Review on Deegotech USB C to USB C Cable 10ft [2-Pack] - Fast Charging Charger Cord for Samsung Galaxy, MacBook, iPad Pro & More by Mark Jefferson

Bought to breathe new life into my Samsung Galaxy S9 which was charging slowly with an old cable. They worked fine for a while, but after a week of plugging and unplugging cables, the phone wasn't charging at all. I then bought two USB-C to USB-A cables from Revain Essentials and they work great. So yes it is an issue with the charging port on the phone and the design of these cables, I do not recommend them if you have a Samsung Gakaxy S9
