Hi Gavin. (Teacher). GenMax $1699. GXS7100iRD AiPower Costco$1299 and when on sale $999. AiPower THD Less than 3. Cleaner Sine wave (power). Protect your router/laptop/phone/ computer, it’s 2 THD less than GenMax’s is 5THD. AiPower has a Drain tube on bottom of Carburetor, easy to keep fuel fresh. The oil drain has a tube to drain oil easily with less mess. The fill funnel they give you is a great design also. AiPower when it runs on Propane and it runs out, it AUTOMATICALLY switches over to gas giving more run time. Put another full LPG tank on it and it switches over to propane immediately. (Propane is their priority fuel) GenMax LPG 6500/5500 AiPower LPG 6400/5100 GenMax 7250 Gas 7250/6000 AiPower 7100 Gas 7100/5700 Parallel ready. 50amp and 30amp plug. GenMax only 50amp plug. 322cc engine vs GenMax 312cc. LED Display is beautiful and has a led light on panel to see in the dark. When you tested it you said it was very quiet, it is 100% I agree Gavin. You didn’t even overload it in your great video. Would love to see them compete against each other. AiPower GXS7100iRD The price of $400 to $700 LESS oh my goodness. Check Compare to each other before you buy. $400-$700 difference in price. I had to go with the AiPower 7100. Well made, heavy duty Machine. Gavin please please do a side by side comparison. You are the Generator Man #1. Continue to help us make a wise decision and save us money at the same time. All the best health to you, fans and Family. A very Grateful follower. Mike ienuso
Nicely stated two very close generator both in price and options on paper. The AI power really looks good. I will do the test running the exact same load and see if we get an overload light on the AI power
Can you put your camera on your Sine Wave while turning on your A/C and let us know the Amps. it took while firing up. They say that when it switches from propane to Gasoline it stays at around 3THD’s. Even when it runs out of fuel it stays clean. I appreciate all you do. Can you try and do one more thing for me, get your Followers/Fans up to 1 Million Buddy!!! Talk/Text again soon. Enjoy your weekend. Mike ienuso
I just ordered the Genmax 7500 dual fuel electric start from Sam’s for $900 regular price. Looks like it’s the same running watts and has an additional 120V 30A plug. I’ll be using this as home back up for 1 fridge, 1 full size freezer, 75gal fish tank pump and light, tv, internet, fan, couple led lights and window unit 8-12k btu. Figuring out what A/C size I should get now. I can split my down stairs into 2 areas (living and kitchen or master)
Good video, debating on whole house generator Kohler RCA20 or a Generac air cooled 20kw natrual gas. Any suggestions or preferences on brand? Suggest a soft start for my 5 ton AC?
I’ve got a 2.5T unit. I’m guessing the GM7250 should run that just fine? I’m currently running a generac 6500/5500 open frame, but I’ve never tried to run my HVAC unit on it.
Thank you for sharing this test. Just got my Genmax 7250 today, thanks for your reviews and insights! Like this test, I’ll be using the 7250 to run a 3.5 ton a/c during an outage, and you just proved it can be done, even with a 5 ton a/c (with soft start). Gavin, did you have to convert the 7250 from bonded neutral to floating, since you have an interlock kit installed? If so, how did you do it? Do you have videos on the topic? Thanks again.
@@GeneratorReviewsHi Gavin, I started my Genmax for the first time last week and so far so good. Let it run for 45 minutes with minimal load, hair dryer and a small soldering iron. Today, I started it again and was successful. Let it run for 30 minutes then turned it off. When I tried to restart it again, it only cranked for a sec. So I took a voltage reading from the battery and only got 8.5v. Why was that? I got it restarted using the pull cord, but that was also a struggle. At least 6-10 pulls before it started. And then I heard rattling noise that sounded like it was coming from the pull cord winder. I removed the battery and charged it with my kayak battery charger for 30 minutes with 13.5v afterwards. Reinstalled the battery and started the generator successfully. Why wasn’t the generator charging the battery? Please advise. Thanks Gavin.
Hey Gavin, watching your content, I finally had an interlock installed at my panel with a 50 amp inlet last fall. Anyhow, I haven't gotten a generator yet, and I know you have a soft start on your 5 ton a/c unit. I'm getting a lot of differing info on soft starts. Here's my question, I have a carrier 2.5 ton a/c unit. With the right size invertor generator, do I even need a soft start ? Thx as always
Gavin that’s a great reply. So much easier on the Generator. Won’t have to work as hard. I would like to see it done using the AiPower GXS7100iRD so we can compare them. Especially that the AiPower is $400-$700 cheaper in price.
