After a lightning strike hit the top of my mast back in 2018, some of the electrical wires got fried, including that supplying the chartplotter on my pedestal. Since then, I have been using various sources to supply my navigation pod ranging from jump starters to a 12 volt wheelchair battery. About a month ago, Ryobi power tools came out with this gadget for use with their 18 volt cordless tool batteries, of which I have an extensive collection. It has a 12 volt outlet for use with automotive and marine accessories, as well as ports for charging phones, cameras, and tablets. Can't wait to try it on my boat this summer
