If you're talking about a standard 3DS charger, then yes, it will work. If you're talking about an actualy ORIGINAL DS charger from waaaaay back when... then no. Sorry.

As for the strategy guide, I'm assuming it would be in German. Unfortunately though, the only thing that is useful in that book is the armor sets as you can find more information here on the wiki and you can find it more easily.
