Parkside X20V Battery Powerbank USB Charger

Introduction: Parkside X20V Battery Powerbank USB Charger

This is a simple DIY power bank project which combines a cheap quick charge charging module with a Parkside 20V battery.

The module I used is here (2 ports, affiliate link):

The module is great and the quick charge is working like a charm on Samsung Galaxy 9 and 10.

I designed it using the fantastic Autodesk Tinkercad free online 3D modeling tool and I encourage you to try it by yourself, especially if you are a beginner. If you are looking for a more powerful 3D modeling tool, take a look at the Autodesk Fusion 360.

Supplies

Step 1: 3D Printing

Print your files from Thingiverse (top, middle, and bottom part):

When you finished printing, remove supports. There will be a little struggle with supports where the front corners of the board go, as they are just 2 mm high.

I used draft/rough settings, with support. The thing is divided into two big pieces (middle and bottom) in order to save filament - to prevent unnecessary support.

Step 2: Assembly

  1. Holes in printed parts are a little bit tight, you can (pre)screw the screws (screw-unscrew), it will be easier later
  2. Put wire terminals and place them in place, using hot glue.
  3. Solder another side of the wire to the charger board. Be careful with +- and before soldering put the module in the printed housing
  4. Screw the screws :)

Step 3: Test

To confirm that this thing is working, I took a few measurements. I used the simple Android app Ampere and compared 3 kinds of charging - using this charger, original Samsung wall charger, and PC USB port. Every time, I used the same USB cable (Samsung OOTB).

Also, I was able to fully charge my phone (0-100%) 2 times. To be honest, there is a little bit more juice in the Parkside battery, but I didn't want to push it.

If you're interested to take a look at the Parkside battery, here is a nice video. We can see that there are five 18650 cells inside.

Step 4: The End

If you decide to make this thing, please share your work :)

    This is a very good idea, I am considering making one as I am often in a position where I can't charge my phone, but have a drill. Mine I may add an LED to as well!

    Thanks :)
    Great idea to add LED to it. That's on my todo list, as I had few situations where this kind of reflector/torch would be helpful. I have few 94x50MM 15W COB LED chips in drawer waiting me to make use of them. If you want, I can let you know if/when I make something useable of it. And if you make it, please let me know.

    Hi, thanks :) and sorry for the late reply. You encouraged me to expand my post, so I added test section with little bit more info. There is stated on the battey that it has 40Wh (2000mA, 20V), so 1C should be 40W. And respect for your work :)
