There's nothing reasonable about these assumptions.
There's no way the VisionPro gets even close to 100W. Why? Because heat dissipation. The vast majority of power drawn by semiconductors is dissipated as heat and, in a device that's strapped to someone's face, there's simply no way to dissipate hundreds of watts.
Also, knowing the battery pack size and battery life, it's easy to guesstimate the power consumption.
“The Apple Vision Pro provides approximately 2 hours of battery life. Based on its size, the internal battery capacity is estimated to be within 20,000mAh (74Wh), resulting in an overall power consumption of around 30W.”
Even if we assume the double of that 30W, it's well within USB-C standards.
That's irrelevant here because what they're describing is happening in every market, not just their niche.
