Stuffcool Primus USB 4 Type-C to Type-C Cable with 240W Power and 40Gbps Data with 8K Video Transmission, 1.8M, Black

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 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.

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 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.

Not good in long term usage

One of the best usb type c cable i have even seen i haven't expected such a good quality cable from stuffcool brand i would like to give 10/5 stars cable length is good more than required charging speed i have tested upto 240w with my dji Mavic 4 charging hub and im currently using Samsung m7 monitor with my galaxy book 3 pro 360 a single cable connects all use connects display and charging at the same time in 4k it supports up to thunderbolt 4 connectivity its compatible with all devices the thickness of the cable is very good long lasting and durable for all conditions.

Great cable. Even better than HDMI. I was getting artifacts and delays with HDMI but with this, nothing at all. 4K, 60Hz No Problem at all along with 65W charging and USB hub.

It's a very great cable from Stuffcool. I was in doubt should I buy this or not as per the Negative Reviews of most the customers but that's not the case guys...Stuffcool makes genuine products, I'm one of the genuine users of their products and they work perfectly everytime, this cable is giving me Super fast Charging 2.0 to my S24 Ultra, Tab S9 Ultra and to other Galaxy devices too. It's also compatible with other smartphones too as my friends also charged with this cable (Oneplus, Xiomi, Vivo) and they're also getting the maximum charging speeds with compatible adapters. Durability is amazing of this cable it's 2 times thick than the original Samsung 5Amp Cable and Very Good Quality of Braiding fabric is used.