Your the best. Gavin Being that most of us don’t have a Sine Wave Monitor. Can you have that hooked up with your CAMERA “ON “THE MONITOR while you turn on your AC so we can see how the sine wave stays clean or varies. With GenMax less than 5 And AiPower less than 3. They are both very low yes. But you know what I mean, I’m sure you would prefer 3 over 5. Even when it switches over from Propane to Gasoline they say it still stays clean, even when it runs out of fuel. I’m not going to hold you to anything, but I would love to see these things done at your leisure Sir. All the best, Mike ienuso AiPower owner.
A soft start will absolutely reduce the stress on your generator every time it cycles. It will give you more wattage for other loads since the ac unit won't draw so much.
What are the differences between the sister machine Pulsar PGDA70BISCO which is also made by Dinking and the Genmax GM7250IEDC? The only differences I have noted so far are color, auto transfer switch plug, and 30 vs 50amp plug.
Gavin, I need a 240v generator in this range. The inverter has very mixed, mostly poor reviews in the last 5 months in 2023. What are your thoughts on reliability of the GM7250IEDC?
Most of the comments are from brand new owners of generators. The first time they run into an issue all bets are off. I think this is a great 240v Generator especially for its price and size with a 50 amp plug. If you decide to run off, Gas, just make sure to drain the carburetor before storing it.
Hi Gavin, Any issues with this powering your house with the neutral bonded to the frame? I have a similar panel setup but am not sure if I need a generator with a floating neutral to work safely.
Wait - why is the gen at 100% when the rated power spec is 6000W??? Even factoring in power factor that's nearly a kW less than rated? The meter on the gen agrees with your power box, 4.7kW. What gives? If I buy a gen rated for 6kW I should be able to run 6kW without it overloading.
Gavin just found this, looking for a remote start generator to connect to a renogy invertor charger solar panel system. Basically for the invertor charger to start a generator to charge the batteries if the solar panels are not getting enough sun to do the job. Would this do the job
I would have to say GenMax they’re the only brand that’s pushing the envelope right now. Fuel injected compact generators and oil filter on the large generators.
@@JaromMcallister for my little bit of anecdotal evidence, I would treat it the same like a modern fuel injection vehicle. Store it with fresh fuel with your favorite fuel stabilizer of choice and exercise it for 15 to 20 minutes at least once a month. During tropical cyclone season in my neck of the woods, I do that at least twice a month and practice a full load power transfer drill while I’m doing the exercise test.
So you don’t know where the low oil level is on this junk , trust me it’s junk 30 years master. Ase auto technician trust me it’s junk period..@@GeneratorReviews
Not 1 person knows where to tell me to look not the company not the fools in California at the so called service center not you unfortunately unbelievable @@GeneratorReviews
@GeneratorReviews I'm currently working with genmax on finding the wire to remove. Sending pics, but I can only pull the front panel off by and inch or 2, and its hard to show them. Wish they would show me how to do it. Without doing this it's sending 240 to one leg, caused a bunch of problems!
@GeneratorReviews genmax says it because of the bonded neutral, and that's why I'm getting wacky readings. They once I remove that white wire, which I don't know which one it is, I'll be good. I'm getting proper readings from the generator itself. Would happen to have a pic of the one that needs to be removed?
@@hoody2141 did you ever get it solved? The instructions on website were vague and from a different model/revision. They showed a blue jumper from neutral to ground on the 20amp GCFI outlet, but that doesn't exist on my 7250. There is a white jumper from neutral on the 50amp outlet going to the common ground bar. Genmax tech said thats the one to remove. He also said they don't include those instructions because there are different revisions for each model and don't wont average people doing it and want licensed electricians to do the modifications.
@@GeneratorReviews thanks for the reply! The dip stick looks happy, but I'll add a little more and see if the trend continues. I tried taking both side panels off tonight and it ran for over an hour without issue before I had to shut it down. However, restarting immediately it would NOT even attempt to turn over using the electric starter, but it did pull start.
First calculate your loads running watts that should tell you what size generator you need, you’ll need to calculate for 50% of your generators max output power.
