Of course, this very much depends on what you are going to use it for; a good mincer doesn't even have to have power. In fact, you also have variants that you control by hand that can also grind a lot. If you're more into electric mincers, we recommend around 400 watts, then you can also put in somewhat harder ingredients like nuts or hard vegetables. When a chopper has a higher wattage it can also work at a lower wattage, because of this we recommend choosing one with a higher wattage.
