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.
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.
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.
Weight
The weight of the clipper/trimmer is especially important when the device is planned to be used often and for a long time. The
less the clipper/trimmer weighs, the less the user's hand will get tired. Of course, there is a direct relationship between the mass of the device and its performance. Powerful clippers/trimmers use a larger and heavier motor. Additionally, the weight of the device increases due to the presence of a battery pack.
