- Firman W01784
- Westinghouse iGen2200
Comparison Overview
These two portable inverter generators are remarkably similar in size, weight, and output, but a few key differences separate them. The Westinghouse iGen2200 edges ahead with 1800 running watts and 2200 starting watts compared to the Firman W01784's 1700 running watts and 2100 starting watts. That extra 100 watts on each end may not sound like much, but it can make the difference when you're running a small appliance near the generator's capacity limit.
Runtime is where the Westinghouse pulls further ahead. At 25% load, the iGen2200 runs for 12 hours versus the Firman's 9 hours, giving you a full extra night of quiet power on a single tank. The iGen2200 also lists a 10-hour runtime at 50% load, a figure Firman doesn't publish for the W01784. On the noise front, the Westinghouse is slightly quieter at 52 dB compared to the Firman's 54 dB, though both are impressively quiet for gas generators.
Both units weigh roughly 46 pounds, both run on gasoline, and both carry a 3-year warranty. The Firman W01784 does hold a higher overall score of 6.14 versus the Westinghouse's 5.79, which may reflect factors like build quality or value. Buyers who prioritize longer runtime and a touch more power will lean toward the iGen2200, while those who find the Firman at a better price point or prefer its feature set may find it the smarter buy.
Key takeaways
- Westinghouse iGen2200 delivers 1800 running watts versus the Firman's 1700 running watts
- Firman W01784 earns a higher overall score of 6.14 compared to 5.79 for the iGen2200
- Westinghouse runs up to 12 hours at 25% load, 3 hours longer than the Firman
- Both weigh roughly 46 pounds and include a 3-year warranty
- Westinghouse is slightly quieter at 52 dB versus the Firman's 54 dB
- Both are gasoline-powered inverter generators suited for camping and light backup
Best use cases
Choose the Firman W01784 if you want a solid, well-reviewed inverter generator and can live with slightly less wattage and shorter runtime. At 1700 running watts, it still handles most camping essentials like a mini fridge, phone chargers, LED lights, a CPAP machine, and a small fan without breaking a sweat. If you tend to keep your loads light and don't need all-night runtime without refueling, the Firman gets the job done reliably. It's also worth considering if you find it priced lower than the Westinghouse, since the two generators are close enough in specs that a meaningful price gap could tip the scales.
Choose the Westinghouse iGen2200 if runtime is a top priority. That 12-hour runtime at 25% load is a genuine advantage for overnight camping trips, tailgating events, or situations where you don't want to wake up to refuel in the middle of the night. The extra 100 running watts (1800 vs 1700) also gives you a bit more breathing room if you plan to run a small window AC unit, a power tool, or multiple devices at once. At 52 dB, it's two decibels quieter than the Firman, which is a subtle but real difference in a quiet campground setting.
Both generators are portable enough for one person to carry and quiet enough to use without disturbing neighbors. Neither is suited for heavy-duty home backup or running large appliances like a central AC or electric dryer. They're best matched to recreational use, light emergency backup for essentials, and small outdoor events. If you're an RV camper who runs a rooftop AC, you'll likely need to look at a higher-wattage unit regardless of which brand you prefer here.
Verdict & recommendation
If your priority is maximizing runtime per tank and squeezing out every available watt, the Westinghouse iGen2200 is the stronger pick with its 12-hour runtime and 1800 running watts. If you value overall build and feature quality (reflected in the Firman's higher overall score) or find the W01784 at a noticeably better price, it remains a very capable option that covers most light-duty needs.
The honest truth is that these two generators are more alike than they are different. Both are quiet, lightweight inverter generators built for the same kinds of tasks. Your decision may ultimately come down to price, brand preference, and availability. Either one will serve you well for camping, tailgating, or keeping the basics running during a short power outage.

| Summary | The Firman W01784 is a 1700-watt inverter generator built around a compact 80cc OHV 4-stroke engine. This wattage class handles household essentials like refrigerators, power tools, and multiple small appliances simultaneously, but cannot run a central air conditioner or large workshop equipment. The 2100-watt peak gives it enough surge capacity to start compressors and induction motors without stalling. Because the unit weighs only 45.9 pounds and measures 20 by 12.1 by 16.7 inches, users can load it into a truck bed or carry it to a job site without mechanical assistance. The 0.9-gallon fuel tank and 9-hour runtime at 25% load mean a full tank covers a typical workday without refueling. At 54 decibels, it runs quieter than a lawnmower, making it suitable for residential neighborhoods and early-morning camping. | The Westinghouse iGen2200 is a portable inverter generator delivering 2,200 starting watts and 1,800 running watts. Weighing approximately 46 pounds, it features a 79 cc 4-stroke OHV engine, operates quietly at around 52 dBA, and offers up to 12 hours of runtime on a 1.2-gallon fuel tank. Its inverter technology ensures clean power suitable for sensitive electronics. |
