The short answer
For most homeowners and RVers, the Westinghouse iGen4500DF is the portable generator to buy. The listing gives 5,000 peak and 3,900 running watts on gas, with clean inverter power (under 3% THD) that is safe for laptops and TVs. It runs on gas or propane, starts from a key fob, has an RV-ready TT-30R outlet and stays as low as 52 dBA in Economy Mode, with up to 18 hours of run time on its 3.4-gallon tank. That is enough to keep a fridge, a furnace blower, lights and phones going in an outage.
If quiet and long-term reliability matter more than power, the Honda EU2200i is the benchmark: 48 to 57 dBA, CO shutoff and a Bluetooth app, at a premium price. The Champion 4000-Watt Dual Fuel is the value pick with almost as much power for less, and the WEN DF360iX is the budget dual fuel inverter for camping and light backup. For real home backup through a transfer switch, the Westinghouse iGen12000DFc delivers 9,000 running watts and 240V outlets.
Skip the iGen4500DF if you only need to charge phones and run a CPAP while camping; a battery power station is quieter and safe indoors. And if you want to run central AC, a well pump or most of the house through a transfer switch, it is too small: look at the iGen12000DFc. Whatever you buy, never run a generator indoors or in a garage; carbon monoxide kills.
How we picked: we compared the most popular inverter and dual fuel generators on Amazon, read what owners say after outages and camping trips, and checked each listing’s watts, fuel, noise, outlets and safety features. We don’t claim hands-on tests. Picks and price bands checked October 14, 2026.

Why each one made the list
What each pick does best, where it falls short, and the typical Amazon price when we checked.
- 1. Best Overall
Westinghouse iGen4500DF
BeastScore 93 / 100Typically $900–$1,000 on Amazon (checked October 14, 2026)The iGen4500DF hits the right size for most people. The listing gives 5,000 peak and 3,900 running watts with under 3% THD, so it can run a fridge, furnace fan, sump pump or RV air conditioner and still be safe for electronics. It takes gas or propane, and propane stores for years without going stale. Remote start from the key fob, electric start and recoil backup make it easy in the cold, and the LED data center shows fuel, load and remaining run time. Owners praise how quiet it is for its size. It is heavy, so use the telescoping handle and wheels, and propane output is a little lower than gas.
Pros- Dual fuel with remote key-fob start
- Quiet: as low as 52 dBA in Economy Mode
- RV-ready 30A outlet and parallel capable
Cons- Heavy to lift into a truck bed
- Propane gives less power than gasoline
- Too small for central AC or whole-home backup
- 2. Quietest & Most Trusted
Honda EU2200i
BeastScore 91 / 100Typically $1,150–$1,250 on Amazon (checked October 14, 2026)The EU2200i is the generator that campgrounds and contractors trust, and it is still the quiet benchmark. The listing gives 48 to 57 dBA, quieter than a normal conversation, and power for a microwave, fridge, hair dryer or small AC unit. Honda’s CO-MINDER shuts it down if carbon monoxide builds up, and the My Generator Bluetooth app shows status, sends service reminders and can stop it remotely. Owners report years of trouble-free running, which is the real reason to pay more. It is gas only, has far less power than the 4,000-watt picks, costs the most per watt, and the listing says it is not sold in California.
Pros- Very quiet: 48 to 57 dBA
- CO-MINDER auto shutoff and Bluetooth app
- Light and easy to carry
Cons- Most expensive per watt here
- Only 2,200 peak watts and gas only
- Not sold in California (listing)
- 3. Best Value
Champion 4000-Watt Dual Fuel
BeastScore 89 / 100Typically $650–$750 on Amazon (checked October 14, 2026)The Champion gets you most of the Westinghouse for noticeably less. The listing gives 4,000 starting and 3,000 running watts on gas, and 2,700 running watts for up to 25 hours on propane, which is a long stretch through an overnight outage. Power is clean (under 3% THD) with an RV-ready TT-30R, a household duplex and a 12V outlet. CO Shield shuts it off if carbon monoxide builds up, and a parallel kit (sold separately) pairs it with another Champion inverter or power station. Owners like the value and support. It is louder than the Westinghouse and Honda, and the listing does not mention electric start.
