So I can use my PSPgo therefore, my MP3 player and my mobile phone. The small part is really an all-rounder, good that you can charge it via USB only without the appropriate charging cable is already an annoying matter, but in my opinion not in itself a reason not to buy him. Especially when compared to other alternatives, he convinced me I had some time ago a AA battery - Adapter and was a pain because you always have the bag full of AA - had batteries.
So small, quite powerful, all in all a compact recommendable device!
