- After watching all the “great” reviews about the Predator 9500 watt inverter generator, we decided to purchase one to run our entire shop.
What a mistake that was!
In this video, we put it to the test! The real test!
Will the Predator 9500 run an industrial size air compressor?
Will the predator 9500 run a small welder?
Is this predator 9500 any better than one half it’s size?
Watch this video to get all your real answers before buying a predator 9500.
So if you want this generator to power equipment that’s pulls more than the generator can supply, don’t buy it. 😂 Brutal review.
I bought a chevy bolt. Don't buy it. It can't do 300 miles an hour.
I have a 2 year old predator 9000 generator and recently lost power. I had already installed my transfer switch so I hooked up generator and got it started in the 7 degree temps. It did a wonderful job. I had lights, furnace heat, tv, internet, 2 refrigerators and a freezer running at the same time. Great generator for the price!
The 9500 is an invertor generator and the 9000 is a standard one. It's a little different how they make and put out power. The standards tend to take abuse a fair bit better
@@G.A.N.G101 standard gens are not good for Electronic devices, because of the dirty electric they put out. {TV's, Computers, etc.}
@@Boobtube.Good to know that thanks for the info
@@Boobtube.the predator 13000 has a AVR that puts out electricity that is safe for electric appliances. TVs . Bought one no problem.
@@user-th8sz1wu3o uh, ok... but this video is about the 9xxx series.
Was a compressor service guy for many years. You would be surprised at how many people buy these and can't get them to start even wired to their house. Takes 2-3x amps at start up. Not shocked at all you couldnt get it started. The starting power needed exceeds the generator. That said, have the smaller predator and love it so far. I think the benefit of this one is the 220v output.
More like 5x than running amps. & If the tank is at high pressure it would take even more current. Close to locked rotor amps. One way around this is to use a vfd which comes with built-in soft start & will slowly raise the current. Or even better if want to power appliances Iike air compressor. Get a real diesel generator, even an old one should be more reliable than any portable generators out there fit it with avr & generator control panel & u have a perfect generator to start any load & it will be lot cheaper to run.
Exactly correct. Air compressors are notorious power hogs at startup. The motor nameplate can be misleading for startup amps. As KuntalGhosh states 3x to 5x may be more like it for some without a cycling pressure switch with an air relief valve to eliminate the startup pressure.
Some of those compressors have 3 phase motors
Highly recommend this 9500. . These guys are full of it, I’ve had one for 2 years and forced to use multiple times, worked perfect for the money we spent.
Sir, are you able to power your furnace from it? I’m thinking of purchasing one
I started my welding business with this generator. Bought it 3 years ago and ran it hard and wide open since day 1. I have never had a problem other than the electric start. I run all my 220 welders, stick, flux core, tig and a 50amp plasma cutter. It will pop the breaker on the generator if I run the plasma anything past 40 amps. Other than that it has ran anything I throw at it. Now with 1800 hours on it I still use it for our camper since I bought a new engine drive welder. I would recommend this gen to anyone
What engine drive welder did you go with?
I have a Westinghouse generator this size mounted on a trailer that I grounded the frame to. I welded on some new light brackets to the trailer and ever since the electric start quit working. I wasn't running the gen at the time, welder was plugged into the shop electric and obviously grounded to the shop as well. Is that what happened to yours?
Just because of this very intelligent review, I’m going to Harbour Freight and buy this model
I wouldn’t recommend it
Getting pissed that a $2k generator wouldn’t run an off grid shop is ridiculous. This generator isn’t built for that. You guys need a 7.5kw pull behind unit to do what your asking. Look at industries(oil rigs in remote Wyoming) that have similar requirements to you and go from there.
It is designed to run a home with appliances that don’t pull massive amounts of power at start up, ie furnaces, refrigerator, stove, lights, water heater, electronics. And it is an inverter generator to prevent destroying delicate electrical devices.
I have this exact generator that I paid about $1600 for. It ran my house and garage for 3 days this year already with zero issues. I couldn’t go any cheaper than this on a unit because a 3500 can’t take the load for a whole home. It fills a niche market, and that market isn’t industrial compressors and off grid repair shops.
