Does anyone know if there are any other devices like the Skiva Battery Pack? It includes lightning output, and you can charge it by plugging it in to a computer or a wall charger. It seems really nice as there is no need for any cables at all. http://www.amazon.com/Skiva-Lightweight-Pocket-Friendly-Super-Compact-AP103/dp/B00CTFG26A Seems like this has been on the market for a few years. I find it odd that this is the only all in one integrated power bank I can find.
