Based on the USB-C implementation issue in Pi 4 rev. 1, I'm looking for recommendations on a non e-marked USB-C cable to use for power. Having dug through my own cable stash, I've found a couple of cables that meet this requirement, but nothing brand named that I can identify and purchase online.
The context for this request is a networking course I will be teaching beginning in January. Due to infrastructure constraints, it's not feasible to have all students relying on AC power, e.g., the RPi approved power supply. Based on past troubleshooting experience, I prefer to provide a list of approved power banks. I'm already anticipating that the USB-C factor is going to cause problems in the next iteration due to the incompatibility of e-marked cables.
In lieu of the Raspberry Pi Foundation offering a standalone USB-C cable option that is verified compatible with rev. 1, I'm hoping that StackExchange contributors can help me find a good online source!
