Introduction: Parkside X20V Battery Powerbank USB Charger
This is simple DIY powerbank project which combines cheap quickcharge charging module with Parkside 20V battery.
Module I used is here (2 ports, affiliate link):
Module is great and quickcharge 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 little struggle with supports where front corners of the board goes, as they are just 2 mm high.
I used draft/rough settings, with supports. Thing is divided into two big pieces (middle and bottom) in order to save filament - to prevent unnecessary supports.
Step 2: Assembly
- Holes in printed parts are 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 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.
Step 4: The End
If you decide to make this thing, please share your work :)
