Wattage and Power Needs
When choosing an inverter generator, start by calculating the total wattage of the devices you plan to run simultaneously. For example, the PowerSmart 3800 offers 3300 rated watts on gasoline, which can power a refrigerator (700W), a sump pump (800W), lights (300W), and a TV (150W) simultaneously, totaling 1950W, well within its capacity. Always consider surge watts for motor startup; the PowerSmart provides 3800 surge watts, enough for a well pump or air conditioner.
For sensitive electronics like laptops and phones, look for a generator with less than 3% total harmonic distortion (THD). All models in this roundup meet that standard, ensuring clean, stable power.
Fuel Type and Runtime
Dual-fuel generators like the PowerSmart give you flexibility: gasoline offers higher wattage, while propane provides cleaner, longer storage life. The Westinghouse iGen2800 runs up to 12 hours on 0.98 gallons of gas in economy mode, making it fuel-efficient for overnight use. The Pulsar 2300W runs 4.8 hours at half load on 1.18 gallons, suitable for shorter trips.
Consider your fuel availability and storage. Propane is easier to store long-term but delivers slightly less power. Gasoline is widely available but degrades over time.
Noise Level and Portability
Inverter generators are inherently quieter than conventional models. The Westinghouse iGen2800 operates at 52 dBA, about as loud as a quiet conversation, while the PowerSmart is rated at 70 dBA. For camping or residential areas, lower decibel ratings are preferable. Weight also matters: the Westinghouse at 46.3 lbs and the Pulsar under 47 lbs are easy to carry, while the PowerSmart at 50.7 lbs is still manageable.
Safety Features and Certifications
Modern generators include safety features like CO sensors (PowerSmart), low-oil shutdown (Generac, Westinghouse), and overload protection. CARB compliance (Generac, Pulsar) is essential for use in California and other strict-emission states. Always check local regulations before purchasing.

Frequently Asked Questions
What size inverter generator do I need for home backup?
For essential appliances like a refrigerator, lights, and a sump pump, a generator with 2000-3500 running watts is usually sufficient. For more demanding setups, consider a 4000W+ model like the WEN GN400iM. Always calculate your total wattage needs first.
Can I run a generator in the rain?
No, never operate a generator in rain or wet conditions. Use a canopy or generator tent to keep it dry, and always place it on a level surface away from windows and doors to prevent carbon monoxide buildup.
What is the difference between an inverter generator and a conventional generator?
Inverter generators produce cleaner power (less than 3% THD) that is safe for sensitive electronics, are quieter, and more fuel-efficient because they adjust engine speed to the load. Conventional generators run at a fixed speed, are louder, and produce power with higher THD.
How do I maintain my inverter generator?
Regular maintenance includes changing the oil (every 50-100 hours), replacing the air filter, cleaning the spark plug, and using fuel stabilizer if storing for long periods. Refer to the owner’s manual for specific intervals. For more tips, see our best generators inverter for home use.