You hit the nail on the head and I think people need to see this more. I like to collect what I'll call "sharp things" - and there is a quite famous German dude who beats the shit out of knives/axes/etc. until they're DEAD AF and then say "See it's a piece of shit!" ... No dude, normal people don't stab the roof of their car 1000s of times trying to break a fuckin knife. Just because this generator didn't do what they knew damn well it wouldn't be able to do doesn't mean it's not a great piece of kit etc. and probably exactly what it's designed for , imagine that!
Electric motors like your air compressor require a HUGE surge in additional current to get them going. Industrial installations of such motors often include a device consisting of capacitors, inductors and voltage phase/amplitude matching. Savvy garage owners add such devices to their electrical panel to cover surges that would otherwise cause a generator to cough.
Alternatively, use the generator as an alternative means of charging your home battery when the grid is down or the sun won't shine and the wind has died.
That's the reason u have a gas powered generator in my van. Despite having a generator too
As others have said, that compressor is going to stall any but the biggest generators out there, even with a soft-start. Inverter generators are built for 2 things, true sinewave clean power and being quiet. Clean power for a shop is an oxymoron, all your equipment could run on 20% THD and never miss a beat. It will however fry your computers, laptop and TV etc. in a heartbeat. That genset is perfect for running a modern home as a backup, well, I would want it to run propane or natural gas rather than gasoline, but kits are available. What you boys want is one of those Mil surplus diesel gen sets on a skid to run that shop.
That old wives tale about pure sine for computers is no longer valid unless your equipment has a big transformer power supply. Modern electronics uses a switcher power supply that immediately rectifies whatever it's fed and feeds hvdc to the switcher. Your switcher will run fine on any voltage and frequency from 90-260VAC without you flipping switches. Noisy, cheap inverters are judt fine...
Except for the welder, stick welding you need clean power because even at 80 amps on 240v theirs a huge difference, you think you can weld OK with a 240v non inverter generator with welder plugged into it at home but your welds look like crap with a non inverter power to welder vs a 240v clean power output to welder.
@@LarryButler-kp3se Larry, don't bother. Parrots are gonna parrot. They believe the old wives' tales. Nothing will make them see the light. 73!
Dude, you knew that would not start that compressor. That thing is huge!
Part of what you pay for on that particular generator is also the sound insulation. And as mentioned below, and as anyone with electric motor experience know, start-up power demand is significantly higher than run demand.
I live off grid, and during construction went through 3 generators: First a Firman (started using lots of oil and finally died), a Generec (just died) and lastly the smaller (and smaller than the other 2) 3500W Predator. I have over 1200 hrs on the Predator and it is fantastic! I have since bought the 9500W Predator (only have 25 hrs on it so far) and am really happy with it - BUT don't think it can produce more than maybe 8000-8500W continuously.
What’s your hours looking like now on the 9500
Get a soft starter for your compressor
"Locked Rotor" or starting amps is usually six times the run amps. Voltage drop is critical for all motors so wire/cord size is just as crucial. To Me it looked like your Generator power cord was too long and too small of wire gauge(#6 or #4 wire a must). The longer the run the larger the wire size to get the oomph to get motors started. Volts x Amps = Watts, I hate talking in Wattage for motors and associated load but it's easy enough to convert with the formula I gave. I heard you say 5500 watts for the air compressor, so it would take 33,000 watts at 220 Volts to start it clean. Yes, that's 150 Amps inrush to fire that motor without burning it up! So you need a 33.5KW Generator to start that monster air compressor alone! Three Phase is more efficient but you will only find it in a Commercial Building area. You guys get to Work! Enjoyed your content.............M-
Length of wire is important. Why in the world you would want the cord from the generator to the shop building as long as that I couldn't guess.
@@peterkizer6163 - simple answer, carbon monoxide (keeping it away from the building).
It takes a lot of amps to start a 240 volt compressor. The 9500 predator is only 6700 watts running and obviously doesn't do the 9500 even at start up.
I have a 3500 predator invertor and i love it. Got around 300 hours on it. I got cheap though off the clearance table after somebody else returned it. I'd have never bought it for full price but for $350 i almost had to.
We thought it would take 1.5 times the amount of amps to start it. It's definitely a tough pill to swallow at 2 grand. That's why we don't think it's worth it among other reasons
@@G.A.N.G101 oh yes definitely not worth the money.
