Awesome little generator. My honda 2000w wouldn’t run the AC in my cab over camper it would just overload. This runs it no problem and still just as small & portable. ( Fits right thru my camper door ) Not as quiet but overall a strong machine. I did a solid break in process much like another reviewer mentioned & there was some bits of metallic in the first few oils changes and on the magnetic dip stick I added ( all normal for engine break in ) I would recommend changing the spark plug out for a NGK if possible, the torch provided in my unit had a small miss just after a few hours of operation & can slightly tell in the video i’ll post but nothing major. Very easy to use and fire up with the all in 1 choke / run / kill switch. Overall happy with the unit & would highly recommend this unit to anyone asking.

Picked this up to run the a/c and charge my camper battery. (My 2000 watt one wasn't string enough to do both, this one should have plenty of power) Breaking it in now. So far it's been going great. Will update after hard use.*This is 3500 watt not the advertised 3400 watt.*I seen complaints about the spark plug being hard to access but a spark plug socket and a simple extension makes it pretty easy.Very nice accessories included that you don't even see on name brand.Things I changed to make life easier with a budget generator:1: Upgraded the sparkplug to a hotter iridian one. (Easier starting the the cheap generic one included)2: spray a small amount of k and n air filter oil on the air filter and dab out access with a rag.3: replaced dipstick with magnetic dip stick. (There's no oil filter, this is huge!)Manual says to change oil after 20 hours of use. As with any small engine this is terrible advice and a quick way to make these generators only a one or two season machine.Proper break in: use 10-30 mineral based break-in oil with zinc. Break in 6 sessions all non echo use a space heater for load.1st 30 min run: 15 min no load 15 min space heater on low. Change oil.2nd 2 hour run: alternate space heater every 10-15 min; low, high, off, low, high off. Change oil while warm, Let completely cool.3rd 2 hour run: alternate every 30 min; low, high off with space heater. Let cool completely, change oil.4th, 5th and 6th are the same as 3rd but you don't need to change oil in-between, just let engine completely cool between.*After 6th change to synthetic oil run it under high load for 15, 20 min and change oil again with synthetic. To flush out all the break-in oil.This process allows proper ring and valve seating at all the temperature ranges and clears out the massive amount of metal shavings you get with break-in before they cause issue.After break in re-adjust your valve lash and check every 100 hours or so after it every other season.Use non ethanol gas run empty when not going to use it for a month. Put fuel stabilizer in any gas not used within a month and at the end of season pour that gas in your car and use fresh gas next year.These little Honda clone engines will live a very long time if properly maintained but die fast if not. Overall it's a great value being less then half the price as name brands.Break-in oil used: Royal purple engine break in oil.Regular oil: Briggs and Stratton 4t racing oil (best small engine oil on market)

Great idea but think long and hard before buying one! What a great idea but horrible implementation. First off the App is so wonky you will go crazy trying to get it to work. It works then it doesn't and when they update the app you go through crazy attempts and reinstalls that just don't work. The real issue is the battery used for the starting... when it goes dead and it will... you CANNOT start the generator NOT EVEN WITH THE PULL CORD. They have some type of electronic choke that need the battery! I had to take the genrator apart, find the battery (good luck) disconnect the propane hoses to squeeze it out and then jump start the generator with a 12 volt battery... and wait for it... there are no replacement batteries availible... don't believe me... just try to find one. DO NOT BUY THIS GENERATOR UNTIL THE COMPANY FIXES THE APP AND MAKES A BATTERY AVAILBLE.

So far so good. I bought this because of the longevity of reviews on their products and I am pleased with performance thus far. Out of the box, it looks nice. My wife even liked the coloration (big win). for initial break-in, i chose Pennzoil traditional 10w-30. Filled with Non Ethanol 89 gas. took more pulls than I expected but backing off the bowl drain ensured that it had fuel in the carb and it fired right up. Initial bluetooth connection was wonky, but once connected, it worked decently. I wish i could see RPM in the app but the wattage readout is nice. Cycled it with the eco mode off with no load, then 800 watts, then stepped it up to the max I wanted it to run at. Hooked it to my 2013 Keystone and ran the AC. I believe it is a 13.5k BTU unit. spiked at 3200 and then leveled off at 1900 watts with the AC and Fridge running. PERFECT. Got about 4 hours of total run time cycling between the 1900 watt load and 300 watt load for 30 minutes each across one evening and then the next morning. Changed the oil and you could absolutely see the glittery break-in present in the oil. Refilled, Idled it a bit and put it away. one thing that caught me off guard is the shut down procedure. it will lower the RPM and then it almost sounded like it dieseled for a bit, but I think this is some sort of short purge it does as it did it consistently every time.It handled the load perfectly but at that load, it will use 20% of the fuel in 30 minutes. I will likely invest in that 12v pump to add a 5 gallon tank to it.why only 4 stars you ask? There was this loud vibration sound coming from the front of the unit. I could push down on the red panel and it would stop. Something was not tight in it. I ended up taking off the front panel and found that because of the plastic mounts that hold the inverter heat sink were not stable, it caused it to rattle against the front panel. it left some easy marks so I ended up applying a little double sided rubberized 3M tape to the red panel insides (left one side with the protective film on) and this solved the rattle. It was super easy to do though.Panels are easily removeable and this item looks very serviceable. I plan to give it 4 more hours with conventional oil and then swap to synthetic.

