(Updated review:) I am changing my review to 5 stars as after correspondence with MaxpeedingRods and going through their checks they have stood up and done what’s right and stood behind their product by replacing our Generator. I believe that there was a fluke issue with the original one and it originally worked 100% only to later loose the electronic start function. I have no reason to believe that this is a systemic issue and think that it was just our luck of the draw to have that issue. The new generator works flawlessly. When a company like MaxpeedingRods stands behind their product we can tell that they are a company that we would like to continue to do business with and recommend their products to our family and friends. For full disclosure I paid for the first generator out of pocket full price and with the issue and going through their resolution they replaced it. Knowing this you can feel safe in spending money with them for an investment such as this. Thank you MaxpeedingRods! (Original review for reference:) I am going to say it’s a wonderful product with at this point questionable support. I am going through their support for the last week with limited effective responses. If this changes I will change my review to 5 stars but at this point the electric start has failed and they are sending me thru the same tests multiple times. When it arrived everything worked flawlessly and now only the electronic start functions do not work and I eagerly want a resolution but so far I’m just getting scripted responses from the app at first and now via email. If they help me resolve this it will truly be a quality generator however the support has to stand up and provide true assistance for this to happen. I believe they can if they are willing. (Final thoughts) as you can tell if you read everything they did stand behind their product and I once again commend them for it.

Started great, good looking machine, remote start is awesome. Now the bad, after putting in new oil and hooking it to a brand new freshly filled 30lb LP cylinder the generator ran good for 20 minutes and then shut off on its own. Now it shuts off after less than a minute of running every time. Flashes a C02 or maintenance light once and shuts down. It's outside, so a C02 issue is non-existent. Im talking to the manufacturer through their app, slow responses but promising to "send me parts" the last thing I want to do is tear apart a brand new generator to fix a factory lemon. I bought this for an ice fishing trip and I leave this week, now I'm in a bind. Don't buy this unless you want to be frustrated and work on a brand new machine after 20 minutes of idle time.

As a bare generator it worked well. Powered my 12k BTU portable AC, fridge, some electronics and a blower fan with a 20lb propane tank for over 12 hours no hiccups. The major issue was complete loss of bluetooth functionality, the app and even the onboard lcd screen displaying usage % etc. This left me in a bit of a limbo with hurricane beryl as I wasn’t sure how it would fare overnight. Luckily we got power back in 16 hours. I seriously needed bluetooth to monitor it from the other side of the house while it was on the front porch. It was never exposed to any rain. I emailed [email protected] and exchanged 4 emails. One asked to send them a video of the unit not displaying the bluetooth LED which I did. After that I was told to wait 1-2 business days and one week later I have still not heard a response. Even with the $200 coupon this unit sits at a pricey $899. At that price point the main reason I purchased it was limited availability of other bluetooth-enabled generators. Really you are limited to this one, the MXR4000, Honda 2200i, Ecoflo and Ryobi. Apart from the other MXR none of them are rated for more than 3000 watts. So I bought this one. Now if bluetooth is unreliable and nonfunctional, at $899 you can most definitely proceed with buying a much more powerful inverter generator lacking bluetooth well within 6000W territory. I will update the review and rating once I hear a final usable solution from MXR. For now, I find 3 stars generous simply as it kept us reasonably comfortable with a cold fridge for 14 hours (which one can argue any number of other generators could have done and more at $899).. UPDATE: Customer service was generous in offering a partial refund for the bluetooth malfunction to be used towards the bluetooth surge plug. Happy with their service, increased to 5 stars. They offered to replace it but since it functions as a regular generator I opted for a bluetooth plug and only lose the remote start capability which is fine

