<p>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.</p><p>Companies like Bluetti and Jackery make nice dedicated Solar Powerstations (<br><a href="https://amzn.to/31B1OXf,">https://amzn.to/31B1OXf,</a> <a href="https://amzn.to/3b8ou4n">https://amzn.to/3b8ou4n</a>). They are fairly expensive and the batteries can not be replaced. They have a limited number of cycles (e.g. 500).</p><p>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 ;-)</p><p>This design supports a top-of-class MPPT solar charge controller with a Bluetooth app for your phone.</p><p>I was able to use many off-the-shelf components.
