- Warranty
- 3 Years residential; 12 months commercial
- Engine
- Honda GXR120, 121cc displacement
- Outlets
- 20A 125V Duplex
- Noise level
- 57 dB(A) @ rated load; 48 dB(A) @ 1/4 load
Reasons to buy

The Honda EU2200i is our Best Overall because it pairs very low noise, 48-57 dB depending on load, with a compact 47.4 lbs build. It suits quiet-minded homeowners who want to power essentials during outages. It is also the most widely recommended pick here, with 11 independent expert guides behind it.
Keep reading about Honda EU2200i
Output is 1800W rated and 2200W peak, delivered as a clean sine wave with THD under 3%, which suits sensitive electronics. Safety and convenience features include CO-MINDER carbon monoxide detection, Oil Alert, and a Bluetooth-enabled My Generator app for remote operation and maintenance tracking. The Eco Throttle system stretches a single 0.95 gallon tank to between 3.2 and 8.1 hours, depending on load. The residential warranty is 3 years.
The trade-offs are real. The 1800W rating limits how many appliances you can run at once, and the runtime is only 3.2 hours at rated load on one tank. Starting is recoil only, with no electric start. Published expert scores vary widely: RightGenerator gives it 7.3 out of 10, PropaneVA 9.3, GeneratorDecision 9.5 and ShopSavvy 6.5, for an average of 8.2. It is best for small, essential loads rather than a whole house.
Westinghouse iGen2200: Best Value for Quiet, Expandable Backup
Best for: Budget buyers wanting quiet backup with expansion option
The Westinghouse iGen2200 delivers quiet, clean power in a light, portable package at a budget price tier. Parallel capability gives room to grow, making it a smart value for small-scale backup.
- Weight
- 46.3 lb. (21 kg)

- 5.7
The Westinghouse iGen2200 is our Best Value pick. It delivers quiet, clean power in a light package at a budget price tier, with the option to add a second unit later. It suits budget buyers who want quiet backup for essentials and some room to grow.
Keep reading about Westinghouse iGen2200
It is rated at 1800W running and 2200W peak. Noise is listed at 52 dBA, helped by a double-insulated acoustic enclosure and low-tone mufflers. At 46.3 lbs with a built-in carrying handle, it is the lightest unit in this roundup. The 1.14 gallon tank gives up to 12 hours at 25% load in economy mode, and THD is 3% or less. It is parallel capable, so pairing it with another compatible generator doubles the power capacity. Besides the 120V outlet, there are two USB ports.
The main limitation is the same as the Honda's. 1800W covers only essential loads, and the single duplex 120V outlet limits direct connections. More power means buying a second compatible unit. Expert opinion is split: PropaneVA scores it 9.6 out of 10 and Tents N Trees 8.9, while RightGenerator gives it 5.7, for an average of 8.1. It has been recommended in 5 expert guides. The warranty is 3 years limited.
WEN DF680iX: Premium Pick for Dual-Fuel 240V Power
Best for: Homeowners needing high-wattage, dual-fuel backup with 240V
The WEN DF680iX offers much more power and fuel flexibility than the small inverter units, with 240V output and electric start. It trades portability and quietness for capacity, suiting whole-home essentials.
- Weight
- 94.8 lbs
- Output

- Louder at 64 dB at quarter load
- Smaller 2.9-gallon gasoline tank than some rivals
- RightGenerator
- 6.9
- VettedHomeGear
- 8.8
The WEN DF680iX earns the Premium Pick label for capability rather than price. It sits in the budget price tier among the products compared. It suits homeowners who need high-wattage, dual-fuel backup with 240V output. It is the only pick here that runs on either gasoline or propane.
Keep reading about WEN DF680iX
Output is 6800W surge and 5100W rated on gasoline, or 6000W surge and 4500W rated on propane. That is well above the small inverter units. The 240V bonded-neutral output supports Level 2 EV charging, and the outlets include an L14-30R (120V/240V), two 120V 5-20R, a TT-30R, a 12V DC and two USB ports. It has electric start with a recoil backup and keyless push-button operation. Safety comes from the CO Watchdog sensor, which shuts the unit down if it detects dangerous carbon monoxide. THD is under 1.2%. Runtime is 6.1 hours at 50% load on gasoline and 9 hours on propane.
You pay for that capacity in portability and quietness. It weighs 94.8 lbs and is rated at 64 dB at quarter load. The 2.9 gallon gasoline tank is also listed as a smaller one than some rivals. It has 2 expert-guide recommendations, the fewest in this group, so there is less independent validation than for the Honda. Its warranty is 3 years limited.

