This Generac GP1200i unit has a plethora of great features and specs that are almost similar to all the commercial Generac generators and thus you can enjoy the high-end tech of Generac in this entry-level gadget.

This unit is precisely not an entry-level device but since it has an affordable price with an entry-level tag and can be considered suitable for low-wattage needs it is placed in this category.

Based on the Generac technology vested in this generator you can easily have top-notch performance in this wallet-friendly unit.

The Generac 1200i has both the True Power Technology and the advanced Power Rush Technology that makes this device at par with the strong competitors by Westinghouse and other popular brands in the same price category.


This Generac generator has minimal power that is due to its low wattage strength. It has 1200 starting watts which are about half the running watts of the other I-series generators of Generac.

But you don’t have to worry about the low wattage of this generator because this is the ultimate reason you are looking out for this device.

The 1200 starting watts will give you 1000 running watts which are way more than many devices that have an enormous gap between the surge watts and running wattage.

The GP1200i will make use of its Advanced Power Rush Tech to boost the starting watts and this explains the reason why the difference between running and peak watts here only amounts to 200 watts.

With the power of 1000 watts, you are good enough to run a 12,000 BTU air conditioner and this means you can use this device very smoothly for your RV.

If you have several appliances in your RV that can’t be run simultaneously with this low-power generator then you can make use of its parallel kit to enhance your power.


You don’t have to worry about the runtime of this device at all because with a limited load to carry on its outlets, this generator is cool and calm enough to keep running for hours.

You can have 10.75 hours of continuous power with this tiny power backup tool. This 10.75 hours runtime is only available at 25% load carrying capacity and increasing the load to 50% will decrease the runtime by half will be around 5.8 hours.

Fuel Capacity:

Generac GP1200i generator is meant to be an extremely portable device with only 36 pounds of weight therefore having a large and bulky fuel tank doesn’t go with the overall concept here.

This cool and compact buddy will allow you to fill it with 1 gallon of gasoline fuel. With its smart and fuel-efficient engine, you can keep using it for a good enough 10.75 hours on the suggested load.

Noise Level:

It is also the best unit in consideration of your neighbors. The Generac GP1200i produces an extremely low level of noise that will give you glimpses of a silent device.
