My point is, go ahead and put in the current +/- sign. On the box, packaging, site, manual, whatever you can talk about how it'll actually work in any way.
Those that look for the +/- will find it. Those that misread it or are too thick to understand it will put them in wrong and your device will still work. And those that saw the cool picture on your device's package will play around with it and test different ways then say "waaaaay cool!"
