I had a WEN Gen Duel Fuel i4000w and Loved it. I became ill and was not able to lift it. #1 PUT REGULAR OIL IN IT. THEN MAKE SURE YOU RUN UNIT 30-40 MINUTES with medium load and idle !! CHANGE THE OIL !! Then Run unit again 30-40 minutes half to medium load. THEN CHANGE ( Look for Metal Flakes in oil ) if good drain and refill with the oil of choice( I like Valovine Motorcycle synthetic 10-30. If Flakes still visible Run as many times as necessary to remove all flakes ( average 3-4 times ) This Eliminates head aches and major problems down the road or off road. I used this Pulsar 4000 for a 34’ rv dual AC, two refrigerators 120 & 12v this unit WILL run one AC 15,000 btu’s 1690 run watts along with several other appliances.

I purchased this mainly for our camper to run the AC and other items on the RV. I really like the power and how compact it is. Works great on propane. I have yet to use it with gasoline. I like that the receptacle matches the plug so no adapters needed. Some things I do not like. 1. I cut my nail nearly off when pull starting. My finger caught the chrome bezel and it tore a chunk of nail off. I am more careful now. 2. It rattles. The handle rattles and makes a horrendous noise so I just prop something under the handle. I think the wheels rattle too but do not appear to be as bad, tolerable. 3. The display is good but very confusing and possibly not even accurate. As I toggle through the modes the hour meter does not seem to change. Maybe over time it will make more sense. If not I will put my own hour meter on it. At this point I would recommend and buy again. ... show more

    • Great portable generator easy set up

Review Image by Herb Herb
This generator is great propane/gas. I'm using it for propane only to keep it smelling clean and storing indoors. Set up was simple take out of box, add oil plug in the propane cable turn on and set to choke and pull cable. Easily started within 5 pulls. I heard it starts easier on run with propane instead of choke. This generator is light about 50 pounds and has wheels to make it extremely portable. It's not loud either I ran it in my back yard and can barely hear it from the front yard. Ready the next time my power goes out! ... show more

    • Not Worth the Money
Style: 4000 Watts - Dual Fuel - Wheel Kit - Wit...
Do not purchase the GX400BN 4000 watt generator. We were going camping the Labor Day weekend. Took it out of the box, put oil in it and put gasoline in it. Set all the buttons and pulled the cord, and I pulled the cord, over and over, would not start. Waited until Tuesday to call them. Their customer service is a joke also. I talked to a person who told me to do this and do that and even hooked it up to propane and it never would start. She wanted me to give her the serial number of the generator. It was not on the machine, it was not on the box. She told me it was also to the left of the oil dipstick on the motor. There was no serial number I could find. I told that to the second person also. Once again I found no serial number. So I would not purchase the pulsar 4000 watt generator. ... show more

I love that this generator is compact to take anywhere from the jobsite to the campsite. This powers any tool I need on the job and powers everything on my small camper including the AC. I have only ever used LP but I do love the fact that it’s also dual fuel.

