There are a ton of questions posted similar to this but not quite this from what I had found, and I'm looking to understand this a bit more.
I have a Raspberry Pi 3 as well as the official 7" display. I can power it with no issues using a 5V/2.5A plug in power supply. I'm looking to be able to power it on the go.
I have an Anker Power Core 20100 Switch Edition (https://www.anker.com/products/variant/powercore-20100-nintendo-switch-edition/A1275S11). It has 2 power output ports:
A USB-C output rated at: PD Output: 5V=3A / 9V=2.6A / 15V=1.6A A standard USB port output rated at: Standard Output: 5V=2A
I expect that 5V/2A might not be enough to power the pi + display.
So really, two questions: 1) Is there harm in me attempting to use the 5V/2A and see if that's enough current to power my scenario, or would this cause issues? 2) If I get a USB-C to USB standard port adapter, then use a USB cable to plug from there into the Pi (something like this: https://www.amazon.com/Anker-Adapter-Converts-Resistor-MacBook/dp/B01AHKYIRS), would that affect the power output and drop the max current?
