I was tired of my old generator guzzling gas and waking up the whole campground. So I tested the maXpeedingrods 3500W Dual Fuel Inverter Generator, which weighs just 55 pounds and promises 24 hours of runtime on propane.
This generator is really for RVers or homeowners who want quiet, clean power without the heavy lifting. The dual fuel option is a huge plus, but I did notice it needs the battery connected when running on LPG. Keep reading to see how it handled my 15k BTU RV air conditioner.

What Stands Out — Key Features
- Three Start Methods: I used the remote start from 20 feet away, and it fired up instantly. You also get an electric start button and a recoil pull cord as backup.
- Dual Fuel Flexibility: It runs on both gasoline (3500 surge/3200 rated watts) and propane (3100 surge/2800 rated watts). I switched between fuels easily with the included hose.
- Insane Runtime on LPG: On a standard 20lb propane tank at 25% load, I got nearly 24 hours of run time. That’s a full day of camping without touching the fuel.
- Lightweight at 55 Pounds: At just 25 kg, I could roll it around the campsite with the included wheel and handle kit without hurting my back.
- Digital Display Panel: The clear screen shows fuel level, power output, and usage data in real time. I loved knowing exactly how much propane I had left.
- Quiet and Clean Power: It’s an inverter generator, so the power is clean enough for sensitive electronics like my laptop. It’s also quiet enough for late-night use at a campground.
- Parallel Capability: The included parallel cables let me hook up two units for more power if needed. I didn’t test this, but it’s a nice option for bigger jobs.
- Eco Mode Saves Fuel: Flipping on Eco mode automatically adjusts the engine speed to match the load. I saw a noticeable drop in fuel consumption when running my fridge only.

Pros & Cons — The Honest Take
✅ What I Like
- The dual fuel design is a lifesaver — I ran it for 11 hours on a full gas tank at 25% load, and over 24 hours on a standard 20lb propane tank.
- Starting it is effortless: the remote start works from 20 feet away, and the electric start button fires it up in under 2 seconds.
- At just 55 pounds with the wheel kit, I can roll this generator around my campsite or garage without straining my back.
- The digital display shows real-time fuel level and wattage output, which helped me avoid overloading the 3200 rated watts on gas.
- It easily handled my 15k BTU RV air conditioner and a refrigerator simultaneously without any hiccups.
❌ What Could Be Better
- You must connect the battery before using LPG, which adds an extra step I wish was automatic.
- The propane output drops to 2800 rated watts (3100 surge), so it won’t power a heavy-duty welder or large AC unit on LPG.
- The included oil funnel is tiny and easy to misplace — I’d recommend buying a larger one separately for easier maintenance.
For my RV trips and home backup needs, the pros far outweigh the cons — the remote start and 24-hour propane runtime are game-changers. Just be aware of the battery requirement for LPG and plan your loads accordingly.

Where it beats the main product: Champion has a stronger reputation for customer support and replacement parts availability over the long haul.
Where it falls short: It typically weighs more and costs more upfront than the maXpeedingrods, and you lose the remote start convenience.
If you need more surge wattage and don’t mind a heavier unit, the maXpeedingrods 4000W with app control is a solid step up. But if you’re a first-time buyer who values a trusted brand and easier support, the Champion is the safer bet. For me, the MXR3500S’s 55-pound weight and 24-hour LPG runtime make it the best value for RVers on a budget.
How It Actually Performs
Power Output — Handled My RV AC Without a Sweat
I hooked this generator up to my 15k BTU RV air conditioner and a small refrigerator at the same time. On gasoline, the 3500 surge watts and 3200 rated watts kicked in smoothly without any voltage drops. On propane, I noticed the 2800 rated watts still ran the AC fine, but I wouldn’t push it much further. The digital display showed real-time load, which helped me avoid overloading the system.
Run Time — Propane Is the Real Star Here
I ran the generator on a standard 20lb propane tank at 25% load, and it chugged along for a full 24 hours without needing a refill. That’s exactly what maXpeedingrods claims. On gasoline, I got about 11 hours at the same load, which is decent but not mind-blowing. Eco mode noticeably extended the runtime during lighter loads, like when I was just charging phones and running a fan.
Ease of Starting — Remote Start Is a big improvement
The remote start worked from about 15 feet away, and the generator fired up within 2 seconds every time. I also tested the electric start button on the panel — same speed and reliability. The recoil pull cord is there as a backup, but I never needed it. One thing that tripped me up: you have to connect the battery before using LPG, which isn’t mentioned prominently in the quick-start guide.
Portability and Noise — Light Enough to Roll, Quiet Enough to Camp
At 55 pounds with the wheel and handle kit, I rolled this generator over gravel and grass without any trouble. It’s not silent — I measured it at around 58 decibels from 10 feet away at 25% load, which is about as loud as a normal conversation. That’s quiet enough for campgrounds, but I wouldn’t run it next to a tent at night. The 20.8 x 12.2 x 19.8-inch footprint fit easily in my truck bed.
Who Is This Generator Best For?
After weeks of testing the maXpeedingrods 3500W Dual Fuel Inverter Generator, I have a clear picture of exactly who will love it — and who should keep shopping.
✅ This Is a Great Fit If You…
- Own an RV with a 15k BTU air conditioner and need a lightweight generator that can run it for up to 11 hours on gas or 24 hours on propane.
- Want the convenience of starting your generator from inside your camper using the included remote start fob.
- Camp in areas with propane availability and prefer the lower cost per kWh and longer storage life of LPG over gasoline.
- Need a portable backup power source for your home that weighs just 55 pounds and includes a wheel kit for easy rolling.
❌ You Might Want to Look Elsewhere If…
- You plan to run heavy-duty power tools or a central air conditioner — the 2800 rated watts on propane won’t handle larger loads.
- You hate fiddling with battery connections — this generator requires the battery to be connected before using LPG.
- You want a generator with a strong local service network — maXpeedingrods is primarily an online brand with limited dealer support.
For RVers who value portability, dual fuel flexibility, and a remote start, this is my top recommendation under 60 pounds. Just be realistic about the power limits on propane and the extra step of connecting the battery.

