This is a small charger I made for charging flashlights while camping. I wanted to use supercapacitors instead of a battery, which was really fun and simple as the charging circuit was pretty idiot proof.
Features:
The 3000f capacitor space (~3200mAh) to charge stuff
A solar panel to charge the capacitor bank
USB-C out (5V 1A)
Loops on the top side to attach it to your gear or hang it somewhere
Lips on 3 sides of the back to facilitate propping it up with sticks to get a good angle to the sun.
List of Supplies:
1 5V or 6V solar panel, 60mm x 110mm: https://www.amazon.com/dp/B0B8YHP7NR
1 USB-C out board: https://www.amazon.com/dp/B0F3WVBGCP
1 5v boost board: https://www.amazon.com/dp/B0BL7BRDYM
2 1N5817 Schottky Diodes: https://www.amazon.com/dp/B0FC2CTR7F
2 3000F Graphene Super Capacitors: https://www.alibaba.com/product-detail/Versatile-super-capacitor-2-7v-3000f_1600996044052.html
Assembly Instructions:
Ok, wiring this up is a bit of a trip.
Let's start with the Super Capacitor bank. Solder the + of one capacitor to the - of the other. Yay, that was easy.
Next we will attach the solar panel to the capacitor bank. Solder the + lead of the solar panel to the anode (blank side) of one Schottky diode, then the cathode (striped side) of that diode into the anode (blank side) of the second Schottky diode... then the cathode (striped side) of the second diode to the + lead of the capacitor bank. Finally, the - lead of the solar panel goes to the - lead of the capacitor bank.
The last step of in the build is wiring the capacitor + and - into the + and - of the 5v boost board, then the OUT lines of the 5v boost board to the V and G of the USB-C out board...
Then just stuff it all in the case... and use 3 m3x16mm bolts to hold it all together.
Ask questions if you need, but it's just a small personal project I wanted to share... Enjoy ;)
Other Info:
- We use 2 Schottky diodes because a 6V panel can put out more voltage than the 5.4V capacitor bank can handle. Each Schottky diode takes a .4V drop, so 6v gets dropped to 5.2V, completely safe ;)
- The boost board I picked has a 1A max at 5V... so... it probably won't charge your phone. If you want, get a 2A 5v board... the supercaps can handle it.
- When the supercapacitors are empty, it won't charge anything, even in direct sunlight... let the sun charge the caps before trying to charge a device.
