Looks to be similar to the Sinewave... In any case I have a Sinewave Revolution and a Forumslader. The Forumslader cost more but I freaking love it. The Sinewave is okay but definitely needs a cache battery when paired with an iPhone and isn't nearly as efficient as the Forumslader. I don't see much on the Powerbug so no comments there, sorry.
Rifraf, Best I can find it's from Poland and sold on Ebay,

I hope the OP doesn't end up in the middle of another Ebay fiasco...
