Limitations: At 1,800 running watts, it will not power your AC or heavy appliances. It is designed for essentials: fridge, lights, phone chargers, fans, and a few small appliances. You can parallel two EU2200i units for 3,600 running watts.
Best for: Homeowners who want a reliable, quiet inverter for essential circuits. Also excellent for camping, tailgating, and RV use.
Real-World Use — Northeast Blackout: A homeowner in Vermont kept their refrigerator (400W), chest freezer (100W), modem/router (30W), LED lights (60W), and phone chargers (20W) running for 3 days on a Honda EU2200i. Total load was roughly 610W. At 25% load (eco-throttle), the EU2200i ran for 8 hours per gallon — roughly 2.5 gallons per day. Total fuel used over 72 hours: about 7.5 gallons.
2. Champion 9375/7500W Dual Fuel — Best Value
Champion's dual-fuel 9375/7500W is the best bang-for-the-buck portable generator for home backup. At under $1,000, it produces enough power to run a small central AC system or window ACs along with all your essentials — something sub-$1,000 generators rarely achieve.
Dual-fuel flexibility: Switch between gasoline (9,375W starting / 7,500W running) and propane (8,400W starting / 6,750W running) with a simple selector switch. Propane stores indefinitely, so you always have fresh fuel ready.
Limitations: At 74 dB and 208 lbs, it is loud and heavy. This is a conventional (non-inverter) generator with higher THD, so add a surge protector for sensitive electronics. It also requires manual pull-start (no electric start).
Best for: Budget-conscious homeowners who need serious wattage for multiple appliances including window AC units.
3. Westinghouse iGen4500DF — Best Mid-Range Inverter
The Westinghouse iGen4500DF bridges the gap between small, quiet inverters and large, powerful conventional generators. At 3,700 running watts with dual-fuel capability, it handles more loads than a 2,200W inverter while still operating at a conversation-friendly 52 dB.
Key features: Remote start via key fob, LED data center display (voltage, frequency, fuel level, runtime), and parallel-ready for linking two units. Produces clean power under 3% THD.
Best for: Homeowners who need more than 2,200W but still want inverter-quality power and low noise. Excellent for powering a fridge, freezer, sump pump, furnace blower, and multiple lights simultaneously.
4. Honda EU3000iS — Best Premium Inverter
The EU3000iS is Honda's top residential inverter, delivering 2,800 running watts with the same legendary reliability as the EU2200i. Its enclosed design makes it one of the quietest generators in its class at 49 dB — barely louder than a humming refrigerator.
Standout feature: Electric start with recoil backup. The 3.4-gallon tank provides an incredible 20 hours of runtime at 25% load.
Limitations: At $2,200–$2,600, it costs nearly as much as some small standby generators. It is also 131 lbs — heavy for a portable unit. The EU3000iS is a premium tool for those who value silence and reliability above all else.
5. Champion 4375/3500W Dual Fuel — Best Budget Pick
At $500–$600, the Champion 4375/3500W is the most affordable dual-fuel generator worth buying. It runs a fridge, freezer, sump pump, and lights on either gasoline or propane. The 3,500W running output handles all the essentials.
Best for: First-time generator buyers who want reliable emergency power without a major investment.
6. Yamaha EF2200iS — Best Honda Alternative
Yamaha's EF2200iS matches the Honda EU2200i spec-for-spec and beats it on runtime (10.5 hours at 25% load vs. Honda's 8.1 hours). Yamaha's engine is equally reliable, and the EF2200iS includes a built-in carbon monoxide sensor for added safety.
Best for: Those who want Honda-level quality with better runtime and a slightly lower price point.
7. Westinghouse WGen9500DF — Best High-Wattage Dual Fuel
At 9,500W running / 12,500W starting on gasoline, the WGen9500DF powers nearly everything in a typical home — including a small central AC unit. Dual-fuel operation with remote start and a transfer-switch-ready outlet (L14-30R) make it the most capable conventional portable.
Best for: Homeowners who need 9,000+ watts but are not ready to invest in a standby generator.
8. DuroMax XP13000HXT — Best Tri-Fuel
The DuroMax XP13000HXT is one of the few generators that runs on three fuels: gasoline, propane, and natural gas. At 10,500W running watts on gasoline, it is the most powerful portable on this list. The tri-fuel option gives maximum flexibility.
Best for: Rural homeowners or those who want the most fuel flexibility possible.
9. Generac GP8000E — Best Electric Start Conventional
Generac's GP8000E delivers 8,000 running watts with electric push-button start and a large 7.9-gallon fuel tank for 11 hours of runtime at 50% load. The Generac brand name means easy parts and service.

Best for: Homeowners who need high wattage and clean power (low THD) for homes with sensitive electronics and medical equipment.
Inverter vs. Conventional Generators
This is the most important decision after wattage. The differences are significant.
Rule of thumb: If you need under 4,500W, buy an inverter. If you need 5,000W+, a conventional generator is usually more cost-effective unless you specifically need clean power for medical equipment or sensitive electronics.
Safety Features to Look For
In 2026, portable generator safety technology has improved significantly. Look for these features.
CO shutdown technology: Generators with built-in carbon monoxide sensors automatically shut down if CO levels become dangerous. This feature is now required by UL 2201 standard and mandated in several states. Models with CO Guard (Generac), CO Secure (Champion), CO Minder (Yamaha), or CO-MINDER (Westinghouse) meet this requirement.
GFCI outlets: Ground Fault Circuit Interrupter outlets prevent electrocution. Most modern generators include GFCI-protected 120V outlets as standard.
Overload protection: Automatic circuit breakers prevent generator damage from excessive loads.
Low-oil shutoff: Automatically stops the engine when oil drops below safe levels, preventing catastrophic engine damage.
Carbon monoxide from portable generators kills approximately 70 Americans every year. NEVER run a portable generator indoors, in a garage (even with the door open), or within 20 feet of any window, door, or vent. See our complete CO safety guide for details.
Essential Accessories
Real-World Example — Transfer Switch Value: A homeowner in Alabama installed a $350 manual transfer switch with their Champion 7500W generator. During a 48-hour outage, they powered their entire essential panel — furnace blower, refrigerator, freezer, sump pump, well pump, and lights — from a single cord to the transfer switch. Without it, they would have needed 4–5 extension cords snaking through windows with no ability to power their furnace or well pump.
Real-World Example — Dual Inverter Parallel Setup: A homeowner in Colorado runs two Honda EU2200i units in parallel (3,600W combined) to power their gas furnace, refrigerator, sump pump, Wi-Fi, and a medical CPAP machine during winter outages. Total investment: $2,400 for both generators + $30 parallel cable. The system is whisper-quiet at under 52 dB and produces hospital-grade clean power for the CPAP.
