MediumRoastSteam The Niche Zero folks don’t specify the wattage of the motor, as far as I can tell. That indicates that they don’t see this as a selling point, otherwise they probably would specify it.
From a quick survey, it seems that most coffee grinder manufacturers will specify the wattage of the motor. In fact, it’s to find a grinder manufacturer that doesn’t, except for Niche. Fellows doesn’t seem to specify wattage, but they do specify torque, which is arguably a better measure than wattage.
