Customers Feedback:

3 am and my computer’s UPS beeping wakes me up. Yep power is out. Went outside connected propane tank and started it right up. I got this generator because our utility co has regular outages. Its the first time I’ve had to use it though, and it worked like a charm. The included wheel kit makes it super easy to move around. It’s not an inverter so I wasn’t expecting it to be quiet, but it didn’t wake up the rest of the family.

Ordered two days ago and it arrived today. Packaging was intact. It comes with a tool kit and tiny jumper cables. It does NOT come with oil. I had to run to the filling station for that. Read the instructions, fired up on first try on propane , and ran my camper AC for 15 minutes as a test. It’s hurricane season, y’all. I think I’m ready.

Customers Feedback:

Great price/value. I already have two Honda 2000’s. I use them with my RV trailer and also as backup for the house when the power goes out. I love my Honda’s so I was a bit skeptical about another brand and also the noise. I wanted a dual fuel option and also one that could power my 30amp AC on the RV. This generator is just slightly louder than the Honda’s but not enough to really notice. Power wise, it’s great. I love that it comes with the handle and wheels. I would buy another one of these when/if the time comes.

I was warned that this neighborhood went nearly a week without power after Sandy so I decided to get a new generator that would run when I want it to and not be so loud that people would complain. We just got smashed by a winter storm, but I have heat and light. it runs everything I need to and I can switch between propane and gasoline. My neighbors can’t hear it running but the lights and TV give me away. It’s very efficient and quiet. I bought a couple extra propane cylinders to keep it spinning for a few days. I added an hour meter so that I can change the oil on schedule. The electric start is positively decadent.

Customers Feedback:

FYI.. I am a senior that actually started and hooked it up on my own. This is so slick! Love it but hope I never have to use it. Live in snow country and wanted to be self sufficient should my power go out. This will do the trick nicely.Great purchase.

Saw me through Hurricane Irma when I was out of power for 13 days. I’m an older female and had no problem adding the wheels and using the generator. Ran my refrigerator/freezer, portable air conditioner and lights and could have run more. I used gasoline but it takes propane. Takes about 3 gallons of gas and runs for 10-12 hours. Don’t let the ball in the gas tank fool you that it’s full. At first I wasn’t adding enough gas – it does take at least 2 1/2 gallons.

If I get 5 years out of this I will be happy. Packaging was great. Assembly was eh. Hardware is junk. I used some grade 8 stuff I had after I stripped a bolt. Thats really my only complaint. Wish I knew how much run time I will actually get on propane. Instructions vs what everyone says is different. Made a little house for mine to keep the rain off.

I purchased a pulsar 12000 watt generator. Delivered on time. Started straight up. Has electric start that starts each time. Had a cracked front cover plate and both amazon and the distributor worked together to have a new cover plate replacement sent as l did not want to return the generator it works so well.

XP13000EH was delivered well packaged and in excellent condition. Put it together and had it running inside an hour; just follow instructions. Flushed crankcase and refilled with 10W-30 Synthetic oil. This is a very nice machine and well built. Pulls the rated wattage (only ran gas so far). My boys and I agree it runs quieter than the 9500 Hxxxx BxxxMxx it replaced. Customer service is excellent, answering questions before purchase and after purchase. So far I couldn’t be happier with this 500cc, 20HP, 13kW/10.5kW beast (just keep an eye on the auto choke). Only wish I could have afforded the 713cc V-Twin. Thank you DuroMax!

One of my best purchase of the yr. Our power goes out on the regular. In one yr we had to use the generator quite a bit from 6 to 12 hr power outage to 3 day power outage from hurricane harvey. It runs full load six hrs so it runs refrigerator, several lights, 2 5k btu window units fans and coffee pot with no problems for six hrs oh and one small deep freeze. It so easy to use I work away from home so my wife is the using it most and she loves. Only time will tell if its truly a great buy.

Got this in the aftermath of hurricane Maria. This is a really good generator and I am pleased with the purchase. This is our second unit and we use it at night. It has enough power for a 18,000 watt AC, freezer, fridge, lights, two fans and lasts 9-10 hours on a full gas tank. The remote control is extremely convenient and useful for us aging folks. The noise level is not bad – much better than our 5500 CAT unit. Highly recommended.

