- Опубликовано: 22 сен 2022
- In this test I drained both generators completely out of gas then added only 32oz to each tank.
Let's see how long they will run with a 1000 watts load.
(HONDA EU7000)
The Honda EU7000iS is a quiet inverter generator with a rated wattage of 5500 W and a starting wattage of 7000 W.
The Honda EU7000iS houses a 389 cc Honda GX390 EFI OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5500W along with a peak wattage of 7000W. In addition, the device is parallel capable, can be linked to a similar or compatible unit for added power.
The inverter generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 52 dBA (just slightly more noisy than a quiet suburb). Moreover, to offer you even more convenience, the EU7000iS can also be remotely started (via the My Generator App).
The Electronic Fuel Injection (EFI) system enhances the engine's reliability, lowers fuel consumption, improves startup, reduces servicing, boosts stale fuel resistance, and offers better altitude adaptability.
With a full tank, the EU7000iS can operate for up to 16 hours (fuel consumption around 0.32 GPH), thanks to its fuel capacity of 5.1 gallons.
(POWERHORSE 7500I)
The Powerhorse 7500i is a quiet and powerful inverter generator with a rated wattage of 6500 W and a starting wattage of 7500 W.
The Powerhorse 7500i's engine, 420 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 6500W and reaches a peak wattage of 7500W. Moreover, since it is parallel capable (parallel kit(opens in a new tab) not included), its power may be increased if linked to a second compatible unit.
The inverter generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 55 dBA (just slightly more noisy than a conversation at home).
With a full tank, the 7500i can operate for up to 16 hours (fuel consumption around 0.41 GPH), thanks to its fuel capacity of 6.6 gallons.

Gavin you the man brother! You setup test we all learn something and see numerous options available…. Thank you Sir 👍🏿
Thanks Eroc
it’s my favorite thing to see return subscribers comments.
Great comparison test video. You do a wonderful job 👍. Thanks.
Thanks 😊
Gavin, great test/comparison 👍 - Love your no-nonsense ☝️ approach - You sir have a new subscriber.
I own the earlier (carbureted) Honda EM7000is. Purchased it in 2004 and have used the generator after several hurricanes 🌀 hit South Florida since then. Fortunately, we did not get hit this week in Miami by hurricane Ian.
Anyways, I am very happy with my Honda. It will run 14 hours on 5.1 gallon tank with all the connected 120v load in my home. I use a Cutler Hammer/Briggs & Stratton 7500 watt transfer switch to handle the load distribution. Back in 2004 the Honda cost me $3,500.
Thanks 🙏🏾 LP
These are forever generators, happy to hear you are safe from the hurricane 🌀
Thanks for watching and subscribing
Thank you for another great video !!
Yessir trying my best 🙏🏾💯
As always great video . I can’t click on a Gavin’s Garage video fast enough. Which do you prefer the carburetor or fuel injection inverter generators just curious
I think the fuel injection is definitely way more fuel efficient and delivers the power smoother. It may cost more upfront, but not having to deal with those carburetors. It’s just so so much less stressful.
Hi Gavin, I just subscribed and enjoy your videos, thank you. I like to get your thoughts on how to best stock up for fuel for a short-term and long-term power outage. I live in Florida, and we have both hurricanes and no name storms to contend with. I do not live in an evacuation zone and I'm fortunate to live in an area that is close to a hospital and underground power lines. This past hurricane experience, we did not lose power. But learn from the past and prepare for the future is what I always say. Thank you so much!
Hey Juan
Thanks for subscribing. I think the best way you should store fuel especially gas is having all your containers and your gas treatment ready.
Usually when a storm is coming, we usually have a week in advance warning that’s when I store my fuel.
Propane has a 20 to 30 year shelf life so you don’t have to worry about storing propane.
Always store your generator, completely free of gas.
That's Honda for ya . Worth every penny. Yes...I would like to see you use the mini vac for fuel refills and emptying. Thank you. Great video too.
