Are there any places that have plugs where I can charge my camera batteries and phone in the Smokies, like at either Newfound Gap or Clingman's dome? I am bringing an Ankor external battery, but I am not sure if that will be enough juice if I take a lot of video. I have a solar charger but would rather not carry the weight, and am not even sure if it would have enough trickle juice to do much.

If you want to lecture me about leaving my electronics at home, read my question. I wasn't asking for opinions about whether or not I should carry my phone and you can save the snarky remarks about the shelters having plugs. (that is called a preemptive troll strike! lol)
