These high-quality cables offer efficient and fast charging and fast data transfer. The description mentions a data transfer rate of 5 Gbps and USB 3.0. I recently read that the new name for this speed is USB 3.1 Gen 1. In any case, only USB 3.1 Gen 2 is faster at 10 Gbps. The only thing I don't really like is that the cable is quite thick and a bit stiff, but I'm sure this also directly accounts for the high performance mentioned above. You also get Anker's outstanding customer service. Keep in mind that if you use such a cable to charge your phone along with a charger that has a USB output port, you won't be able to get the fastest charge that some phones with USB-C ports can accept . For faster charging, try duplicating the charger and cable that came with your phone.
