Our editorial team weighed Westinghouse Outdoor Power Equipment's published specifications and how it stacks up against similar products in the generators category. What stands out: Extremely Quiet at 52dBA, Lightweight & Compact, and 12-Hour Runtime at 25% Load. Where it falls short: Manual Recoil Start Only and Gasoline Only. That puts it at 8.1/10 on our WG Score – an excellent, well-rounded option.
Reviewed byEthanWhen choosing a generator for your camping trailer, the single most important specification is running watts. This continuous power output determines what appliances you can run simultaneously, from lights and refrigerators to air conditioners and microwaves. Without enough running watts, you risk overloading the unit and shutting down your power supply at the worst possible time. That is why our roundup focuses on models that deliver reliable, sustained wattage for your trailer needs.
For a deeper look at camp-specific power solutions, check out our guide on the best electric generators for camping.
Running Watts Explained
Running watts represent the steady power a generator can supply over hours of operation. This is different from starting (peak) watts, which are temporary surges needed to start motor-driven devices like air conditioning compressors. Most camping trailers have a mix of resistive loads (lights, heaters) and inductive loads (fridge compressors, furnace fans). You want a generator whose running watts exceed the total continuous draw of everything you plan to power.
Let us take a concrete example using the Westinghouse iGen2200 (ASIN B01MUP6L1U). It has 1,800 running watts and a 1.2-gallon fuel tank that offers up to 12 hours of runtime at 25% load (that is 450 watts). Now suppose your trailer uses a 600W microwave, a 300W TV, and a 200W laptop charger , totalling 1,100 watts. The iGen2200 can handle that comfortably with 700 watts of headroom. Even at this higher load, the 1.2-gallon tank would provide roughly 8 hours of runtime based on fuel consumption rates. This real-world calculation shows why focusing on running watts prevents power shortfalls during your trip.
Pros
- Extremely quiet at 52 dBA for community-friendly operation
- Lightweight and compact design with easy-carry handle
- Fuel-efficient with 12-hour runtime at 25% load
- Clean power ideal for sensitive electronics
- Parallel capable for scalable power needs
Cons
- Recoil start only requires manual pulling
- Gasoline-powered with no dual fuel option
- Runtime drops at full load needing more frequent refills
The Westinghouse iGen2200 is a compact portable inverter generator designed for campers, RVers, tailgaters, and homeowners seeking dependable backup power. With 2200 peak watts and 1800 running watts from its 80cc 4-stroke engine, it powers essentials like refrigerators, lights, and chargers during outages or off-grid adventures without overwhelming noise or bulk.
Standout features include ultra-quiet operation at 52 dBA, comparable to a normal conversation, thanks to its advanced active throttle that adjusts speed to match demand. This delivers up to 12 hours of runtime on a 1.2-gallon tank at 25% load while producing clean power under 3% THD, safely running laptops, TVs, and other electronics. Parallel capability lets users link two units for doubled output using a separate cord, and built-in safeguards like low oil shutdown add reliability.
Build quality shines in its lightweight 46 lb frame with a suitcase-style handle for easy transport, plus durable construction meeting EPA and CARB standards. The recoil start is straightforward, though it lacks electric start, and the two 120V outlets plus USB ports cover most needs efficiently.
Drawbacks include manual recoil starting and gasoline-only fuel, which may limit convenience compared to dual-fuel models, plus shorter runtime under heavy loads. Still, for its class, it excels in portability and efficiency.
Verdict: The iGen2200 earns high marks as a top pick for quiet, portable power. Buy it if you prioritize lightweight design, low noise, and clean energy for recreational or emergency use.

Best Generators For A Camping Trailer: Our Picks Against the Numbers
Most Powerful for Its Size: Westinghouse iGen2800
With 2,200 running watts from a 46.3-pound frame, the iGen2800 packs the highest running wattage among compact inverter models. This means you can run a 1500W RV air conditioner plus essentials without upgrading to a heavier open-frame unit. The tradeoff: its 0.98-gallon tank reduces runtime at full load compared to larger tanks, but the economy mode still delivers up to 12 hours at low loads.
Skip this if: you need more than 8 hours of continuous high-load runtime between refueling stops. A larger tank model may suit extended boondocking better.
View on Amazon.comBest Value for High Output: WEN 5600-Watt Portable Generator (GN5600)
With 4,500 running watts, this WEN model delivers nearly double the continuous power of compact inverters at a budget-friendly price. It is ideal for running multiple appliances like a large RV air conditioner, electric water heater, and microwave simultaneously. The 4.3-gallon tank provides up to 12.5 hours at half load, but note this is an open-frame conventional generator, so it is louder and heavier (about 120 lbs) than inverter units.
Skip this if: quiet operation or portability is your top priority. The iGen2800 is better for noise-sensitive campsites.
View on Amazon.comCleanest Power Output: WEN RV-Ready 4000-Watt Open Frame Inverter Generator
This inverter model produces 3,500 running watts with less than 3% total harmonic distortion, making it safe for sensitive electronics like laptops, tablets, and smart TVs. It is 30% lighter than a standard 4,000-watt generator, which helps when moving it around the campsite. The tradeoff: it cannot match the wattage of the GN5600 for heavy loads, and its 2-year warranty is shorter than some competitors.
Skip this if: you need to power a large air conditioner requiring over 3,500 running watts. The GN5600 is better for high-draw situations.

Other Things That Matter for Best Generators For A Camping Trailer
Noise Level and Campsite Regulations
Most campgrounds enforce quiet hours, so choose a model rated at 52-60 dBA if you plan to run it at night. Inverter generators are typically quieter than open-frame ones. For more details, read our guide on best portable power generators for camping.
Fuel Type and Runtime
Gasoline is the most common and accessible fuel, but dual-fuel models (gasoline/propane) offer flexibility. Tank size directly affects runtime: a 4.3-gallon tank can run up to 12.5 hours at half load, while a 1-gallon tank may only offer 6-8 hours under similar conditions. Plan your refueling stops accordingly.
Portability and Storage
Compact inverters like the Westinghouse iGen2800 weigh under 50 pounds and can be stored in small compartments. Larger open-frame generators may require a dedicated storage area and a wheel kit for mobility. Consider your vehicle’s space constraints before choosing.

Frequently Asked Questions
How many running watts do I need for a camping trailer?
Most camping trailers require at least 2,000 running watts to power basic items like lights, refrigerator, and furnace. If you also run a roof air conditioner or microwave, look for 3,500-4,500 running watts.
Are inverter generators worth the extra cost for camping trailers?
Yes, inverter generators provide cleaner power suitable for sensitive electronics and are significantly quieter than conventional models. They are often lighter and more efficient at partial loads.
Can I run an RV air conditioner with a generator under 3,000 watts?
It depends on the AC unit’s starting wattage. A 13,500 BTU AC typically needs 1,500-2,000 starting watts and 1,200-1,500 running watts. A 2,200-watt running inverter generator can handle it with additional loads, but check your AC’s specs.
Should I get a dual-fuel generator for camping?
Dual-fuel models offer flexibility with propane, which stores indefinitely and burns cleaner. However, they usually produce slightly less wattage on propane. For most campers, gasoline-only models are sufficient and often cheaper.
