DIY USB CHARGER

thingiverse

You were tired of your phone running out of battery, so you decided to create a rechargeable USB charger using some spare modules. The components involved in this project are as follows: 1 x Step-up Boost Module and 1 x Mini USB 1A Lithium Battery Charging Board. Additionally, you'll need a Rechargeable 18650 Lithium Battery for the charger. It took approximately 47 minutes to print everything out. Any comments or suggestions are highly appreciated. In case you're interested, there's also an .stl file for a charger that uses the same modules along with a solar panel, although the solar panel didn't provide enough power for the step-up boost module in tests. If you want to know more about the solar panel, it's the DIY Solar Panel Motor Drive Charging Board. Remember, apologies for any English mistakes! To assemble this project, solder the components together according to the image (connecting negative terminals), with the switch's common connected to the battery and each module. Before gluing everything in place, ensure it works properly by testing it first. If you need help, feel free to leave a comment, even though I'm not an expert!