I had a 9500 running 12000 starting generator that would just barely start my 240v 60gal compressor.
I wound up just converting the comp to a gas engine. It's fairly easy to do and a lot cheaper than a big generator.
@@G.A.N.G101 can be up to 10 X starting for less than 500 ms. Need to work out the surge current capacity of the generator and compressor.
@@G.A.N.G101 Compressor probably takes 30 amps just running, LRA is alot more. Next time do some homework on the specs of the generator and air compressor before putting up a video that makes you look stupid..
Starting current and running current are two entirely different beasts. I'd love to see the inrush current peak on that compressor. I'd bet my 401k it's over 9500 watts.
yeah but an activestart would solve that problem.
Might want to check the lock rotor amps of that compressor motor. It should be on the name plate LRA . I bet it’s over 80 amps. You would need to add a soft start kit for a generator to start it.
You are correct, the manual specifies an 80 A breaker. Gotta RTFM.
@@stevengpreston breakers generally won’t react fast enough to trip off LRA . The breaker size is based on MCA or minimum circuit ampacity that’s what the unit run on. The MOCP maximum over current protection would be the actual maximum breaker size
I would have checked the actual amp draw of compressor by using an amp meter to see what it is pulling.
Its the start amps on the inductive loads like this that draw the most. It may be 30amps running, but something that size may be asking for upwards of 70amps to start it. WELL beyond the speck sheet of the gen set. I can't say this is a far review of the product. This generator will not start a 5 ton AC unit drawing 25 amps running. In rush on something like that is about 60 amps. An easy start makes it possible to start up amd run a 5 ton unit.
Again. My 2 cents, not a far shake on the generator.
Yes. A cheaper generator can do what this one does but at the cost of more fuel and dirty power.
I don’t know guys. My 9500 ran the whole house minus the Ac and stove for 5 days during the last tornado we had. That includes 3 refrigerators, lights and microwave, water pump and water heater. About 2400 sqft
It’s possible we got a dud
Approximately 6 1/2 years ago I bought the harbor freight 8750. It is not the inverter generator. I bought it as a back up power source for my mobile welding so I didn’t have to run my engine drive all the time to power lights grinders etc. I have run a 220 V wire feed welder, TIG welder, and stick welder off said generator with zero issues. I’ve used it multiple times when the power is out to run my whole house. If you make a jumper kind of like the one you have “yellow” and only pour one leg of power wired into a single 120 V plug kind of like the one you cut off you can run that welder and that small compressor at the same time with no issues because you’ll be running off a 30 amp breaker instead of a 15-20 amp breaker
I have heard bad things about the Predator generators from other UA-camrs but mainly about the durability of them. I have another Chinese made brand that an electrician recommended, Firman, sold at Costco. Have only used it a couple times to power the house during outages and seems to be ok. It’s a Tri-gas which can run on either gasoline, propane, or natural gas which is nice. maximum power only comes from gasoline but propane works sufficiently for what we need. Bought a 40 gallon RV tank so that we can run generator for days without refueling. Hope you can return yours and find what you need. Thanks for the info, God Bless 👍
Yeah that Firman is nice. If that don't work then forget it.
I’ve had 3 firman generators. 2 of the biggest and 1 of the smallest. They were the biggest pieces of junk in the world. One burned tons of oil to the point where I couldn’t keep up topping it off without it being an absolute inconvenienced, the other’s power output was totally fried. The small one just quit putting out power. I got the 9500 and loved it so much I got a 2nd. Weird how some people have totally different experiences.
Precisely why these are not “job site” generators. I have powered two 33+ foot travel trailers at the same time with my 9500.
Not sure what your guys problem was. I just ran my whole house for 9 days straight 24hours a day. Including my 5hp ag well pump. Whole house furnace etc. Lights TV. Basically ran the house like I still had normal power going into it. No issues at all.
I doubt your house also had a 10 hourse power, 2 stage industrial air compressor!
Are you selling it? I’ll buy it.
I have a 10k generator which does my entire house....As far as starting a 7.5 hp compressor I don't think so. I have an industrial 5hp unit and it draws a lot from the pole. The starting current is amazing. Way over the running current. I think my generator has a 50 amp output I wouldn't think it would fire up my compressor. wires 8ga or 6ga...Should have a 60 amp breaker for yours..20k generator
You're asking WAY too much of that generator. Most of the comments stating the high start up draw are quite correct, especially starting a motor rated at 7.5hp.
