Know before you buy

Absolutely. This cable supports up to 100W Power Delivery, allowing you to charge your laptop at high speeds while simultaneously maintaining a 40Gb/s data connection.
At 0.8 meters (approximately 2.6 feet), this cable is designed for close-proximity connections, such as connecting a laptop to a docking station or an external drive on your desk. If you need to bridge a larger distance, you may need a longer cable.
Yes, it is fully capable of supporting high-resolution displays up to 8K, provided that both your computer and your monitor also support that resolution and the necessary Thunderbolt or USB 4 standards.
