USB4 for Thunderbolt 4 Cable 1.6FT, Support 8K@60Hz, 4K@144Hz 40Gbps/240W PD Charging for iPhone 17, Mac mini M4 / M4 Pro, MacBook Pro, Docking, eGPU, SSD, Surface Pro

Replaced Review -- I bought this item to connect my AMD MiniPC to my eGPU, and was beyond mad when it couldn't output successfully. * I tested it for providing power and it happily provided over 100w as it advertised. * I tested it for video output and it handled 1440p and 1080p happily (I don't have a 4K display). * I tested and it supported data transfers. But because it didn't do the one esoteric thing that I wanted, for my one ideal setup, I gave a 1-star review and spent about 8 paragraphs trash-talking the vendor. I was surprised when they next refunded me and messaged *me* to apologize. I told them that while the $5 back was nice, I wanted a working cable, and in response they sent me a replacement immediately. That cable arrived tonight, and when I tested it, I found out that it COULD support my eGPU with an Intel computer I have, but not with my AMD MiniPC. Now I'm wondering if the USB 4 implementation on this little machine is wonky and if it is just picky with cables. If the problem was on my end. So, first, I rarely have been in a position to say this but I feel like I owe the vendor an apology -- their cable works for Thunderbolt 4 PCIe data transfers, even if it didn't work for my favorite little machine's USB 4 implementation. I'm leaving some of my analysis, below. Long-winded analysis: I tested this cable for WAY too much of my day, because I need a backup cable for my eGPU to connect to my MiniPC. *Many* Cables can make use of the *many* alternate profile features of USB C specifications. * USB Alt-DP allows video over C-to-C cables for USB 3 and USB 4 ports, if all vendors incorporated the features correctly. * USB PD allows high-speed charging, with specifications like PD 3.1 support 120w or 240w charging, at 5A. * USB 4 offers the same intense speeds of throughput as USB 3's latest version, but with greater reliability, with a roadmap to exceed those speeds like TB 5 already has. * USB 4 devices can include most of the Thunderbolt 3/4 features, including piping PCIe data over the interface, which is why there's been an explosion of cheap eGPU solutions in recent years. This cable can support *some* of these features, but it isn't fully capable of Thunderbolt over USB 4 integrations with my cheapo AMD MiniPC. It DID support the eGPU when paired with another, different PC. This cable would display 1080p mirror of my Samsung Android phone's screen just fine. The cable would also charge an accessory. No matter how many times I flipped the cable ends to test reinserting, or rebooting either and both devices, at the end of over an hour, I could consistently my eGPU dock with my AMD MiniPC when I used any of my own previous thunderbolt cables, but could not with this thing, try as I might. I know that it works with an Intel NUC 8, and an Intel NUC 12, and that it does everything else they advertise. It may be an issue with my specific AMD MiniPC, or with the specific manufactured line my PC comes from, but they DO otherwise support eGPU's. Because it's Amazon and they are generous with returns, and because the price tag is the cheapest I've seen for TB capable cabling, and because the company **BACKS THEIR BRAND** by supporting their product and being proactive with their customers, I'll say that I upgraded my opinion to 5 full stars, and that I'll be using the cable they sent me for literally every other purpose.

Judging by appearance and ease of use, these cables are very good. The system for which they are a part seems to be as fast as I would expect from Thunderbolt 4.

exactly what I needed to get my thunderbolt drives to read at full speed pulling over 2100Mb read and over 700MB Write speeds on most SSD’s

I have only evaluated the charging speed with this cable and the 240W rating meant I could charge my iPad more rapidly than I was ever able to do so previously! I am looking forward to testing out the data transfer capabilities.

I use this for a egpu enclosure that I run AI inference on and cannot find the proper tb4 specs on almost any cable on the market. I previously purchased four others from Amazon including one from Belkin and one from monster. All of them claim to be thunderbolt for but did not work properly. The length was perfect for the two ft. That I needed from the controlling unit to the egpu enclosure and the durability is by far the best of any cable I've ever experienced with a braided body and rubber grommet ends that will most likely never fail. I was extremely impressed with the 40 GB per second connection speed!

I do wish the cord was more flexible, but it's definitely not a deal breaker. It works great! My cheap boost phone (celero 5g+) will only charge up to 15 watts and with this cord, it does charge as fast as my phone will allow,15 watts (plugged into my power station that tells the wattage being used). The only other issue is the "casing" I guess you'd call it, around the part that plugs in. It is too thick for a couple of my electronics and does not allow it to be pushed in far enough to work. It does seem like it will last, so I'd say it is a good enough value to buy, I believe it should fit most items, if not you can return it.

excelent cable

not a thunderbolt cable. I tried plug this into my laptop and dockstation, but all functionalities are limited as if the cable is not certified thunderbolt. the external display port on dockstation does not work. I tried with my other thunderbolt cable and it works just fine
