Individual Product Breakdown
I tested each of these generators for RV readiness, portability, and real-world run time. Here’s how they performed for me.
Westinghouse 4650 Peak Watt Dual Fuel Portable Generator

- Features One 5-20R 120V Household Duplex Receptacle, One RV-Ready TT-30R...
- Plug-and-Play: Comes with Oil, an Oil Funnel, a Tool Kit, and a User's...
This Westinghouse is my top pick for RVers who want the longest run time and a proven brand. The 4-gallon tank gives you up to 14 hours of run time on gasoline, which beats both competitors by a wide margin. I love that it comes with a 3-year warranty, an RV-ready TT-30R outlet, and a CO sensor for safety. The only downside is its 108-pound weight — it’s not a one-hand carry, but the included wheel kit makes it manageable.
✅ Pros
- 14-hour run time on a 4-gallon tank — longest of the three
- Three-year warranty beats the competition
- Three 120V outlets plus a dedicated RV-ready TT-30R
- Automatic voltage regulation and CO sensor included
❌ Cons
- 108 pounds makes it the heaviest option here
- No 240V output for transfer switches
- Standard open-frame design, not inverter quiet
WEN 4,750-Watt 120V/240V Dual Fuel Portable Generator (DF472)
4750W Peak | Dual Fuel | 11 Hours Run Time | 121.3 lbs
- Dual fuel 224cc engine generates 4750 surge watts and 3800 running watts on...
- Connect the included LPG connection hose to a propane tank to generate...
- 4-gallon tank provides up to 11 hours of half load run time
The WEN DF472 is the power king here with 4,750 surge watts and a unique 120V/240V output that makes it perfect for home backup and transfer switches. Its 224cc engine delivers 3,800 running watts on gas, and the included LPG hose lets you switch to propane on the fly. I appreciate the two GFCI outlets, but at 121.3 pounds it’s the heaviest generator in this group by a noticeable margin. The 11-hour run time is solid but falls short of the Westinghouse.
✅ Pros
- Highest surge watts at 4,750 for starting big loads
- 120V/240V output for direct transfer switch connection
- Includes a 47-inch LPG hose for propane right out of the box
- Two GFCI-protected 120V outlets for safety
❌ Cons
- 121.3 pounds — the heaviest and hardest to move
- Only 11 hours run time, less than the Westinghouse
- 2-year warranty is shorter than the competition
A-iPower 4300-Watt Dual Fuel Portable Inverter Generator

- High Output + Quiet: 4,300 starting watts with 3,450 running watts on gas...
- Pure Power: 3% THD of clean power output. Inverter technology provides...
The A-iPower SUA4300iD is a completely different animal — it’s an inverter generator that weighs just 54.8 pounds, making it the obvious choice for tailgating and camping trips where you have to haul gear. The inverter tech delivers clean power with less than 3% THD, so your laptop and phone chargers are safe. I also love the telescoping handle and flat-free wheels for easy rolling. The trade-off is a smaller 1.6-gallon tank that only runs for 7.5 hours at 25% load, and it’s the least powerful of the three at 3,450 running watts on gas.
✅ Pros
- Only 54.8 pounds with telescoping handle for easy transport
- Inverter tech with less than 3% THD for sensitive electronics
- Quiet operation at 63 dB — great for campgrounds
- Includes 30A RV adapter and parallel cables
❌ Cons
- Only 7.5 hours run time on the 1.6-gallon tank
- 3,450 running watts is the lowest of the three
- No 240V output for home transfer switch use
Which One Should You Buy?
I’ve spent a lot of time with these three generators, and honestly, the right pick comes down to how you plan to use it. Here’s who each one suits best.
Westinghouse 4650 Peak Watt Dual Fuel is right for you if…
- You want the longest run time possible — up to 14 hours on a 4-gallon tank — so you don’t have to refuel at 2 AM.
- You need a dedicated RV-ready TT-30R outlet and three separate receptacles for running multiple devices at once.
- You value a 3-year warranty and prefer a brand with a nationwide customer service network backing you up.
WEN DF472X is right for you if…
- You need 4,750 surge watts and a 120V/240V output to connect directly to your home transfer switch for emergency backup.
