Liquid propane change to vapor propane is dependent on heat transfed via tank. When the tank ices, there is not enough heat transfer to convert liquid propane to vapor propane therefore the gen was starving for fuel near 9 hr mark. In a real application, just change to another tank then alllow first tank to come ambient temperature. Good test. I am wanting a dual fuel. This was very well done. Thanks.

Thank you for this explanation I’m buying this Generator with remote start for my Rv

[@BigHoss1776]

Thank you for taking the time to run this test. I will be placing my order this weekend.

[@theconnectedcamper]

During your break in I would highly suggest using a magnetic dipstick and changing the oil about 3 times in the first 20 hours. My magnetic dipstick was quite full! www.amazon.com/WEN-55201-Magnetic-Generators-compatible/dp/B07643J11X

[@MikesToolShed]

pretty much the exact video i was looking for, well done

[@borandell9915]

These are good generators and at a very reasonable price. I've had no issues with mine. Great video.

[@dukemanvillle]

I heard that these are loud and are not a good choice for a campground. What has been your experience?

[@GoingNoWhereFast]

Definitely refilling is a pain for propane, but in a normal trailer you have it anyway. Of course I have friends that just add a dispensing port off their car gas tank for their generators. Still can be messy. Too bad you didn't weight the tank after 2 hours to see what it actually consumed. Nice video.

[@pakpalosi777]

Bought this Unit & will Post my Review Soon. Thanks for Sharing the useful Review Information.

[@theconnectedcamper]

Glad it was helpful!

[@danieltimisan6820]

great video ... thank you ! propane thanks do need to vent , they even have a valve for that purpose, but I agree , propane is much better just a little harder to refill

[@SEANRMZ]

thanks, this will be be next gen for the rv, my 2000w works but I am maxing out the output with the ac and solar / battiest charging phase. I need a bit more power and this on is the right size and output thanks

[@theconnectedcamper]

The size and power output of these is impressive! The only downside is the smaller fuel tank, but it isn’t even that big of a deal :) thanks for watching! If you do buy, be sure to use the link in the description!!

[@Jjhornet]

Planning on buying in spring, have you heard about longevity propane vs gas I know when I used to rebuild engines years ago propane would burn our exhaust valves much faster than with gasoline. Great videos helping me decide on next generator, have harbor freight’s predator 3500 works great but a pain lifting in and out of truck

[@theconnectedcamper]

Those predators are great but heavy! Unfortunately no I don’t have any knowledge or data on the longevity of propane vs gasoline on these engines. Thanks for watching :)

Great Video just order one on Amazon Thank you

[@theconnectedcamper]

Hope you enjoy it!

[@headinghome1644]

Excellent test and very helpful. I just purchased got this generator yesterday and wanted to do this test. Any issues with it yet? Do you mainly use it with gas or propane?

[@theconnectedcamper]

No issues with this gen for me. I ran it up to 100 hours then let it go to someone on Facebook. It was difficult to do because it was such a great gen. Thanks for watching!

[@keithpayne8943]

Excellent video. Thanks

[@camustang1966]

This has been my dilemma. I have an on-board propane generator, and a small gas generator as well. Filling propane in some states is a PAIN. Some states/locales are easy. I was in Delaware and it took be over an hour-and-a half to find a place and get my tanks filled, but in Utah it was easy. Varies by state. I am thinking of upgrading to this Genmax generator because it is still less than 60 lbs. My Westinghouse is 47 lbs. and runs at 2,200 Watts…the extra 1k Watts would be nice (plus dual fuel option AND electric start). They won’t deliver it to California, so I’d have to get it while out of state. Thanks for the review and test.

[@theconnectedcamper]

Absolutely, thank you for the reply! This little unit is quite impressive and certainly fills an area of the generator market that was lacking before (2300w to 3000w).

[@chrisneuhaus7188]

Nice demonstration. My only question is why did you run the AC set at 60 degrees. Why not set it at the normal temp you would us it and get a real world results. I'm assuming of course that the AC is able to hold the temp in the trailer at a comfortable level.

[@theconnectedcamper]

Good question! This AC unit doesn’t have a thermostat, so it is like the cold/hot mix when you set your car temp. I also typically left it at the coldest setting, otherwise when the compressor would shut off it would get super humid inside. Thanks for watching :)

[@rickm5251]

Thank you for making this thorough video. I was wondering how is this unit as far as noise levels, I was looking to get one for home use, thanks again.

