I'm pretty sure I already asked about this a couple years ago, give or take. Well, I'm asking about it again. I know there's a gizmo that can transfer from one sd card to another without a computer. What I don't know is what it's called, how much it costs, and how to get it. Does it require a second phone? I hope it can be used with just one, the Moto G. I could probably afford up to thirty or forty dollars for it. How would I hook it up and does it need an outlet, or would just the phone be enough?
