常見錯誤

❌This drill is very powered.
✅This drill is very powerful.
💡'powered' describes the energy source, not the strength; use 'powerful' for force or intensity.
❌I bought a powered charger.
✅I bought a battery-powered charger.
💡When the energy type matters, use the compound form with the specific source.
