[Important]: Since the USB 4 standard needs to be backward compatibility with USB 2.0, So every time you connect a USB C female to female adapter, there is half the probability that it won't work. Just flip the adapter over and try it again, and it's resolved. This is related to compatibility issues with USB-C protocol, not quality issues.
[Note]: If you try to connect 2 cables with a total length of more than 6 feet, it may cause the data transmission rate to decrease and the charging speed to slow down. So we recommend connecting shorter Type-C cables and making sure they are Type-C 4 compliant.
[Standard Interface]: This is a USB-C to USB-C adapter, which means that both ends are the same USB-C plug.
[SuperSpeed Charging & Data Transfer]: Supports power delivery up to 100W, providing faster charging speed for your device, with data transfer rate up to 40GBps. (Support Magsafe Charging)
[Wide Compatibility]: USB 4 female to female compatible with most Type-C devices, such as MacBook Pro, ChromeBook, Huawei P9, and other Type-C devices.
