250 watts is a reasonable amount of power for a hand mixer, especially for occasional or light use. It should be able to handle most basic mixing tasks such as creaming butter and sugar, beating eggs, or mixing batter for cakes or cookies. However, for heavy-duty use or larger mixing tasks, you might want to consider a model with higher wattage. Also, remember that wattage isn’t everything when it comes to performance. The design of the beaters and the motor’s efficiency can also significantly impact a mixer’s performance.