Small engine so... ya less fuel consumption. A accurate test would be comparing them at 75%-100%
I use a 6 gallon steel boat outboard motor tank with a nozzle valve and primer bulb to fill my portable equipment. The nozzle looks like a miniature gas station nozzle. The tank has a vent valve in the sealed gas cap. It stays primed after initial priming so all you do is put the tank above the device and let gravity do the pumping.
I think Honda. Also, I'd l9ve to see a video of how you store your generators. Thanks buddy.
Scott 👍🏾👊🏾💯👌🏾Yessir
Good review!!!
Another excellent video, thank you.
Thanks 🙏🏾
Excellent test. Thanks Bro..👍👍👍
Welcome 👍
Please make a video of you using your Mityvac to prep your generators for storage. Thanks!
Thank you for the video. Well done
Thanks
Good test. Thank you
👊🏾👍🏾👌🏾💯😎
Thanks
Would,d love to see the video of using the gas evacuator!
Neat video!!!
Also! Can you plug-in a 3prong adapter to the Honda and add the meter?
Awesome video my friend I love the Honda
Great test! I think 1000W was a good light load for this experiment, as it really shows how the fuel injection burns less fuel. The fact that the Honda ran about 50% longer is amazing! Not only are you saving fuel, but the emissions are probably much less (less unburned fuel) and the engine is burning cleaner with less carbon buildup, so longer life. It's still amazing to me, how much bigger in size, the Powerhorse is than the Honda. And the Honda is big!
Agreed!!! Maybe not quite 50% longer but I’ll give you 30%😅 yes, the powerhorse is a lot bigger
Thanks Tristan 👍🏾👊🏾💯
Much more expensive repairs carbs are 25 dollars on Amazon.
@@avadeal345 While I have had good luck with cheap $25 carbs for small equipment, I would not put a $25 carb on my $4500 Honda EU6500.
Need to compare prices as well. The Honda purchase price costs 2 times more the Powerhorse.
great video would love to see the same test with the Honda 3000 and the predator 3500
Great idea 💡
wow, 30% longer, even the carburetor was often modified to run very lean, mine need a full choke to start even on summer (86F 30C)
Great video,hey Gavin can you tell me what do you think about the emissions between the carburetor and fuel injected generators are they about the same?
I can’t measure the emissions but the carburetor will probably have more because the fuel injection regulates the fuel usage to be more efficient
@@GeneratorReviews ok thank you
Thanx fore the test 100%
Any time!
Yes, do a video on vacum gas tank and getting a generator for storage, thank you
Can you test the 4500 power smart ?? It’s a very compact inverter with a 224cc engine. What impresses me is it’s small size with a 1.9 gallon tank runs 14 hours.
Power smart just contacted me I will ask about the 4500
@@GeneratorReviews it’s a closed frame model not the open frame. I’m just impressed how small and compact at 70 pound for a 224cc
Hi Gavin, watched a lot of your videos on generators. Just went through Ian here in SWFL and have used a Honda 2000i for power to essential devices...I love that it will run 12 hrs on one gal of gas powering refrig, freezer and computer.....but would like to be able to backfeed house panel to run water heater, stove or other for short periods of time......I love the honda's but $5000 is way over priced.....so I'm thinking 2 Genmax 3500 units tied together to feed a 50 amp plug coming off of the panel. could you do a video on how to wire what I am talking about and discuss the fuel efficiency of 2 smaller units vs one big unit?
Yes I will do that, great idea 💡
Does the parallel GenMax setup produce 240v? I took a quick look and only saw references to 120v - you’ll need 240 for the stove.
@@davincrook9927 yes it puts out 240v
GAVIN, DOES THE HONDA EU7000 HAVE THE TWO WIRE START/STOP CONNECTION LIKE THE EU70?
No it doesn’t have that
EXCELLENT VIDEO AND TOPIC GALVIN BUT DO THE GENERATORS HAVE THE SAME ENGINE SIZE?
