Cable adapter for mini-usb solar panel to new barrel plug on Ring 3 camera?

My Ring gen 1 stick-up cam finally crapped out, the battery would not charge. So they don't make the Ring 1 anymore, I had to buy a Ring 3 camera figuring it would be an ok replacement. The solar panel I have for my Gen 1 has a micro-USB plug on it and I see on the gen 3 camera's they have some kind of barrel plug adapter now? Is there a micro-usb plug to barrel adapter for the solar panel to work with the new ring camera?
