These cables work as advertised for the first few weeks. I use one in my Google Pixel 3 box (Google's original cable broke) and get full and fast USB-C power delivery. The other one I use in my car with a 3rd party USB-C PD car charger and it also charges from the PD. I still have one in reserve. I've been using Volutz cables for a while but couldn't find any USB-C to USB-C cables from them so I tried these instead. They feel just as strong and durable, just how I've come to love Volutz cables. I assume these cables will hold up.