The Honda EU7000iS houses a 389 cc Honda GX390 EFI OHV 4-stroke engine and The Powerhorse 7500i's engine, 420 cc OHV 4-stroke.
The smaller engine and fuel injection really helps. The Honda claimed the fuel efficiency.
@@GeneratorReviews DO YOU THINK THE DIFFERENCE IN ENGINE SIZE ALSO BECOMES A FACTOR IN THE TEST,
Regarding the kill-a-watt not fitting. I have a short VERY heavy gauge cable I use sometimes. Its on ly maybe a foot long. But it has 1 male plug on one side to lug into the outlet and on the other end it has a splitter to have 3 outlets. You could plug something like that into the Honda and the kill-a-watt into that with the lights plugged into it. I know it's an old video. But that little short extension cord shouldn't affect the results for anything you test in the future. Good video.
I'm about to buy one of the Hondas by the way.
Powerhorse is about1/2 the price of the Honda. I use my generator for back up power snd it might average 24 hours per year, so for me the Powerhorse wins hands down.
Excellent review. I wonder what your neighborhood thinks of all the noise? Let's crudely compare the options... Honda 7000, $5K, Powerhorse 7500i $2.5K. Efficiency and longevity probably goes to the Honda. Powerhorse wins on the 50amp plug, Db, and price. For intermittent use to power a house, I would probably go with two Powerhouses and a combiner box.
100% agreed but the power horse does not need a combiner box because it has a 50 amp plug
And my neighbors don’t mind because push come to shove who else they gonna go to for help 😅 in a power outage situation, they’ll have a generator.
@@GeneratorReviews Noise is no issue for most inverters. With a light to medium load, if I walk 20 ft. away from my EU3000is, I have to strain to hear it. Believe it or not, the larger Honda 7000 or Powerhorse 7500i, is even quieter than the smaller EU3000is because they stay at almost idle with light loads.
@@seymourscagnetti1413 yep they are crazy quiet
@@GeneratorReviews Would I not need two to supply a split phase 240v system?
@@stldigitalmemories nope it puts out 240v
And, if the on-machine power meters were accurate it the Honda gave almost 5% more watt hours to boot. Does the Powerhorse run at a lower voltage?
A T Burke
It runs at 124 volts
@@GeneratorReviews Thank you, Sir. I thought a difference in voltage might have caused the difference in output reading. So, are we down to either having a faulty onboard meter or a slight difference in the resistance of one or more of the lights?
A T Burke
Honda are the best. Best Stator Technology, Best Rotor Tech that will sustain electrical wearing for decades. What about the prestine outstanding reliable engine that no one can compete with it. You have the choice made and design in China/‘USA’ vs Japan pure thinking about everything.
I got the chance to try both and the Honda outperformed the Powerhorse. First thing, The Powerhorse had problem starting, second the fuel tank in the Powerhorse is bigger, that tells me that in order to run the same time as the Honda it needs more fuel. My Honda runs for up to 18 hours on 5 gallons. Also my Honda, ran almost non stop from Sep thru Dec 2017 after Hurricane Maria.
I agree with you Jose the Honda is bulletproof but most people can’t touch the price even though you make up for the price in time.
@@GeneratorReviews The Honda price is insane.
I just received my Honda Eu7000 Tuesday of this week in Ft Myers FL. What excellent timing! Cat 3 coming in 4 days. I am most thoroughly impressed with it. Super quiet and super quality. Just finished wiring Reliance Transfer switch today. Looking forward to seeing what this Gen can do. Main Fear? Someone trying to steal it!
@@stbentoak5047 Stay safe 👍🏾👊🏾💯
@@stbentoak5047 Hope you’re OK after the hurricane, it was absolutely a bad one. I live in Miami and are thankful we were spared this time. I’ve owned the earlier EM7000is since the 2004-2005 hurricane season and it has been a great generator. I chain mine to the house using a 1/2 inch hardened chain and Master 🔒.
Which unit is more easily accessible to service?
