4000 Watt Inverter Generator, Bluetooth® App Data Monitor | Portable Gas Powered Generaator Remote Data Check RV Ready, with CO Alarm for Outdoor Camping, Home Backup,MXR4000

Update 7/14/2026: After using this thing for almost a couple years, I can honestly say it was a great purchase. Even after storage, we checked the fluid levels and it started right up with no issues. Updated the review to five stars to reflect this. During testing, the generator was able to maintain 3100-3150w without hesitation for the entire gas cycle and handled peak loads up to 3900w just fine. We did not test past 3900w. The app is useful for monitoring and matched the digital display and actual consumption measured from the outlets. Conforms great too for lower continuous pull and is noticeably quieter and increase fuel load run time. Strongly recommend. Initial Review: We purchased this generator in time for hurricane Milton and we thought we were sitting well. Generator turned on. Ran for about a minute. And turned back off. We reached out to the maker and they were able to assist with a quick repair. Everything is working and they were able to provide compensation to make it right. Good company. Good products. Would buy again and recommend.

For the money and technology, you can’t go wrong. So far 20 hours with no problems change the oil twice so far. It’s a little powerhouse and weighs only 50 pounds add a medium load. You will get approximately four hours form the 1 gallon the gas tank.

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.

Seen a review on YouTube and he was raving about it, well he wasn't wrong! It ran with very little effort, it isn't as loud as you would think, it is a MUST buy!

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.

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!

Works amazing super quiet. Easy to put together out of box. Great value for the money! It's small and light weight but very powerful. Did my camper with ac blasting and microwave on and didnt have a problem at all

We have a camper out on vacant land and this generator is perfect. It has enough power to run our entire camper and is super quiet and easy to operate. Great price too! 😊

Excelente producto, espero será Excelente servicio

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.

This generator is an absolute steal. I was hesitant reading some of the reviews. It came extremely well packaged and after adding oil and gas fired right up in 3 pulls on the first start. Has started first pull every time after that. Easy enough for my wife and 8 year old to pull and start. Powered our RV AC, toaster and coffee pot simultaneously. My only complaint would be the fuel tank size. Running the AC in 33°C the tank lasted roughly 3 hours. For those getting a CO warning right away. Make sure when filling the oil for the first time to move the O2 and CO sensor hoses back to the fresh air opening in the cover. Also do not cut the zip ties holding these or replace them if you did. After looking into a lot of the posts saying it ran once then stopped after a while and won't start. These do not come with oil in them. You need to add oil and make sure to do a change after break in. A lot of the posts here are cross posted in reddit and people have been running them without oil and then wondering why they won't start again.

Been using this for 3 months and it runs great

Love it