At the time of this writing I have had the generator for a couple of months. Up front, the first two things you need to do to this generator at the time I got this generator (January 2024) is to replace the spark plug installed by the factory with a real spark plug and adjust the valve lash clearances. These two things straight out of the factory are just unacceptably wrong and will ruin your day. Once you accept this and get it fixed, which isn't too hard to do really, this generator runs a whole lot better, especially if you are trying to run it on propane. Not saying buttery smooth. I have to wonder if getting the valve lash clearances fixed before starting up would fix the last bit of roughness I haven't been able to work out by other means, granted those other means helped out a lot, just not all done up front before starting for the first time. In addition to the 2 things you need to do out of the box, I also added a magnetic dip stick as per Mr Garage and others recommending it as these do not have an oil filter. While not an oil filter, it does collect up a lot of crud and needs to be cleaned after every run, effectively taking that crud out of the engine. Better than having nothing there and just having more crud in your engine wearing it out faster. As for oil and breaking in and such, remember all of these small generators don't have a real oil filter and these compact and light generators can spin up to 4,850 RPM when under full load. Your standard car engine with an oil filter when you work out a little math and rough conversation is supposed to have its oil changed every 100 hours or so in generator time. So this without an oil filter, you really want frequent changes at first as the engine breaks in while the oil gets crudded up with metal shavings and such and then still a lot more frequent than a car engine in generator time once broken in. The manual says first oil change at 25 hours and then every 50 hours after that. I would say by 25 hours you should be on your 3rd oil change, not your first, and then change it out every 30 hours or so, especially if you load it up. Then of course with a max loaded RPM of 4,850 RPM, you don't want to peg this thing out much. Maybe keep no more than 50% sustained load and higher is for peek demands like starting electric motors. At this you need any big motors to soft start. As I just have not run the generator all that much, but am now running on propane, I will check to see if propane keeps the oil cleaner. May end up doing 50 hour oil changes after the full break-in period just due to propane likely not cruding things up as much. Break-in period definitely needs frequent oil changes to get all of the metal shavings and any other stuff like assembly lube fully out. Will have to see after the next 30 hour mark. As far as I am concerned propane is the way to run a generator like this unless you have to run it on gasoline. Propane lasts forever, pollutes a lot less, and because it burns a lot cleaner, a lot less crud building up in your engine and exhaust system that you have to clean later. It is important to point out that this is a "floating neutral" generator just like pretty much all of the other small inverter generators coming out of China. It does not say so, which is a NEC code violation. Really, I can't think of a practical use for this generator where you wouldn't need to bond at the generator, so a bit of a disappointment that China does not bond these small 120V only generators at the factory. Also, by default all of these generators are unsafe unless and are putting out a lot of electrical noise unless you correct it through bonding. You can get a cheap NEMA 5-15 bonding plug. This works for this generator, correcting the issue on all outlets. I have put together a bonded TT-30 adapter cable. I think it is a better idea when using a 30A (or higher) outlet to use wiring rated for 30A as the ground - neutral bond needs be able to pass enough short circuit current to pop at 30A breaker, thus clearing a fault to ground. The reason for making the adapter cable over slicing up my existing extension cable is once a cable has a ground-neutral bond in it, it can only be used with the generator as creating a double bond in another electrical system, say connecting your travel trailer to your house or camp ground power, is against NEC codes and will create a ground loop, a big no-no. The wheel kit on this generator is nearly useless. I would say either secure it so it doesn't rattle with a tip being the cotter pins come out a lot easier if you rotate them sideways first or just take the wheel kit off. This generator has a nice handle on the top and is easy enough to just pick up and carry around. There is a lot to like about this generator. For the price, it is hard to beat on this feature set and compact size. Granted the wheel kit is nearly useless and if you are running on propane, you don't need a 2 gallon fuel tank, though in an emergency situation I would still like to have a gas tank in case I can't source propane. A 1-gallon tank of the older model under the loads I would put this generator under for backup power, especially when running an A/C / heat-pump off of it just wouldn't last very long. Granted you could hook up an external fuel tank and fuel pump to have all of the gasoline you want. Either with gasoline or propane, you could rig up something to have all of the fuel you need. Just remember to change the oil and clean the air filter after so many hours of running. Also remember that gasoline as your local gas station may contain ethanol, which is food, and that food in your fuel goes bad quickly and will ruin your day if you store it for too long / it sits in the carburetor for too long, especially without putting fuel stabilizer in it, thus why I like propane so much for this generator. For all around capability of this generator, so far what I am seeing is there is a lot of good stuff packed into a small and reasonably light package. It produces its rated power and never gets that loud. The neighbors for the most part cannot hear it in their homes and I cannot hear it from the street. I swear it sounds quieter on propane. That 2 db they mention is noticeable. I also went for a long TT-30 extension cord as pulling power over 10 gauge wire has less voltage drop than 14 gauge NEMA 5-15 extension cords for the same amp draw and you can go up to the rated wattage of the generator with such an extension cord. The long part allows me to keep the generator further away from everyone for the quietest possible operation from anyone's perspective. The goal usually is to have a 6V drop or less, so say a 75 ft TT-30 extension cable should not get much above a 4V drop with this generator. If my readings are correct, I am seeing less voltage drop over my extension cable than calculated. Don't forget you need to operate this generator in open spaces, so if you don't have anything open enough near where you need it, you need to extend out until you can achieve this. Maybe at most you put a table over the generator if it is raining outside to keep the generator dry and not in a spot where it will flood. As for sourcing propane, around where I live at least, it is far cheaper to get a good sized propane tank, such as 30 lbs, and then fill it up at a local propane fueling station. Going to a local gas station to do a 15 lbs propane tank buy / swap is twice as expensive for each unit of fuel held / bought. Also, if you are really looking for all day operation, 30 lbs of propane will last ~ 2x as long as a full tank of gasoline. You may point out that the gallon rate on propane is higher (less fuel efficient), but these generators are optimized for low octane gasoline and just can't take advantage of the higher octane rating of propane, at least from what I hear. I found a tank with a built in float based gauge that uses magnets to move the needle on the external gauge from the internal (under pressure) float. So I can watch the fuel usage in addition to using a scale to weigh the tank and see how many lbs of propane are left. Don't forget that propane is a liquid / gas like water / steam is a liquid / gas. It is just that as propane is a natural refrigerant, it condenses into a liquid at a higher pressure / lower temperature than H2O. At least compared to CNG (compressed natural gas), propane is far more dense as it turns into a liquid at a low enough pressure (~100 PSIG at 75F and ~300 PSIG at 140 F) where CNG is a much more diffuse high pressure gas, even at 3,600 PSIG of your typical truck tank. (I am much more comfortable with the idea of working with up to a few hundred PSIG than a few thousand PSIG anyway.) In other words, the real ways to measure propane is a float in the tank like the float in the tank of your toilet and just weighing the tank and taking deltas. The gauge on my tanks isn't super accurate, but it is getting the job done. Like 1/3rd of the tank gets used before the needle moves when also measuring by scale, then there is a middle band where the float based gauge actually works. Something to point out is this generator is a compromise of sorts. This generator has a lot of stuff other generators have stripped off to make it lighter and cheaper. It still does the job fine, at least if you are looking for periodic / occasional / emergency use generator and you don't mind pull starting the generator. Pull starting this generator for middle aged on down and not too beaten up yet is plenty easy, especially when you know the tricks to quickly starting it. If you are an old man with an RV and everything on your body hurts, this is probably not the generator for you. A total of 2 stars knocked off. One for having valve lash clearances that are way off from the factory. Second, a crappy spark plug. Granted, this seems to be a common problem with these generators, but still what comes out of the factory will ruin your day if you don't immediately change it out. I mean it is really that bad. Then not happy with the wheel kit on this thing. These are all fixable issues. Hopefully they make some updates to how they put this together, maybe even drop the wheel kit as it is not needed or at least modify it to be useful and then this could be a great generator like its predecessor. Even better because it has more modern stuff on it like a digital display providing all kinds of useful information. ... show more
