Boosts HP gain, but lowers Speed.
Power Weight speeds up HP 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 HP EVs.
HP EVs benefit almost every Pokémon since more HP means more overall bulk. **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.
