Thunderbolt 3 cables - support Thunderbolt 3, USB 3.1 Gen 2, and USB 3.1 Gen 1 devices.
USB 3.1 Gen 2 cables - support USB 3.1 Gen 2 and USB 3.1 Gen 1 devices.
USB 3.1 Gen 1 cables - support USB 3.1 Gen 1 device.

A Thunderbolt 3 device requires a Thunderbolt 3 cable (as well as a port).

A USB 3.1 Gen 2 storage device requires a USB 3.1 Gen 2 cable (as well as a port), or a Thunderbolt 3 cable and port.
A USB 3.1 Gen 1 device can use either a Thunderbolt 3 cable or a USB 3.1 Gen 2 or Gen 1 cable. In certain cases, a USB-C device is also supported with a USB-C-to-USB-A adapter.

In other words, to benefit from all the attributes of Thunderbolt 3, you must have a Thunderbolt 3-compliant port, cable, and device.

Generally speaking, USB cables are classified into one of two different bandwidth groups: 1.1, which transfers data at a maximum rate of 1.5 Mbit per second, and 2.0, with a 480 Mbit per second data transfer rate. USB 2.0 is backward compatible with the lower data transmission requirements of 1.1, but the substitution can’t be reversed; 1.1 just can’t deliver the rate of data transfer that USB 2.0-rated devices need.

In addition to the bandwidth classifications listed above, USB devices can also be labeled in the following “speed” categories, which specify the amount of bandwidth they need to operate:

• Low Speed: The “low speed” rating indicates that a device requires minimal bandwidth (1.5 Mbit/s) to function, so it can be used in conjunction with either 1.1 or 2.0 USB cables. Joysticks, keyboards and computer mice are a few common examples of Low-Speed devices.

• Full Speed: Devices labeled “Full Speed” need a signal rate of 12 Mbit per second. Since this is such a common bandwidth requirement, all USB hubs on the market have been designed to support Full Speed. And even though the data transfer speed is higher, Full Speed — like Low Speed — transmits equally well via 1.1 or 2.0 USB cables.

• High Speed: “High speed” USB devices run at 480 Mbit per second and require a 2.0-rated USB cable.

• SuperSpeed: This category was developed with USB 3.0, with SuperSpeed+ within version 3.1.USB 3.0 allows for quicker connections, with USB 3.0 at 5 Gbit/s, 3.1 at 10 Gbit/s and UUSB 3.2 at 20 Gbit/s. USB-C is compatible with larger electronics and can support devices at a speed of 40 Gbit/s.

The PC/laptop USB interface and USB Cable may not be properly connected:
1) Please check whether the PC/laptop interface function is normal, you can use other wires to plug into the interface to test;
2) Please check whether the USB Cable and the interface are correctly connected;

1. Try another USB-C charging cable (if you have one).

2. Make sure the USB C port of your device is in good condition/works well.

3. Check all AC adaptor connections. See if the AC adaptor works.

4. Unplug everything, then plug in again, or try a different USB C port.


If all these are in a good shape, please contact us for a free replacement.

1. Please check that the protocols supported by the computer and the device are 2.0, 3.0, 3.2, USB4, TB3, TB4, etc., compare the theoretical speed with the actual speed, and pay attention to the speed of bits and bytes convert.

2. Please check CPU overload, it is recommended to quit unnecessary programs

3. Please check whether you copy and paste many files at one time, and the transfer rate of a single file is not so fast

4. Please conduct a comparison test, you can try to change the hard disk or change to another host interface for a comparison test

1. If it is a Samsung mobile phone, download and install the sidesync APP, and contact Samsung official support to solve the problem

The interfaces of Thunderbolt 3 and Type-C are basically the same, but Thunderbolt 3 will mark "3" or a lightning symbol on the connector and besides supporting USB 3.1 protocol version, Thunderbolt 3 can also transmit video signals.

If the computer USB interface and the computer driver are not installed properly, data recognition will be affected. Please check carefully whether the interface is loose.

MFi - made for iPhone/iPad (Apple Certified Lightning cable), You can log in to the official Phone MFi Licensed Accessories (mfi·Phone·com) and search our brand "CableCreation" to confirm.

Yes. The maximum data transfer speed is 480 Mbps.

The working temperature of a cable is 0-40°C. It can work in lower or higher temperatures (e.g.: -10°Cor 50°C), but it is not recommended because chargers and mobile phones may not work properly in such extreme temperatures.

Yes. Pair up with a Power Delivery charger to charge up to 87W.

A USB-C Power Delivery charger.

Our USB-A to Lightning cables support up to 5V/2.4A (12W) charging output.

1. Remember to unplug the cable from the adapter when not in use.

2. The Lightning connector is not waterproof. Please avoid storing your cable in high-humidity environments.

3. Use a little rubbing alcohol to wipe clean the Lightning connector surface occasionally and keep your charging port clean.

1. Laptops with Windows and macOS need to download the driver through the official website of the printer to connect.

2. iPads and Android tablets generally do not support connecting to a printer.

3. For wireless printers, please refer to the manual of the wireless printer for details.
