The generator is the ideal tool to produce electricity in case of problems or on site!
Two major types of generators
Small transportable groups:
Light and compact, you can take them everywhere with you, perfect for camping, you can charge your devices (tablets, computers, phones), you can operate your household items (coffee makers for example).
Heavier machines and less maneuverable, this kind of group is ideal for construction sites or in case of power cut at home.