[@theconnectedcamper]

Hey Rick, I actually have another video comparing this one against the Wen 3800 on noise levels. Check it out here: kzbin.info/www/bejne/r5XSfWmXo9qFp6M

Awesome! Thank you for the quick reply, will check out your video right now!

[@jrdahman]

I purchased the Genmax 3500i (with your link, thank you) and on day one, the first time I pulled it around in my driveway, one of the wheels fell off. I tried sticking it back in but it won't stay in. One wheel is well attached and the other just falls out. Do you have any tips or suggestions on how I can hmget the wheel locked back in???

[@theconnectedcamper]

I would reach out to their customer support and explain it, also include some pictures. They are in China so the response time can be about 24-48 hours, but they have always gotten back to me. Thanks for using the link! Sorry you’re having difficulties!

[@randybobandy9828]

Basically reconfirms what I thought. It's not as cost effective to run on propane. I bought this for a offgrid rv and it won't be here till next week. I specifically got it for the dual fuel combo with the remote. Gas will be my main source but propane is back up because they can sit for years and years. I agree it's also a pain in the butt to get propane filled. There is one place that sells it for 2.79 per gallon but else where is $3.50ish and my closes gas station for 8mile charge $4.50! Employees always seem so bothered when I need propane filled too, especially in the winter. Hopefully this generator is durable because it has all the features I want and it was only $800 on Amazon ($100 off normal price) can't beat the features

[@theconnectedcamper]

Not as cost effective, but if you don't want to deal with smell or old gas, it may be worth it! Thanks for the reply, I agree with everything you've said. The people responsible for filling these never seem thrilled to be doing it haha I can say it is durable! I have about 200 hours on it with several oil changes done and it is working great. I would suggest running 5w-30 full synthetic oil with a magnetic dipstick if at all possible. Link to magnetic dipstick: a.co/d/9is14NY

[@danielleroberts8964]

In Wisconsin, propane is almost always less expensive than gasoline. The 20 lb exchange tanks however, will always be a rip-off.

[@shmit14]

I’ve been trying to find an answer to a question on this generator everywhere…. Can you leave the propane open with this generator and remote start it from inside your camper? Most generators on propane won’t allow you to remote start on propane.

[@theconnectedcamper]

Hey Justin, I set this up and tested this weekend and it worked great. One thing to note is that the first time you start on propane it will need to be primed on the regulator. Basically this just gets the air out of the line and gets the propane into the carb. So that being said, the first time starting it, it should be done with you next to the machine. After that, you should be good to use remote start from within your camper! :) Thanks for the comment!

[@randybobandy9828]

@theconnectedcamper9736 do you mean the very first time you turn it on with propane or everytime you turn it off and back on with propane?

[@SuperNa7ural]

@@randybobandy9828 just the first time you start it with a new can, as long as you keep it connected after that.

[@ballardappraisals1642]

Thanks for the videos on this one. Are you still happy with it? Would you buy it again? Has it given you any trouble since these videos? Thanks

[@theconnectedcamper]

I had this gen up to 120 hours, then sold it to someone with a houseboat. They put 200 hours on it this summer without issue. So it’s at 320ish hours now and has been great. If you’re thinking about buying, please use the link in the description :) thanks for watching!

[@domenicspano4667]

Other than running the generator how do you keep the battery charged for long term storage

[@tristanschaper281]

Great video, especially the long run test and the excel sheet with data. Thank you! I have a Yamaha 2000 inverter gen that I added a propane kit to a few years ago and love it. But I’m thinking about going bigger and this genmax seems to check every box. I especially like the monitoring panel. What are your overall thoughts on quality ? I’ve seen strongly mixed results on this. Of course, that’s not unique to genmax. I set up a champion 2000 gen for a family member and it had loose and cross threaded screws that hold the case and handle together, right out of the box.

[@theconnectedcamper]

Quality for me has been great between the genmax products I've purchased. Other reviewers mention some issues, but if you buy from Amazon you can get a pretty good return/refund policy. I have over 100 hours on my 3500 and it has been great. Break it in properly, have a magnetic dipstick, and keep old gas out of the carb and you should be in good shape! Thanks for the comment and watch :)

@@theconnectedcamper Thank you. I just bought one.

[@jameskrivitsky9715]

Since the tank is building up an ice ring near the bottom, would it help to place the tank near the exhaust end of the Genmax so the heated exhaust warms the tank and melts the ice ? When I worked for a TELCO, we used propane fueled utility trailers and the tanks were near the front of the trailer radiator. Some had "insulated blankets " to protect the tanks on cold days.

