Longer outages and heavier loads
A portable generator can keep working while you have fuel. Check running output, the largest startup surge, fuel-specific ratings, voltage, and safe outdoor placement.
Size my generatorGENERATORS
Portable generators, sized without the guesswork
Compare inverter, conventional, gasoline, propane, and dual-fuel models by the work they need to do—not the largest number on the box.
START WITH YOUR LOAD
Generator or battery backup?
Pick the power source that fits how you will use it, then check your watts before ordering.
Quiet power for indoor essentials
A battery power station can support a refrigerator, internet, lighting, and small devices without combustion exhaust. Calculate usable watt-hours and a realistic recharge plan.
Compare backup systemsFuel-burning generators must run outdoors, away from doors, windows, and vents. Never backfeed a home. Product fit and Amazon availability must be checked on the retailer page before purchase.
TOP PICKS
Compare generators for your essential loads.
Choose by the job you need done. Every pick includes the main reason it stands out and the tradeoff to check before ordering.
| Model | Continuous / peak output | Fuel | Voltage | Best starting point |
|---|---|---|---|---|
| Honda EU2200i | 1,800W / 2,200W | Gasoline | 120V | Refrigeration and modest cord-connected loads |
| Westinghouse iGen5000DFc | Gas: 3,900W / 5,000W Propane: 3,500W / 4,500W | Gasoline or propane | 120V | More simultaneous essentials and remote start |
Need a 240V well pump? Neither of these single units supplies 240V. Confirm voltage and the safe connection plan before choosing from wattage alone. Compare exact models below; Amazon search results may include accessories or other versions.

GENERATORSQuiet, proven small-load backup
Honda EU2200i
A compact inverter format, strong dealer network, and parallel capability make it a durable benchmark for essential loads.
Before buying: Gasoline only, premium price, and not enough output for multiple large motor loads.
GENERATORSPortable fuel flexibility
Champion 2500W dual-fuel inverter
Light weight and propane compatibility make it convenient for refrigeration, lights, electronics, and charging.
Before buying: Propane output is lower than gasoline output; this class is not whole-home backup.
GENERATORSMore circuits without an open-frame unit
Westinghouse iGen5000DFc
Dual fuel, inverter power, wheels, electric start, and higher running output fit a broader essential-load panel.
Before buying: Its wheels help with moving a heavy unit. This single generator supplies 120V, not 240V; verify the exact outlets and connection plan.
GENERATORSPortable essential loads
Champion 4,000W dual-fuel inverter
A current, relatively light inverter design with gasoline and propane flexibility, electric start, and CO shutoff protection.
Before buying: The starting-watt headline is not the continuous rating; confirm the exact running output on each fuel.
GENERATORSHigher-output inverter backup
Champion 9,000W open-frame inverter
It pairs 9,000 starting and 7,250 running watts with inverter operation and a published 10.5-hour quarter-load gasoline runtime.
Before buying: Open-frame equipment is still large and audible. Verify outlets, voltage, transfer equipment, and fuel burn at your expected load.
GENERATORSPremium tri-fuel output
DuroMax XP15000HXT+
A current 2026 high-output model with gasoline, propane, natural-gas capability and electronic fuel injection.
Before buying: Large generators demand serious fuel, storage, handling, maintenance, and a professionally designed home connection.
GENERATORSLightweight basics
Champion 2,500W dual-fuel inverter
A compact dual-fuel format covers a carefully managed refrigerator, electronics, and lights while keeping propane available as a storage-friendly fuel.
Before buying: Limited continuous output requires active load management, especially when compressors start.
GENERATORSPremium dual-fuel inverter output
DuroMax XP11000iH
A high-output dual-fuel inverter option for owners who need more capacity and want fuel flexibility.
Before buying: Confirm current specifications, receptacles, transfer-equipment compatibility, weight, and real fuel consumption before committing.
GENERATORSConventional home backup
Generac GP9500E TF
The manual publishes separate running ratings of 9,500W gasoline, 8,550W propane, and 7,000W natural gas, making the fuel tradeoff unusually clear.
Before buying: It is a large conventional portable generator; plan for noise, handling, fuel consumption, and a correct electrical connection.
BUYING BASICS
Know what matters before checkout.
Choose the fuel strategy
Gasoline is widely available but degrades in storage. Propane stores longer and burns cleaner. Dual-fuel models give you options when supply is uncertain.
Running watts vs. starting watts
Motors in refrigerators, pumps, and air conditioners can briefly require much more power when starting. Size for the largest likely surge.
Safety is part of the system
Never run a fuel-burning generator indoors, in a garage, or near openings. Use outdoor-rated cords and a professionally installed transfer solution for home circuits.
