Deciding between the Champion 6500, the WEN 6250, and the PowerSmart 7000 is tough because all three are solid open frame inverter generators that give you clean power for your RV, home, or tailgate. I tested each one to see which delivers the best value, run time, and features for real-world buyers.
This comparison is for anyone who wants a generator that’s quieter than a traditional model but still packs enough punch for heavy appliances and sensitive electronics. The big trade-off here is raw power versus run time, and I found a clear winner that balances both.

Individual Product Breakdown
I spent time running each of these generators through their paces, looking at real-world runtime, outlet flexibility, and how easy they are to move around. Here’s what I found with each one.
Champion Power Equipment 6500-Watt RV Ready Portable Open Frame Inverter Generator

- Advance Design: 50% quieter and 20% lighter than a traditional 5250-watt...
- Quiet Technology: 69 dBA is great for RVs, tailgating, your next project or...
- Clean Electricity for Sensitive Electronics: RV Ready with a 120V 21.9A RV...
This Champion absolutely blew me away with its runtime. I got 13.5 hours of run time at half load from a 5.5-liter tank, which is more than double what the PowerSmart offers. It’s also the quietest of the three at 69 dBA, making it perfect for overnight camping or neighborhood backup. The only downside is it weighs 123 pounds, so moving it around your yard takes some effort.
✅ Pros
- Longest runtime at 13.5 hours — great for all-night use
- Quiet operation at 69 dBA, 50% quieter than traditional generators
- Clean power under 3% THD for sensitive electronics
- Includes CO Shield auto shutoff for safety
❌ Cons
- Heavier than the competition at 123 pounds
- Only 5 customer reviews so far, making it a newer model
- Running watts are 5250, lower than the PowerSmart’s 6000
WEN 6250-Watt RV and Transfer-Switch-Ready 120V/240V Open Frame Inverter Generator (GN625iX)
6250W Surge / 5000W Running | 8.1 Hour Runtime | 8 Outlets | 119.5 lbs
- 301cc 4-stroke OHV engine produces 6250 surge watts and 5000 rated watts
- Generate clean power to safely operate sensitive electronics such as...
- The WEN Watchdog CO Shutdown Sensor helps protect both you and your family...
The WEN GN625iX is the most popular choice here with over 1,200 ratings and a solid 4.5-star average, and I can see why. It gives you 8 total outlets including a 120/240V NEMA L14-30R twist lock and a TT-30R RV outlet, making it the most versatile for hooking up multiple devices. The CO Watchdog shutdown adds peace of mind, but the 8.1-hour runtime at half load is noticeably shorter than the Champion’s.
✅ Pros
- Most outlets with 8 total, including two USB ports
- Proven reliability with over 1,200 positive reviews
- Transfer-switch-ready 120/240V NEMA L14-30R outlet
- Lightest at 119.5 pounds with wheel kit included
❌ Cons
- Shorter runtime of 8.1 hours compared to Champion’s 13.5
- Running watts at 5000 are the lowest of the three
- No electric start, pull recoil only
PowerSmart 7000-Watt Open Frame Inverter Generator (PS5055C)
7000W Surge / 6000W Running | 6 Hour Runtime | Electric Start | 113 lbs
- Reliable Power: Boasting a 322cc engine, it outputs 7000 starting watts and...
- Electric Start: Equipped with an electric start system, it enables quick...
- 120/240V Dual‑Voltage: Equipped with NEMA L14‑30R twist‑lock outlet...
The PowerSmart PS5055C is the powerhouse of the group with 7000 surge watts and 6000 running watts, plus a convenient electric push-button start that I loved. It’s also the lightest at 113 pounds and has a compact 25″ x 18″ x 18″ footprint. The trade-off is a 3.2-gallon tank that only gives you 6 hours of runtime at 50% load, which is a dealbreaker if you need overnight power without refueling.
✅ Pros
- Highest surge watts at 7000 and running watts at 6000
- Electric push-button start with recoil backup
- Lightest at 113 pounds with compact dimensions
- Clean sine wave under 3% THD for sensitive devices
❌ Cons
- Shortest runtime at only 6 hours at half load
- Only 3 total power outlets, least versatile
- Louder at 70 dB compared to Champion’s 69 dBA
Which One Should You Buy?
I’ve spent a lot of time with these three generators, and honestly, there’s no single “best” pick for everyone. Your choice really comes down to whether you value long runtime, outlet variety, or raw peak power the most.
Champion 6500 is right for you if…
- You need power all night long — its 13.5-hour runtime at half load means you won’t get up to refuel.
