These are the only 100w of magnetic cables available in the country. They are worth the price for their purpose, but the quality is not great. I've ordered about 6 from Nestelle and a few have either been broken upon arrival or some of the tips randomly don't work or fail. If you get a fault cord DO NOT USE IT. I'm had a rotating one that had a flickering led on it. I used it on my OG gram 17 by accident (I had two of the same colour) and it fried the computer. Dead. That said I've been using others for about 8 months now and charge all my high end mac products - 11 pro max, iPad 11 pro and MacBook Pro without a hitch. They are fantastic. Changed the way I do things. I ended up getting cheaper ones for my older usb-c accessories like ps4 controllers. This is the way. Wish Nestelle would make better quality, but worth it in the meantime.
