Hello dear community members,
I want to use a smart display in my 3D printed project and make it USB rechargeable.

Display spesifics are like that:
Input: DC 5V-24V
Logic Voltage: 3.3V
Rated Power: 0.65W

At first I was thinking of using the J5019 circuit and the LPR755040 battery. ( Instead of the J5019 circuit, I can work with a separate Mt3608 or Sx1308, and a circuit like Tp4054 for charging)

However, I am not very good with electronics and wanted to consult pros before doing this.

My basic questions are like :
-How long it can work with the battery (+1 hour ok for me)
-What are my other circuit/battery options for this project.

Normally it needs to be powered by USB 5V, I thought if I make it battery powered, I can bring it with me to many places within wifi coverage.This way I won't have to constantly look at my phone, laptop or check the 3D printer.

Thank you for any advice..