First a quick tip: If you are getting rough running on gasoline, particularly with lighter loads (around 1000watts), replace the spark plug with an NGK CR5HSB and gap it to the manual specified .032 (.8mm). It seems these generators are being shipped with the gap set much tighter than is specified in the manual, probably because they run better on propane that way. Now on to my long winded parts concern: I’m giving three stars as I find the generator to be of decent quality and the features are top-notch. I know of no other generator currently on the market that provides this much power at this size and weight and includes so many features like electric start and remote start with Bluetooth. That’s the good, and that’s not trivial, but here’s my story to explain the bad and that bad might be a deal breaker for some people. This is long, so feel free to skip to the end for the wrap up. First, I have been a small engine mechanic for the past 15 years. I have a shop in Maryland that repairs and maintains lawn and garden equipment, motorcycles, scooters, generators and outboards. When my unit arrived, I unboxed it, filled it with oil and started it up without a load for an hour and it ran flawlessly. I played with the Bluetooth function and was truly excited to realize that I would be able to start and stop the generator from the comfort of my RV without having to put on clothes. :-) For the second hour, I added about a ¼ load using a heat gun set to its lowest setting. I then did an oil change. On day two I went to try to start it using Bluetooth and the generator could not be found on the app. Checking the generator I found that the Bluetooth LED was not lit. I went through the procedure to turn Bluetooth on and nothing happened. Thinking I must be doing something wrong, I went ahead and started it up and let it run for two more hours under varying loads. During that time I was never able to get the Bluetooth to turn back on. (The procedure is to push and hold the reset button down for a few seconds.) I did another oil change and when I went to start it up again the battery was dead. This made no sense as it had just been running for two hours with only about a 10 minute break to change the oil. I disconnected the battery and checked the voltage and it was only at about 9 volts. I connected a lithium charger set to 2 amps and charged the battery back up to 14.4 volts. Reconnected the battery and started the generator up again. Now I connected a multimeter to the battery while the unit was running in fast idle and I could watch the battery slowly discharge when it should have been charging back up after the starter had drained it a bit. My first thought was that there must be a problem with the DC regulator, so a disconnected it and found that it was actually producing 14.4 volts when disconnected, so it was fine. But when reconnected it would only output 1.5 volts, which is definitely not fine. Looking at the schematic that is included in the manual, I saw that the next component in line after the regulator was a PTC (resettable fuse) so I found that and tested it and it was also right where it should be at <1 ohm. Next in line on the schematic is the USB port. I tested the port and got zero volts output while the engine was running. I disconnected the USB port and immediately the battery started charging at 14.4 volts. So, the USB port is bad. I don’t care as I would never use that anyway. ( I would have much preferred a 12 volt port there instead.) So I could just leave the USB port disconnected and the battery charging problem was solved. But none of that explained or helped the Bluetooth problem. The schematic is not very detailed so locating the Bluetooth module is not simple. There is a block labeled “Bluetooth Display Meter” on the schematic that I found on the machine that appears to provide the variable display, and several LED indicators including the Bluetooth indicator. This being the only mention of Bluetooth on the schematic, I’m guessing that it also is the location of the Bluetooth module. (I suppose it could be integrated into the inverter assembly, but that doesn’t seem logical to me.) So something had happened that took out the USB port and the Bluetooth module. What happened, I don’t know, but I made the decision that I wanted to return the thing, either for an exchange or for a refund as the problems occurred withing 24 hours of opening the box. I thought an exchange would be fine as my experience must be a fluke based on all the positive reviews. And I really do like the generator otherwise. As we all know, you can’t return items that include gasoline engines using the normal Amazon return procedure. I tired, of course, but got the “this item is not returnable” message. So I called the number included in the box for support. I got a very friendly fellow who really wanted to help. He tried for about a half hour but concluded that since the generator had been shipped from an Amazon warehouse, he could not arrange a return. He was not a technician, so he couldn’t help with any further troubleshooting either. He sent me an email with the phone number for Amazon support saying they were the only ones who could arrange a return/refund/replacement. His email also instructed me to make and send them a video showing the issue. So I did that first, sending a video that showed that the engine would start and run but that no matter how much I tied, the Bluetooth would not turn on. I then called Amazon who, of course, told me that the generator was not returnable and that I should contact the manufacturer for warranty service. I explained that I had done that and the manufacturer had sent me back to Amazon. It took 40 minutes on the phone talking to two different but very friendly and helpful reps, but the end result was they sent me a 100% refund and told me to keep the unit. Nice! For full transparency here, I will say that I then immediately ordered another MXR4000GT, but this time on one of the big box store websites just in case I ever needed to return the second one, the process would be very easy as it can just be taken to any of their stores. I did lose about $150 on the transaction as my purchase on Amazon was using the Black Friday sale pricing, but oh well. So now I have a free MXR4000GT without USB (I don’t care) and without Bluetooth (I’d really like to fix.) So I waited to hear from Maxpeedingrods support regarding the video I had sent. I have already bored you enough with detail so I’ll spare you the detail of a weeks’ worth of emails back and forth between me and China. It was exactly the same as any other time I have dealt with China for product support. Each email takes 24 hours to get a response (Understandable. They’re on the other side of the world.) and it always appears that each email is coming from a different rep that never bothered to read any of the previous emails, only the one they are responding to. It can be very frustrating. Suffice it to say I just kept explaining that I am a small engine mechanic (they all wanted me to take it to one of those) and that I wasn’t asking for any warranty service, I just wanted to purchase a part. Specifically the “Bluetooth Display Meter”. This request obviously fell well outside of the script they use to answer questions so getting a rep that would finally answer it was not easy. But if finally happened and here are the last email exchanges: Maxpeedingrods: Dear customer， We sincerely apologize, but the spare part you requested is out of stock, and we're unable to source it at this time. Me: Will there be availability of this part in the future or are you saying that spare parts will not be available for this generator at all? Maxpeedingrods: Dear customer， Unfortunately, we're unsure when this spare part will be back in stock. We only have the whole unit in stock now. Thank you so much for your patience and understanding. There you have it folks, direct from the manufacturer. The only thing they have to sell is the generator itself. No parts. So what happens when your two year warranty expires? And have you read the warranty? Did you you notice that it specifically excludes shipping in either direction for this almost 60 pound item? Even if you find a local mechanic that is willing to work on it, they won’t have a source for any OEM parts so anything specific to this unit (like a Bluetooth module) will be a no go. Am I complaining? No, I ended up with an extra functional generator for $150. But I wouldn’t have purchased the first one if I knew there was no way to get OEM parts.

