Best Generators For Backup Home Use: How the Top Picks Compare
Which generator offers the most power for home backup?
The WEN GN5602X leads with 5,600 starting watts and 4,500 running watts, enough to power a refrigerator, sump pump, and several lights simultaneously. The PowerSmart 3800 delivers 3,800 surge watts (3,300 running on gas), while the Westinghouse iGen2800 provides 2,800 peak watts. If you need to run multiple large appliances during an outage, the WEN is the clear winner.
How quiet is each generator during operation?
Noise matters when you are camping or have close neighbors. The Westinghouse iGen2800 operates as low as 52 dBA, quieter than a normal conversation. The PowerSmart 3800 runs at 70 dB at 23 feet, comparable to a conversation but noticeably louder. The WEN GN5602X does not list a decibel rating, but open-frame conventional generators are generally louder than inverter models. For quiet operation, the Westinghouse is the best choice.
Which model is the most portable and easy to move?
Portability is key for moving your generator from storage to use. The Westinghouse iGen2800 weighs just 46.3 pounds, making it the lightest of the three. The PowerSmart 3800 is 50.7 pounds, still manageable. The WEN GN5602X includes a wheel kit but is heavier due to its larger engine and frame. If you need to carry your generator up stairs or into a truck, the Westinghouse is the easiest to handle.
What safety features do these generators include?
All three generators prioritize safety with CO shutdown sensors. The PowerSmart 3800 and WEN GN5602X both feature automatic carbon monoxide detection that shuts off the engine if dangerous levels build up. The Westinghouse iGen2800 does not mention a CO sensor in its key features, so if you plan to use the generator near living spaces, the PowerSmart or WEN provide extra peace of mind.
Our Final Picks for 2026
Choose the WEN GN5602X if you need maximum power for running multiple appliances during a prolonged outage. Its 5,600 starting watts and electric start make it the most capable home backup in this group.
View on Amazon.comChoose the PowerSmart 3800 if you want dual fuel flexibility and clean inverter power for sensitive electronics. It runs on both gas and propane, produces pure sine wave power, and includes a CO sensor.
View on Amazon.comChoose the Westinghouse iGen2800 if portability and whisper-quiet operation are your top priorities. At 46.3 pounds and 52 dBA, it is the lightest and quietest generator here, ideal for camping or quick home backup.

Understanding starting vs. running watts
Starting watts (surge) are needed to start motors in appliances like refrigerators and sump pumps. Running watts keep them going. For example, the PowerSmart 3800 provides 3,800 surge watts and 3,300 running watts on gasoline. A typical refrigerator needs about 1,200 surge watts and 600 running watts, so this generator could run a fridge plus a few lights and a phone charger simultaneously. Always check the surge wattage of your appliances before choosing a generator.
Fuel type and runtime considerations
Dual fuel generators like the PowerSmart 3800 offer flexibility: you can switch between gasoline and propane depending on availability. The Westinghouse iGen2800 runs on gasoline only but offers up to 12 hours of runtime at quarter load on a 0.98-gallon tank. The WEN GN5602X has a 4.3-gallon tank providing up to 12.5 hours at half load. If you want longer runtime without refueling, the WEN is the better choice.
Inverter vs. conventional generator
Inverter generators (PowerSmart 3800, Westinghouse iGen2800, and WEN GN400iM) produce clean, stable power with less than 3% total harmonic distortion, safe for laptops and smartphones. Conventional generators (WEN GN5602X) are louder and may produce power with higher THD, but they often offer more watts per dollar. For sensitive electronics, choose an inverter model.

Frequently Asked Questions
Can I use these generators during a power outage?
Yes, all five generators are designed for home backup use. The WEN GN5602X includes a transfer-switch-ready outlet, making it easy to connect to your home’s electrical panel. Always follow safety guidelines and never run a generator indoors.
How do I maintain my generator?
Regular maintenance includes checking oil levels, changing oil after the first 20 hours and every 100 hours thereafter, cleaning or replacing the air filter, and running the generator monthly to keep the engine lubricated. For more tips, see our guide on size generators for home backup.
What is the difference between a portable generator and a standby generator?
Portable generators are movable, run on gasoline or propane, and require manual setup during an outage. Standby generators are permanently installed, run on natural gas or propane, and turn on automatically. Portable models are more affordable and flexible for occasional use.
Can I connect two generators together for more power?
Yes, some inverter generators are parallel capable. The Westinghouse iGen2800 and WEN GN400iM both support parallel operation, allowing you to connect two identical units to double your output. Check the manufacturer’s instructions for compatible models and cables.
