The cable itself might be rated for 100W when used with e-marked USB-C plugs.
But, there is no way you can expect any standard USB device to provide or consume 100W when there is a Type-A connector involved.
There are no official standards for negotiating that over Type-A, and likely no connectors that are rated to handle 100W over Type-A.
However, custom solutions with custom connectors may exist. For example a 100W SuperVooc charger can output 9.1A at 11V on Type-A connector which is 100W.
So your cable may really support 100W.
Your current charger and current phone might not.
Answer from Justme on Stack Exchangei've been searching but i can't seem to find such a cable. all the 100w cables transfer data at 480mb/s and all the cables that can transfer at 10gb/s are only 60w.

USB-PD only works on the type C connector; A-to-C cables do not and cannot support it.
There are other protocols, like Qualcomm Quickcharge, that work over a standard USB cable with any type of connectors, but they have to be supported separately by both the charger and the device being charged. USB-PD has basically replaced these in modern equipment.

What is the USB interface of this cable?
Is this cable only for charging?
Does this cable support video?
Like the cables of so many, mine is splitting in multiple places. I don't trust Amazon reviews thanks to product cloning and review farming, and since cable failure is such a common issue, I figured our community might have arrived at a few favorite options by now.