This is by far my favorite generator that I own (out of four). I use it to charge my solar home backup batteries when solar isn't cutting it. The app works well and the output THD is clean. It's a little louder than my generac iq3500, but the fact that it runs on propane more than compensates for that. I also like that I can pick it up and set it in the back of my truck and use it to power my welder anywhere I go. The build quality is great and is very efficient on propane. I get between 6 and 8 hours on a 20lb tank with moderate use. It's also great for camping when solar isn't enough to power my tent AC. I've also seen several people using them for RV's and they really like them. I also like the fact that they put a light on it. The display tells you all the info you need if you don't want to use the app. I usually don't push it past 2800 watts but it will surge to 3600 watts on propane if needed. I did swap out the spark plug it came with (torch) with an NGK plug. I haven't and don't plan on putting any gasoline in this generator, so I can't speak to it's performance on gas. Another perk to the design of this thing is the internal propane regulator, so I can use any propane hose that I want and not have to worry about an external regulator that other brands require that can break, be left behind, or misplaced. You still have to use a tank regulator, but not the big plastic/metal one that champion and predator come with. It also comes with a parallel kit if you want to combine two of these. I would definitely recommend this generator for any light duty single phase power needs.

Still in break-in so will see long term. Good so far. Fired right up on propane with electric start. Encountered issue of CO flashing yellow light and shut down after a couple of hours. Contacted support and got a quick diagnosis. Think it overheated while running in Texas heat. No problem after cooling and restart while running in shade. Unit is fairly quiet. 58 db at 50 feet at 50% load. Blue tooth is functional. I especially like th ability to report issues on the app. Nice feature. Happy camper so far.
