Having to purchase overpriced box on top of already costly GPU and wiring all up including one power adapter each for laptop and eGPU is already a bad experience.
At least in theory (going off marketing materials¹ for one such device, though I personally lack first-hand experience here, and said device doesn't advertise itself as Mac-compatible), the eGPU should function as the power source for the laptop, so you'd only need one power adapter (for the eGPU).
Really, this experience actually sounds pretty pleasant.