The inverter-generator is pretty much as advertised. We have used in on Propane only, in order to keep the engine gunk-free. So far we have not tested at high altitude, but at 3,000 ft where we live, it operates very well. Highly recommend watching a few YouTube videos about the unit, to save time and to clarify operating and set-up instructions (for instance, it's important to connect the battery wires properly before starting it. We did everything as suggested and it started up the first time (push-button) on propane only. According to one video, if using propane, it's helpful to close the spark plug gap just a teeny bit. But getting the spark plug out with the tool that comes with the generator was not possible. It was a flimsy socket tool that stripped (the plug stayed fine). Went to the auto-parts store and purchased a spark plug removal extender socket for about $12. This on the end of my socket wrench worked perfectly -- plenty of leverage and a tight fit that made plug removal easy. The propane adaptor works great, and the generator ran our RV airconditoner (3,500 watt) perfectly. The ONLY thing that we noticed (so far) is that the noise level is not as quiet as advertised. It's not horrible, but it's not as quiet as 53-55 db. At 20 feet away, it's more like 63-65 db. Still very good, but more than advertised. Other than that, it's a great deal for the money -- portable, realt4ively quiet, good power output, versatile and not too heavy (53 lbs, plus it is on wheels). A this point, would highly recommend.

Impressive, decent quality, somewhat light, filled with oil started easily on second pull 13 degrees! surprisingly quiet also, time will tell how worthy but initially I’m impressed!Update, it’s a piece of crap! It’s never been used, stored inside, gas with fuel stabilizer, started frequently, but this time it’s struggling to run!Only been three months and never used, I’d say it’s unreliable!

this small but powerfgul generatos kept running for a whole week with no issues ever. I loved it, just wished we could have gotten the newer version with both gasoline and propane for a wider functionality.

Excelente producto, espero será Excelente servicio

This portable generator was absolutely worth the investment. During the recent ice storm, we lost power for an extended period, and this generator saved approximately $500 worth of frozen food from spoiling. It started reliably, ran consistently, and gave us real peace of mind during a stressful situation.It was easy to use, reasonably quiet for a generator, and handled the load without any issues. Having dependable backup power made a huge difference for our family. I would definitely recommend it to anyone looking for emergency preparedness or backup power during severe weather. Got it on special and it already paid for itself

The MXR2400GT runs fine as a generator, no issue there. But the Bluetooth feature simply does not work as advertised. Even when it does connect, all it shows is the remaining fuel level — no generator status, no load information, nothing else that the app is supposed to provide. Basically useless.I contacted support about it, and instead of fixing it or offering a proper replacement, they offered me $50 to just keep the unit as-is. They kept insisting "the generator works fine," completely dodging the actual issue — the Bluetooth/app feature, which is advertised as part of the product, doesn't deliver what it promises.It's frankly ridiculous to be offered money to accept a defective feature instead of getting it repaired or replaced. If Bluetooth monitoring matters to you (a big selling point of this model), be aware it may only show fuel level and nothing more — don't expect real support if you run into the same issue.Amazon refund the whole scrap.

I don't EVER leave 5 star reviews. Perfection is unattainable. But this little genny just impressed the heck out of me.I bought this unit 06 Nov 2022 as an emergency backup to my emergency 200AH battery and solar system. On receipt I filled it with the best synthetic oil available and cranked it 2 dozen times to cycle some oil through it. I checked the spark plug gap and then fogged the cylinder with oil so it wouldn't rust inside itself during storage. went over the startup procedure with my family and then put the cover on and hid it in a corner near the patio door where it sat for a year.We just had a huge fall storm come in this weekend but we got by with no outages. But that kicked me to test it fully for once.I had less than 1L of fuel from my lawnmower jug. On choke it started on 3rd pull. Right away turned from choke to run and the idle (on ECO) settled perfectly and totally smooth.Ran it on Eco (1/2 RPM) for 40 mins with no load waiting for wife to get ready for work.I then flipped my mains off, turned ECO off which increased speed to max and then plugged it in to power one side of my breaker box. DO NOT attempt this yourself!! You could kill a linesman or yourself!The engine speed dropped just the slightest bit on plug-in because I flipped almost everything off first including furnace. I went around turning circuits back on and was very pleased to find both fridge and furnace powered on the same side of breaker box. Everything ran great, lights, fridge, furnace.I then switched to ECO mode and the engine speed (and noise) dropped by half!! What!! With a load on!Occasionally when the fridge compressor kicked in, or furnace motor fired up, my LED light fixtures would dim for a half second or so but the genny reacted very quickly and promptly idled up to meet the draw that was put on it. My 60" TV did not even react. Nor did anything else I noticed.Engine speed seemed to increase a bit now and then when I didn't think an inductive load had cut in, but it still ran solid and kept us powered up.I think it ran almost 3 hours total with both load and no load on less than 1L of fuel. The ECO mode works incredibly well in dropping the engine speed and then ramps up to meet the load requirements.I'm changing the oil tomorrow and installing a magnetic drain plug which every small engine should have to prolong life.This unit meets all my needs and passed my tests. I should be able to rely on this for many years.

On initial start, very easy to set up and start. APP seems to be connecting and working as described. Nice, compact and quiet. Took a moment or 2 to figure out how to remove the panel to access add the oil for initial start up. Directions are not crystal clear. Otherwise I like the whole concept. I also like the 3 adapters.
