I wish I could figure out how to connect this to my Ring Door bell. I'm really tired of changing the battery every-time it needs charging. That is an easier task than climbing up a ladder to bring down the Arlo to charge it during the day, worse, over night.Which totally leaves me unsecured!With this solar panel, which is my second one, I can now keep my camera battery fully charged. I did a dry run where the camera "was" mounted and it was great. Now I have my camera much higher up and covering a larger area. I could not do that before because of having to use a really tall ladder every time it needed charging.It was in an area that I could not hardwire an adapter. Now not only do I not have to worry about charging the battery, the solar panel is set up to be in the sun all day long. Any system that had a built in solar panel could not be used because the sun was behind the camera.I should also let you know. you can take this camping to keep your phone charged up if you have that type of plug. I think you can also buy an adapter to plug into other types of plugs. Or you can actually cut and splice the wires. People have done that and made videos to show how.Happy customer here!