@@GeneratorReviewsOh I agree the options are excellent, but 100% at the load it was carrying was not its max running watts it was under 6000 watts yet showed 100% load on the video, I would be curious to see how it does with the 7200 watt heater the Honda rated at 5500 watts running ran that unit over its starting watt rating of 7000 watts. as well fuel economy vs the Honda running the same load and fuel vs running time.
Another great review. Thanks.

Great video as always. Sorry for the short comment. Very busy today.
Thanks Tom
Excellent video. Soft start is necessary for that much of a load to start. Do you know when the higher power models will ship?.
As soon as you order it from me, I’ll get it to you usually within 3 to 5 days processing time
Gavin, thanks for another great video. That’s a nice Gen-set, quiet, smooth, my guess 🤔 it’s a great affordable alternative to Honda.
Did you turn your water heater off in the breaker box? I would think in Florida you would turn your water heater off during a power outage.
Yes I would definitely turn the water heater off if it was electric but my water heater is gas
Thanks for the test
Is this a bonded neutral generator, did you unbond it to work with your inlet set up
Good video, debating on whole house generator Kohler RCA20 or a Generac air cooled 20kw natrual gas. Any suggestions or preferences on brand? Suggest a soft start for my 5 ton AC?
I’ve got a 2.5T unit. I’m guessing the GM7250 should run that just fine? I’m currently running a generac 6500/5500 open frame, but I’ve never tried to run my HVAC unit on it.
The question is will it run 3 -15kw RV a/c units if they are turned on in a staggard sequence?
I think it’s possible but two AC would work great, especially if you plan on using other appliances.

The main difference is that the Genmax has a 50 amp plug and the Pulsar has a 30 amp
Was ur fridge connected also?
Fridge ceiling fan, lights, and one TV was connected
What magnetic dipstick fits this one. Just purchased one.
Gavin, What about two 7250's in parallel to run a 5-ton and all the other household items? Thanks!
That would work great 👍🏾

looked like you were pulling 15 amps on one leg and 24 on the other is that correct?
Hi Gavin, Any issues with this powering your house with the neutral bonded to the frame? I have a similar panel setup but am not sure if I need a generator with a floating neutral to work safely.
I haven’t seen any but I’ve heard of people saying that the gfi circuits can trip if it is bonded
@@GeneratorReviews its NEC to have only 1 neutral to ground bond.
Wait - why is the gen at 100% when the rated power spec is 6000W??? Even factoring in power factor that's nearly a kW less than rated? The meter on the gen agrees with your power box, 4.7kW. What gives? If I buy a gen rated for 6kW I should be able to run 6kW without it overloading.
Did you have to worry about grounding the generator if you are plugging the generator directly into the house via a transfer switch?
Grounding is a plus for lightning strikes, but the generators is already grounded through the grounding of your panel
@@GeneratorReviews lighting strikes? SHORTS.
GCFI breakers will not work correctly when you have more than 1 bonding point.
I would like to know the sound difference between this one and a 5500 champion inverter
I know what the meters say but tones is the things you cannot tell. The Genmax is a 4 stroke? If so it should have a much deeper sound?
Gavin just found this, looking for a remote start generator to connect to a renogy invertor charger solar panel system. Basically for the invertor charger to start a generator to charge the batteries if the solar panels are not getting enough sun to do the job. Would this do the job
Yes, this will absolutely do the job. It has enough power to charge your batteries.
If it would power the AC will it power a furnace
Yes that is correct 👍🏾
Hey Gavin do you think they will make this 7250 in tri fuel. Because if not ill going to buy this one today why its on sale what you think
I doubt that they will do that because it’s not a large enough size for whole home backup
Hard to choose
Is that 5 ton compressor more than 5500 Watts? My electric hot water heater is 5500 watts alone
Yes, that’s about exactly what the 5 ton AC compressor pulls when running
@GeneratorReviews can't decide on this one or the 9000. But don't want to overkill for no reason. But if I'm underpowered, I'd be disappointed
What is your preferred name brand of Generator?
I would have to say GenMax they’re the only brand that’s pushing the envelope right now. Fuel injected compact generators and oil filter on the large generators.
When I used to live off the grid I would run my Honda EU2200i until it was out of fuel. Does it hurt a fuel-injected engine to run out of fuel?
@@JaromMcallister for my little bit of anecdotal evidence, I would treat it the same like a modern fuel injection vehicle.

Can you do a sound test on this one vs the new efi 4500
Yes I will do that once I receive one for testing
Hey Gavin do you know the location for the low oil level sensor on this model 7250
