For my Galaxy S21 Ultra 5G it was "super fast" charging when paired with the right connector. However. Like all cheap aftermarket cables it failed after 4 weeks and the second after a week. The speed was great. From 15% to 100% in 31 minutes. But if I have to buy new ones every month or two, then I just use Anker. It is 3 times more expensive but lasts 30 times longer. So if you want to use a "backup" cable in case you can't find the main cable, that's great. but not a good cable for everyday use.
