Shaker volume
The working volume of the shaker supplied with the device.
For more information about such containers, see "Shaker (travel bowl)". And on the one hand, the actual capacity of the shaker directly depends on the volume, on the other hand, its dimensions, as well as the requirements for engine power. However, in most models, this indicator ranges from 300 to 700 mL, less often up to 1 liter — these values are considered optimal, taking into account the specifics of the use of shakers.
Power
The rated power of the device, in fact, is the power of the engine installed in it.
The higher this indicator, the more performant this model is, the more suitable for “heavy” work and the more applications can be provided in the design. For example, in the case of mixers (see “Appliance type”), a power of up to 250 W is considered good for liquid products; for more solid tasks, like kneading tough dough, you should pay attention to more powerful models. Detailed recommendations on optimal power can be found in special sources.
Note that powerful devices are usually equipped with more durable nozzles that can withstand high loads.
Weight
The weight in this section can be confusing, since manufacturers do not indicate the mass of the main working tools of the equipment. Accordingly, the greater the number of accessories in the kit, the greater the total weight and this parameter will be necessary only at the time of purchase in order to understand how many extra kilograms you will have to carry home.
