I had a random thought last night to use a small solar panel I've owned for years (and rarely use) and mate it with some batteries.
I have a SunTactic sCharger-5 thats been sitting in a bug out bag for too long. I also have some extra 4400mah 3.7v pouch cells. Came up with this idea to match them together with a little charging board and a wood frame.
Traced out the panel outline, measured thickness of the panel and batteries so I could router out the battery holder section behind the panel.
Cut out with the jigsaw. Lightly sanded and a couple coats of poly.
Wired 5x 4400mah 3.7v cells in parallel. The board has a micro usb, usb-c inputs, and 2x usb outputs
Works well! I think I will use this camping more often. The sun was never out when I needed to charge something. Now I can leave this out during the day, and charge my phone at night in my tent. Used all parts I had laying around my garage.
Just plug the solar panel into the micro usb input in the board to charge with solar. You can also still plug the panel directly into a phone to charge and access the battery to charge also! The panel still pops out incase I want to use it separately.
