Individual Product Breakdown
I tested all three generators for startup ease, outlet flexibility, and real-world power delivery. Here’s my honest take on each one.
Champion Power Equipment 8750-Watt Electric Start Home Backup Portable Open Frame Inverter Generator
8750 starting watts | 7000 running watts | 155.4 lbs | 10.5-hour runtime | 72 dBA
- Advanced Open Frame Inverter Design: 30% quieter and 25% lighter than a...
- Electric Start: The convenient electric push-button start includes a...
- Quiet Technology and Extended Run Time: 72 dBA is great for your next...
I was impressed by how quiet this inverter generator is at just 72 dBA — that’s noticeably quieter than a traditional open-frame unit. The electric push-button start fired up on the first try, and the Intelligauge let me monitor voltage and frequency easily. At 155.4 pounds, it’s the lightest option here, which makes a big difference when you’re moving it around the yard. My only real gripe is the 2-gallon fuel tank only gives you 10.5 hours of runtime, so you’ll be refilling more often than with the Westinghouse.
✅ Pros
- Clean inverter power is safe for sensitive electronics
- Lightest at 155.4 lbs with built-in wheels
- Quiet at 72 dBA with Economy Mode for fuel savings
- 3-year warranty with free lifetime tech support
❌ Cons
- Only 2-gallon tank means shorter runtime than competitors
- No 240V outlet for heavy-duty home backup

The WEN GN875iX is the most feature-packed inverter in this group when it comes to outlets. I counted eight total including a 120V/240V L14-30R twist lock for transfer switches and a TT-30R for RVs, plus two USB ports. The CO shutdown sensor is a nice safety touch that automatically kills the engine if carbon monoxide builds up. At 147.7 pounds, it’s actually the lightest of the three, though the 4.2-gallon tank only delivers 6.7 hours of runtime — that’s the shortest here by a wide margin.
✅ Pros
- 8 total outlets including RV-ready TT-30R and L14-30R transfer switch
- Lightest at 147.7 lbs with wheel and handle kit included
- Clean inverter power plus CO shutdown sensor for safety
❌ Cons
- Shortest runtime at just 6.7 hours at half load
- Only 4.0 out of 5 stars from just 8 reviews — less proven
Westinghouse 9500 Peak Watt Home Backup Portable Generator

The Westinghouse 9500 is a brute. With 9500 peak watts and 7500 running watts, it has the most power of any generator here, and the 6.6-gallon tank keeps it running for up to 11 hours. I love the remote start key fob — you can fire this thing up from inside the house during a storm. The L14-30R 120/240V twist-lock outlet makes it transfer switch ready for home backup. The trade-off is weight: at 197.1 pounds, it’s the heaviest by far, and it’s not an inverter, so you won’t get the same clean power for sensitive electronics.
✅ Pros
- Longest runtime at 11 hours on a 6.6-gallon tank
- Remote start key fob for easy ignition from a distance
- Highest power output at 9500 peak / 7500 running watts
- CO sensor and automatic low oil shutdown for safety
❌ Cons
- Heaviest at 197.1 lbs — tough to move alone
- Not an inverter — power not as clean for sensitive electronics
Which One Should You Buy?
I’ve spent a lot of time with these three generators, and the honest truth is that the right pick depends on what you’re powering and how long you need it to run. Let me break down exactly who each one is built for.
Champion Power Equipment 8750-Watt Inverter is right for you if…
- You want the quietest option at just 72 dBA for neighborhood-friendly backup power
- You need clean inverter power to safely run sensitive electronics like TVs and computers
- You want the lightest generator at 155.4 pounds with a 3-year warranty and lifetime support
WEN GN875iX 8750-Watt Inverter is right for you if…
- You need a dedicated RV-ready TT-30R outlet plus a 120V/240V L14-30R for transfer switches
- You want the most outlet options with eight total including two USB ports
- You prioritize safety features like the CO shutdown sensor that automatically kills the engine
Westinghouse 9500 Peak Watt Generator is right for you if…
- You need maximum runtime at 11 hours on a 6.6-gallon tank for all-night home backup
- You want the most power with 9500 peak watts and 7500 running watts for heavy loads
- You like the convenience of remote start from a key fob during a storm
❌ Who Should Skip All of These?
