Levels with connection to the mains 230 V

Electricity grid

— devices from this category can operate both from autonomous power (batteries or accumulators), and from a conventional outlet. Basically, this feature is found among traditional laser levels.

In general, the ability to work from the network provides additional convenience and significantly expands the possibilities for using the device. So, if there is an outlet nearby, you can use it, saving battery power and not worrying that the device will turn off due to the exhaustion of energy reserves. And some models are also capable of recharging their own batteries during such work. But if you plan to work mainly in open areas far from power grids, you should not specifically look for a device with a connection to a power outlet, since this function inevitably affects the cost.