Pros- Dual fuel with long propane run time
- CO Shield carbon monoxide shutoff
- Strong price for 4,000 starting watts
Cons- Louder than the Westinghouse and Honda
- No electric or remote start mentioned on the listing
- Parallel kit costs extra
- 4. Best Budget
WEN DF360iX
BeastScore 86 / 100Typically $500–$560 on Amazon (checked October 14, 2026)The WEN is the least expensive dual fuel inverter worth trusting. The listing gives 3,600 surge and 2,900 running watts on gas, and 3,500 and 2,600 on propane, with clean power for phones and laptops. It packs a TT-30R RV outlet, two 120V outlets, 12V and two USB ports, and a Watchdog CO sensor turns it off if carbon monoxide rises. A fuel shut-off lets you run the carburetor dry before storage, which prevents the most common starting problem, and propane hooks up without tools. Owners like the size and price. It has less power than the Champion, and WEN’s dealer network is thinner than Honda’s.
Pros- Lowest price for a dual fuel inverter here
- Fuel shut-off makes storage easier
- USB ports and an RV outlet built in
Cons- Less power than the 4,000-watt picks
- Fewer service centers than Honda or Champion
- Electric start not listed
- 5. Best for Home Backup
Westinghouse iGen12000DFc
BeastScore 88 / 100Typically $1,800–$2,000 on Amazon (checked October 14, 2026)If you want to power most of a house, you need 240V and a lot more watts. The iGen12000DFc gives 12,000 peak and 9,000 running watts on gas (11,000 and 8,100 on propane) as an inverter, so it is still clean enough for electronics. A 50A 14-50R and a 30A L14-30R outlet are both transfer switch or interlock ready, the safe way to feed your panel. The listing says it runs up to 19 hours at 25% load on a 7.9-gallon tank and starts from a key fob. Owners like it as a cheaper alternative to a standby generator. It is big and heavy, and installing a transfer switch needs an electrician.
Pros- 9,000 running watts with 240V outlets
- Transfer switch ready for safe home hookup
- Inverter power with remote start and CO sensor
Cons- Heavy: it lives on wheels, not in a car trunk
- Transfer switch install adds cost
- Louder than the smaller inverters

Westinghouse iGen4500DF
Dual fuel, remote start, RV-ready and quiet, with enough power for a fridge, furnace fan and lights in an outage.
- 3,900 running watts
- Gas or propane
- As low as 52 dBA
Quick tips before you buy
Run any generator at least 20 ft from the house, never in a garage. Pick a model with CO shutoff.
List what you need on at once: fridge, furnace fan, sump pump, lights. Size for running watts, then check starting watts.
Propane keeps for years. Gas goes stale in months, so use a stabilizer or run the carb dry before storage.
Start it every month or two. Most generator failures are old fuel in a carburetor.
Quick answers
What is the best portable generator?+
The Westinghouse iGen4500DF. It gives 3,900 running watts on gas or propane, starts from a key fob, has an RV-ready 30A outlet and runs as quiet as 52 dBA, which covers outages and RV trips for most homes.
Inverter vs regular generator: what’s the difference?+
An inverter generator makes clean power (low THD) that is safe for laptops, TVs and modern furnaces, and it throttles the engine to the load, so it is quieter and uses less fuel. Regular open-frame generators are cheaper per watt but louder.
Is a dual fuel generator worth it?+
Yes for home backup. Propane stores for years and is easy to find in tanks, while gas goes stale and can be hard to buy in a storm. Expect slightly fewer watts on propane.
What size generator do I need to run a house?+
For essentials like a fridge, furnace fan, lights and phones, about 3,000 to 4,000 running watts is enough. To run most of a house through a transfer switch, including a well pump or some AC, look at 9,000 running watts or more, like the iGen12000DFc.
Honda EU2200i vs Westinghouse iGen4500DF: which should I buy?+
The Honda is quieter, lighter and has a long reliability record, but it is gas only with much less power. The Westinghouse has nearly twice the running watts, dual fuel and remote start for less money. Pick Honda for camping, Westinghouse for home backup and RVs.
Can I run a generator in the rain or snow?+
Not unprotected. Use a generator tent or cover made for running units, keep it on a dry surface and keep it outdoors and well away from doors and windows.