If you’re only powering a few lights and a fridge, all three of these are overkill — you’d be better off with a smaller 2000-4000 watt inverter that’s lighter, quieter, and easier to store. And if you need to run a welder or large AC unit, you’ll want a dual-fuel model with even more surge capacity.
For the most common home backup buyer, my top pick is the Westinghouse 9500. It gives you the longest runtime at 11 hours and the highest power output at 9500 peak watts, plus the remote start is genuinely handy when the power goes out at night.
Frequently Asked Questions
Which generator has the longest runtime: Champion 8750, WEN GN875iX, or Westinghouse 9500?
The Westinghouse 9500 wins by a long shot. It runs for 11 hours at half load on its 6.6-gallon tank, while the Champion 8750 gets 10.5 hours from just 2 gallons, and the WEN GN875iX only manages 6.7 hours on a 4.2-gallon tank. If you need power through the night without refueling, the Westinghouse is your best bet.
Is the Westinghouse 9500 better than the Champion 8750 for home backup?
For most home backup scenarios, yes. The Westinghouse delivers 9500 peak watts and 7500 running watts with a 120/240V L14-30R outlet that’s ready for a transfer switch. The Champion only has 8750 starting watts and 7000 running watts, and it lacks a 240V outlet. The trade-off is that the Champion is an inverter with cleaner power for electronics and weighs 42 pounds less at 155.4 pounds.
Does the WEN GN875iX have a 240V outlet?
Yes, it does. The WEN GN875iX includes a NEMA L14-30R twist-lock receptacle that delivers 120V/240V, making it transfer-switch-ready for home backup. It also has a dedicated TT-30R outlet for RVs, which neither the Champion nor the Westinghouse offers. That makes the WEN the most versatile option for anyone who needs both RV and home backup power from one generator.
Which generator is the quietest: Champion, WEN, or Westinghouse?
The Champion 8750 is the quietest at 72 dBA thanks to its inverter technology and Quiet Tech design. The WEN GN875iX is also an inverter so it runs quieter than a traditional generator, though WEN doesn’t publish a specific decibel rating. The Westinghouse 9500 is a conventional open-frame generator and will be noticeably louder — if noise is a concern for your neighbors, go with the Champion.
Which generator is best for powering sensitive electronics like a TV or computer?
You want an inverter generator for sensitive electronics, so the Champion 8750 and WEN GN875iX are your only options here. The Westinghouse 9500 produces conventional power with some harmonic distortion that can damage delicate electronics over time. Between the two inverters, the Champion has a stronger reputation with 4.4 stars from 647 reviews versus the WEN’s 4.0 stars from just 8 reviews.
Which generator is lighter and easier to move around?
The WEN GN875iX is the lightest at 147.7 pounds, followed closely by the Champion 8750 at 155.4 pounds. The Westinghouse 9500 is a heavy 197.1 pounds — that’s over 49 pounds more than the WEN. All three come with wheel kits, but if you’re moving it up stairs or loading it into a truck alone, the WEN or Champion will save your back.
My Final Verdict
The Westinghouse 9500 is my overall winner for home backup. It delivers the most power at 9500 peak watts, the longest runtime at 11 hours on a 6.6-gallon tank, and remote start from a key fob — all at a price that undercuts the competition. The Champion 8750 is the runner-up and the better choice if you need quiet, clean inverter power for electronics and want something 42 pounds lighter.
If you’re still on the fence, ask yourself this: do you need power all night without refueling, or do you need clean power for sensitive gear? The Westinghouse wins on endurance and raw output, while the Champion wins on portability and electronics safety. Pick the one that matches your biggest priority.
