I think Ryobi is missing a huge market opportunity. I have a ton of Ryobi Tools and Batteries (1000+ Wh worth!). I've made several prototypes that use Ryobi 18V batteries to charge USB ports or run a 13.8V regulated cigarette socket. I'd really like a tool that can charge my Ryobi batteries with Solar and be able to run other devices like a refrigerator or freezer at the same time.
Companies like Bluetti and Jackery make nice dedicated Solar Powerstations . They are fairly expensive and the batteries can not be replaced. They have a limited number of cycles (e.g. 500).
For people that only have an occasional need and already own Ryobi batteries this design may be a better option. My Goal is to get Ryobi to create and sell a real product ;-)
This design supports a top-of-class MPPT solar charge controller with a Bluetooth app for your phone.
I was able to use many off-the-shelf components. Not all are required depending on what you want to build:
The parts I used are located at: https://www.prusaprinters.org/prints/39638-ryobi-one-18v-battery-charge-adapter-for-solar-pow
I don't put links on Thingiverse any more since they started mucking with the links so they could make money off of them.
