Roman Lights USB battery pack uses three D batteries (not included) to power LED light sets that come with the USB connector. The portable battery pack allows you to easily power LED light sets indoors and outdoors in areas where power is not available, such as fences, trees, bushes, tents, banisters, foyers and mantles. It can also be used on boats, campers, golf carts and other vehicles. The battery pack easily hides within trees, wreaths and areas where you do not want to drag a power cord to. Power an entire 7' tree with a 1,000 LED light set, place the battery pack within the tree, and put the tree anywhere you desire. Light your boat for the family cruise around the lake, or a float in the Homecoming parade. The uses are endless.
