— powered by its own battery of the original standard, which can also be made non-removable. On the one hand, such power supply has a number of advantages over replaceable batteries.

At the same time, it is batteries that can be supplied with such a device, but the battery will have to be purchased separately (or removed from another device — some manufacturers produce universal batteries suitable for different types of tools).
