This simple DIY power bank project combines a cheap quick charging module with a popular Parkside X20V battery to make a portable USB charger.
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 looking for a more powerful 3D modeling tool, take a look at the Autodesk Fusion 360.
Needed parts and materials
- Printed parts (Thingiverse)
- Charging module (AliExpress, eBay)
- 4x M3 screw (20mm length) (AliExpress, eBay)
- 2x wire terminals
- Wires
- 3D printer filament
- 3D printer
The module is great and the quick charge is working like a charm on Samsung Galaxy 9 and 10.
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 supports. 3D printed enclosure of Parkside USB charger is divided into two big pieces (middle and bottom) to save filament – to prevent unnecessary supports.
Step 2: Assembly of Parkside USB Charger
- Holes in printed parts are a little bit tight, you can (pre)screw the screws (screw-unscrew), it will be easier later
- Put wire terminals and place them in place, using hot glue.
- Solder the other side of the wire to the charger board. Be careful with +- and before soldering put the module in the printed housing
- Screw the screws 🙂
Step 3: Test
To confirm that the this thing is working, I took a few measurements. I used simple Andrid 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 little bit more juice in Parkside battery, but I didn’t want to push it.
If you’re interested to take a look into the Parside battery, here is nice video. We can see that there is five 18650 cells inside.
