Is A 12kW Generator Suitable For Me?

A 12kW generator, as we have previously said, is a very powerful unit indeed. With 12,000 watts of power on tap, you’d be more than able to provide backup power to a home, or indeed power something on a larger scale such as a construction site and its machinery.

On the other hand, if you’re looking for a generator that you can, for example, plug smaller electronic devices straight into to charge or use at the same time, a large 12,000-watt generator may not be suitable for you. Generators that are in this size range often do not come with inverters. Generators with inverters put out safe power that can be used with all electronic devices, no matter how small and sensitive they are. If you’re in need of power for smaller devices, be sure to consider this.