2 to 3 times starting draw isn't an exaggeration, it can be more, depending on motor. 11600 to 17400 watt surge or more is a lot when stacked up against a 9500 surge watt genny. Try buying another one and run them in parallel. It might work, but you never know. After all, it's only money. Good luck.
I love your approach
Truth is entertaining..every homesteader has had issues with that brand of generator...🥴
Would you guys quit stealing all the stop signs We had a fender bender up the road from you because neither of us stopped
😅😂😝
😂 this garage was full of signs when we purchased this place! I’ve always wondered how many people crashed because of it! 😆
Something's not right here. This generator will generally power lots of equipment simultaneously. I have one and it works great. My is new and I haven't had a chance to use it extensively, but I've powered a few things without problems including larger home compressor. Not an industrial one like yours. Maybe that thing requires a much greater amp draw than you thought? There are lots of reviews of people putting bigger loads on theirs with no problems, running every single thing including microwaves and air conditioners in huge RVs etc without a so much as a whimper. Or maybe you just ended up with one that isn't running correctly? I noticed you still have it in a recent video. If you weren't satisfied with it why didn't you take it back? It's got a satisfaction money back guarantee. Again, this generator has tons of rave reviews so not sure why your experience wasn't good, but seems something is amiss.
We are a couple hour drive to return the generator. We have 90 days to return it. So we are milking it until we get our grid power service hooked up. But yes we will be taking it back
All your tests are with devices that have huge reactive load requirements. The inverter generator isn't going to be able to sustain this, because it's electronically creating the sine wave and it's going to trip out every time. If you used a conventional alternator head instead, you wouldn't be experiencing the trip outs due to the mechanical inertia remaining in the generator. Also, you might mention suicide cords aren't really the best way to power the building with.
I have run a couple of refrigerators and our house's heat pump (soft start installed on it) in air conditionig mode with the 9500. It would never have run the heat pump without the soft start because in has an lock rotor current of roughly 90A, and the soft start gets it down to 18A. I will be getting a second one to run in parallel--we have an all-electric home.
I have a 5500 Coleman running for 3 days on my place 100' extension cord just my freezer my refrigerator 2 battery chargers and 2 shop fans and my little air compressor (occasionally)
Then on all the way to the back property 300' away my in-laws their refrigerator a freezer and a fan. And chargers. Wires didn't even heat up worked great. I was thinking of upgrading to one of these but I think I'll keep mine. Upgrading to something better.
i have this gen. manual transfer switch- switching 200 amp service. 6/3 with ground coming from generator location. location is about 55 ft or so from my panel/transfer switch. the reason for this is to get it away from sleeping area. even though its quite enough . i also needed to be near my fuel source.. Nat Gas. i installed a conversion kit on it. on natural gas which lessens the wattage rating. i have had every light on in my 2500sw ft home. fridge calling to cool. furnace running on high heat. tv on. audio hardware on. not a single issue. drawing about 20 amps at various times from each leg. i ran a 220v 4000 watt electric heater in my garage. and lights. and tools while installing the transfer switch wile meter pulled. not one issue.
the issue as it has been said previous is the inrush - this is a larger what looks to be magnetic start compressor. startup wattage/amprage is going to be at least double possibly a bit more. the rated running wattage. you would need to have a bigger generator either larger inverter model or larger regular model. or parallel two of these together. also. i am hoping this shop was just a stand alone building with no actual utility service to it. with how it was wired in. even so . there should never be a cord like that used - in any application.
You need 2 of those linked up to each other because there inverter generators buy another and make a suicide cord and plug them into each other and start them both then slip the shop breaker on and you will have 18k watts and it will power everything. Run just one generator when you don't need allot of power. Also be sure to unplug the suicide cord if you will not be running both generators. Or they may even make a kit to link the 2 up with each other. Of not a suicide cord 110 to 110 of each generator will suffice
Thank you for the video. It helps a lot to have this information.
Let me say “that is not the correct application for that compressor!!” I am so observant! I am an electrician and would never recommend that generator for that application. You need a 22kw generator minimum for what you are doing
Motors require 150% of the full load amps at start up, same goes for welders.
