Fixed combs
Clippers and trimmers are often equipped with fixed-height removable combs. The more combs in the kit, the smoother transitions the device can make. The standard set usually includes 3-5 combs, more advanced models may have 7-10 combs of a fixed height in a set.
Haircut length
The cutting height is influenced by the type of cutting element and the inclusion of detachable combs. Toothed blades can trim hair as short as 1 mm. By coupling a toothed blade with a detachable comb, the cutting height can range from 2-3 to 20, and even 30 mm – the precise height hinges on the provided comb attachments. There are defined minimum and maximum cutting heights. The minimum pertains to the blade's inherent capabilities, devoid of attachments. The maximum cutting height is determined by the detachable comb type.
Blade width
The width of the operating tool (blade) of the clipper. A wide blade is important for head hair trimmers, as it allows you to capture more hair in one pass and cuts faster. In turn, beard and mustache clippers use narrower knives, which is useful for fine work to give facial hair the desired shape.
Number of revolutions of the motor
The speed of rotation of the motor of the clipper. The speed of movement of the blades directly depends on this parameter, and the quality of the haircut, in turn, depends on it: the faster the blades move, the faster and more accurately the clipper cuts.
Number of speeds
The device's range of adjustable speeds is noteworthy. While most clippers typically operate at a single standard speed, there are models with dual speeds, often referred to as
turbo. More advanced variations have been developed by certain manufacturers, featuring 3, 4, or even more speeds.
Clippers equipped with variable speeds are designed to effectively manage denser hair by increasing the motor's revolutions.
Operating time
The typical duration of uninterrupted operation for a clipper powered by a self-contained source (battery or rechargeable batteries, refer to Power Source) without requiring a recharge or battery replacement. Extended continuous operation time becomes particularly crucial when intending to use the clipper in locations where recharging or battery changes are unavailable, such as during long trips.
Charging time
Time to fully (from 0 to 100%) charge the battery of the clipper. For rare cases of using the model, charging time is not so relevant, but for everyday use it is better to choose
fast charging clippers.
Charge level indicator
The charge level indicator allows you to know the status of the battery, its degree of charge. Achieved using the built-in display or LEDs.
Mains 110 / 230 V
The clipper offers the capability
to adjust its operating voltage, typically ranging between 110 and 230 V. Given the varying electrical network voltages across different regions (e.g., 230 V in Europe, 110 V in North America), this feature proves advantageous when using the clipper abroad. Some devices possess an automated voltage adjustment feature, requiring no user intervention, while others necessitate manual adjustment. It's important to emphasize this aspect before commencing clipper operation, and in cases of manual adjustment, it's crucial to verify the correct setting on the switch.
