Honda EU2200i vs WEN 56235iX vs Generac GP3300i: compact gasoline inverters
Compare three gasoline-only inverters with a built-in carbon monoxide shutoff by running watts, the 30 A receptacle, the load behind each run time and how much each maker says about noise.
The decision in brief
How the options differ
All three exact US packages run on gasoline only, use recoil start and document a branded CO shutoff system. They differ in running output (1,800, 1,900 and 2,500 W), in whether a 30 A receptacle is fitted, and in how comparable their run time and sound figures are: Honda states two loads, WEN one load without a distance, and Generac publishes no sound level.

The buying guide
Package and specification details
Size by running watts, not the larger number
EU2200ITAN is rated 1800 W with 2200 W max, 56235iX 1900 W rated with 2350 W surge, and GP3300i 2500 W running with 3300 W starting. Each maker names the short-term figure differently; the running figure is the continuous one.
Only the GP3300i has a 30 A receptacle, and it is an L5-30 twist-lock, not a TT-30R. EU2200ITAN has one 20 A duplex, with the L5-30R reserved for the separate Companion version, and the 56235iX has two 5-20R receptacles plus 12 V DC and USB outputs.
At 25% load Honda states 8.1 h on 0.95 gal and Generac 7 h on 1.06 gal. WEN states only 5.7 h at half load on 1.06 gal, against Honda's 3.2 h at rated load and Generac's 4.5 h at 50% load. Half-load and quarter-load figures are not compared with each other.
Honda publishes 48 dB(A) at 1/4 load and 57 dB(A) at rated load, and WEN 51 decibels at quarter load, neither with a stated distance. Generac publishes no sound level for the GP3300i. None of these is a measured comparison.
Which of these three is sold for use in California?
Honda states EU2200ITAN is not for sale in California, and Generac names the selected variant 49ST/CSA. WEN's store page and manual make no CARB or California statement. Confirm the California status of the exact SKU with the seller.
These manufacturer specifications do not establish measured performance, noise, long-term reliability or running cost. We have not independently tested these products. Check current prices, stock and operating-space instructions with the seller and manufacturer.

Questions to check before buying
EU2200i EU2200ITAN, 49-state (US)
Honda does not state the distance at which its 57 and 48 dB(A) figures were measured, and its 2017 launch release for the earlier EU2200i listed different figures.
The Home Depot lists an EU2200iTAN4 model code; whether that suffix marks a different production type from Honda's EU2200ITAN is not established.
EU2200ITAN is stated as not for sale in California. Other type codes and the EU2200i Companion are separate products and are not covered by this record.
56235iX with CO Watchdog, individual unit (US)
WEN's 51-decibel figure states a quarter load but no measuring distance, and WEN publishes no quarter-load run time.
The manual read is dated 2021-08-19; a later production change would not be reflected in it.
The 56235i without a CO sensor is a separate SKU with its own UPC and is not covered by this record.
GP3300i with COsense 71533, 49ST/CSA (US)
Generac publishes no sound level for the GP3300i, so its noise cannot be compared with the other models here.
Generac's own documents differ on weight (61 lb on the page and 2024 sheet, 59.5 lb in the 2023 brochure) and on variant numbers and configuration (G0071533 49ST/CSA on the page, G0071531 and G0071530 50ST/CSA in the brochure).
The COsense shutdown threshold and behavior are not described beyond Generac's marketing wording and indicator labels.
