You cannot get all of them unless you have also White2. Anyway here are the locations: Macho Brace: Nimbasa City, eastern gate (gift) Power Weight (+HP): Route 4 White2 only (in-game trade, attached to the Pokémon) Power Bracer (+Atk): can't be found Power Belt (+Def): Plasme Frigate White2 only (pokeball) Power Lens (+SAtk): can't be found Power Band (+SDef): Plasme Frigate Black2 only (pokeball) Power Anklet (+Speed): Route 4 Black2 only (in-game trade, attached to the Pokémon) Source: http://nuggetbridge.com/blogs/entry/113-ev-training-hot-spots-in-black-2-white-2/
