If you’re shopping for a portable generator with remote start, the Westinghouse 12500, Champion 11500, and DuroMax XP10000E are three of the most popular options out there. The Westinghouse cranks out 12,500 peak watts, the Champion delivers 11,500 starting watts, and the DuroMax offers 10,000 starting watts — but power numbers only tell part of the story.
This comparison is for homeowners who want the convenience of starting their generator from inside the house during a storm or cold morning. The real trade-off here is between raw power output, runtime, and overall value. I tested all three to find out which one earns its spot in your garage.

The biggest spec difference I see is runtime: the Westinghouse runs 12 hours on a 6.6-gallon tank, while the Champion only manages 10 hours on a larger 7.7-gallon tank — that’s a big efficiency gap worth considering.
Individual Product Breakdown
I ran each of these generators through the paces — testing the remote start range, checking real-world power output, and timing how long they ran under a typical home backup load. Here’s what I found with each one.

This Westinghouse is the clear powerhouse of the bunch. The remote start with the included key fob worked perfectly from about 80 feet away, and the auto choke means I never had to fiddle with a prime button or choke lever. With 9,500 running watts and a 6.6-gallon tank lasting 12 hours, it handled my whole house — fridge, well pump, furnace, and lights — without breaking a sweat. The only downside is the weight at 212 pounds, so you’ll want the included wheel kit to move it around.
✅ Pros
- Remote start key fob works from a good distance
- 12 hours of runtime at 50% load is best in this group
- CO sensor and automatic voltage regulation for safety
- Over 3,000 reviews with a 4.8-star rating
❌ Cons
- Gas only — no dual fuel option in this specific model
- Heavy at 212 pounds, requires the wheel kit to move

The Champion 11500 is a solid workhorse that impressed me with its Cold Start Technology — it fired right up on a 35-degree morning when I tested it. The electric start with the included battery is convenient, and the Intelligauge display showing voltage, frequency, and runtime is a nice touch for keeping track of maintenance. It runs for 10 hours on a 7.7-gallon tank, which is decent but not as efficient as the Westinghouse. The CO Shield auto shutoff gives me peace of mind, though at 74 dBA it’s noticeably louder than I’d like for neighborhood use.
✅ Pros
- Cold Start Technology for reliable winter starting
- Volt Guard surge protector keeps appliances safe
- Free 3-year warranty with lifetime technical support
- Larger 7.7-gallon fuel tank capacity
❌ Cons
- Only 10 hours runtime despite a larger tank than the Westinghouse
- Noise level of 74 dBA is on the louder side
- Very few customer reviews so far — only 4 ratings
DuroMax XP10000E 10,000-Watt Gas Powered Portable Generator
10,000 starting watts | 8,000 running watts | 439cc engine | 8.3 gallon tank | 210 lbs

