I can’t find a power spec anywhere for the touchscreen. Even the documentation that came with the screen makes no mention of it. The only thing I can find is the recommendation at raspberrypi.org of using a 2A power supply to power both the pi and the screen.
Edit: I just found it buried in the text rather than listed as a spec.