[@theconnectedcamper]

I wouldn’t actually recommend having the tanks any closer to the generator. The ice buildup is normal when tanks are being discharged quickly. This video was taken when it was about 80-90 degrees Fahrenheit outside.

[@TimVanVranken]

Have you used your Genmax GM3500Iaed in high elevation areas ? And if so did you have to replace the jet and did you run it on propane or fuel ?

[@theconnectedcamper]

Just a few weeks ago we were at 9,000 feet in Colorado. I did not adjust the carb or jetting and it did fine on 87 octane gasoline. You could tell it was working a little harder, but it still did everything I needed without overloading. Thanks for watching :)

[@halfmoongh]

Is it necessary to use that 30 amp adapter on a 30AMP RV plug? Curious as to why?

[@theconnectedcamper]

Yes! The generator does not come with an RV ready 30 amp plug, so they include this L5-30P to TT-30R plug so you don’t have to buy one to plug your RV into the generator. Thanks for watching!

[@Ojeramup12]

Does the generator originally come with a L5-30 OR L5-20 ?

[@theconnectedcamper]

It does come with an L5-30 to TT-30R adapter. Thanks for watching! :)

[@jrdahman]

Are you still using and happy with the Genmax 3500? I'm considering ditching my Honda eu3200i as it is hard to start sometimes when the temp drops below 40 degrees. I like the duel fuel and electric start on this but want to know if you're still using it after 8 months, or if you've moved on to something else? Thanks! JR

[@theconnectedcamper]

JR, I am still using this and loving it! It has about 115 hours on it with oil changes at 4 hours, 50 hours, and 100 hours while running full synthetic 5w30. Just last week we got dumped on with snow in Colorado. This was outside and in 22 degree weather and the remote start worked flawlessly. Its a super solid machine and you’ll see a 100 hour review of it posted here. If you are considering buying it, i have an affiliate link in the description! Thanks for watching :)

The EU3000i is an expensive unit that has only been out about a year. Honda goes for perfection but it can take a while. Have you reached out to them for support? I am very curious about this because I want to move to an EU3000i when they get the bugs worked out.

[@paullarocque2158]

Does the remote start work when using propane?

[@theconnectedcamper]

To restart after it has been running, yes it does work. The problem is propane does need to be primed when starting to purge air from the lines. Priming can only be done on the regulator on the generator, so remote start probably wouldn’t work. Thanks for watching :)

[@paullarocque2158]

@@theconnectedcamper Thanks, that makes sense.

[@rob21]

I read a review about changing oil may tip the gas out. Is that your experience?

[@theconnectedcamper]

I always have the gen as low on gas as possible before an oil change. I can see how if the tank was full, the overflow would have it leak out through the carbon filter and likely have it run poorly as well as leak gasoline on the group. Long story short, change the oil with the gas as low as possible, this will help prevent spills.

[@tedc6694]

Volume compared to Honda?

[@theconnectedcamper]

Not much louder, Hondas are quiet, but you pay for it. These are far more economical :) thanks for watching :)

I saw your video on the WEN 3800. Did you determine how long both generators run on a 20lb propane tank at the same load?

[@theconnectedcamper]

My WEN is actually just single fuel, so no propane there unless I did a conversion kit to the carb. Possible, but not planned at the moment. Thanks for the comment :)

[@stephencrandellsr4915]

My only drawback with this generator is the regular they use it would be so much easier on my camper to hook up directly to the propane outlet for the grill instead of disconnecting one of my propane tanks and using their regulator

[@theconnectedcamper]

hmm the problem you're running into is a double regulator scenario. You have the regulator on your camper that will set the pressure, then the regulator on the generator that isn't getting the expected pressure. I would suggest just connecting directly to tanks.

[@stephencrandellsr4915]

@@theconnectedcamper i would not run two regulators would run a straight hose from the cooker connection yo the gen but no way to purge the air out of the line ☹

[@danpatnode6783]

Propane generators need two regulators, one to limit pressure and one to limit flow. If it stalls without the second, gas will just keep flowing. BBQ only regulators expect you to stop the flow manually when turning off.

[@tmanning4usa]

But if propane costs 3 times as much than gas it just ain't worth it especially at today's costs of fuel now the only thing about propane to me is that it can be stored a long time.
