Its dual fuel capability allows you to run it on gasoline or propane, with propane offering cleaner, more efficient, and longer-lasting fuel storage. This flexibility can be very useful during emergencies or extended use.

It comes with a strong 670cc engine and durable all-copper windings designed for longevity. Starting the generator is simple thanks to the push-button electric start and remote control, which adds convenience especially in bad weather. The digital control panel provides useful info like voltage and runtime, helping you monitor performance easily.

For connectivity, it offers a variety of outlets, including multiple household 120V plugs and heavy-duty 120/240V outlets, plus a 50-amp transfer switch-ready outlet, allowing you to safely power many devices or connect directly to a home's electrical system. While weighing 345 pounds, it includes wheels and a handle kit to aid portability, though it may still be challenging to move by one person over rough terrain. An important safety feature is the built-in CO Alert system that automatically shuts the unit down if carbon monoxide is detected, which helps protect your family. This generator suits homeowners needing reliable, flexible whole-house backup power, as well as RV owners and jobsite users who require robust and versatile fuel options. It balances strong performance with useful safety and convenience features for serious power needs.

With an impressive power output of 13,000 watts, it can easily support essential appliances and even larger systems during a storm. Its dual-fuel capability allows users to run it on either gasoline or propane, giving great flexibility and cost-effectiveness, especially since propane burns cleaner and has a longer shelf life.
