What it is
The Westinghouse iGen2200c is a small gasoline-only inverter generator built around a 79cc OHV engine. It delivers 1,800 running watts and 2,200 starting watts, with a 1.14-gallon tank running up to 12 hours at a quarter load. It is the safety-upgraded sibling of the plain Westinghouse iGen2200, and the "c" is not a cosmetic difference: this model adds an automatic low-oil and carbon monoxide shutdown system the original iGen2200 does not have.
The control panel includes two 120V household outlets with rubber covers and two USB ports for charging phones and tablets, plus a simple pull-cord start. At 47.4 pounds with a built-in carrying handle, it is a genuine one-person carry, and it ships EPA and CARB compliant, meaning it is legal to buy and use in all 50 states, including California.
Why it works
This generator earns its place with a straightforward set of real advantages:
CO shutdown where the plain iGen2200 has nothing
The base iGen2200 ships with no carbon monoxide detection at all. The iGen2200c adds an automatic sensor that monitors CO levels near the unit and shuts the engine down before they become dangerous. That is a meaningful safety upgrade in the same product tier, not a marketing refresh.
Genuinely quiet operation
At 52 dBA, this generator is quieter than an average conversation, thanks to a double-insulated acoustic enclosure and asymmetrical cooling fans. That matters for running it near a home in the evening without disturbing neighbors, and it stays this quiet without sacrificing power output.
Parallel capable for more power later
A separately sold parallel cord lets you pair this unit with a second compatible Westinghouse inverter to combine output. If your power needs grow, you are not locked into a single unit's ceiling, and the household's total harmonic distortion stays under 3% either way, clean enough for laptops, phones, and medical devices.
The one thing to know
Carbon monoxide safety is non-negotiable
Portable generators produce carbon monoxide, an odorless gas that can reach lethal concentrations indoors within minutes. The CPSC recommends placing any portable generator at least 20 feet from all doors, windows, and vents, with the exhaust pointed away from the home. Never run a generator indoors, in a garage, on a covered porch, in a carport, or in any enclosed or partially enclosed space, even with doors or windows open. This unit's automatic CO shutdown provides a backup layer of protection if levels near the generator rise, but it is not a substitute for correct placement. Install battery-operated CO detectors on every level of your home.

The other thing to know is that this is a gasoline-only unit with no propane option, so fuel storage planning matters more here than it does for a dual-fuel generator. Runtime is also modest next to some competitors: 12 hours at a quarter load is solid for this size class, but the Champion 201323 reviewed on this site runs up to 25 hours on a 20-pound propane tank. And with only two AC outlets, this is a generator for a handful of essentials at once, not a household running several appliances in parallel without the optional expansion cord.
Alternatives worth knowing
Generac GP2500i, for more running watts
More running wattage (2,200W) at a similar weight, also CARB compliant with built-in CO shutdown. The right choice if you need more headroom for appliances running at the same time. Read our review.
Honda EU2200iTAN1, for brand reputation and resale value
Similar running wattage (1,800W) with a strong reliability track record, but no built-in CO sensor and not CARB compliant. The right choice if long-term resale value and Honda's service network matter more than upfront CO protection. Read our review.
Champion 201323, for dual fuel and longer runtime
Slightly less running wattage (1,850W) at a lighter weight (43.2 pounds), with propane capability and up to 25 hours of runtime on a 20-pound tank. The right choice if fuel flexibility and runtime matter more than a rock-bottom price. Read our review.
Maintenance
Run the generator under load for 15 to 30 minutes every 30 days to keep the engine and fuel system in working order. Add fuel stabilizer to the tank for any storage period longer than 30 days, since this model runs on gasoline only.
Check the oil level before every use; the low-oil shutdown helps prevent engine damage if it runs low. Follow the manual's schedule for oil change intervals, and inspect the air filter and spark plug annually.
Westinghouse backs the iGen2200c with a 3-year limited warranty and lifetime technical support through its nationwide service network. Register the unit and keep the purchase receipt with your household documents.
NWS recommendation
If you need a quiet, CARB-legal small inverter that covers a refrigerator, lights, and chargers, and you want carbon monoxide protection built into the unit itself, the iGen2200c does the job. Skip the plain iGen2200 unless you already have a separate CO detector plan you trust completely. Test it before you need it, and place it at least 20 feet from the house with the exhaust pointed away.
