I must admit, I grew up in a TV repair shop and in my entire life I have never heard microfarad pronounced that way. LOL
G56AG 😂😂😂 "micro-farts"
Lol
I bet that AC unit pulled around 20amps peak trying to start compressor. As soon as the generator saw that surge, it kicked into safety shutdown.
Hi Ottis Good Video,
First I never heard before of changing to use a larger "starting capacitor." So I learned something and will keep that in mind.
Some reasons why you didn't have success THIS TIME.
#1) Your Invertor Generator has a switch labeled Eco-Run & RUN.
Invertor generator Mgfr manuals state DO NOT attempt to run Refrigerators or Air Conditioners in ECO-RUN setting. Always run them in RUN mode. (Why? Later)
#2) A Kill-A-Watt meter can only measure the AVERAGE CONTINUOUS POWER used over seconds, minutes, hours etc.
It does NOT display the instantaneous ELECTRIC MOTOR START UP SURGE POWER required drawn in the first fractions of a second (typically drawn in the first dozens of thousandths of a second).
#3) EXAMPLE: An electric motor that draws say 400 Watts running, may demand an instantaneous SURGE starting wattage of 2x to 3x time the running 400 Watts or an instantaneous SURGE 800 W to 1200 Watts. Thus in the latter case exceeding your generator.
In a below video one guy reports the 5000 BTU A/C draws only 350 Watts on Hi-Cool. So an estimate the startup surge power of 3x 350 W = 1050 Watts SURGE required for an instant. But that is within the capability of the generators 1000 W surge and 800 Watts running in the NORMAL RUN MODE.
#4) BUT YOU DO NOT GIVE UP.
Other Guy'es Internet videos are demonstrating running a similar 5000 BTU A/C off their small 1000/800 Watt generators. (I've included web links to them.)
#5) (The Why? Later) - ECO-RUN vs RUN
The RUN setting runs the generator at FULL SPEED thus is continuously able to supply 1000/800 Watts in an instant, but uses the most gasoline. Like running at 70 mph full time.
In the ECO-RUN the generator is measuring the power wattage being drawn and thus varies the speed of the generator to produce it. So if the A/C only requires 400 Watts the generator will run at a slower gasoline economizing speed than it would to supply 1000 Watts. But if more power is drawn, the ECO-RUN will speed up the generator.
The problem in ECON-RUN the generator can't instantaneously increase its speed from supplying 400 to 1000 Watts and the generator. There is a DELAY, equivalent to going say jumping from 30 to 70 mph. This delay resulting from a large power swing may cause the generator to stall. Also some people report the ECO-RUN delay resulting from the SURGE running electric motors "may" damage the electric motor.
Good luck with your repeated experiment.
I hope my explanation helps.

I give you credit, you don’t show your frustration that hard. I need to find one too
Did you say, Micro-farts? Well there is your problem right there..
500btu is only about 500watts. I run mine in my camper on a car battery and a 750w inverter. Marine deep cycle battery. Lasts about 25 hours straight. Went ahead and hooked it up to a thermostat outlet so it turns on and off automatically so I don’t freeze to death from it snd it also conserves energy. Then I use my generator to charge the battery if it camping for a while otherwise it has a very small solar panel that charges it full over about 3 days
Funny comment.
Every truck driver could use this set up.Takes a ge 5050 btu and a hard start cap. Uses half a gal gas for 5 to7 hrs use for ac only.
Heck yeah, buddy. I wish I had known this stuff back when I was driving. I spent quite a few hot nights with just a fan sleeping in my rig.
My sportsman generator 1000 watt shuts off as soon I start up my 5000 watt portable generator.
Sorry Mr. I have seen some others pulling it off with the same set up. Either the cap is not on the right plugs or it is too small. Maybe they should install an option from factory to start it with a crank like old cars used to be. But don't give up. It needs a lot of juice at start up but only for maybe a second the max.
STRANGE!!! My 1000 watt sportman on econo mode runs my 10 year old 5000 BTU A.C. ... MY Friend has same generator no issue whatsoever.... You may have faulty generator.
I am thinking the same thing.
He does have. Faulty generator no doubt about that.. I hope he found that out.. the gen should and run 2 of those 5k btu maxed out this is crazy
@@vanhogan2179 im running a 5,000 btu ac right now with my powersmart 1,200 , 1,200 max 1,000 running watts
Great chair!
These generators are a con 2 versions 800w & 2000w come on all different makes & colours but under the side panels there all the same thay are not the watage as sold,I can't even get 400w from a 800w with the 1000w Serge.
