I've got the Proporta model, and I have to say that I don't tend to use it or rely on it because I don't understand it.
It came with no instructions, but it has a button on the top. So the first thing I did when I first tried to use it was press the button. But then it lit up green and no matter how many times I pressed it afterward, it wouldn't turn off.
I also haven't had much success using it to charge my device as I use it (such as while watching a movie on a plane). I can't tell if it's working or not, and after a short while my screen dims as if it's not receiving a charge.
So if nothing else, this other model might be more useful for some folks because it sounds like you can at least tell what it's doing!
So there's my tuppence-worth:
