— battery power provides the maximum degree of battery life: the tool does not require external power sources, it can be used without problems even in the absence of sockets, and the cable, which limits mobility and can cause other inconveniences, is by definition absent. On the other hand, all this is true only with a charged battery; when the battery "is exhausted", it will still need an external source of electricity to charge it. In addition, such a power supply is only suitable for low-power tools, and battery models are significantly more expensive than those powered by 230 V. Accordingly, you should pay attention to this option only if the main characteristic of an electric planer for you is freedom of movement during operation. .