There are quite a few people running the 5000 btu ac on these generators. I think you need an AC that comes with the built in capacitor. The others on youtube haven't had any problems
Not all ACs are created equal. I tried a new GEN1000i with two new 5000BTU ACs, both purchased at Menards
:
- Cool Living CL-RAC05MW
- Soleus Air WM1-05M2-01/02
I was completely incapable of starting the compressor on the Cool Living. The Soleus would start only
if I turned economy-mode off, then started it in fan-mode, then instantly moved it all the way to low cool.
Any other procedure killed the genny when the compressor kicked on. I then installed an SPP5 start cap. It
helped a lot, I can now start up the AC without special procedures and it even runs in economy-mode on low cool.
I went for a fridgedaire 5000 that others have had success with. It works but you have to switch from fan to low cool to high cool slow at initial start and let the gen adjust even with eco mode off. The generator speed needs time to adjust even with the right air conditioner. Not all ac will work, only certain ones designed to have a low surge startup.
@@jimbob3030 my buddy powers that ac on low cool with the generator on economy mode..
He puts it in fan mode.. Lets the generator adjust then switches it to low cool... All with the generator in economy mode.. It must be on gas... The generator can not do it on propane
He learned it from HoboTechs channel
Yeah it’s kinda hard to get around those laws of thermodynamics
I’m surprised it wouldn’t run it great video
My friend do this all their time on their VWbus when we go camping. A/C in their bus with inverter... works fine.
Thanks for the video :)
Try an extension cord Active Start $485
The Frigidaire model in the other video has "soft start" capacitor from factory.
im waiting to find one like that on sale
What the world needs is a
What the world needs is more educated people and not pie in the sky dreamers that rope other people into wishful thinking. My 1994 Honda Accord's factory AC was a 22,000 Btu/h capacity unit. What makes you think you could take 200W, which is at best 682 Btu/h at 100% conversion efficiency, and cool down a car? You are literally suggesting a violation of the conservation of energy. You achieve what you say, and you will be richer than Elon Musk. I don't know who Cool Breeze is, but they sound like nothing but hot air, and that's not cool.
Unless one is in the dry desert that swamp cooler will not work.
@@richarda996 Amen, Richard. So many folks have been hornswoggled by this scam here in South Florida that it's sad. No one paid attention in Jr. High when they talked about relative humidity.
It’s about 900w max and 740 running. Make sure eco mode is off.
Try removing and cleaning the carburettor. Pay special attention to the idle air ports. They are microscopic ports near the butterfly. You may see only one small port or as many as 3 in a cluster just near where the butterfly closes.
Remove the idle mixture screw and then clean them with carburettor cleaner spray and an old accupucture needle. When you see them spray carby cleaner through them you know they are clean.
Note these ports run off from the same hole that the mixture control screw is in. You will see a port that runs forward toward the butterfly if you look in the mixture port hole after your have taken the mixture screw out.
I have had a generator do exactly what yours is doing when trying to transition to power under sudden load. The engine can't do it so it drops speed and the inverter decides it is low voltage so the engine stops to protect the inverter.
I could not start a simple fridge with mine but it would run a 2000w heater. It was also hard to start.
Once I cleaned the idle mixture circuit it was perfect.
The idle air and mixture circuit is responsible for ramping up to the main jet circuit as well as idle speed.
This circuit gets blocked from New often but is very susceptible after long storage and old fuel.
Best of luck with your adventure.
You are asking a lot for a 1kva unit.
Those meters dont show peak starting watts. I have the same ac and generator. My clamp on meter spiked at 20a and the killAwatt dosnt even show a spike. Mine dosnt run the AC either.
One thing I found out and thought about on these little suitcase portable generators do not take any of the panels off when it's running. Some people do this in UA-cam videos but I thought about this. this is a bad idea or to drill holes in the side panel this is a bad idea also. These small suitcase portable generators usually suck cool air in through the front and blow it out the back like my Sportsman 2200 watt dual-fuel suitcase portable generator does. I think this little 1000 Sportsman sucks in air from the bottom and blows it out the back. They do it with a fan they have in there so the whole engine and Generator will be cooled down. When you put a hole in the side or leave off the panel it will not let the air go through as good at all. And this could cause an overheating problem and lead to early failure. Why the guy did this is because on his suitcase portable generator when it was running and he took the little oil cover panel off he said air was rushing out trying to escape. That is true but air is being pushed through the generator like a tunnel effect. It's like drinking out of a straw if you ever get a hole in a drinking straw you can't get in as much efficiently with a pin hole in the side of the straw. I know what this guy is thinking by putting holes in it or some guys leaving the side panel off the generator. but this is actually hurting the generator and taking years off the life of the generator and it's making the motor run hotter. The only way I would ever believe this is if someone did this test which I may do some time to prove it makes it run hotter is measure the exhaust gas temperatures out the back of the generator at the exhaust pipe. But personally I would not want to do it on my own generator if I did I wouldn't do it for long. It's like taking the fan shroud off of your car's engine. On the bigger open Panel generators that are loud. putting a fan on the generator would be fine and would help it out on the hot summer days or running for a long time.

