Ups Sp.Def gain, but lowers Speed.
Power Band accelerates Special Defense EV training. When your Pokémon defeats an opponent while holding this item, all party members that gain EVs (including Exp. Share holders) receive an extra +8 Sp.Def EVs.
The in-battle Speed reduction doesn't affect your permanent stats. **Important:** The bonus only applies if the holder defeats the opponent—switching loses the bonus. See the [IVs & EVs Guide](/guides/ivs-evs#power-items) for details.
