Great quality and worth the money
We use this on our 2024 Airstream 30 GT. I have only run it using the onboard propane quick connect. Runs fine with a straight hose with no regulator as the AS already has a regulator. Plenty quiet enough and starts easy. I’m sure it would produce more energy on gasoline but I’ve never put gas in it

Lightweight Powerhouse!
Full disclosure- i've only owned this 4000W Duel Fuel generator for 3 weeks, but I've already had some good use from it and I've been very impressed thus far! I bought this to power my truck camper, and specifically my A/C on the truck camper when it's very hot. I had been carrying a 2000W Firman gas-only generator prior, and while I can run the A/C on the camper from that, it is nearly maxxed out when I do so I don't think I could run it for long if necessary, and there is the issue of carrying gas. The storage compartment of my camper requires laying the generator almost on its side to get it in/out of the compartment, and I've had gasoline leak into the compartment prior when doing so. No Bueno!! So I bought this generator, which is virtually the same size and weight as my Firman (which otherwise I've been very impressed with as well, btw) but allows me to operate from the on-board propane tanks located in my truck camper. It's clean and convenient to do so, and this generator runs pretty quietly given it can put out 3,200W continuously and 4,000 surge watts if necessary! It also produces a clean sine wave signal, so I don't have to worry about frying my cellphone, laptops, etc while charging. It is a few decibels louder than a Honda 2000i or 2200i, but close to 2 x's the output for a few decibels more. And at lighter loads on eco mode it is still very quiet (which is where it will operate most of the time I'm using it; less than 50% load.) I bought it and broke it in and tucked it away in the camper to take to the Sierra for one last skiing weekend, and lo and behold, it saved my butt when my diesel fuel gelled and I had to run the Pulsar for 3 hours to power my truck's block heater to get it started! My Firman could have handled the 700-800W draw as well, but again, nice to pull it out, hook it to the propane extension and fire it up. On that note, with propane I do need to give it a pull or two on choke before it starts on propane, but it runs perfectly once I do so. I'm at the 5 hour mark so I'll change the oil again tomorrow which should be the last maintenance I need for awhile. I really can't believe I found a propane generator with twice the capacity as my Firman 2k/1,600W gas generator for $500 (caught a sale on Amazon.) If my experience changes over time I'll update, but so far I'm very satisfied with this Pulsar Dual Fuel generator!

Works great.
Runs great on propane. Starts on second pull and runs my 30 amp travel trailer with no problem. This unit is very quiet and light weight.

Powerful, Portable, and Good To Go
The new Pulsar G2319N is one of the new breed of lightweight generators encased in plastic. It weights around fifty pounds and is highly portable. We set up the device following the recommendations of other buyers that suggested: 1) Use "synthetic" motor oil. We use the least expensive synthetic motor oil of the right weight from WalMart. 2) Install an new oil plug with a built-in magnet to catch metal filings. (And sure enough, there are metal filings the oil plug has caught and stopped from circulating in the engine.) 3) Change the oil every forty hours and after first breaking in the engine. So far, the generator has worked well as an external power source for power tools like a portable air compressor, an electric chain saw, drills, an electric pressure cleaner, an electric torque wrench, and a reciprocating saw. The generator starts consistently on the first or second pull of the cord and runs as long as needed without any fiddling or maintenance, aside from adding fuel. As other buyers have reported, there's an engine surge in this generator when it runs and it must be a idiosyncratic condition of this engine's design; it speeds up and slows down, and if it was a car engine surging like this we would be concerned, but this is a little one cylinder gas engine. We started adding a small amount of "STA-BIL" -- 'Fast Fix,' small engine treatment -- as a fuel additive when we add gas to the generator, and that helps to smooth out the engine. There is still a slight engine surge even after the fuel additive but you have to listen for it. ("STA-BIL - Fast Fix" fuel treatment is great stuff, and it saved us the trouble of taking our twenty year old Honda generator's carburetor apart for cleaning or replacement). There is no external fuel gauge on the Pulsar G2319N but run times on a full tank seems to be around four hours. This is a good running generator and seems to be well made but it needs to get careful treatment, it has a plastic body and can't be banged around or handled roughly. These style of small gas generators have been on the market for a number of years so they've probably worked the bugs out of them, but there's always a question about longevity - how long they are going to last. This type of generator is probably not going to hold up running all day on a job-site, but it's handy and lightweight enough to carry along for those times electric power is needed.

Pulsar Generator
This Pulsar model is relatively simple to operate and starts easily, runs on gas or propane and is very quiet. The generator is light enough to easily pack. Pleased with this generator. Priced very reasonably.

Does not run on gas
Would not run on gas. Well I am on the second generator and the second one still does not run on gas. I tried to return the generator for a refund but Amazon will not refund your money. I could not find this exception anyplace. I tried to get my money back from pulsar and they said you need to go back to who you bought it for a refund. What a scam. I would recommend that no one buys this generator especially from Amazon. Update Talked to Ricky at Amazon and he was able to resolve the issue. Very helpful and polite. Thanks Ricky.

Efficient, Small, Quiet, and Capable
*Update 1/17/24* Still working great, still running it only on propane. We have been having single digit temperature weather and I have been able to get the generator started relatively easy to run the block heater on my truck. Truck is parked far enough from an outlet that it's easier to turn on the generator to get power by the truck that way. When power went out it was also great to have the electronic safe power that this provided. Starlink internet kept the home entertained, the generator ran other electronics, and propane kept us heated. Overall, still very happy with the generator. Have not run the generator on gas, only have ran mine on propane. Generator ships with all you need to get started, except the fuel source. Oil funnel is also used to drain the oil. Makes it very mess free for oil changes. Which I recommend changing after the first hour, since there's all kind of glitter in the first oil change. I then ran it another couple hours and changed again. Much cleaner this time. Holds 15 ounces of oil so a standard quart of oil can do two oil changes. In total I changed the oil three times during the break in before switching in full synthetic oil. It runs very quiet and stays pretty quiet under load. Quieter than a smaller 700 watt inverter generator I have and while not as fuel efficient it is still very economical with how much propane it uses. Revs up to produce power and has run my 10,000 btu window ac without issue. Ran a 5,000 btu and small .7 cubic foot microwave at the same time off of it. I love the size of this unit for the amount of power it produces. You can parallel two of them if you need more power. Really the only downsides I have would be no electric start, and the outlet selection is sparse. Got mine with coupon off of Amazon and have no regrets so far. Will update if anything negative happens

Very good small generator
Well built, compact design, can be paralleled with another generator of the same model for more amperage. You will need a special cable to do that though. This is an inverter generator, it produces "clean" power that is safe for electronics. Unit is exactly as advertised. I sell generators, but they start at 35 kW and go up to 125 kW, not really the portable kind. I'm just mentioning that to say I am familiar with generators
