— a device for charging the batteries used in the tool with the corresponding power supply. The fact is that many manufacturers nowadays use universal batteries that are compatible with a whole range of tools from the same brand; so, for example, a charger in the set may be quite suitable for a cordless grinder or drill from the same manufacturer. It is for the same reason that sets without a charger are also relevant (for cases when there is one from the already used electrical instrument).
