Power consumption

The total power consumed by a mains-powered electric tool (see "Power Source"). It is considered the main criterion for assessing the overall capabilities of a particular model: more power allows you to achieve more speed and/or torque. However a more correct parameter for such an assessment is useful (working) power, but it is far from always indicated, and tools of the same type with similar power consumption usually do not differ much in terms of working power. In addition, data on power consumption also allows you to estimate the load on the power grid or other power source; in some cases this is unnecessary.

As for specific figures, for different types of tools, the characteristic power values will be different. For example, from 750 to 1000 W is considered a very solid indicator for a screwdriver, while for classic drills this is an average value, among such devices there are options even for 1.5 kW or more. Detailed recommendations on choosing a tool for this parameter can be found in special sources. We only note that it does not always make sense to chase the maximum values high power noticeably affects the dimensions, weight and price of the unit, despite the fact that it is far from always required.

Cable length

The length of the cord attached to the mains powered tool (see "Power Source").

The longer the wire - the farther from the outlet you can use the tool without switching it, the more freedom the user has. On the other hand, an overly long cable creates inconvenience during storage and transportation, and even during operation it can get under your feet (or even your hands). Given this, in most cases, manufacturers equip their products with network cables from 2 to 4 m long. This gives a sufficient degree of freedom without creating inconvenience, and for situations where the length of the wire is not enough, there are extension cords. Of course, even in this range, you can choose a cable for a specific situation: for example, for a city apartment 2 - 2.5 m will be quite enough, but for a construction site it is desirable to have a longer wire.
