DIY 60W PD Power Bank With Arduino Real Time Battery Info Display

Recently, I was planning to get a 60W PD power bank for my laptop so that I don’t need to worry about my laptop running out of battery during lectures. However, all the 60W power bank on the market are bulk and expensive. That is why I decided to make my own.

While I was designing the power bank, I thought to myself, why can’t I make one with a real time battery display? That is why I started this project: A 60W PD power bank with real time battery information display!

To make this power bank, you will need some general parts that you might have already lying around in your home workshop.

10K resistors x 2
10K variable resistors x 2
5.1V zener diode x 2
Arduino nano
prototyping boards
3D printer
M2x5 screws x 4
soldering tools
buck converter (16.8V -> 5V)
ACS712 (5A)
power switch
However, you will also need to get some unique parts, which includes

UART HMI display (The one I am using is 2.2 inch)
4S (14.8v) Lithium Ion Battery (I am using 4 x Panasonic 3200mAH cells)
60W IP2716 based power boost & charging module”
