This is a Nimaso USB Type C Thunderbolt 3 cable. I purchased it on Amazon and used it for about two years, but I'm selling it now because I no longer need it. Of course, I've confirmed that it works. I am currently visiting my parents' home, so I will ship it on or after the 4th. Please consider this before purchasing. https://amzn.asia/d/dmdaoRZ 40Gbps PD compatible 100W/5A ultra-fast charging Thunderbolt 3 cable, 5K/Ultra HD 60Hz video transmission, USB3.1 / 3.0 / 2.0 compatible Type-C cable, compatible with iPad Pro 11 / 12.9 (2021 M1 chip model/2020/2018) iMac 24inch MacBook Pro2019 Galaxy S21/S21+/S20+ Ultra Note20/20 Ultra Huawei Mate10/10Pro etc. (1m)