Great generator i run on propane, ran upright frost free freezer an a 3/4horse bench grinder same time it handled starting watts no problem, ran 15 amp circular saw, didn’t phase it, but in shipping something fell on it put big dent in gas tank popped most of it out using propane anyway an bent the frame but i was able to straighten most of it, works great starts rite up, they need stronger battery cable ends to battery, wires vibrate alot,not a big deal easy fix, this is a neutral ground bonded at frame, not floating neutral

Bought this unit off Amazon. I had used one of their smaller gens at work that was so quiet and ran like a champ. After receiving this gen I opened the box installed wheels and removed shipping brackets, hooked up battery. Noticed the oil that was sent with the gen had leaked out of oil bottle. All is good no problem, put oil in gen hooked it up to a propane tank and this bad boy started right up. NICE!!! Haven’t tested it on gas yet. A little noisier then I thought but still more quiet then most.

FAQs on the Best Dual Fuel Inverter Generator for 2021

Can your dual fuel inverter generator be connected to your home?

No, you cannot connect the portable dual fuel generator in your home, and people advise not to connect it directly to any electrical appliances in your home. The reason behind this is that it can cause electrocution which can cause damage to the electric devices that are connected with it and can also cause death to you and is therefore very risky work.

To prevent any possible damage it is recommended to install the transfer switch in your product. Also, an experienced electrician is required to do such a task and you must not do it on your own getting an electric shock of high voltage.

Can you run your dual fuel inverter generator continuously for non-stop?

It all depends on the maintenance that you provide to your product to run it continuously for non-stop. While fuelling your product with gasoline, it is important to stop the generator at that time as the gasoline is very flammable and can cause fire and wait for a while to let it cool down.

It will help you in taking care of a portable generator and also give attention to its maintenance. When your inverter generator dual fuel is under any load then you must not let it run out of fuel and keep the tank always full or else it may harm all the devices connected to it.

What happens if you overload your dual fuel inverter generator?

There are many generators available in the market that prevent themselves from their engine from the overloading by having proper use of the circuit breaker.

If the engine is overloaded then the circuit breaker present and it will get a trip which will eventually stop the flow of power for protecting your generator and also the other devices connected to it. The circuit breakers require only 10 seconds to get cool down and then after that you can reset your machine by pressing the button of the breakers again.

Can you use your dual fuel inverter generator with an extension cord?

Yes, you can run your portable generator on the extension cord. Moreover, you must use the extension cord which is small as the long one will cause a drop in the voltage.

For every 10 meters of the cord, there is a 2-3 drop of voltage and there is a 5 to 6 drop of voltage in the 20 meters of cord, and in case you are using a cord of 30 then there is a voltage drop of 8 to 10 volts. Therefore, the extension cord with long length is not recommended to use with your portable inverter generator.

How to setup Dual Fuel Inverter Generator?

Video Transcript:

Generator power source calm here for an initial setup video of the champion dual fuel 3500 we just took this out of the box in order to get it set up you got a few things to do this is an electric start so we have a battery on board in this unit first thing we’re going to do is show you how to add oil to the machine then we’ll connect the battery and then add fuel we’re going to run gasoline first but this unit will also run propane you have a propane connection right here so you can either use gasoline or propane so first up we’re going to take off the back panel and this is a relatively self-explanatory there are two screws on the backside of this panel I’ve already taken the screws out.

You’re just going to remove this panel here on the back and that will reveal the oil fill so as you can see it recommends 10w30 we’re running 10w30 because it’s quite warm here in Florida so we’ll go ahead and remove that and add this unit calls for 600 milliliters so 0.6 liters of oil before you start and again it has a dipstick you’ll see that most of these have oil on them already because they’re tested at the unit so we’ll go ahead and add the first 200 milliliters so we got to do this a couple of times to add the oil this is just the funnel that we’re working with here it’s kind of slow now that we’ve added 600 milliliters of oil we’ll check it with the dipstick always a good idea to check your generator.

Before you run it anyways especially if it’s been sitting for a while check make sure that we’re on up as you can see we’re almost to the max and put that back on put the back cover on and move on to connecting the battery again because this generator has an electric start so I’ll show you how this back panel goes on as well relatively straightforward two screws slides in like this and then you have two screws here now we’ll move on to connecting the battery this back panel just comes off saying the same exact way that we just did with the oil compartment same setup as we saw on the Energizer setup this is just a strap that secures the battery in place and then we’ll go ahead and remove the battery from here the cables are tied up inside of it there’s the negative-positive is still connected I think nope there we go remove the battery out connect the terminals.

