    • Great for high power DJ equipment!
Style: 4000 Watts + Dual Fuel + Lightweight + R...
I am so glad I got this generator! I have a Honda 3000 from over a decade ago, but that thing is huge to try and move around (it takes two people to load it into the bed of a pickup truck). I can carry this with one hand, and it has the same power output rating, and I can (and do) run it for much longer with an LP tank! LP gas lasts forever practically! I use it to charge up my Ecoflow Delta 2 on non-sunny days, or if I want to run all of my speakers all night long! At this price, I can get two! ... show more

    • Quieter than I expected.
Style: 4000 Watts + Dual Fuel + Lightweight + R...
I will start with some numbers: It started on the 8th pull on propane, I alternated between two pulls on choke and two pulls on run, on the 8th pull it started. I did bleed the air out of the propane hose before trying to start it, idle was turned Off and it ran unexpectedly smooth and quiet I have to admit that was a pleasant surprise. Sound level no load was 58 to 59 decibels 20 ft away (high speed), it was sitting on concrete. It ran on idle at 3,240 RPMs and 3,860 RPMs at high speed no load. I let it run for about 10 minutes before putting a load on it, first load a heater running at1,380 Watts second load another heater running at 860 Watts. So about 2,240 w at 120 volts, I did not have an adapter during the test to use the 30 amp outlet so I had to run the test out of the 20 amp outlet, I was using about 18.6 amps and I was starting to feel uncomfortable with that number, the outlet was warm and the spades on the extension were hot to the touch so I did not add any more loads, I recommend treating the 20 amp outlet as a 15 amp max outlet to avoid a problem. The engine RPM with the two loads was between 4,260 and 4,280 RPMs, I ran the engine a total of 25 minutes. Full disclosure, I installed an hour and RPM meter myself that's where I got the numbers from, I used a phone app to measure decibels UPDATE: Feb 4 2025. It started cold on 3rd pull. I now have the 30 amp adapter that I needed and I connected to a 50' extension and back to a 3 outlet - 20 amp connector, I installed 3 Kill a Watt meters and a heater to each one of the 20 amp outlets, I used different heat settings to try different loads, At ~2,720 watts the RPM's were ~4,580, at ~3,100 watts* the RPM's were ~4,610. The generator ran smooth and the green indicator was solid, it ran about 5 minutes at the max load no problems on Propane. * The RPM.s and wattage were variables and I used an average. I had a one hour timer for running time, I removed all loads at the 50 min mark and set the generator on idle speed and let it cool down. I turned it off waited 5 minutes and it started on one pull, turned it off again waited another 5 and it started on the first pull again. I changed the oil while it was hot and used 10W30 full synthetic. I know 1.1 hours prove nothing as far as longevity but it met and slightly surpassed manufacturers specs. 118.7 Volts at full load. 59.9 Hertz at full load 26.12 Amps at full load I hope this information is found helpful. ... show more

Style: 4000 Watts + Dual Fuel + Lightweight + R...
This generator has a few quirks, but runs great , 1st quirk do not leave in the full sun ever, needs to be the shade to run the AC, runs on both propane and gas. 2nd quirk and it has been mentioned in other reviews it will vapor lock on gas, easy fix take out the filter on the breather cap so it can breath, the filter is to fine and restricts airflow, runs like a champ on gas without the filter, we have had this generator for 3 years, and recommended to our son to buy one. ... show more

    • Not reliable
Style: 4000 Watts + Dual Fuel + Lightweight + R...
After purchasing this generator I followed the instructions and did the break-in procedure, would not start on propane but was able to get running on gas then switched over to propane. Did the oil change and put it away for several months over the winter with fuel drained. Going camping this week and decided to test run the generator. 2 hours of no start pull starting and I dug in. No spark. Disconnected the low oil sensor wire (yes, checked the oil level early on) and it fired. Reconnected the low oil wire and it died. Tested unit with low oil shut down disconnected and seems fine, maybe! Cannot recommend this product, don't buy one. I was ready to get another to connect in series to run a RV AC, no way will I buy another! Nor should you! ... show more

    • Reliable Dual Fuel Generator
Style: 4000 Watts + Dual Fuel + Lightweight + R...
This generator is a powerhouse, running smoothly on both propane and gas. Just remember to keep it shaded for optimal AC performance. One minor issue is the potential for vapor lock on gas, but a simple fix by removing the breather cap filter allows it to run like a champ. Despite these quirks, after three years of owning it, we highly recommend this generator - in fact, we suggested our son get one too! ... show more
