How to charge arduino Uno? (Solved)

@PaulRB

@jim-p

5V pin on the UNO is an Output and NOT an Input

which I believe is incorrect,

This is a long-standing dispute, @jim-p has a special opinion on this matter:

Can a Nano Every be powered through the 5V pin?

Mod Edit, I split this because it's way off topic from the topic it came from. DO NOT connect 5V to the 5V pin, it is an OUTPUT, NOT an INPUT. Once you change Vin to 9V your 5V supply will now need to come from the nano every