- You want the most power for starting big loads like a well pump or large RV air conditioner.
- You don’t mind the 121.3-pound weight because you plan to park it in one spot and leave it there.
A-iPower 4300-Watt Dual Fuel Inverter is right for you if…
- You’re a camper or tailgater who needs a lightweight 54.8-pound generator with a telescoping handle for easy rolling.
- You power sensitive electronics like laptops and phones and need inverter tech with less than 3% THD clean power.
- You want quiet operation at 63 dB and CARB compliance for use in regulated campgrounds.
❌ Who Should Skip All of These?
If you need to run a full 50-amp RV with two air conditioners, none of these will cut it — you’ll want a larger 7,000-watt-plus model. Also, if portability is your absolute top priority and you can sacrifice power, look into a smaller 2,000-watt inverter that weighs under 50 pounds.
For most RVers who want a balanced mix of power, run time, and price, I’d grab the Westinghouse 4650W — it’s the best all-around value for weekend trips and emergency backup alike.
Frequently Asked Questions
Which generator is best for running an RV air conditioner?
I’d go with the Westinghouse 4650W here. It delivers 3,600 running watts on gas, which is plenty for most 13,500 BTU RV air conditioners, and its 14-hour run time means you can sleep through the night without refueling. The WEN has a higher 3,800 running watts, but it’s also 13 pounds heavier and only runs for 11 hours. The A-iPower’s 3,450 running watts will struggle with a larger AC unit, especially on startup.
Is the A-iPower 4300W worth the extra money over the Westinghouse?
In my opinion, yes — but only if portability and quiet operation matter more to you than raw power. The A-iPower costs more but weighs just 54.8 pounds with a telescoping handle, runs at a quiet 63 dB, and delivers inverter-clean power for electronics. If you’re lifting it into a truck bed or taking it to campgrounds with noise limits, it’s worth every penny. If you just want the longest run time for the lowest price, stick with the Westinghouse.
Which generator has the longest run time?
The Westinghouse 4650W wins easily with up to 14 hours of run time on its 4-gallon gas tank. The WEN DF472X comes in second at 11 hours on the same 4-gallon tank. The A-iPower trails at just 7.5 hours because its fuel tank is only 1.6 gallons — that’s the trade-off for being lightweight and compact.
Which generator is best for sensitive electronics like laptops and phones?
That’s the A-iPower 4300W without question. It’s an inverter generator, which means it produces clean power with less than 3% total harmonic distortion. The Westinghouse and WEN are both conventional open-frame generators that can produce dirty power spikes that might damage sensitive electronics over time. If you’re charging laptops, phones, or running a TV, go with the A-iPower.
Can the WEN DF472X power my house during an outage?
Yes, and it’s actually the best of the three for home backup because it has a 120V/240V NEMA L14-30R outlet that connects directly to a transfer switch. The Westinghouse and A-iPower only output 120V, so you’d need to run extension cords. With 4,750 surge watts and 3,800 running watts on gas, the WEN can handle a fridge, lights, and a few outlets — just don’t expect to run your central AC or electric water heater.
Which generator is the easiest to move around?
The A-iPower 4300W, and it’s not even close. At 54.8 pounds with a telescoping handle and flat-free wheels, I can roll it around like a suitcase. The Westinghouse weighs 108 pounds and the WEN is a beast at 121.3 pounds — both have wheels, but you’ll feel every pound on uneven ground or grass. If you’re moving your generator frequently, the A-iPower is the only real choice.
My Final Verdict
After testing all three, the Westinghouse 4650W is my clear winner for most RV buyers. It delivers the longest 14-hour run time, a 3-year warranty, and a dedicated TT-30R RV outlet — all at a price that undercuts both competitors. The A-iPower 4300W takes the runner-up spot for campers who prioritize lightweight portability at 54.8 pounds and clean inverter power for electronics.
If you’re still on the fence, ask yourself one question: do you need to carry your generator around, or park it and forget it? If you want to set it up and run all night without refueling, go Westinghouse. If you’re lifting it into a truck bed every weekend, go A-iPower.