Volts x amps = watts. Check your amps/volts to see if you’re overloaded. Just a thought. Nice video 👍🏻
The inrush current on that large motor/compressor is well over the 30amps and like others people have commented there are ways to make that compressor run from that generator. Hire a good electrician and he will know how to put a soft start or install capacitors to help with inrush current.
The fix is a bigger diesel generator, or a smaller compressor. Or a non-off grid shop with 100 amps minimum of 240 V power. Always run the lightest fully synthetic compressor oil you can get, while having it warm inside and a low-tank pressure start-up. Then swim at your own risk.
They stated they will be sand blasting -- that takes a high CFM output air compressor.
@@OHUQTU So, bigger diesel generator it is.
Waaaaay to much to ask for that generator to start 7-1/2 hp compressor. The start current is at least twice the running current and way more than the surge rating of that generator. Wrong tool for the job, not a bad tool. You would need a tow behind generator or approaching an industrial size. By the way, glad you adhered to the break-in instructions🥴
I think the Predator 9000 W would have been a better deal for you since it has plenty of power
and does cost a bunch less too.
I think you guys got one with a bad inverter but also that is way too much compressor unless you have two parallel together I have three predators an older non-inverter that I’ve had since 2014 still runs great and two inverters 3500 I basically use the two 3500s paralleled to run my house at night time when the power is out since it only does 120 but I get 50 A with two units and I use the other one in the daytime when I need 240 my older one has 1000 hours on it the other two have 200 hours have had zero problems I added meters on my breaker box for my interlock so I can see how many amps I am pulling on each leg so that I don’t overload it is very helpful.
I have their older style, largest generator, and i tested it having a 220 hot shot heater and another space heater at the same time while plugging in other items and it did well. I wonder if its just that model or that one is just a clunker and try another one. By the way great seeing you guys, its been a spell since the last time you uploaded.
We talked to harbor freight and they said we should bring it back and swap it out and see if that helps.
@@G.A.N.G101 Hopefully it works out better for you.
Starting current is 3X higher then a running current
Good shipping, easy set up and start
Before you buy generation, you must calculation how many jump power you need in?
Starting current on a 9000 watt motor UNDER LOAD is around 18KW. The surge current on the welder is similar. Buy a 30KVA or larger diesel generator USED like my 33KW, 4 cyl commercial with auto switchgeear.
Sad you guys didn't have a good experience with that Predator 9500 - Mines works great and it powers my home with a 5 tone AC unit w/Soft start, 2 refrigerators, 2 ceiling fans, sump pump and kitchen lights. Maybe you guys got a lemon.
Try the non inverter version? Its mostly smaller electronics that really need the inverter from what I've seen. Maybe you'll have better luck that way? Would love to see the comparison!
This guys are crazy, they just don’t want pay electric bills, predator is just for emergency or small jobs, for trailers or camper
Yeah ok
THD from NON inverter generators - Northern tool brand Powerhorse and NorthStar ALL have less than 5% THD. They give you the wattage needed, and
Jeeez boys, you should have read a basic electrical/generator book before the purchase and you would have found that startup current on an a/c motor runs 3 to 6 times the operating wattage. So 7 1/2 hp = 16,875 to 33,750 watts to start, your little generator did not have a chance!!
When you are dealing with any generator to run an electric motor you need to look at that motors locked rotor current (LRC)not the running amps. If the LRC is more than your generator starting current then well it’s not going to work. The electric motor will never overcome the low voltage to get to full running speed and either trip the overload or breaker.
That compressor has a surge of like 10k+ when warm. Almost 15k cold.
Need 2 times the full load amps on the compressor name plate to be able to start it properly
Great video. I never thought of testing my generator like that. I am going to see if my gen can run my welder, lights and air compressor.
Thanks! It's definitely worth knowing what they'll do.
The Ingersoll Rand 7.5 hp compressor pulls 9200 watts. WAY more than this generator is rated for continuously. Wrong tool for the job.
Would this generator be able to run a 3.7 hp 15.7 amp 30 gallon air compressor?
My compressor requires a fuse- delay type breaker for start up … perhaps that may be the issue??