You useless long winded dip shit.
@@gingerbread1032 🤣
Only issue I ever seen or heard of was the 5000btu a.c units WITH DIGITAL CONTROLS.... Checking with about 6 others No one came even close to a 600 watt surge. Of course I start generator in full power.. AFTER running a minute or so I then turn a.c. on low fan first about 30 seconds then high fan 30 seconds...then switch to cool...compressor kicks on let generator run a while till a.c. cools down area then i swith to econo mode....Very very strange i say again..theres no special easy start capacitor on my a.c.unit... I even was ablle run on my old vintage Honda EX600 Generator rated at 450 continual and 600 watt surge..I Only let run about 2 minutes and i shut off because thats pushing little ex600 honda too much..
I wish they made a decent 3000 btu window unit.
Set the Sportsman generator to Economy OFF, and then re-start the generator a couple of times. I had to do the same thing with my mini-fridge.
I do voice command I talk and it prints it out for me it's so much faster. I'm going down the same road I just ordered the smaller 1000 Sportsman yesterday. And I plan to run a new 5000 or hopefully a new 6000 RV style window air conditioner also. But I'll have my work cut out I plan to run it on propane which you lose 10% of power. I think you're speaking of hobotech I watched his videos closely. And talked with him through the comment section. Thinking about this he ran a brand-new frigid air RV air conditioner. I also took a picture of his video that give the part number of the AC he ran if anyone needs it. The Frigidaire air conditioner hobotech said which had the soft start micro air built in it from the factory he said. if you look at his videos he leaves the part number for the 5000 BTU AC. Like he said and this is true in racing and engines the thinner your oil is the more horsepower you make on the technical side. I would just go back to 10W30 oil if you live in the cold climate for the winter time. I think the thinnest oil I saw at Walmart was like 10W20 or 5W20 0W20 is about the thinest. Also in a big air compressor gasoline powered I have it always helped to make the motor start up easier whenever I changed just the oil for some odd reason. Maybe because changing the oil was removing the little bit of gasoline in the oil because it's a gasoline powered air compressor. And gasoline will get in the oil from any gasoline powered engine eventually. And at some point I've got to change it over to propane. Running on propane the motor will last two to three times as long. The spark plug and oil is always super clean just like brand new running propane. propane is very dependable never comes out of tune and never gives all the hard to start carburator and problems. Here's something else I did to my very old non digital home air conditioner when I was almost ready to replace it. I thought I'll try this one last thing before I replace it with a new one. I have a big I think around 12,500 btu x 110 volts alternating current very old air conditioner. I bought it brand-new new years ago. And luckily never had to do any work on it. What was happening the cord was getting warm and that's very dangerous that can lead to a short or possible fire. And it was getting very hard to start up with the AC Plugged In The Wall. Even shutting everything off on that breaker it was blowing the breaker just trying to start the air conditioner alone. So after replacing the breaker that still didn't seem to get it and making a very thick extension cord that still wasn't doing it either. So I took the AC apart and blow it out with the big air compressor I have and it's right at 205 lb of air pressure more than most out there. I worked with Ingersoll Rand technical to dial it up safely several years ago. I really thought this will never work to fix the air conditioner problem. but this is the last thing before I just go out and buy a brand new air conditioner. After blowing the air conditioner out for about an hour or hour and a half and putting it all back together and putting it back in the window. I come across something I could not believe it worked. The AC started up like new with no problems and not getting the cord hot or blowing the breaker at all better than ever. Because I was ready to junk the air conditioner if that did not work that was the last thing I thought to do. It was no longer getting the cord warm and it was it freed up so much power. I could even turn on my overhead lights on which is about 800 watts total 8 x 100 watt bulbs each. The AC worked fine after blowing it out with compressed air I could not believe it. No telling how many air conditioners just like mine got thrown away when all it needed was a good cleaning blowing out with compressed air. I could even run the air conditioner with the 800 what lights on when starting up the air conditioner. After cleaning it out the air conditioner. Also if you're trying to do like this video is doing the easy start micro Air I think it's called it sells for about $320 on the doorstep. it's a microprocessor a soft start micro air actually it's called. And they use them on the big 13,500 BTU RV roof mount AC running a 2000 watt Honda. And that's very fuel-efficient but the Honda has about 16.3 amps the Honda 2000 model does. But at Honda and customer service or technical they told me you cannot use 16.3 amps the whole time.OR it will kick off into overload. It will run 15 amps solid it's used for the extra 1.3 amps for starting AC's and stuff surge Watts. And Hondas have a bigger engine which burn more fuel but they are a good generator.
