Before we move on to the best dual fuel portable generators, you must understand what to look for. Here are the top features to look for before investing in a dual fuel generator: 
1. Power Output 
Dual fuel generators measure their power output in watts. There are two power outputs: the running power output and the peak power output. A dual fuel generator will produce a power output of anywhere between 1,000 and 12,000 watts. 
That is why if you want the maximum power output, you must invest in a 12,000 watt dual fuel generator.  Of course, the best power output for your needs will also depend on other factors. 
2. The Capacity Of Fuel 
All the best dual fuel portable generators have gas tanks. The fuel capacity of that gas tank ranges from two to ten gallons. Of course, the bigger the fuel tank, the more time the generator can offer power. 
However, the fuel capacity does not relate to the amount of gas you can use. The gas is under pressure inside canisters that attach to the generator. These canisters attach with a pressure regulator and a hose.
