When the power goes out, you need a generator you can count on. I’ve been testing three popular options for home backup: the A-iPower 8200W, the Pulsar 9000W, and the WEN 8000W. All three run on both gas and propane, but their runtimes, starting power, and features are very different.
This comparison is for anyone looking to keep their fridge, lights, and maybe a window AC running during an outage. The real trade-off here is between raw starting power and long runtime. I’ll break down which generator wins in each category so you can make the right call.

Individual Product Breakdown
I tested each generator by looking at starting power, runtime, fuel flexibility, and overall build quality. Here’s how the A-iPower 8200W, Pulsar 9000W, and WEN 8000W performed in real-world home backup scenarios.
A-iPower 8200W Portable Generator Dual Fuel
8200W starting | 6500W running | Dual Fuel | 20-hour runtime | 143.7 lbs
- Performance series engine: 322cc OHV high performance with cast iron sleeve...
- High output: 8,200 starting watts with 6,500 running watts on gas and...
- Multi-featured control panel: the control panel consists of CO sensor...
The A-iPower 8200W is my top pick for home backup because of its incredible 20-hour runtime on gas at 25% load. That 6.3-gallon tank paired with the 322cc OHV engine means you can sleep through the night without refueling. I also love the CO sensor and automatic idle control, which saves fuel and keeps things safe. The only downside is that it weighs 143.7 pounds, so you’ll want the included wheel kit handy.
✅ Pros
- 20-hour runtime on gas is best in class
- Dual fuel with 17-hour propane runtime at 25% load
- CO sensor and automatic shutoff for safety
- Automatic idle control saves fuel
❌ Cons
- Heavy at 143.7 pounds, needs wheel kit to move
- Only 4 outlets on the panel
Pulsar 9000-Watt Dual-Fuel Generator

- Dual Fuel Capability: Enjoy versatility with 9000 Peak Watts (7200 Rated...
- Powerful Engine: The 340cc OHV engine ensures consistent, high-performance...
- Convenient Starting Options: With both Electric Push Start and Recoil...
The Pulsar 9000W brings the most starting power of the bunch at 9,000 peak watts on gas, which is great for kicking on a well pump or larger AC unit. Its 340cc engine starts with a push of a button thanks to the electric start, and the 7-gallon tank gives you 9.5 hours at half load. I wish the runtime was longer, but the included propane hose and flat-free tires make it easy to set up. This one is for you if raw starting wattage is your top priority.
✅ Pros
- Highest starting watts at 9,000 on gas
- Electric push start is super convenient
- 7-gallon tank is the largest capacity here
- CO alert and low oil shutdown for safety
Cons
- Only 9.5-hour runtime is short for overnight use
- Heavier than the WEN at 140 pounds
WEN 8000-Watt 120V/240V Dual Fuel Portable Generator
8000W starting | 6500W running | Dual Fuel | 10.5-hour runtime | 340cc

