Good little generator. Can run my rv air and microwave and tv at the same time. So it will easily Handel the air a few other things with out over working. I only have about 8 hours on it so far but it has worked great. Make sure to run it a half hour and change oil. I then ran an hour at a little heavier load and changed it again. Glad I waited buying it when I first seen it because I payed considerably less at sams club.

5 stars so far. I bought this generator because its size meets my needs, not my pocketbook. I currently have 85+ hours on it so far. The pros so far meet all my needs versus the cons. If you buy a generator to run it at the max running watts, you're buying too small and will be unhappy with noise and performance. Pros: -The weight (about 60lbs), I'm 55 and picking up the predator 3500 or 5000 (over 100 lbs)is finally too heavy for me to be picking up by myself to put in the back of my 4x4 dually. Genmax also makes an external fuel pump I'm purchasing, plus a 6 gallon boat fuel tank to give me about 7 1/2 gallons of fuel for 20 to 30 hours of run time. 6 gallons of fuel weighs about 50 lbs, so I'll appreciate having those separate for transportation. -The remote start/stop works as it should. -Same for the push button start. -Pull start works as well, but I was not able to pull start with battery disconnected (5 tries), but it's fuel injected and needs power to pressurize the fuel. -easily runs my rv 13.5k a/c (no softstart installed) at 1600 watts, and it's just as quiet as my predator 3500. No problems with a/c, tv, lights, and microwave running at the same time. Cons: - So far, the only con on these newer generators is the co sensors (all makes and models, tons of YouTube videos on this subject) . On our in the machine is the worst place possible to mount these. If the government requires this feature, it should come separate for you to take inside where it matters. I could easily point the generator at an open window and suffocate without it ever shutting down. My co sensor new out of the wouldn't let it run more than 7 minutes. I emailed Genmax (took 2 emails) to get them all the info they needed. It takes them about 3 business days to respond to an email. I'm my case it 8 to 10 days before I received a message my new co has shipped. Parts in hand 14+ days after 1st communication by email. Calling for service seems to be a thing of the past if you want someone who speaks English as a first language. This is why I chose the email route. Other notes, I did call Genmax a year earlier before purchase (yes, I'm slow with purchases like this) and was able to talk to their service department (Around 11/11/2023) and actually got an English speaking person in California. I questioned this model 4800 over the 4600 they sell at other retailers, and I was assured it could handle the 4800 starting watts and that parts are accessible. I wasn't able to plug enough in to reach or exceed 4800 watts. Final thoughts: I'm extremely happy with my purchase so far. How long will the electronics work with the fuel injections? Who knows....

I bought this unit after my Champion generator took a dump on me. Just wanted to say this unit has been nothing short of Amazing! It has the necessary outlets and not the typical over complicated amount, as well as extremely portable! Good Job Genmax!

I purchased the GENMAX 4000 iA knowing that I needed to have a powerful, reliable and easy to move unit that could handle operating several things in my house if we ever had a power outage. I am glad that I made this purchase because an ice storm took out our power for 4 days. I set this unit up quickly to run temporary heat and lights, and it handled everything for the entire outage. Super quiet when it was in low idle mode and extremely strong when something demanded power. It ran about 6 Hrs. under heavy load with a full tank of gas. It started back up immediately after refueling with one pull, no problems! The weather was about 12 degrees Fahrenheit, day and night and the GENMAX was perfect! I have owned and operated many generators; this brand is incredible. If you need a small self-enclosed generator, get this product! It’s absolutely worth the money and built incredibly well. Strong, quiet and lightweight! Starting is so easy, which was important to me as well.

In all honesty I was afraid to buy a gas pressure washer- I wanted electric just for some home diy projects like my garage floor. The price on this was unbeatable and so I bit the bullet and bought it. This works perfect and it’s super easy to set up and maneuver. I can’t say I’ll ever go back to a electric pressure washer as I really feel this unit will last the rest of my life time. It’s strong and I called their support cuz I broke my wand and it cracked. I had a replacement at my door step 4 days later. Great company, better product. Kudos to genmax

Bought this Genmax 5500watt generator as a backup for power outages, and it has done exactly what I needed. Assembly was quick, and it fired up easily after adding oil and gas. I was able to run my refrigerator, freezer, lights, Wi-Fi, and a few outlets without any issues.

My wife gave me this as a Christmas gift and I just used it this week camping. I appreciate the durability this generator has. Was able to put it to use this week and I couldn’t be happier. Only thing I would say is that it is a little heavier compared to some other ones I’ve previously owned.

Fuel efficiency is impressive I got several hours of run time on a single tank, and the noise level is surprisingly manageable compared to other generators in this class. The outlets are conveniently placed and include both 120 V and 240 V options, which made hooking up my tools and home circuits easy.

This is great bang for buck buy, I don’t see anything else on the market that gives you more for your dollar than this pressure washer. I’ve had it for about 3 months now, broke the nozzle after a little bit , got a hold of the aupprt and they sent me all 5 nozzles again. No complaints

I bought this generator and it had a faulty CO sensor right out of the box. After numerous texts/calls to Genmax, I finally got a response back and they shipped me a new CO sensor which I installed myself. This is why I rated it only 3 stars. After getting the generator running, these are the pro/cons that I came up with: Pros: Seems like a decent generator Much lighter than the competition Easy starting and operating either with remote or manually Like the EFI as I operate it in various elevations Does have helpful customer support but quite slow to respond Like the telescopic handle for moving generator Control panel has lots of features Costs less than the competitors Cons: Does not have the power that it says it has. Will operate my 13500 air conditioner and microwave at the same time but it struggles Slow customer service Only 1 year warranty Seems to use more fuel than advertised A bit loud when under load I will do a follow up review after 1 years use
