If you plug a USB-C device into a Thunderbolt port, it will likely work as expected, but with some limitations. The device will operate at USB-C speeds, up to 10 Gbps, rather than the faster Thunderbolt speeds. This is because the Thunderbolt controller in the host computer will negotiate with the USB-C device to determine the maximum speed and capabilities. In most cases, the device will function as if it were connected to a standard USB-C port.
Thunderbolt Device in a USB-C Port
The opposite scenario, plugging a Thunderbolt device into a USB-C port, is a different story. The device may not work at all, or it may function at reduced speeds, depending on the capabilities of the USB-C port. This is because Thunderbolt devices require a Thunderbolt controller and specific software to function, which may not be present in a standard USB-C port.
Key Considerations and Potential Issues
When plugging a USB-C device into a Thunderbolt port, or vice versa, there are several key considerations and potential issues to be aware of:
Incompatible Devices
Some devices may not be compatible with the host computer or the Thunderbolt port, even if they have a USB-C connector. This can be due to various reasons, including firmware or software limitations.
Speed Limitations
As mentioned earlier, plugging a USB-C device into a Thunderbolt port may limit the speeds to USB-C levels, rather than the faster Thunderbolt speeds.
Power Delivery
USB-C and Thunderbolt ports can deliver different levels of power. USB-C ports typically deliver up to 100W, while Thunderbolt ports can deliver up to 240W. If a device requires more power than the host computer can deliver, it may not function properly.
Thunderbolt Version
The version of Thunderbolt can also impact compatibility and performance. Thunderbolt 3, for example, offers faster speeds and higher power delivery than Thunderbolt 2.

What is the difference between USB-C and Thunderbolt?
USB-C (Universal Serial Bus Type-C) and Thunderbolt 3 are both connector types used for computer peripherals, but they have different capabilities and purposes. USB-C is a USB connector type designed to be reversible and faster than traditional USB connectors, with speeds of up to 10 Gbps. Thunderbolt 3, on the other hand, is a faster interface that uses the same physical connector type as USB-C but has speeds of up to 40 Gbps.
Thunderbolt 3 is also capable of supporting higher-resolution displays, faster data transfer, and can even supply power up to 100W, making it a more powerful interface. However, not all USB-C ports support Thunderbolt 3 speeds, so it’s essential to check your device’s specifications to see what it supports.
Will any USB-C device work with a Thunderbolt 3 port?
Any USB-C device will physically fit into a Thunderbolt 3 port, as they use the same connector type. However, the device may not take full advantage of the Thunderbolt 3 speeds. For example, a USB-C drive that only supports USB 3.2 speeds will only transfer data at up to 10 Gbps, even if it’s connected to a Thunderbolt 3 port that supports faster speeds.
However, some devices, like Thunderbolt 3 hard drives or docks, are designed to take full advantage of the Thunderbolt 3 speeds. These devices can supply power, send video signals, and transfer data at much faster speeds than standard USB-C devices. To get the most out of your Thunderbolt 3 port, it’s best to use devices that specifically support Thunderbolt 3 speeds.
Can I plug a Thunderbolt 3 device into a USB-C port that doesn’t support Thunderbolt 3?
If you plug a Thunderbolt 3 device into a USB-C port that doesn’t support Thunderbolt 3, the device will still work, but it will only use the USB-C speeds and capabilities. For example, if a Thunderbolt 3 hard drive is connected to a USB-C port that only supports USB 3.2 speeds, the drive will only transfer data at up to 10 Gbps, not the faster Thunderbolt 3 speeds.
This is because the Thunderbolt 3 device can fall back to using the USB-C protocol if the port doesn’t support Thunderbolt 3. This means you won’t get the full benefit of the Thunderbolt 3 speeds, but the device will still work, albeit at slower speeds.
Will a Thunderbolt 3 port charge my USB-C device?
Yes, a Thunderbolt 3 port will charge your USB-C device. In fact, Thunderbolt 3 ports can supply up to 100W of power, which is often more than a standard USB-C port. This means you can charge your laptop or other devices faster and more efficiently using a Thunderbolt 3 port.
However, it’s worth noting that some USB-C devices may only support USB Power Delivery (PD) up to 18W, even if the Thunderbolt 3 port can supply more power. In this case, the device will only charge at the slower rate.
Can I connect a display to a Thunderbolt 3 port using a USB-C cable?
If your Thunderbolt 3 port supports DisplayPort Alternate Mode (DP Alt Mode), you can connect a display to a Thunderbolt 3 port using a USB-C cable. DP Alt Mode allows a Thunderbolt 3 port to carry a DisplayPort signal, which can drive high-resolution displays.
However, not all Thunderbolt 3 ports support DP Alt Mode, so you’ll need to check your device’s specifications to see if this is an option. Additionally, you’ll need a USB-C cable that supports DP Alt Mode and a display that uses a USB-C port with DisplayPort capabilities.
Will a Thunderbolt 3 device work with a USB-C hub or adapter?
Thunderbolt 3 devices are designed to work with Thunderbolt 3 ports directly, so using a USB-C hub or adapter may affect the speeds and capabilities. Some USB-C hubs or adapters may support Thunderbolt 3 speeds, but others may not, so it’s essential to check the specifications before buying.
If you need to use a Thunderbolt 3 device with a USB-C hub or adapter, look for a product that specifically supports Thunderbolt 3 speeds and has been certified by Intel. This will ensure that you get the best possible performance and compatibility.
Can I mix Thunderbolt 3 and USB-C devices on the same daisy chain?
Yes, you can mix Thunderbolt 3 and USB-C devices on the same daisy chain. Thunderbolt 3 allows for up to six devices to be connected in a daisy chain, and this can include a mix of Thunderbolt 3 and USB-C devices.
However, keep in mind that the speed and capabilities of the entire chain will be limited by the slowest device. If you have a USB-C device in the chain that only supports USB 3.2 speeds, for example, the entire chain will only transfer data at up to 10 Gbps, even if there are Thunderbolt 3 devices on the chain.