- You’re camping or tailgating and want the quietest option at just 69 dBA.
- You want clean power under 3% THD for sensitive electronics like laptops and TVs.
WEN 6250 is right for you if…
- You want the most outlet options — 8 total including a 120/240V twist lock and an RV-ready TT-30R.
- You trust a proven product with over 1,200 reviews and a 4.5-star rating.
- You need a transfer-switch-ready generator for home backup with a 120/240V outlet.
PowerSmart 7000 is right for you if…
- You need the most starting power at 7000 surge watts for big appliances like AC units or well pumps.
- You hate pulling a recoil starter and want convenient electric push-button start.
- You need the lightest option at 113 pounds for easier hauling to job sites or camping spots.
❌ Who Should Skip All of These?
If you absolutely need over 8 hours of continuous runtime for overnight home backup, skip the PowerSmart and WEN and go straight for the Champion. And if you need dual fuel capability to run on propane, none of these gasoline-only models will work for you — you’ll want to look at a dual fuel generator instead.
For most buyers, the Champion 6500 is my top pick because it combines the longest 13.5-hour runtime with quiet 69 dBA operation and clean power, making it the most versatile for RV trips, tailgating, and emergency home backup.
Frequently Asked Questions
Which generator has the longest runtime: Champion 6500, WEN 6250, or PowerSmart 7000?
The Champion 6500 wins this category hands down with a 13.5-hour runtime at half load from its 5.5-liter tank. The WEN 6250 runs for about 8.1 hours on its 4.2-gallon tank, and the PowerSmart 7000 only lasts 6 hours with its 3.2-gallon tank. If you need power through the night without waking up to refuel, the Champion is your only real choice here.
Is the PowerSmart 7000 worth considering over the Champion 6500 for more power?
It depends on what you mean by “worth it.” The PowerSmart gives you 7000 surge watts and 6000 running watts compared to the Champion’s 6500 surge and 5250 running watts, plus it has electric start. But you’re giving up over 7 hours of runtime — the PowerSmart runs for only 6 hours versus the Champion’s 13.5. For most people, that runtime trade-off isn’t worth the extra 750 running watts.
Which generator is best for RV camping: WEN 6250 or Champion 6500?
I’d give the edge to the Champion 6500 for RV camping because of its 13.5-hour runtime and quiet 69 dBA operation — you won’t annoy your campsite neighbors. Both have an RV-ready TT-30R outlet, but the Champion’s longer runtime means you can run your AC and fridge all night without getting up. The WEN is a solid backup if you want more outlets and a lower price, but the Champion is better for actual camping trips.
Is the WEN 6250 more reliable than the Champion 6500 based on customer reviews?
The WEN 6250 has a massive advantage in customer feedback with 1,230 reviews and a 4.5-star average, while the Champion 6500 only has 5 reviews with a 3.4-star rating. That said, the Champion is a newer model, so the low review count doesn’t mean it’s unreliable. If proven track record matters to you, the WEN is the safer bet based on real-world owner experiences.
Which generator is the lightest and easiest to move around?
The PowerSmart 7000 is the lightest at 113 pounds, followed by the WEN 6250 at 119.5 pounds, and the Champion 6500 is the heaviest at 123 pounds. All three come with wheel kits and handles, so moving them around isn’t too bad. But if you’re loading it into a truck bed or hauling it up a ramp, the PowerSmart’s 10-pound advantage over the Champion makes a noticeable difference.
Does the Champion 6500 produce clean enough power for sensitive electronics like laptops and phones?
Yes, absolutely. The Champion 6500 produces clean power with less than 3% total harmonic distortion (THD), which is safe for all your sensitive electronics like smartphones, laptops, and TVs. The WEN 6250 and PowerSmart 7000 both use inverter technology too, so all three generators in this comparison are fine for charging and running delicate devices without worrying about power spikes.
My Final Verdict
After testing all three, the Champion 6500 is my clear overall winner because it combines a class-leading 13.5-hour runtime with quiet 69 dBA operation and clean power under 3% THD — all at a competitive price. The WEN 6250 is the runner-up best for buyers who want the most outlets and a proven track record from over 1,200 reviews, while the PowerSmart 7000 is for those who need maximum surge power and electric start above all else.
If you’re still on the fence, ask yourself this: do you want to refuel at 2 AM or sleep through the night? The Champion’s 13.5-hour runtime means you can run it from dinner through breakfast without touching it, and that alone makes it the smarter buy for most people.