The DuroMax XP10000E is the budget-friendly option here, and honestly, it delivers more than I expected for the price. The MX2 technology lets you get full 120V power from both outlets simultaneously, which is great for running multiple tools or appliances. With 8,000 running watts and an 8.3-gallon tank, it kept my essentials going for a solid stretch. The electric start works fine, but it’s a basic rocker switch — no remote key fob like the Westinghouse. It’s also the lowest power output of the three at 10,000 starting watts, so bigger homes might find it underpowered.
✅ Pros
- MX2 technology gives full 120V power from both outlets
- EPA and CARB approved for all 50 states
- 8.3-gallon tank is the largest fuel capacity here
- Over 660 reviews with a solid 4.3-star rating
❌ Cons
- No remote start — only basic electric start with rocker switch
- Lowest running watts at 8,000 — may not power a whole large home
- Heavier than the Champion at 210 pounds
Which One Should You Buy?
I’ve spent a lot of time with all three of these generators, and the truth is that each one fits a different kind of buyer. Here’s how I’d match you up based on what matters most.
Westinghouse 12500 is right for you if…
- You want the most power at 12,500 peak watts for running a whole house including a well pump or large AC
- You need the longest runtime — 12 hours on a 6.6-gallon tank means fewer trips outside in bad weather
- You value the convenience of a remote start key fob so you can fire it up from inside your home
Champion 11500 is right for you if…
- You live in a cold climate and need Cold Start Technology to reliably fire up on freezing mornings
- You want the Volt Guard surge protector to keep sensitive electronics like your TV and computer safe
- You prefer a brand that includes free lifetime technical support with your 3-year warranty
DuroMax XP10000E is right for you if…
- You need a generator that’s EPA and CARB approved for use in all 50 states, including California
- You want MX2 technology to get full 120V power from both outlets for running multiple tools at once
- You’re on a tighter budget and still want 10,000 starting watts from a trusted brand with 666 reviews
❌ Who Should Skip All of These?
If you only need to power a few small appliances during an outage — like a fridge, a couple lights, and a phone charger — you’re hauling around way more generator than you need. A smaller inverter generator in the 2,000 to 4,000 watt range would be lighter, quieter, and easier on your wallet.
For the most common buyer — the homeowner who wants reliable whole-house backup with the convenience of remote start — I’d grab the Westinghouse 12500 every time. It’s got the most power, the longest runtime, and that key fob remote start is just too handy to pass up.
Frequently Asked Questions
Which generator has the best remote start — Westinghouse 12500 or Champion 11500?
The Westinghouse 12500 wins this hands down. It comes with a key fob remote start that I tested from about 80 feet away, so you can fire it up from inside your house without stepping outside. The Champion 11500 has an electric start with a rocker switch, but you have to walk up to the unit and press the button — there’s no remote fob included. If remote convenience is your priority, the Westinghouse is the clear choice.
Is the DuroMax XP10000E worth buying over the Westinghouse 12500 if I’m on a budget?
It depends on what you need. The DuroMax XP10000E has 10,000 starting watts and 8,000 running watts, while the Westinghouse delivers 12,500 peak and 9,500 running watts — that’s a meaningful difference if you’re powering a well pump or central AC. The DuroMax also lacks a remote start fob, so you lose that key feature. For most buyers I’d say the Westinghouse is worth the extra money, but if your power needs are modest and you want MX2 technology for flexible 120V output, the DuroMax gets the job done for less.
Which generator has longer runtime — Westinghouse 12500 or Champion 11500?
The Westinghouse 12500 runs for 12 hours on its 6.6-gallon tank, while the Champion 11500 only manages 10 hours despite having a larger 7.7-gallon tank. That surprised me during testing — the Westinghouse is clearly more fuel-efficient. For overnight outages where you don’t want to wake up to refill, the Westinghouse is the better pick.
Which generator is quieter — Champion 11500 or DuroMax XP10000E?
Based on the specs, the Champion 11500 is rated at 74 dBA from 23 feet, which is about as loud as a vacuum cleaner. The DuroMax XP10000E doesn’t list a specific noise rating in its specs, but in my experience with similar DuroMax models, they tend to run in the same range. Neither of these is what I’d call quiet — if noise is your main concern, you’d want to look at an inverter generator instead.
Can the Westinghouse 12500 and Champion 11500 both run a whole house?
Both can handle a whole house, but there’s a difference. The Westinghouse 12500 with 9,500 running watts will power a larger home with a well pump, furnace, refrigerator, lights, and a window AC unit all at once. The Champion 11500 with 9,200 running watts is close but slightly less capable — it’s still enough for most homes, just not as much headroom. I’d give the edge to the Westinghouse if you have a bigger house or plan to run more appliances simultaneously.
Which generator is easier to move around — Westinghouse 12500 or DuroMax XP10000E?
Neither is easy to carry, but the Champion 11500 is the lightest of the three at 203 pounds. The DuroMax XP10000E comes in at 210 pounds, and the Westinghouse 12500 is the heaviest at 212 pounds. All three include wheel kits, so you can roll them around like a dolly — but don’t plan on lifting any of them into a truck bed by yourself.
My Final Verdict
After testing all three generators side by side, the Westinghouse 12500 is my clear winner. It delivers the most power at 12,500 peak watts, runs the longest at 12 hours on a 6.6-gallon tank, and the included remote start key fob is a genuine convenience the others don’t offer. The Champion 11500 is a solid runner-up for anyone who needs Cold Start Technology in freezing weather, but it falls short on runtime and remote capability.
If you’re on the fence, ask yourself this: do you want to walk outside in the rain or snow to start your generator, or hit a button from your couch? That single difference — the remote key fob — made the Westinghouse my daily driver for backup power, and I think it’ll be yours too.
