How To Choose The Best Cheap Inverter Generator?
There are some points you need to keep in mind when choosing the best cheap inverter generator for your next camping trip or unexpected power outages.
Determine the Size You Need
Selecting the right size generator (running watts and starting watts) depends on your demands, in other words, the devices you want to power at the same time.
Running watts are essential in keeping the items running, while starting watts are the amount of power needed for a few seconds to start motor-driven appliances such as refrigerators, air conditioners or power tools. Starting watts corresponds to the maximum wattage the generator can produce.
Start by making a list of what you can’t survive without during a blackout as well as their running watts and starting watts.
Then add up all the startings watts and compare to the starting watts of the generator. If needed, you can buy two and parallelize them to add their wattages. However, it’s worth mentioning that you will have to buy separately a parallel connection in this case (about 50$).
Noise level is important
Inverter generators are usually really quiet. However you might require a super silent one. Thus you will have to compare their noise level measured in decibels. The lower, the better. Know that a human conversation is about 60 dB.
Running time matters
When looking for cheap inverter generator, you will need to look closer at how long the generator can last. The longer, the better. The average tends to be around 7 hours.
The main characteristic for run time is the tank capability. A big tank offers generally long run time but this may impact the ergonomy of the inverter generator.
In addition, some inverter generators have technology to save fuel such as ‘eco mode’ or ‘idle control’. Keep an eye on those features to minimize your fuel consumption.
The Outlets you require
Every inverter generator have at least 2 120V outlets at your disposal. However, some might have more options to offer you such as 12V and USB plug.
An inverter generator is made to be portable. It is much lighter than a traditional generator. However be aware that it’s still around 50 lbs. Some offers wheels, handles and so on. Keep this in mind.

Why would I need an inverter generator?
While offering the perfect size for your cars, trucks, RVs and small garages, the inverter generators is more fuel efficient than their conventional counterparts, saving your money and reducing emissions. Moreover, inverter generators never produce operating noise louder than a normal conversation.
Do inverter generators run on gas?
Yes. Beside gas, they might also run on propane and diesel.
What can you run on a 2000 watt generator?
Here are the list of common appliances that a 2000 watt generator can power:
Toaster (1200 watts)
Coffee maker (1000 watts)
Microwave (1000 watts)
Refrigerator (750 watts)
Freezer (600 watts)
Portable electric heater (1200 watts)
Ceiling fan (140 watts)
Computer (150 watts)
Television (250 watts)
Is pure sine wave inverter necessary?
While a modified sine wave inverter is cheaper than a pure sine wave inverter, some of your devices are exposed to the risk of being damaged.
Pure sine wave inverters offer cleaner power, like the pure AC we receive from the power stations, for your sensitive devices such as cellphones, laptops. Even refrigerators and microwaves run more efficiently on pure sine wave.
Moreover, a pure sine wave inverter has lower THD (Total Harmonic Distortion). Distortions, which are the unwanted part transferred along with the pure signal, are useless because they get wasted as heat energy. That’s why pure sine wave inverters are cost effective and helps in reducing electricity bills!
Can an inverter generator run a refrigerator?
Yes you can run a refrigerator with a 2000 watt inverter generator if you plug into one single outlet at a time.
We hope our list of the best cheap inverter generators will help you find the best solution for your next power outage or your camping trip. Thank you for reading and don’t hesitate to let us know if you have any trouble buying and using your generators!
