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

My initial comments for the MXR2850 Generator. I bought this to run LED Hanger lights and a small air compressor. There is not a break in procedure in the manual so I used recommendations from internet. I filled with oil, started and ran it for 45 minutes with no load, then 15 minutes with varied loads 700 watts to 1500 watts. I then changed oil again and ran again for 1 hours with varying loads and changed the oil again. I plan to start using normally now. Pros: Arrived fast 2 days, clean undamaged carton, packed well, all tools and manuals included, new with no gas smell in tank and empty of oil. Cranks 1st time each time I have cranked it. Runs Smooth, engine speed varies with load. Handles different loads well, from slow for running 300 watts for 25 led lamps in my hanger to starting and running a harbor freight 7 amp air compressor, to a 1500 watt heater. This is much better than my Duramax XP2200is which had problems with the compressor. Very light for wattage rating, is lighter than my Duramax XP 2200is it is replacing. Digital read out to confirm volts and frequency, also keeps up with run time. Oil changes are easy, no tools, spark plug and air filter appear easy also Cons: It’s is NOT as quiet as expected or hoped for. It louder than other inverter generators I own, a Honda 2200 and my DuraMax 2200. The noise appears to be exhaust so this may not have as quiet of a muffler as the others. This would NOT be a good choice for a campground but works for me as I am just powering hanger lights and occasionally a grinding wheel or compressor. NA: I don’t know about long term performance or seller performance as it has been too soon but the generator packaging and initial impressions are good.

It is a very reliable generator and very quiet it gets the job done

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

Worked great until about 200hrs when it started hurnign oil and having idke issues. I did the breaknin procedure exactly as described in the manual and only run premium oil. Ive only had it for a few months, theres no warranty that i can find. Im Screwed out of $500 dollars.

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.

This is a great little generator. It weighs about the same as my Honda 2200 and yet puts up 4000 W instead of 2000 additionally, it powers my whole travel trailer, including both air conditioners. I love it. It is slightly more noisy than the smaller Honda, but the power is worth it.

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! 😊

Très bien emballé et fonctionne très bien !!!! Pour environ 30 heures d'utilisation jusqu'à maintenant j'ai aucun problème avec, elle démarre toujours très bien et est très économique, très satisfait, silencieuse aussi, très bon produit surtout pour le prix !!!👍👍

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.

Bought as an emergency back-up to charge batteries on cloudy days (solar set-up) ... I carefully read the reviews before buying, everybody was giving a go (4+ stars).. even watched reviews on youtube/net to have live reviews from real people ... ordered it, received it very fast (like next day!), followed start-up procedure, started second pull, everything went perfectly well, pushing more than enough power for my little charger (only needs about 500 watts) until the second time I tried to use it (first use was about 4 hours / half a tank)... It just didn't start .. again followed procedure, oil level fine, full of fresh new gasoline, spark plug does sparks and dry, (I'm a certified small engines mechanic) gas gets in the cylinder, but no matter what I do will not start - did not want to investigate further so the warranty doesn't get voided ) ... at least 100 pulls later, nothing ... tried to contact amazon and/or seller, they asked me to send picture/video of the thing not working (!) via an e-mail adress that Amazon gave me ... I did so, three times now, almost a month later and no news whatsoever ... yep, that thing is perfect for 1 shot, then you just throw it in the garbage ... now I'm buying another brand, should have done this first time ! please, don't buy !! you will get NO ANSWERS/RESPONSE from the company !!! 1 year warranty ??? don't think so ... Oh , btw, how can we give less than 1 star ? cause I would give 0.5 star for the fast shipping...

Good one. Last night power was out for 13 hours . I was able to run same time 2 small space heaters and freezer chest and fiber modem. Refill furl one time.

Just received mine today.staryed very easy after adding oil and fuel. Hopefully it last.where i live power goes a good bit.