Both are easily accessible to service northern tools are all over the place and will service the powerhorse
A good comparison would be if the engines are identical in size… one could be smaller than the other using less fuel even if they are injected or carborated
Practically speaking, they are in the sense they’re both rated for ~7000 watts. The displacement isn’t a metric that matters IMO - it’s the fuel efficiency, power, weight, etc. that do
@@davincrook9927 ofcourse displacement matters lol
With carburetors its all about jetting for your elevation and temperature. Both engines will only run so lean . The efi gen is obviously self adjusting leaner then the carburetor generator is jetted.
which one will run after an EMP? if either.
I will put a turbine on a bicycle and pedal it to power everything if that happens 😅
So how is fuel pressurized in the Honda? In-tank fuel pump? My point is that most generators "just sit"...some for years between actual uses. If that fuel pump goes bad, especially due to lack of use, and then you need that generator you might be wishing for the simplicity of a carb. Something to consider. Nice review.
Great point!! But I think everyone should run their Generators at least once every few months to prevent this from happening
Thanks for the comment 👊🏾👍🏾😎💯
Can the Honda run your 5 ton? That is the video I want to see. Make sure to capture the inrush peak.
I will👍🏾💯
Honda for the win🎉
But I’ll take the Powerhorse for the 50amp plug and price
Question is, will the Powerhorse last as long as the Honda? I have a Honda that ran almost nonstop from Sep thru Dec 2017 after Hurricane Maria. Last week this past weekend I used for hurricane Fiona, it performed flawlessly. The fuel injection is far superior.
generators have twist-lock plugs for a reason. They vibrate a lot! Given enough run time, non-twist-lock plugs will back out and could cause a fire hazard!
Another factor, as others have stated, is that the Honda has a 389cc engine and the PowerHorse has a 420cc engine. Bigger engine consumes more fuel. The carb didn't help either.
Yep yep 👍👍
you can use your kilowatt meter on honda. Just get a 1 or 2 foot extension cord. Than plug meter into that. They do make short extension cords. Construction grade
Yes, I knew I could do that but when testing I have to make sure everything is equal because everyone finds the smallest mistake I made, and go crazy with it. In the comments😅
@@GeneratorReviews well, if they want to, than they could say you had the watt meter plugged into the powerhorse but not the Honda, thus the powerhorse took more fuel sooner. But, yea, I get what you are talking about.
honda piece of mind
Was the Honda in Eco mode?
They both were in Eco mode
The longest my Honda has run on a tank of gas was 19 hours. That was hooked up to the house during the summer. Your mileage may vary.
Honda is the best at everything cost is higher for the Honda but you get what you pay for
Totally Agree 👍
Honda FTW :) Power Horse ~40 Mins Honda 52 Mins 39 Secs
Side note: the Honda has a fuel pump letting it run out of fuel will damage it eventually. eg. a fuel injected vehicle fuel pump.
Sacrificing my pump for the test that’s one test I won’t be doing again😅
What about at a 7000watt load?
I can try that.
honda #1
At Wattage perspectives , Honda outperform much better;
At engine size perspective, this is just how physics worked
Well said sir👍🏾💯
The Honda will stop once the fuel pump stops supplying pressure while the Powerhorse will stop once the carb bowl has drained too far. This should be fun:)
My neighbor recently bought the EU7000is fuel injected model with the shop service manual. Just going over it and it is pretty much a single cylinder engine brought up to the 21-1/3 century.
Like a modern car, it has a barometric sensor, oxygen sensor, crankcase position sensor, throttle position sensor, exhaust manifold temperature sensor, and generator control unit (GCU). I am not surprised that it can milk every ounce of energy out of the fuel it is given. The only thing missing is an OBD2 interface so you can hookup a scan tool to see the real time performance of the engine like fuel trim, rpm, timing advance, etc.
It has its own propriatary diagnostics port. DLC "Data Link Connector" they call it. You can get all that information out of the GCU with the right tools.
Just like my 50cc Honda scooter.
Your wife going to be pissed off you putting gasoline in her favorite measuring cup!