Can you repeat that?
@ John Smith- Can you repeat that?
The initial start uses alot of power once it warms up it uses less power
What you were looking for in 2018 was a soft start system. :)
so just recently i bought an "energy saving easy start" unit that still stalled out the generator. point me to a "soft start system" and ill give that a whirl. currently im borrowing my son-in-law's much bigger generator which i don't like lugging around...
@@ottisthedog3544 I recently bought a Craftsman 3300 and all I had to do was adjust the idle scew with no load on the generator to raise the RMP. Once the ac kicks on the rpms will drop. This works out pretty well.
The truck is finding the Lowest RPM that will allow the portable ac unit start.

Looks to me like what ever it is that you smoke every day is a bust !
rugerron67 too much of that "micro-farts" and " kill-a-watt"😂😂😂
Do you think a 1500w/1200w generator would run a 5000btu AC and a small rv fridge, both at the same time ?
i think the 1500 might if its a good one like a Honda. you would really be pushing a 1200. but it depends on AC and weather or not its a "soft start" and the same for the frige.
Has many watts
The Kill-A-Watt may not have a quick enough sampling rate to catch the actual spike. But its that spike thats killing it.. The capacitor should have helped, maybe it didn’t charge completely or maybe something is wrong with it or hooked up wrong.
Pine to puke RMS is more & not seen.
Also, don't put the generator on eco mode. When starting AC start on low first then high. Turn off eco mode to let generator run full blast while starting the AC compressor
i have the the brown tan version of that generator and it was able to power my 5000 BTU air conditioner
It doesn't anymore but it did there for a while
always nice to have the good lord drop by!
Quiet?? Buddy I think U need a decibel reader!
I run a Midea -5k BTU eco mode off. No problem. Low fan then low cool then high cool high fan Same generators . Will try my LG 5016 next after it's oil change.
the more i see the more i think (and have heard) that not all these generators (like mine) are the same, some pull better than others. i may have gotten a weak one. let me know on the LG 5016!
That is awesome! It's what I'm looking to do. How long does a gallon of gas last?
a tank full (less than a gallon) has run for 10 hours but it wasnt running a lot of stuff. battery chargers, led lights, xbox for a few hours. i fill it with a 5 gallon can so im not sure how much it holds
Would a 2000 watt inverter generator work without a capacitor
Yes
Just need to get one ! Five to seven hour run time on a gallon will get a deep freeze frozen and good till the next day cheaper then buying ice at the cabin ! Just freeze a crap load each day for about $10 !
i have a cabin in the UP and yes ive seen mine run for over 10 hours in eco mode on a tank full. granted it wasn't pulling anything but a CPAP machine and a few lights (led at that) but we were dumb founded.
Never seen a generator actually shut off when overloaded, usually they just throw a switch.
Bro 1000 watts wtfff that’s my growing light an that shit still run up my bill in never using my AC again
The generator is not enough near the 200watt when the fan on the watt drop pretty low get a different generator
Keep trying dude you'll get it sooner or later interesting video .
Need a soft start for the air conditioner
Oh my God this is so funny I used the exact same chair for mechanicing people laugh at me all the time about my child's chair
i love my chair it is indestructible
If my computation is correct, a 5000 btu is 1.96hp is 1461 watts. I don't know how your 1000w generator can power that 2hp aircon
ive seen honda's do it and ive seen these do it if they are a "soft start" air cond
A heat pump just moves heat around. The 5000 BTU/hr rating is the amount of heat it moves, not the energy required to do so. Most small air conditioners have a coefficient of performance (COP) around 3.0, meaning that they move 3 times as much heat as energy required. That's approximately what the meter shows. The important figure that it doesn't show, however, is the peak amperage used in the first few tenths of a second during startup. To measure that, he needs a better ammeter.
@@ottisthedog3544 what is soft start?
@@davidgarcia-mo4ob its one that already has a capacitor built into it much like the one i tried to put in only properly matched for the motor
Amps buddy it pulls to many amps than that little gen can flow
I guess somebody has to figure out some btu n watts!
