone significant transformations, offering faster speeds, improved performance, and increased versatility. With the introduction of USB-C, the landscape of USB technology has changed dramatically, leaving many users wondering which is faster: USB-A to C or USB-C to C.
Understanding USB Speeds
Before diving into the comparison, it’s essential to understand the different USB speeds available. The USB Implementers Forum (USB-IF) has defined several USB speeds over the years, including:
- USB 1.0: 1.5 Mbps (Low Speed) and 12 Mbps (Full Speed)
- USB 2.0: 480 Mbps (High Speed)
- USB 3.0: 5 Gbps (SuperSpeed)
- USB 3.1: 10 Gbps (SuperSpeed+)
- USB 3.2: 20 Gbps (SuperSpeed+)
- USB4: 40 Gbps (Thunderbolt 3)
USB-A to C: The Traditional Approach
USB-A to C cables use a traditional USB-A connector on one end and a USB-C connector on the other. These cables are commonly used to connect devices with USB-C ports to computers or other devices with USB-A ports. The speed of USB-A to C cables depends on the type of USB-A port used. If the USB-A port is USB 3.0 or later, the cable can support speeds up to 10 Gbps. However, if the USB-A port is USB 2.0, the cable will be limited to 480 Mbps.
Limitations of USB-A to C
While USB-A to C cables are widely available and offer a convenient way to connect devices, they have some limitations. The main limitation is the speed, which is determined by the type of USB-A port used. Additionally, USB-A to C cables may not support the latest USB-C features, such as Power Delivery (PD) and Alternate Mode (Alt Mode).
USB-C to C: The New Standard
USB-C to C cables use a USB-C connector on both ends, offering a faster and more versatile connection. These cables are designed to take advantage of the latest USB-C features, including USB4, Power Delivery, and Alternate Mode. USB-C to C cables can support speeds up to 40 Gbps, making them ideal for applications that require high-speed data transfer, such as video editing and data backup.

Comparison of USB-A to C and USB-C to C
In conclusion, USB-C to C cables offer faster speeds and more features than traditional USB-A to C cables. While USB-A to C cables are widely available and offer a convenient way to connect devices, they are limited by the type of USB-A port used. USB-C to C cables, on the other hand, offer speeds up to 40 Gbps and support the latest USB-C features, making them ideal for applications that require high-speed data transfer and video display.
| Feature | USB-A to C | USB-C to C |
|---|---|---|
| Speed | Up to 10 Gbps | Up to 40 Gbps |
| Power Delivery | Limited | Up to 100W |
| Alternate Mode | Limited | Supported |
In summary, if you need a fast and versatile connection, USB-C to C is the better choice. However, if you need to connect devices with USB-A ports, USB-A to C is still a viable option. Ultimately, the choice between USB-A to C and USB-C to C depends on your specific needs and requirements.
What is the main difference between USB-A to C and USB-C to C cables?
The main difference between USB-A to C and USB-C to C cables lies in their connectors and the technology used. USB-A to C cables have a traditional USB-A connector on one end and a newer USB-C connector on the other. This combination allows for the connection of newer devices with USB-C ports to older devices with USB-A ports. On the other hand, USB-C to C cables have USB-C connectors on both ends, making them suitable for connections between devices that both have USB-C ports.
In terms of functionality, both types of cables can be used for data transfer and power delivery. However, the speed and power delivery capabilities may vary depending on the specific cable and the devices being connected. It’s essential to choose a cable that meets the requirements of the devices being used to ensure optimal performance.
Which cable is faster, USB-A to C or USB-C to C?
The speed of a cable depends on the underlying technology and the capabilities of the devices being connected. In general, USB-C to C cables are faster than USB-A to C cables. This is because USB-C to C cables can support the latest USB standards, such as USB 3.2 Gen 2 and USB4, which offer faster speeds of up to 20 Gbps and 40 Gbps, respectively. On the other hand, USB-A to C cables are typically limited to USB 3.2 Gen 1 speeds of up to 5 Gbps.
However, it’s essential to note that the actual speed of a cable also depends on the devices being connected. If one device only supports USB 2.0, for example, the cable will only operate at USB 2.0 speeds, regardless of its capabilities. Therefore, it’s crucial to check the specifications of the devices being used to determine the maximum speed that can be achieved.
Can I use a USB-A to C cable for power delivery?
Yes, USB-A to C cables can be used for power delivery, but the power delivery capabilities may be limited. The amount of power that can be delivered over a USB-A to C cable depends on the specific cable and the devices being connected. Some USB-A to C cables may only support up to 2.5W of power delivery, while others may support up to 100W.
It’s essential to check the specifications of the cable and the devices being used to determine the maximum power delivery capabilities. If you need to charge a device that requires more power, such as a laptop, you may need to use a USB-C to C cable that supports higher power delivery.
Are USB-C to C cables more expensive than USB-A to C cables?
In general, USB-C to C cables are more expensive than USB-A to C cables. This is because USB-C to C cables require more advanced technology and materials to support the latest USB standards and higher power delivery capabilities. Additionally, USB-C to C cables may be more difficult to manufacture, which can drive up costs.
However, the price difference between USB-A to C and USB-C to C cables can vary depending on the specific cables and manufacturers. Some USB-C to C cables may be priced similarly to USB-A to C cables, while others may be significantly more expensive. It’s essential to shop around and compare prices to find the best value for your needs.
Can I use a USB-A to C cable with a USB-C hub?
Yes, you can use a USB-A to C cable with a USB-C hub, but the functionality may be limited. A USB-A to C cable can be used to connect a device with a USB-A port to a USB-C hub, but the hub may not be able to take full advantage of the cable’s capabilities.
For example, if the USB-A to C cable supports USB 3.2 Gen 2 speeds, but the hub only supports USB 3.2 Gen 1 speeds, the cable will only operate at USB 3.2 Gen 1 speeds. Additionally, the hub may not be able to deliver power over the USB-A to C cable, or may only be able to deliver limited power.
Are USB-C to C cables more durable than USB-A to C cables?
In general, USB-C to C cables are more durable than USB-A to C cables. This is because USB-C to C cables have a more robust design and are built with higher-quality materials to support the latest USB standards and higher power delivery capabilities.
USB-C to C cables also have a reversible design, which means that they can be inserted either way into a USB-C port. This can help reduce wear and tear on the cable and the port, as users don’t have to worry about inserting the cable the correct way.
However, the durability of a cable also depends on the manufacturer and the specific materials used. Some USB-A to C cables may be built with high-quality materials and be just as durable as USB-C to C cables. It’s essential to read reviews and do research before purchasing a cable to ensure that it meets your needs.
