It's not a "deep dive" of the power adapter - it's part of a "deep dive" series of the laptop model, writing an article each about individual components.
Yeah, I wouldn't call any of these "Deep dives". Perhaps they're catered to the audience that might be reading their blog, but I doubt that audience differs much from the HN audience.
LTT had a video recently where he went to their production facilities and show how they’re actually making the laptops. Was pretty informative, more informative than the information we’re getting from framework themselves.
