Feature(may vary by option.)

●⭕[Exquisite Workmanship] Aluminum alloy shell by micro-arc oxidation process makes the shell surface harder and more wearable. Strict quality inspection standards, fine appearance details, refuse to be shoddy.
●⭕[Professional Knowledge 1] Since the USB 3.2 3.1 standard needs to be backward compatible with USB2.0, every time this kind of USB Type-C female to female adapter is connected, there is a 50% chance that it will be non-functional. Just unplug, reverse one side, insert again, solve. This is an industry standard issue, not a quality issue.
●⭕[Professional Knowledge 2] If the total length of the 2 cables you are trying to connect exceeds 2M, and the quality of the cables is not very good, it may cause the data transmission rate to decrease and the charging speed to slow down. This is an unchangeable physical principle. The adapter is a non-destructive connection.
●⭕[Knowledge That Only Experts Know] The contact shrapnel is made of high-elastic, high-conductivity copper. After 10000 times plug & unplug test, the shrapnel contact resistance is still less than 15mΩ, this is very important for adapter.
●⭕[Compatibility] Widely work with most Type C devices. For MacBook Pro; Surface Book 2; Samsung Galaxy S21 S20,S10, Note20 10; LG G7 V20; Google Pixel, ChromeBook, etc.

Description

⭕[Learn While Buying] Confused by the name of USB 3.2 3.1 3.0 Gen 1 Gen 2? Heres the right answer:

USB 3.2 Gen 1=USB 3.1 Gen 1=USB 3.0 (5Gbps)
USB 3.2 Gen 2=USB 3.1 Gen 2 (10Gbps)
USB 3.2 Gen 2*2=USB 3.1 Gen 2*2 (20Gbps)

⭕[Functions] Extend Type-C cable, joins 2 USB C male cables, support charging & data transmission, compaitble with TB3 ports.

⭕[Parameters] The maximum voltage is 20v, the maximum current is 5A, the maximum power can reach 100W, and the maximum transmission rate is 10Gbps. (10Gbps is the theoretical maximum transmission speed. According to the bucket theory, the actual speed depends on the device with the lowest speed).

⭕[4K Resolution] The USB Type c expansion coupler can transmit video and audio signals, and expand to a variety of audio and video output interfaces: HDMI, DVI, and VGA interfaces, which can achieve 4K resolution expansion.

⭕[Compatibility] Widely work with most Type C devices. For MacBook Pro; Surface Book 2; Samsung Galaxy S21 S20,S10, Note20 10; LG G7 V20; Google Pixel, ChromeBook, etc.