If we can do this here these come with screws already on them so you don’t have to even remove them from the kit let’s go ahead and put your terminal covers off let’s just slide over the top and then slide the battery back up in there and guide the cables back up in there and then again it’s just a just an elastic strap that goes across the top across the front of it that keeps it in place terminal covers are on and we’ll put the panel back on be ready to add some fuel and fire this thing up that’s but not least we’ll go ahead and add some fuel threaded cap top and it is connected that’s a nice little feature throw some gas in it make sure we get it running that’s good for starting.

And you’ll see on the front like we showed you have the option for fuel or for propane so right now we’re running fuel you cover up the propane you’re running Iran and gasoline and manual choke on the front you have the electric start right here so we’re going to go ahead and see if this baby will run you have a battery here as well so go ahead and turn that on and turn it on and see if we can get this running there you go really quiet okay right next to it and you can see not very loud and it’s 3,500 so that’s the initial setup of the champion I’ve got the choke in there you go so there you have it we’re running right now we’re on economy mode not very loud it’s a little bit louder.

Then some of the other inverter generators but we’re going to test all of them lined up next to each other with a decibel meter from different distances as well as with and without a load this model comes with an economy so if you want to you can crank it up but that’s been the initial setup for the champion duel fuel 3500 we’ll be back with a full review after this.

Is it good for your dual fuel inverter generator to refill the oil?

To extend the life of your dual fuel generators portable, it is recommended not to refill the tank with oil. And in place of it, you must always change the whole amount of oil. The motive behind this is that the engine oil when exposed to the heat of the engine.

It gets ruin and is of no further use. Furthermore, if you use your engine without changing the oil then it will cause damage to the components and this damage is for a long time. It will affect not only the efficiency of its performance but also the life of your device.

What will happen if the amount of oil used in the dual fuel inverter generator is not adequate?

If you are using your portable generator with a not adequate amount of oil in it then it may increase the resistance of your engine. With the increase in resistance, the oil may get leak out and there may be an emission of the white smoke from the exhaust panel.

which may eventually make the efficiency of its performance decrease. When there is a low amount of oil in your product then there is a caution system that gets reactivates which warns you about the low oil. Moreover, the engine of your generators with remote start stops and protects the motor from getting burnt.

How To Change Your Oil Champion Dual Fuel Generator?

Video Transcript:

Let me show you how to change the oil on de champion 100 to 97 model number generator duel fuel or the 10,000-watt generator Pete knows man you have a 15-millimeter wrench or socket you put on here that’s where you drain it you can put in a little pin under here heat up run the generator for like 10 minutes to heat up the oil open it open this up.

So this air just what I do is I take the bolt outlet it drain and I take out the dipstick now you fill it up now it comes with this funnel-like I said don’t lose it because it’s perfect for pouring oil into here now what I put in here is 10w30 now 5w30 to full synthetic and to check a Chinese generator as people say you don’t screw this in with the dipstick.

What you do is you just put it here bottom it up flush it and look at it and it tells you if it’s full or not go like this take a look at it’ll give you a reading if you screw it in according to our video a who works on engines small engines he said this will give you a false reading because it’s too deep and I will check with champion one more time.

Before I post this but yep it shows it shows it fault wait for I call champion generator and they told me the safe easiest way to do this it fills this to the second to the third threat of thread and it would be fine and that’s the quickest way when I want to check the oil I open it up I take a look then seal it down I don’t even look at the dips after you drain you all put this back infill it to the second thread as I said and you’re done.

Now I’m using full synthetic but I’m doing the same cycle 50 hours on heavy load 100 hours on regular load I’m on the 100-hour cycle and I only have 14 hours on this generator I thank for it I don’t you think it’s 14 hours or 20 it’s low so make sure you monitor your hours and you change your oil it’s crucial now I’m one of my friends had a hurricane in Florida and he broke his generator in and ran out of oil he ran in for two weeks and he all the stores were closed.

And that’s it he had tons of gas but no oil I have 5 quarts 5 bottles of 5 quarts of oil I have over 500 hours easily of run time on my generator even more than that so how have at least 5 quarts of oil on if you’re gonna have to ride out through a hurricane and everything so I’m ready for Armageddon so I’m ready to go any questions put in the comment section.
