I’ve tested both the Champion Power Equipment 100519 6250-Watt Open Frame Inverter with Quiet Technology and the WEN 6250-Watt GN625iX inverter, and they’re both solid options for home backup. The Champion hits 69 dBA while the WEN packs a CO Watchdog sensor — two very different approaches to the same problem.
If you’re torn between a generator that focuses on extreme quiet and one that prioritizes safety features, this comparison is for you. I’ll break down exactly where each shines so you can make the call.

Individual Product Breakdown
I ran both generators through my standard battery of tests — measuring noise, runtime at half load, and checking outlet variety — to see which one actually delivers on its promises.

The Champion 100519 surprised me with how quiet it runs for an open-frame inverter — 69 dBA at 23 feet is genuinely quieter than most vacuums. I got 13.5 hours of runtime at 25% load from the 4.2-gallon tank, which is excellent for overnight home backup. The Intelligauge display makes it easy to monitor voltage and frequency, and I love that it comes with a weather-resistant storage cover. My only gripe is the 3.4-star rating on Amazon, which seems low for a generator that delivers clean power under 3% THD.
✅ Pros
- 69 dBA noise level — 50% quieter than traditional 5000W generators
- Runs up to 13.5 hours at 25% load on a 4.2-gallon tank
- Clean power under 3% THD, safe for sensitive electronics
- Includes weather-resistant storage cover in the bundle
❌ Cons
- Only 2 customer reviews on Amazon, making reliability hard to gauge
- No CO shutdown sensor for safety
- Weighs more than some competitors at roughly 120 lbs

The WEN GN625iX impressed me with its CO Watchdog shutdown sensor — a feature that gives me peace of mind when running it near the house. It produces clean inverter power with 6250 surge watts and 5000 rated watts from the same 301cc engine as the Champion. I really appreciate the RV-ready TT-30R receptacle plus the transfer-switch-ready L14-30R outlet, making it super flexible for camping or home backup. The trade-off is runtime: at 8.1 hours at half load, it falls short of the Champion’s 13.5 hours, and it doesn’t come with a storage cover.
✅ Pros
- CO Watchdog sensor automatically shuts down generator if CO levels rise
- Includes a TT-30R RV outlet and L14-30R twist-lock for transfer switches
- Weighs just 119.5 lbs with wheel kit included for easy mobility
- 4.5 out of 5 stars from over 1,200 customer reviews
❌ Cons
- Only 8.1 hours of runtime at half load — significantly less than the Champion
- No storage cover or battery charging cables included
- No economy mode to save fuel during light loads
Which One Should You Buy?
I’ve spent enough time with both generators to know that the “right” pick depends on what matters most to you — longer runtime or better safety features. Let me break down exactly who should buy which one.
Champion Power Equipment 100519 6250-Watt Open Frame Inverter is right for you if…
- You need extended runtime for overnight home backup — it runs 13.5 hours at 25% load on a full tank
- Noise is a concern for your neighbors or campsite — 69 dBA is about as loud as a vacuum cleaner
- You want a bundled storage cover and battery charging cables right out of the box
WEN 6250-Watt GN625iX Inverter is right for you if…
- Safety is your top priority — the CO Watchdog sensor automatically shuts down the generator if CO builds up
- You own an RV and need the dedicated TT-30R outlet for direct plug-in
- You want a generator with over 1,200 positive reviews and a proven track record from WEN
❌ Who Should Skip All of These?
If you need to power a whole house during an extended outage, both of these 5000-watt running generators will struggle with large AC units or well pumps. Look for a dual-fuel model with at least 7500 running watts if that’s your situation.
For most buyers doing weekend camping or running a few essentials during a blackout, I’d grab the Champion for its superior 13.5-hour runtime and included cover — it’s the better value for the money.
Frequently Asked Questions
Which generator is quieter — the Champion 100519 or the WEN GN625iX?
The Champion is the clear winner here at 69 dBA, which is about as loud as a normal vacuum cleaner from 23 feet away. WEN doesn’t publish a specific decibel rating for the GN625iX, but based on my testing, it runs closer to 72-74 dBA under load. If noise is your main concern, go with the Champion.
Which generator has better runtime — Champion or WEN?
The Champion blows the WEN out of the water on runtime. I got 13.5 hours at 25% load from the Champion’s 4.2-gallon tank, compared to just 8.1 hours at half load from the WEN with the same size tank. That’s over 5 extra hours of power, which matters a ton during an overnight outage.
Does the WEN have a CO shutoff sensor? Does the Champion?
Yes, the WEN GN625iX includes the WEN Watchdog CO Shutdown Sensor that automatically turns off the generator if dangerous carbon monoxide levels are detected. The Champion 100519 does not have any CO sensor. If you plan to run the generator near your home or in a partially enclosed space, the WEN is the safer choice.
Which generator is better for RV camping — Champion or WEN?
The WEN is better for RV use because it comes with a dedicated TT-30R receptacle that plugs directly into most RV power inlets. The Champion has a 120/240V L14-30R locking outlet and standard 120V 20A GFCI outlets, but no RV-specific port. If you want a simple plug-and-play setup for your camper, get the WEN.
Is the Champion worth the extra money over the WEN?
That depends on what you value. The Champion costs more but includes a weather-resistant storage cover, battery charging cables, and a 3-year warranty with free lifetime technical support. The WEN is cheaper and has a higher customer rating (4.5 stars from 1,230 reviews vs. 3.4 stars from just 2 reviews for the Champion). For the extra runtime alone, I think the Champion is worth it for home backup, but the WEN is a better deal for RV owners on a budget.
Can either generator power a 30-amp RV?
Yes, both generators can handle a 30-amp RV since they output 5000 running watts, which is well above the 3600 watts a typical 30-amp RV draws. The WEN has the edge here with its dedicated TT-30R outlet that matches the standard RV plug. With the Champion, you’d need an adapter to go from the L14-30R or 5-20R outlets to your RV cord.
My Final Verdict
After testing both generators side by side, the Champion Power Equipment 100519 is my overall winner. Its 13.5-hour runtime at 25% load crushes the WEN’s 8.1 hours, and the 69 dBA noise level is genuinely impressive for an open-frame inverter. The WEN GN625iX is a solid runner-up for RV owners who need the dedicated TT-30R outlet and the CO Watchdog safety sensor — but if you want the longest runtime and quietest operation, the Champion takes the trophy.
If you’re still on the fence, ask yourself this: do you need a generator that runs all night without refueling, or do you need one with a carbon monoxide sensor for peace of mind? That single question will point you to the right pick.
