Frequently Asked Questions
Q: Is this USB4 adapter compatible with Thunderbolt 3 and Thunderbolt 4 cables?
A: Yes! The USB4 80Gbps USB-C female-to-female coupler is fully backward-compatible with Thunderbolt 3 and Thunderbolt 4 cables, as well as standard USB 3.2 and USB 2.0 Type-C cables. Performance will match the lower-spec cable or device in the chain.
Q: Can I use this adapter to charge my MacBook Pro at 240W?
A: Yes, provided you are using a 240W-rated USB-C PD charger and a USB-C cable that also supports 240W (USB PD 3.1 EPR). The adapter itself supports up to 240W Power Delivery pass-through, making it suitable for fast-charging compatible MacBook, iPad Pro, and high-powered laptops.
Q: Why does only one side of the adapter work for power?
A: This is a standard characteristic of USB-C female-to-female couplers — due to the way USB-C CC (Configuration Channel) pins work, only one end can be the power-receiving side at a time. If your connected device does not charge, simply flip the adapter and reconnect — the other orientation will engage the correct CC configuration.
Q: Does this adapter support 8K video output on the iPad Pro?
A: The adapter supports up to 8K@60Hz video pass-through; however, actual video resolution depends on the display capabilities of your connected device and monitor. iPad Pro currently supports up to 6K output via Thunderbolt — the adapter will pass through the maximum signal your device can generate.