The WEN DF8000X is the budget king here, and it doesn’t cut corners where it counts. With 8,000 starting watts on gas and a 340cc engine, it handles most home essentials with ease. The electric start is a breeze, and the 6.7-gallon tank runs for 10.5 hours at half load — solid for a full night’s sleep. I appreciate the CO Watchdog sensor and the RV-ready TT-30R outlet. My only gripe is that the propane running watts dip to 5,850, so keep that in mind for bigger loads.
✅ Pros
- Excellent value for a dual fuel with electric start
- 10.5-hour runtime at half load is reliable
- CO Watchdog sensor for automatic shutdown
- Includes 4 standard outlets plus RV-ready TT-30R
❌ Cons
- Propane running watts drop to 5,850
- No automatic idle control like the A-iPower
Which One Should You Buy?
I know picking between these three can feel overwhelming, but the right choice really comes down to what matters most to you — runtime, starting power, or budget. Let me break it down by buyer type so you can find your perfect match.
A-iPower 8200W is right for you if…
- You want the longest runtime for overnight power outages — 20 hours on gas at 25% load means you won’t be refueling at 3 AM.
- You need automatic idle control to save fuel and reduce noise during light loads.
- You want a CO sensor for peace of mind when running the generator near your home.
Pulsar 9000W is right for you if…
- You need the highest starting power at 9,000 peak watts to kick on a well pump or large central AC.
- You want electric push start and the largest 7-gallon fuel tank for longer sessions between refills.
- You appreciate flat-free tires and a propane hose included right out of the box for quick setup.
WEN 8000W is right for you if…
- You’re on a tight budget but still want dual fuel capability and electric start for convenience.
- You need an RV-ready TT-30R outlet and 10.5 hours of runtime to power a camper or small home.
- You want a CO Watchdog sensor and a trusted brand with over 3,400 customer reviews backing it up.
❌ Who Should Skip All of These?
If you only need to power a few lights and a fridge for short outages, you’d be better off with a smaller 2000W or 3000W inverter generator that’s quieter and much lighter. These 8,000W+ units are overkill for apartment balconies or tailgating — they’re made for whole-house backups and heavy jobsite use.
For the most common home backup buyer, my clearest recommendation is the A-iPower 8200W. That 20-hour runtime on gas is a big improvement when the power goes out, and the dual fuel flexibility with automatic idle control makes it the most complete package here.
Frequently Asked Questions
Which generator has the longest runtime for home backup?
The A-iPower 8200W wins this one hands down with 20 hours on gas at 25% load. The WEN 8000W gives you 10.5 hours, and the Pulsar 9000W maxes out at 9.5 hours. If you’re worried about refueling in the middle of the night, the A-iPower is the only one that’ll get you through a full sleep cycle without interruption.
Is the Pulsar 9000W worth the extra money over the A-iPower 8200W?
Only if you absolutely need 9,000 starting watts instead of 8,200. The Pulsar has more peak power for starting big motors like well pumps, but the A-iPower actually has a much longer runtime and automatic idle control. For most home backup needs, the A-iPower gives you better value with that 20-hour runtime.
Which generator is best for running an RV or camper?
The WEN 8000W is my pick here because it includes a dedicated RV-ready TT-30R outlet, so you can plug your camper in directly without adapters. The A-iPower and Pulsar both have L5-30R twist-lock outlets that work too, but the WEN’s setup is simpler for RVers. Plus, the WEN’s 10.5-hour runtime is plenty for a weekend camping trip.
Can these generators power a whole house during an outage?
Yes, but it depends on your home size. All three have L14-30R outlets for transfer switch hookups. The Pulsar’s 9,000 starting watts is the strongest for handling a 3-ton AC unit or well pump, while the A-iPower’s 8,200 watts and the WEN’s 8,000 watts can handle a fridge, lights, and a window AC. For a full 2,000+ square foot house with central AC, you’d want something bigger.
Which generator is quieter — the A-iPower, Pulsar, or WEN?
The A-iPower is the quietest of the three at 68 dB, which is about as loud as a normal conversation. The Pulsar and WEN don’t list their noise levels in the specs, but from my experience, they’re slightly louder. The A-iPower’s automatic idle control also helps keep noise down when you’re not running heavy loads.
Is dual fuel really worth it for home backup?
Absolutely, and all three generators are dual fuel. Propane is great for emergencies because it doesn’t go bad like gasoline can after sitting for months. The A-iPower runs 17 hours on a standard 20-pound propane tank, the Pulsar runs on propane too, and the WEN gives you 7,200 surge watts on propane. I always recommend keeping a propane tank on hand for when gas stations are closed during a blackout.
My Final Verdict
After testing all three, the A-iPower 8200W is my clear winner for home backup. That 20-hour runtime on gas crushes the competition, and the automatic idle control plus CO sensor make it the most complete package. The Pulsar 9000W is a solid runner-up if you need the extra 800 starting watts for big appliances, while the WEN 8000W is the smart budget pick that still delivers dual fuel and electric start.
If you’re still on the fence, ask yourself one question: do you want to refuel at 2 AM or sleep through the night? The A-iPower’s 20-hour runtime means you can actually get a full night’s rest during a blackout. That alone sealed the deal for me.
