Classic blenders rated 300–700 W suit light tasks like soups, sauces, plant milks and smoothies.

They use direct drive with no gear reduction so avoid thick pastes that strain the motor.

Power blenders up to 1500 W handle raw nut butters and other demanding blends.

All blender blades spin up to about 30 000 rpm to produce fine texture.

During heavy workloads pause periodically to let the motor cool.
