Lid for blades
The lid prevents contamination of the working nozzle of the remover and its contact with foreign objects. This piece of equipment is useful for storage and transportation. Of course, with proper packaging, the remover can be stored/transported without a lid — however, such packaging is not always available, and the lid, in turn, often allows you to do without improvised packaging at all.
Number of revolutions
The speed of rotation of the motor of the remover, expressed in revolutions per minute. The speed of movement of the blades directly depends on this parameter, and on it, in turn, the quality of lint removal: the faster the blades move, the more efficiently the lumps are cut.
USB charging
The ability to charge the battery of the device
from the USB port. This function can be useful when traveling: if necessary, the battery of the device can be recharged from the Power bank or the USB port of the computer. The connector in the device itself comes in several varieties, in particular, microUSB and USB C.
Operating time
The operating time of the battery-powered lint remover (see above) on a single battery charge. It should be noted that this parameter is quite approximate, because the actual operating time is highly dependent on the intensity of the load on the operating nozzle. In addition, manufacturers can indicate the battery life of the machine in different ways: some provide data at an average load, others at idle. However, this information makes it possible to assess the battery life of the device.
For models powered by batteries, this parameter is not indicated: different brands of batteries vary greatly in performance, so the actual operating time is determined primarily by the quality of the replaceable parts.
Charging time
The time required to fully charge the battery (from zero to 100%) in properly powered lint removers (see above). This information allows you to estimate how long pauses in work will be required to charge the battery. (Although some models, supplemented by mains power, are able to work while charging).
