All USB-C cables can accept at least 60W. Certified USB-C 3.1 Gen2 should also be able to accommodate 100W.
Anker’s Thunderbolt cable is here to accommodate 40Gb/s data and monitors while maintaining compatibility with USB 3.1 Gen2. It’s a great all-in-one cable thanks to its maximum allowable passive cable length of 0.5m. However, the need for 40Gb/s data for an average consumer is just not there yet.
Unless there’s a current need for it (40Gb/s data or monitor), I still think the PowerLine II USB-C to USB-C 3.1 Gen2 is still the better cable to get. In addition to USB-C 3.1, it can do 20Gb/s data for Thunderbolt3 and future USB 3.2 devices with 1m length cables, coupled with lifetime warranty at a better lower price.
