Without a doubt Herd 360 is the pioneer in commercially available external power and battery boxes for cellular game cameras. There were a few options for some of the camera companies, but they seemed to just be an after thought and not really able to provide long term power to cellular trail cameras allowing the user to enjoy the benefits of cellular cameras by not having to visit it frequently swapping batteries. We offer completed boxes as well as DIY (do it yourself) parts kits. All of our ready made boxes and diy kits come with Herd 360's exclusive and extremely popular rodent chew-proof cable. If you don't see what you are looking for please feel free to reach out and maybe we can help. Thank you.
