Power
The performance of the tool, the maximum rotation speed of the motor and how well the device handles with thick and coarse hair depends on the power of the electric motor. So, for cutting thick head hair, you need a clipper with a power of at least 15 W, the performance of such a device is usually enough to ensure a motor rotation speed of 10,000 rpm. But there are also more
powerful clippers(from 20 W). Trimmers for beards and mustaches usually need 5 W of power. Such models most often have a performance of 3,000 – 5,000 rpm.
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.
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.
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.