I think it was worth it though.
🤫😆that was apple juice 😅
Wow... That is pretty impressive for both of them. Another comparison loading each up to 50% and 75% load on each would tell if there are differences in how the inverters handle power loading. I have an older no-name Chinese 5500 watt (6000 surge), *non inverter* generator. I just ran a test a few weeks ago. I used 32 ounces (1 qt) of fuel. I used two 1500 w heat guns on high. So 3000 of 5500 watts is a 55% load. It ran just for 23 minutes and a few seconds.
Anyway, double the price for the Honda, I'd have to stay with the other options. If you have Nat Gas, (conversion kit) you don;'t have to run all over the place finding large quanties of gasoline for extended outage. But - that isn't likely an option for the Honda Fuel injection...
This is why cars moved to Fuel Injection from Carburetors years ago. I knew what the outcome would be before the test was run. The only question I had was for how much longer. You look at this result, and now think of larger Engines, running gallons of gas, and it makes a huge difference.
Well said sir👍🏾👌🏾💯
I like the smaller generators because I know you would have gotten more fuel economy or efficiency out of the smaller generators than these bigger generators.
I’m actually going to do that exact test with the same amount of fuel in each one.
large generator versus a smaller one fuel efficiency test
@@GeneratorReviews I'll be sure to look out for it. I know that Honda sure does look like a nice generator though I know it's pretty darn expensive but it sure looks like a nice generator especially for more power.
When the works gets gummed up you can tear a carburetor down, and clean it up to start. If you have the better one - fuel injection - then you are probably out of power until the storm is over. then all you have to do is figure out how to get the 200 lb monster to the repair shop.
😅Agreed ☝🏽
Hmm.. The Honda really is under rated.
If you didn’t use the fuel tanks it would of been a fair test. You introduced too many variables if you were to use a separate tank and measure out the same with no variation in tank and bottom design your results would be more accurate.
You’re right, but I always try to do a real world test as it sits we’re not testing the engine we’re testing the tanks and fuel lines.
we’re testing the complete system seeing how efficient the generator tank is at getting every ounce of fuel into that engine.
But I do understand your point
Well, one of these engines uses a fuel pump in the gas tank to provide pressure for the injection system while the other uses gravity. the Powerhorse will use all it's fuel minus small amount left in carb bowl while the Honda will stop running when the fuel pump stops providing pressure to the injector. The best way to do this test is to run both generators for the same amount of time and measure what was used:) I would expect the Honda to use less fuel because the generator can better optimize itself for altitude.
He should have sucked out most of the fuel, but left enough that they could both run with a load, let them run out of fuel, and then added an equal amount to both of them.
@@erik_dk842 that’s exactly what I did. I made them completely run out before I started the test. They both ran out and I tried to start them.
@@GeneratorReviews Thanks for your reply. I was under the impression that you just sucked out the fuel
Gasoline is too hard to get in an emergency I need mine to be converted to propane Does anybody know if the Honda can be converted????
The last big freeze we had every gas station around me ran out of gas. I drove 40 miles to a gas station only to get 5 gallons per customer.
😩
Pretty much all of them can be converted you just have to find the right kit.
ruclips.net/video/g-X1b5BX4II/видео.html
Yes the Honda ran longer but it is also twice the cost of the Powerhouse. Which i think that is something that should be considered....
Well said sir! I agree with you and the powerhorse is also quieter.
Remember you pay what you get !!!
Wow, that's about 40% more running time from Honda.
Whom ever make the wheels , makes for both !
The wheels, the handle, and all the switches identical
Put put six or seven KW on them and see which one runs longer
Great idea 💡
So that's 2 kWh per gal for Powerhorse and 2.8 kWh/gal for Honda. That is way short of typical small generator efficiency of 4 kWh/gal. You need to try these at 50% rated load or 3500 watts instead of 15% load.
That's because they ran at such a low load. A generator will run most efficient when running close to 100%.
