Ideal for the Construction Site or Off-Grid Use

The benefits of the Champion 2000 Watt Stackable over larger portable generators is that it is so much quieter and it uses less fuel. It uses on average about 1 gallon every 8-9 hours. This unit can even operate a full size fridge (Energy Start Rated) overnight, on less than a gallon of fuel. Compare this to the larger generators that use about a 1/2 gallon of gas every hour. The bigger generators are capable of operating more appliances at once within the house, but will use a significant amount of fuel. The items that this generator can power  allows you to function without much sacrifice. This is a big reason why inverter generators are better suited for tailgating or camping, rather than keeping the whole house powered up.