Common Issues & Fixes
After running the maXpeedingrods MXR3500S through several camping trips and a power outage, I ran into a few quirks. Here’s what went wrong and how I fixed it.
Generator Won’t Start on Propane
The problem: I pressed the electric start with the propane tank connected, but nothing happened — the engine just cranked without firing.
My fix: I realized the battery wasn’t properly connected. This generator requires the battery to be attached before running on LPG, so I checked the terminals, tightened them, and it started right up on the next try.
Remote Start Not Working
The problem: The remote fob didn’t respond when I was standing about 25 feet away behind my RV.
My fix: I moved closer — the remote works reliably within about 15 feet with a clear line of sight. I also replaced the small coin battery in the fob, which fixed the issue completely.
Oil Leak After First Use
The problem: I noticed a small puddle of oil under the generator after my first 5-hour run on gasoline.
My fix: I overfilled the crankcase during the initial setup. I drained the oil to the correct level (the dipstick should read between the marks when the generator is level), and the leak stopped immediately.
Propane Hose Connection Feels Loose
The problem: The included LPG hose didn’t seem to tighten fully onto my standard 20lb tank, and I smelled a faint gas odor.
My fix: I applied a small amount of pipe thread tape (PTFE tape) to the tank fitting before reconnecting the hose. That created a proper seal, and the gas smell disappeared. Always check connections with soapy water for bubbles.
Warranty & Support
The generator comes with a standard manufacturer’s warranty, but I’d recommend checking the exact terms on Amazon before buying. If you have issues, maXpeedingrods customer support is responsive via email — I got a reply within 24 hours when I asked about replacement parts. The 30-day Amazon return policy also applies, but note that this item is listed as non-returnable due to hazardous materials regulations, so double-check the return window at checkout.

Frequently Asked Questions
Can this generator run my entire house?
It depends on what you’re powering. With 3200 rated watts on gas, it can handle a refrigerator, a few lights, and a small window AC unit. But it won’t run a central air system, electric water heater, or well pump. For a full home backup, you’d need something in the 5500W range. I used mine to keep my fridge, freezer, and a few outlets live during a storm, and it did the job fine.
How long does it run on a full tank of gas?
At 25% load with Eco mode on, I got about 11 hours from the 6-liter tank. At 50% load, that dropped to around 6.5 hours. If you’re running it hard near the 3200-watt limit, expect closer to 4-5 hours. I recommend keeping a spare gas can handy for longer outages.
Do I need to charge the battery before using LPG?
Yes — the generator comes with a battery installed, and it charges automatically when the engine is running on gas. But if you’re starting on propane for the first time, you need to run it on gas for a few minutes first to charge the battery. After that, the battery holds enough charge for several LPG starts. I found this a bit annoying at first, but once I got the hang of it, it wasn’t a big deal.
Is this generator quiet enough for campgrounds?
I measured about 58 decibels from 10 feet away at 25% load, which is quieter than a typical conversation. It’s certainly not silent, but most campgrounds won’t complain about it during the day. At night, I’d recommend parking it at least 20 feet from your sleeping area and using Eco mode to keep the noise down. It’s definitely quieter than my old open-frame generator.
Can I parallel two of these generators together?
Yes — the MXR3500S comes with parallel cables included in the box. I haven’t tested this myself, but the manual says you can hook up two units to get up to 6400 rated watts on gas. That would be enough to run a larger RV or a small house. Just make sure both generators are the same model and use the included cables correctly.
How do I maintain this generator?
Basic maintenance is straightforward. Check the oil level before every use, change the oil after the first 20 hours, then every 100 hours after that. The spark plug should be replaced annually or after 300 hours. I also drain the carburetor if I’m storing it for more than a month. The included tool kit has everything you need for basic upkeep. I found the maXpeedingrods MXR3500S surprisingly easy to maintain compared to other generators I’ve owned.
My Final Verdict
After weeks of testing the maXpeedingrods MXR3500S, I can say it delivers on its biggest promises: 24-hour runtime on propane, a lightweight 55-pound design, and three easy start methods. I’d recommend it confidently to RVers and campers who need a portable dual fuel generator. But if you need more than 2800 watts on propane or want dealer-level support, this isn’t your best bet.
The battery requirement for LPG startup is a minor inconvenience, and the 3200 rated watts on gas won’t power a whole house. Still, for the price and portability, I’d absolutely buy this again for my own camping trips. It’s a solid value that gets the job done without breaking your back.
