Thanx TnA, yes, that is exactly my point...most of us have RCA cables and devices sitting around, it is a connector that has been around with us for so many years and yet we don't pay much attention to it anymore. I believe that this solution will help develop even further the options we have for powering our atomizers in so many different and much simpler ways.
To me the best is that i don't need to worry about finding a good (and expensive) power supply for my heavy vaping needs. I just build my own so easy now. My 5,000 mAh sits on my desk and i use it everyday and lasts me almost 3 days without having to charge it.
I can also switch in seconds to my little nicostick boxes or magnums depending on my mood or need. I can vape with a cable attached (from USB, power box, Power supply form the wall, or) or carry my choice of power in a little box (1 X 14500, 2 X 14500, 1 X 10440, 2 X 10440, 1 X 18500, 1 X 16340, 2 X 16340). And every one was built with a minimal investment for parts (an RCA jack or plug goes for around .30 to .40 cents)
