Buying Guide:

Now that you know the models worth investing in, it’s high time you know how to pick the ideal to buy. You need to consider the following factors if you want to get the best 3000-watt generator that meets all your needs.

Power requirements

Here you have to consider all the appliances and the electronics you need to power with the generator. You have to get their total wattage requirement and use it to find the ideal size generator. For you to do this, you need to list all the items and sum up the watts. Add all the power, including the starting and the running watts for the motor-driven appliances. Check on the user manual if the information isn’t available on the device. If the power isn’t in watts but volts and amps, then use this formula:

Watts = volts * amps

Fuel Tank Capacity and Runtime

The runtime is the time it takes for the generator to provide continuous power supply until next refill. If you need a better runtime, then you need to go with a high capacity tank. Also, you have to check the fuel efficiency of the generator before deciding to buy. High power with low fuel consumption is the best.

Number of outlets

At the time, you will find yourself with a long list of appliances and electronics to run. For you to have the best time, then you need to buy a model with a sufficient number of outlets. If you’re going to use the inverter generator on your RV, then it needs to come with an RV ready output. For the camper, a generator with a USB port and GFCI ports would be ideal.

Noise Level

Yes, an inverter generator is quiet, but some models are quieter while making your selection check on the noise levels of each model and consider the lowest.


Economy mode is a friend to those who need more fuel efficiency. It allows the engine to run in variable speeds depending on the load connected to the generator. A model with this technology is more fuel-efficient, and its engine is protected from wear.


Lastly, we have portability. Are you planning to be moving a lot with your generator? If yes, then you have to get a portable model. Which one is that? You need a model with wheels, handle, lightweight body, and compact design.
