We've slowly been upgrading the tree stands that we use for deer hunting and recently started dropping batteries in with solar panels to top them off. The primary use has been to wire in some lighting to make it easier to get set up in the morning and pack up in the evening. But, it gives the added benefit of having 12v DC power available for topping off phones, iPods, or even running an iPad or netbook like my uncle likes to do during the long mid-day hours when the deer don't move around as much.Of all the various options I found to add power ports to the tree stands that I looked at this was by far the easiest I could find. I was easily able to splice two of these into the 12v power line I have coming off the battery and then use a couple of pipe straps to hold them in place. It may not be the prettiest piece of wiring ever, but hey I have power in my tree stand now.