The Champion 201318 is an Also Great pick for homeowners and RVers who want long runtime and built-in safety. It is rated at 4500W starting and 3500W running, enough for many home essentials. It has been recommended in 5 expert guides.
Keep reading about Champion 201318 4500W Inverter
Its standout is the 14 hour runtime at quarter load on a single 2.3 gallon tank. The CO Shield system shuts the unit off automatically if carbon monoxide builds up. Noise is rated at 61 dBA, measured from 23 feet. Clean Power output keeps THD under 3% for sensitive electronics. Outlets are a 120V duplex (5-20R), a TT-30R for RVs and a 12V DC automotive port. You can double power with the optional Parallel Kit, and the warranty is 3 years limited.
The drawbacks are weight and flexibility. At 92.2 lbs it is heavy to move, it runs on gasoline only, and it has fewer outlets than some larger generators. It is a practical mid-range choice for moderate home backup rather than a grab-and-go unit.
Oxseryn 4400W Inverter Generator: Also Great for More Power, Less Weight
Best for: Buyers needing more power in a lighter package
The Oxseryn 4400W gives strong running power at a relatively light 56 lbs, with long ECO-mode runtime and an RV outlet. It is a capable pick for bigger loads, though it is noisier and has a shorter warranty.

How to Choose the Best Inverter Generators for Home Backup
Start with what you need to run
List the essentials you want powered during an outage and add up their running watts. Check each item's startup surge as well. The Honda and Westinghouse suit small essential loads, with 1800W of running output. The Champion and Oxseryn, at 3500W and 3400W running, handle more at once. The WEN, at 5100W rated on gasoline, is the one for larger loads and 240V needs.
Weigh noise against output
The quietest units here are also the lowest-output ones. The Honda is rated at 48-57 dB and the Westinghouse at 52 dBA. The bigger units are louder, and the open-frame Oxseryn is the loudest at under 72 dBA at 23 feet. If neighbours or sleeping areas are close, quiet may matter more than extra wattage.
Think about fuel and runtime
Runtime depends on load, so check the figures at the load you expect. The Westinghouse lists up to 12 hours at 25% load, and the Champion and Oxseryn list 14 hours. The WEN is the only dual-fuel pick, which helps if you prefer to store propane. Remember that the Honda's 3.2 hours at rated load means more refuelling when the unit is working hard.
Check safety and start-up
The Honda (CO-MINDER), WEN (CO Watchdog) and Champion (CO Shield) include carbon monoxide protection. Whichever you buy, run it outdoors and away from windows and doors. Also consider starting. The WEN has electric start with a recoil backup, while the Honda is recoil only.
Consider weight and expansion
The Honda (47.4 lbs), Westinghouse (46.3 lbs) and Oxseryn (56 lbs) are much lighter than the Champion (92.2 lbs) and WEN (94.8 lbs). If you want to start small and grow, the Westinghouse is parallel capable with a second compatible generator. The Champion can be paralleled with its optional kit.
How We Picked
We compared inverter generators using manufacturer specifications and independent expert recommendations. We looked at running output, noise ratings, runtime, weight, outlets, safety features and warranty. We also counted how many independent expert guides recommend each model and cited published expert scores where they exist. This guide is not based on hands-on testing, and we do not quote prices because they change often. Where a spec is listed in different ways, such as noise at different loads or distances, we have kept the manufacturer's wording.
Bottom Line
For most homeowners who only need essentials during an outage, the Honda EU2200i is the best overall choice. It is very quiet, compact and well recommended, though its 1800W rating is limited. The Westinghouse iGen2200 is the pick if budget matters and you like the option of adding a second unit. If you need more capacity, the WEN DF680iX offers dual-fuel flexibility, 240V output and electric start at the cost of weight and noise. The Champion 201318 and Oxseryn 4400W sit in between, offering 3500W and 3400W of running power. Choose the Champion for runtime and CO shutoff and the Oxseryn for lower weight.
