I had a Microsoft surface book 2. The provided charger could not provide enough power to the device when it was under heavy load and there was no higher charger option either. That shit should be illegal. And if the battery for the base/GPU died? You can't use the computer w the gpu even with a charger attached. The device itself could have been a dream and something i could have seen Apple doing : a touchscreen monitor that was also a computer and could be detached from the keyboard/gpu.
