Review on USB Type-C to USB Type-C 3.1 Gen1 Adapter Charger Cable - 6 Feet (1.8 Meters) - Amazon Basics - Black by Mark Taylor

I bought a new USB-C charger (Anker 100W/88W) and got one as a second charger for my Macbook Pro. I spent the better part of a week troubleshooting my MBP that accidentally shut down while it was online. I suspected I had a bad battery, but then found that the laptop only registered the charger at a total output of 60W, which wasn't enough when the laptop was heavily CPU-loaded. I thought I bought the wrong Anchor block. The specs seemed right, so as a final test, I took a USB-C cable from an original Apple charger and plugged it into the Anker power bank. Of course, I immediately signed up for 88 watts. I don't know why this particular cable doesn't allow my MBP to charge over 60W, but unfortunately the cable doesn't work with my use case. Too bad - actually a good cable. It's thick, has great insulation, and feels like it's built to last. I don't have enough USB-C context to understand what the limitation is in this scenario.
