Energizer induction charger all the way. I have the double one---just a tip, if you get it in-store, Walmart's price is $30, while Gamestop has it for $35. That said, I saw it used at Game Stop today for $15 (since all used charging stations are listed under one SKU. Of course, a lady bought it (at my recommendation of it being a no-brainer for that price) while I was still there.