I bought the genmax 6000xie open frame inverter and my 14 amp ryobi circular saw will make the overload light come on when NOT in economy mode, so at full power 1700 watts is almost too much for a 6000 surge rated generator. I think it's that the inverters just don't like induction motors my well pump I have wired to 240v is I believe 7.5 amps dogs the thing down aswell. Mind you it does catch up with these loads and the voltage comes back up to normal operating range but it's just really disappointing when you spend the money on these things and they can hardly handle anything you'd expect them to. Don't even ask about my 20amp 240 volt compressor no way I'd need a new start up capacitor every day the way it starts that up lol.
I definitely agree about the inverter generators not being able to take the same amount of abuse as a regular style. I have a 5500 champion that's super loud but seems to put up with surges significantly better. I only spent 300 bucks on that used.
Thanks for warning us about this piece of durian.
I bought a magnetic dip stick to help clean the oil during the break in period of my Predator genny. I was very surprised at the amount of metal shavings it picked up. I definitely recommend buying one from Jeff Bezos
I've had one since they came out I'm a carpenter I use it everyday runs 7 hrs a day maintenance is preformed at scheduled times synthetic oil and I've never had an issue.I run a tablesaw chopsaw fan radio gluegun and a pancake compressor
I can't understand how you ever thought that generator would start that compressor. You need to do some math before you go spending money on the wrong thing. Start with the locked rotor amps (LRA). Some items have this labeled "instantaneous start amperage". Air compressors are notorious power hogs at startup. The motor nameplate can be misleading for startup amps. As KuntalGhosh states 3x to 5x FLA may be more like it for some without a cycling pressure control with an air relief valve to eliminate the startup pressure.
Wrong generator for the job, that type is for clean power...not surge power lime hou need.
Also work on your sound...either can't hear you or you scare the dead with how LOUD the sound is!
Good video , thanks for sharing , God bless !
How can you expect to run a whole shop……I do not agree with these guys….i bought one 2 years ago and it’s an AWESOME GENERATOR ….
Hey, can you try this? Switch off the Eco mode if it has one. That should put it at full power from the start. Motor start will still be a problem but I wonder how it will do on the welder. It is a big jolt of power when strike a spark. Let us know if it does better with that mode if it even has an Eco switch. I just looked on the HF website and I can't see one on the 9500 but IDK??
Whoa, wait a minute! The only way that 7 1/2 H.P. Motor is 30 Amps is if it were wired to 3 Phase Power! A 7.5 Horse 240 Volt 1PH Motor would be on a 60 Amp circuit on Single Phase! Check that nameplate and see if it doesn't state 3PH!
I just bought a camper and it needs 50 amp to have it running, im not to familiar with watts, volts or amps, i deff dont want to over or unload it, but want something that can have all my necessities running with no prob, struggling trying to find a generator, any suggestions? Its a 37ft couger on a trailer hitch
any local RV dealer will tell you what you need
Your shop is going to need a 20kw-40kw diesel to run everything
Bingo! My 9500 does my entire house plus 2.5t ac with REASONABLE loads and zero issues. Have a 24kw diesel for shop. U need the big diesel with big gen head to spin up big motors.
Buy another one and make the parallel cord! That should do the trick!
amps x volts = watts. not to mention the extra startup required to get them going.
Only problem I would have with this generator is the 90 day warranty, Harbor Freight is not real confident about it.
Taking this back!!!! Asap
The inductive load of a 7.5 HP motor is too great for that generator. You chose the wrong generator for the task.
Motors have a start up amps, that may go higher then 30 amp at start up.....
Would thi3power a mobile home with a 100 amp service
I'm pretty sure even a 240v 60 gallon upright compressor needs about 13,000 watts for startup
Thats sad , I have a John deere 5500 watt with a 11 horsepower motor and it will run my whole house and 60 gallon industrial air 220 compressor all at the same time. Didn't have my 220 welder at the time or I would have tried to weld with the compressor running too. I may have to try that.
I feel like the machine is nice but has too many nanny settings. The electronics bog it down before its able to do more.
@@G.A.N.G101 It looks cool tho.
@@G.A.N.G101 good seeing a video from yas. I was just thinking this morning I hadn't seen any videos of the competition going on. Haha.
