Parameter Comparison 40G USB4 Extension Cable 20G USB4 Extension Cable Passive TB4 Cable Active TB4 Cable 40Gbps USB4 Cable 20Gbps USB4 Cable Review: Good cable. - Great quality doesnt feel flimsy. Managed to get 25gbps with them. Review: This actually works, and works well - This is the only USB-C extension cable I've tried that actually works reliably and maintains a rock-steady connection (with power, 4k video and USB traffic going through) without freezing or cutting out intermittently. It looks and feels solid and very well built, although, I must admit, it’s a bit too stiff for my liking (perhaps a braided design would be more flexible). I wish there was a slightly longer variation. But all in all, this is an excellent extension cable. ## Features - 【Suitable USB-C / Thunderbolt Extension】Extend your USB-C devices with this USB C extension cable; simply connect it to the end of a standard USB-C cable or Thunderbolt cable to form an instant extension.