Honda # 1 again you get what you pay for-Japanese vs chinese no compare long term either
Hey G'
Powerhorse
You could have used the kilowatt meter with an extension cord - FYI
Then someone else will comment, you didn’t keep the test the same. Thrust me I get all the keyboard warriors in the comments.
@@GeneratorReviews hey I want you to know it was a really good video first off. But ok about the cord idea : ) it was just a thought - I believe that for sure - but I guess you could use two of the same extension cords or I’ve even seen some little one foot cords that have a threeway on the end
I suspect the Honda just has a better engine overall and being fuel injected makes no difference than a carb.
Hope you didn’t put that measuring cup back in the kitchen
😅😁🤫 I didn’t
😛
Carbs are 25 dollars on Amazon
Hondas are one of the overall best thats made. You got to pay for quality
Honda - Smaller and FI.
Robert 👊🏾👍🏾💯👌🏾
Powerhorse
Probably alot less co emmisions
So.... the Honda would burn around .32 gal/hr for 16 hours. That surely would be based on 25% load or less. I'd guess at 50% load, it would be more like .5 gal/hr or more. At 75% load -guessing .7-.8 gal/hr. If you ran 50% load for 8 of 24 hours, thats up around 4 gal/hr. If you had no line power for 5 days. would be 40 gallons of gas if math is correct. That's eight gas cans of 5 gal each. Someone ✔✔ the math. 40 gallons x $5/gal=$200 $40 day? After a major event like Florida's most recent hurricane, where would you find gasoline, much less 40 gallons and have to store it.
MADE IN CHINA will never compare with HONDA JAPAN ! Honda win every time !
Test is not 100% reliable because not every tank empties the same. So one generator could run out of fuel sooner than the other because of tank design and not because of fuel consumption.
And you’ll get a better fuel efficiency with a full tank, but like I said, in the video, this is not rocket science, entertainment purposes, only just have fun with it life is short.😊👊🏾
Honda is the gold standard, just way too expensive if you only plan light usage, maybe if you plan to run it for a business or something it would be worth it
Agreed 👍🏾
We suffer constant power outages and the Honda has proven itself many times.
Honda
My guess is Honda
Yep 👍🏾
Other fuel inyector generator more shipper
Big mistake! Empty gas tank is a great BOMB full of gas/air mixture! Let's store them like we do a prop airplane. Every plane is ALWAYS stored with FULL tanks for great reason, to prevent your empty tank from breathing. Night comes. Empty tank air shrinks and sucks in moist air thru vent. The cold tank all night causes the dew air to condense on the tank into droplets which slide down the walls rusting the inside of the tank and collecting at the outlet to your engine. Day comes, temp rises pushing air out the vent. Night comes and the dew air gets sucked in to repeat the process. Water gets sucked into the plane engine causing a CRASH!! Full tanks can't breathe. Gas in a full tank doesn't breathe out the light aromatics so the gas NEVER GOES BAD! No magic potions are required like STABIL to keep the gas fresh. Full tanks contain NO EXPLOSIVE MIXTURES! No air in the tank...no burning! ALWAYS store planes/cars/gas-powered anything FULL TO THE LINE.
Just use an cord between the genset and powemeter😂😂😂
😅 ok
Much more expensive repairs on EFI
True….👍🏾💯
Significantly different situation, but I owned an EFI Polaris Sportsman and an carb Polaris Sportsman. The only difference was EFI. 2003 vs 2003.5 model year. Bought them a few months apart. The EFI had way more power, way more throttle resolution, and way, way more range. Carburetors are the stupidest caveman tech. Welcome to 1930!
The carburetors are pretty much calibrated for middle of the road performance the the EFI recalibrates as the load changes gives you a streamline operation
(welcome to 1930)😅
bUt yOu cAn fIx a carb with a sCrEwdrIver. Standard Neanderthal defense of carbs.
@@erik_dk842 Love this response!
Properly adjusted carbureted engines normally run rich (over fuel) at higher altitudes and run lean (under fuel) at lower altitudes.
