This Type-C to Type-C cable is excellent in terms of build quality. It's sturdy, tough, and has a good thickness that gives it a premium feel. The 1.8-meter length is perfect—long enough for convenient use without being too bulky. It supports my 100W charger flawlessly, making it ideal for fast charging my phone. Data transfer speeds are also impressive. Overall, a reliable and well-built cable that delivers on both performance and durability. Highly recommended

I got this 1m highspeed/high data c to c cable and tried transferring some large amounts of data between two devices and it’s insanely fast. 🌟 .. This seems strong and durable at this price range. Easily attached to almost all of my latest devices my macbook, iPad and iPhone Loved it………🤩

Works like a charm...i don't write reviews for products that are good, but decided for this one...I can connect my macbook and ipad and also the dell laptop to my monitor through this cable, and it also charges my laptops when connected to the monitor...since the macbook air doesn't have a hdmi port, i was looking for type c to hdmi cables, but realized my msi DP 271 Monitor do support type c input, so i searched and stumbled upon this one...found some reviews reporting some disconnection issues, but my cable is working fine till now...also it comes with 6 months warranty...i can use this cable both for charging, data transfer and display output...cable quality is also very good...

I was initially worried about the quality and utility of this Stuffcool Primus USB-C cable, but I am super happy with my purchase. You can confidently go for it! For those who want a detailed review, keep reading. I wanted a single cable that could replace both my Mac power cable and the HDMI cable for my Samsung M7 4K monitor. This cable does exactly that. I can easily extend my Mac’s screen to the 4K monitor while simultaneously charging the MacBook. Despite some concerns from other reviews, I can confirm that this cable supports DisplayPort Alt Mode and delivers excellent charging speeds along with solid build quality. Special kudos to the Stuffcool support team who answered all my doubts promptly through their support channel. Technical Details: -> When connected to my 140W Mac power adapter, this cable provides excellent charging speed, taking my MacBook from 0 to 100% in the same time as the original Apple cable. -> My Mac shows that in DP Alt Mode, the cable delivers 65W of power for charging. -> Video output via USB-C supports DisplayPort 1.4 Alt Mode with smooth 4K resolution at 60Hz. -> USB data connection on the USB-C port runs at USB 2.0 speeds (480 Mbps max). Between my mac and monitor, which is limited by my monitor’s maximum supported speed. Overall, this cable is a high-quality, versatile solution for charging and video output, making it a great buy for Mac users needing a single cable for power and display.

Not bad it is good product gold plated type c tick and sturdy nylon black cable transfer speeds are great, usable for usb 4.0 purpose also works fine as a diplay cable But after using it for 3-4 months now it has become so inconsistent keeps connecting and disconnecting when charging connection is very finicky can't use it properly for data transfer either ssd keeps getiing connected nad dosconnecting on this, i have another much older and cheaper usb 4 cable which is so much better, i thought this one from brand would be better but it isn't waste of money in long term

Such good quality cable so useful and connects easily charges at great speed

I bought this cable to bridge a high-speed link between devices, and the performance is exceptional for a 1.8-meter cable. The Test Setup: Source: MacBook M1 Destination: MacBook M2 (Running iperf3 server) Connection: Direct Thunderbolt/USB4 bridge via the Stuffcool Primus. Performance Results: Running a 10-second iperf3 stress test, I achieved a rock-solid 37.6 Gbits/sec average. Transfer: 43.8 GBytes Bitrate: Consistent 37.6 - 37.7 Gbps throughout the entire duration. Note on the "Missing" 2.4 Gbps: For those wondering why it isn't hitting the "full" 40 Gbps: this is actually proof the cable is working perfectly. macOS reserves roughly 2.4 Gbps for DisplayPort/video overhead and system PCIe management. Seeing 37.6 Gbps in iperf3 means you are hitting the absolute ceiling of usable data bandwidth on a Mac-to-Mac USB4/Thunderbolt bridge. Pros: Reliability: No drops or packet loss during high-bandwidth transfers. Length: 1.8M is generous; usually, you have to pay a massive premium or settle for 0.8M to get these speeds. Build: The braiding is high quality and the connectors feel industrial-grade. If you are a developer, sysadmin, or video editor looking for a reliable 40Gbps/240W cable that actually lives up to the spec sheet in India, this is the one to get. Power Delivery: I tested this with my Apple 96W adapter and it registered 94W of power delivery consistently. I don't have a 240W charger to test the upper limit yet, but for MacBooks, it handles the power handshake perfectly.

After 1 week: I tried a replacement to check if the problem is with first delivered cable. I was not sure so did some chatGPT and got to know that USB-C display cabled should tell if the "DP Alt Mode" is available or not as most of the monitors (mine is LG) with USB-C port use that. I ordered another cable with DP Alt Mode as Amazon Basics cable is discontinued which I was using all these years and that cable is working fine. Also now return is enabled via Amazon so that is a plus so changing my rating. This cable might work with thunderbolt monitors but not with USB-C port monitors. Seller should give disclaimer of it. First Reveiw: My MacBooks are working fine with 5 years old amazon basic USB3 cable but NOT WORKING WITH THIS CABLE. I wanted to use it with my Macbook M4Pro which has thunderbolt 5 support, backward compatible off course . I can’t even return this directly via Amazon but need to courier them to get my money back. Complete TIME WASTE which I thought I was saving with Amazon fast delivery.
