  • good generator for home back up
I got this for my home as a back up and other future projects. Just put 5 hr. and test how it will work with my home. It runs almost everything can run the central AC 3 ton and the well pump at the same time , you have to keep in mind to prioritize the equipment that you need. It can't run all at the same time but if I turn the AC of I can turn on the water heater and well pump and take a hot shower. Will recommend. Pros: Low noise, Powerful, Easy to start, easy to perform oil change Cons: heavy, Can be difficult to transport ... show more

  • Just got the delivery
This is my initial review. Got the delivery yesterday after 2 weeks. The communication was through email for the delivery. I was very impressed with the packaging, it had wood on top and bottom and very well protected. After opening I put the oil in and connected the battery, connected LP gas and it started right away. I texted several tools and started the brake in process. So far very happy with this generator. I had order a magnetic plug for the oil but the new version as already a magnetic at the tip of the oil stick. I was a little scared buying this brand, but so far I am impressed with the quality, features and attention to detail by this company. I hope I continue to enjoy this Genmax for years to come. ... show more

  • A Very Nice Generator
After weeks of frustration with the shipper, the GENMAX gm10500ietc generator finally was delivered. The delivery itself went quick and easy. Thumbs up to the delivery team. Getting the shipper to actually make the delivery is where the frustration came from. Word of advice to buyers; once the item has made it to the local distribution hub/last mile delivery point, be proactive on scheduling delivery, don't wait for them to call. Once I called and scheduled delivery, I had the item within a few days. Now to the generator: The GENMAX gm10500ietc was very well packaged and the generator was delivered undamaged. After unpacking, saw lacking was a User Manual. Reached out to GENMAXservice via email and got a reply within a few hours basically saying GENMAX has gone paperless (whether or not this is true, I'd like to hear from other reviewers in this regards) and the User Manual can be viewed online. If I wanted a printed User Manual, they'll send one out after providing proof-of-purchase, serial number and address, So, thumbs up to GENMAXservice for their prompt reply and willingness to sending out a User Manual. Also worth noting: the generator also did not come with the assorted plugs as seen in the listing or viewed in some unboxing videos which is okay. By the time you purchased a length of cord to use with the plugs, you could just as well purchase a premade cord ready to use out of the box. Did come with a quart of 10w30 motor oil tho, which I found surprising. For those wanting to know, the unit did come with a magnetic tipped dipstick so no need purchasing an after-market. After adding oil, connecting the battery and hooking up generator to propane, the generator fired right up. For break-in, ran the gm10500ietc for 2 hours with a couple of space heaters connected to the 30 amp/240 outlet, varying the load, with ECO mode on or off, heat gun plugged into the gfi outlets, the generator didn't miss a beat. Ran smoothly, rpm increased/decreased as the demand increased/decreased. First used the push button to start/shut down and then tried the remote. Remote worked perfectly. Did not need to add batteries or pair up the device. After running for 2 hours, weighed the 40# propane tank, did the math and came up with 3 lbs was used in that time. Still have some more break-in time to do before first oil change. So far, with the GENMAX gm10500ietc, everything is looking good and am confident I'll get many years of use. Went with 4 stars and not 5 due to the frustration experienced with delivery. If I could go with half stars, would of went 4 1/2 out of 5. It wasn't what I was expecting. Guess I'm too used to Amazon delivery going flawless nearly everytime. ... show more

  • Awesome
This generator is very quiet and after connecting it up to the natural gas line, filling it with oil (ONLY thing I wished they included in the box) it did not take long to fire up. It did turn over several times, to be expected, but then it ran perfectly. I have not yet connected it to my house, need to get that wiring done - but it's set up for now. What impressed me was that it came with the quick connect pipe and the extra loose fitting that I needed for the connection to the main line - and for that, I give this the 5th star. The seller did a great job, making sure (expect for the oil) that you could fire this up, out of the box. I had to drive to a store to buy the oil - but not a big deal. My suggestion to the seller will be to ADD a sealed bottle (quart) of oil. Some customers may not have the oil on hand and have to drive some distance to get the specific oil. Overall, I recommend the generator and the seller. Super chuffed that I bought it. ... show more

  • Defective unit.
Quick delivery after purchase. Inspection after unboxing was OK but noted 2 hrs on display and no owners manual. Filled oil & connected battery and full LPG tank. After start and ~10 minutes @ low idle to warm up I started adding different loads (lights, small appliances, refrig, freezer, etc). All was good for ~ 1 hr when generator would severely bog then surge when a refrig or freezer compressor would start from a base generator load of 600w to 700w. It did this with low idle switch ON or OFF. With switch OFF the surge would stop output with OVERLOAD warning light illuminating. Reset was normal, but after 5 such events I disconnected and shut down the generator. Too much potential damage to computer and appliances. Unsatisfactory performance from this unit. Now awaiting refund. ... show more