@nopartsgarage6691 joe was sick for a better part of a month and we had deer season to contend with
psarcasm at its finest. Unless of course you want to show the video. I call bs
Dont tease us.. Whats the nameplate on the motor.?! Also. you are starting it with a load any way to dump the load? make sure the tank is completely empty? (although im sure this does not matter as much)
It's a 7.5 horse. Upon further reading well beyond what this would be capable of. However it's still not a great one for the shop. Would probably work fine for a home that never ever moves.
no inverter type generator will handle motor loads on an air compressor and a welder together. To start that 7.5HP compressor would take at least a 27,000W peak 18.000 continuous load conventional generator - maybe more. Motor loads are brutal. I have a 9500 and it runs my house fine in the winter to include a 4000W electric heater in my shop along with the furnace in house, all lights and electronics. Inverter generators by limits of their capacity are not suitable for shop loads. With no other load on them they may start up to about 2HP.
as others have noted, inverter style generators (especially ones with high frequency inverters, which this more than likely has) HATE dead start motor loads like this. low frequency inverters will handle it much better, but they have monster transformers and weigh 3x as much. this is one of those areas were the crossover between generators and off-grid inverters happens, and the knowledge gained from the latter will inform the former.
We've heard that alot about the inverter style ones but we needed it to be able to run sound equipment and a computer. We're going to run a hardline to the power pole instead. That'll be in a future show.
When I saw the compressor I chuckled. There is no way that generator was going to start that motor.
Didn't really like the smaller one even

Lock rotor amps is 3 times nameplate amps
In my experience I've found that Harbor Freight is great for hand tools and consumables but not for heavy machinery. Honda generators are the best. They cost a lot more but you get what you pay for.
A house pulls 3-5 kilowatts, 3 being at low end or when no one is home. That generator only puts out 9kw peak. There is no way that shop uses that little of power. For the price you paid on that compressor. You could have bought a ex military generator off of gov planet that produces 30kw or more. That would be more than enough to run your shop and everything in it. $1,350 right now on their site.
What a inverter generator what's this website you look @
Induction motors can take up to 3 times the amps than the full load rating of the motor. IE a 30 amp motor could take up to 90 amps to start. Check your ratings of motors and surge rating of generator and recalculate .
Great I was wanting to run a tig welder with this after finding out it was going to cost 3k just for the wire to run to my shop
What about the 50 amp adapter cable.
Ahh, gotta love the Chineseum.
A 7.5HP motor requires a minimum of 12 or so KVA to start without a soft-start device - not surprising it didn't run it. You are misleading viewers since you're using 120V devices with the small compressor and the welder. Were they all on separate legs or the same? Also, it shows that you did not hook up the neutral connection with that rigged suicide cord to your building. How about wiring things up properly, using 240V capable appliances at 240 volts, or running the small air compressor on one leg and the welder on the other and re do this?
power = voltage X current. So if the big generator is 240 V / 30 A , that would be 7200 watts. Not sure how you came up with 5800 Watts? But I understand, even at 7200 watts, the generator should've handled it.
take it back and save your money
man that generator is useless.... we always put the air compressor out side...Make a lean to with a closed door on the outside of your main building and put compressor in it and insulate it.... no noise in main building!
Factor load 9500 wattage if you connect the compressor the welding machine lights and other things of course the generator is not going to handle it house hold appliances you put everything together and in case of emergency refrigerator TV lights electric stove and water heater possibly you got 8500 watts is a domestic generator to move your shop you need a commercial grade generator
Did yall follow the break in period? Like suggested
I'm quite sure we didn't. We didn't wail on it or anything
What generator do u suggest?
Not sure? We just don’t recommend this one
Bro did you really show a suicide cord!!?? Male both ends equals death on one end!
I have no idea what you’re talking about
Can you use a regular car battery for a generator and what other kinds of batteries you can use for a generator ?
It just a standard 12 volt battery. I'm sure you could
@JPG23 It's you-tube videos that shows how you can use a car as a generator.Can a 1000cc car battery with a 1,000w power inverter power a electric oven that's 800w or even a 800cc car battery ?
Add a soft start to theses devices. The large air compressor is way to big.
I've stopped quite a few shoppers from buying this item in store. I told them to do their own research & find reviews.
At least with the older stuff, you could fix it with carb cleaner or some simple parts.
I was on the phone with Jackery for hours right after Cyber Monday. I was not impressed with their answers.
Basically, electronics is not the same as solid-state.
