Nozzles
—
Built-in trimmer. Device for trimming the contours of facial hair. A trimmer is similar to a clipper, but smaller and better suited for fine work. Located directly on the body of the device.
—
Blade for hair cutting. Removable version of the trimmer (read more about the trimmer above), made in the form of a replaceable nozzle and is installed instead of the main nozzle with shaving heads. Thanks to this, the trimmer can be made wider than the built-in trimmer, and overall more efficient.
—
Nozzle for ears and nose. The cylindrical nozzle of small diameter allows you to penetrate the inlet and ear and remove unwanted vegetation from there. It is installed mainly on top of the main nozzle.
—
Universal comb. Such a nozzle can be useful for regular care of the stubble or beard, when you need to trim, shorten, and not just shave. Length adjustment allows you to select the desired value for a particular area or depending on the image and type of "hairstyle".
Battery capacity
While higher battery capacity theoretically extends a device's operation on a single charge, practical considerations are more complex. Ampere-hours are a specific unit, comparable only among batteries with the same voltage. For differing voltages, capacity must be converted to watt-hours for accurate comparison. Furthermore, actual tool battery life depends on consumption and performance, not just battery properties. Comparing battery capacity is meaningful only when models share the same voltage and capabilities. Operating time is a more informative parameter for comparison.
Operating time
The average runtime of electric shavers on a full battery charge, without recharging, is generally overestimated due to factors like hair length, density, and trimmer usage. Manufacturer claims for runtime tend to be higher than actual usage.
Longer runtimes require heavier and more expensive powerful batteries. Most shavers offer around
45 minutes of runtime, while some models provide up to
1 hour or as low as
30 minutes of operation.