Your meter is in kilowatts
Okay 👍
You can buy a relay that will delay on start. Hook up the fan through it so the compressor starts first and a few seconds later the fan starts,. That would be about a 10% improvement right there.
I'll look into one of those Thank You
Your "Kill A Watt" dosent measure instantaneous amperage. You need a special meter for that. Turn off the eco mode also.
Micro farts yep that's the problem for sure . Thanks for the review of that generator!
i even bought a "soft start" 5000 watt since and it wouldn't run that one either. good thing the son in law has a bigger generator he lets me borrow for camping.
Im quite disappointed in my Sportsman Generator,... Mine doesnt run what it should & my $89 Harbor Freight 800 watt 2 stroke generator kicks its ass.
Yeah, me too. There's definitely ones that produce close to the stated watts and others that aren't even close. Sounds like you got a junk one like I did. Mine goes off economy running a simple 75w box fan and dies instantly trying to run the same 5000 btu a/c others have success with. I talked to Buffalo tools this week and a replacement inverter is $72. (I'm out of warranty), so I'm debating trying that.
Update: I also tried adding a hard start kit with no success. But, the generator went on sale again, so I bought a second one fully expecting it to fail also. To my surprise, it DOES run the same AC unit that kills my first one. I tried the first one again . . . still dies. Also, the new one will run a box fan on high without going off economy. The first ramps up just a bit while running the fan. That might be quick way to tell if it's putting out what it should.
Lol
O sheet foo
You know it only draws 400 watts you can run 2
If the running power is 380W. Multiply that by 3 and you get 1140W. Your generator with a surge capacity of 1000W will not handle that. You "75 micro-fart" capacitor is just a joke. You find 2500 micro farad capacitors in small amplifiers. What will work in this case is to connect car battery in the place of that capacitor with some thick enough cables, or you get a super capacitor from a microwave oven.
thank you thats the most useful information i have received to date. the multiply is something that i can understand and apply to other things.
What you need is a:
Soft Start Kit
~$300
or
Hard Start Kit
~$40
Ok Ottis - time for some basic math energy/power conversion education for you and your readers. Your 5000 Btu/h AC provides 5000 Btu of cooling per hour. This is, in thermodynamics and general physics realm, a unit of thermal power (Btu/h, where Btu is energy, and you are delivering or processing this amount of energy each hour, which is by definition, power). There is a simple conversion of thermal power to electrical power. The conversion is 3412 Btu/h = 1-kW of electrical power. So, your 5000 Btu air conditioner, if delivering 5000 Btu/h, requires 5000Btu/h divided by 3412 Btu/h/kW = 1.46 kW, or 1460 Watts. Now, keep in mind that your AC is not 100% efficient, and therefore, the electrical power of 1460 Watts will increase due to inefficiency. So 1460 Watt is lowest possible power draw, on average, to provide 5000 Btu/h of cooling. That is just the steady state power required and it exceeds your generator by 50%. We have not even spoken about start-up current the AC compressor requires, which is a big transient of power beyond the 1460 W and your generator's capability. Your generator never had a chance - poor thing.
OMG thank you! finally someone with some math! i see guys on UA-cam running these small AC's on this generator, but i never really trusted it. i didnt feel the generator pulled down enough when they turned on the AC.
@@ottisthedog3544 I'm not sure what's going on here, but I've seen a 800/900 watt gen run a 5000btu a/c
Michael, the mistake that you're making is conflating heating and cooling. Sure, to _make_ heat at a rate of 5000 BTU/hr, you'd need ~1500W of electrical power. But to _move_ heat at a rate of 5000 BTU/hr requires much less power. You were on the right track when you said "your AC is not 100% efficient" but in the wrong direction. Compared to a 5000 BTU electric heater, a 5000 BTU A/C or heat pump is way more than 100%. Not magic, just that moving heat is more energy efficient than creating heat from electricity.
So why doesn't it work? Well, false economy is a thing. Couple a cheap window A/C unit with a cheap generator, and wishful thinking only takes one so far. Adding another random capacitor to the properly-sized starting capacitor isn't going to do any good, and may make things much worse. A soft-start kit is likely to cost more than the A/C unit, but will at least work.
IMO the best solution is to get an inverter A/C unit that varies the compressor motor speed to regulate temperature, rather than turning on and off over and over. Soft start is built-in. I don't see any at 5000 BTU, but the 8000 BTU Midea U unit provides 60% more cooling while drawing only 700W. At the lowest setting it only draws 200W, so the 800W generator could power other things. At $400, it's twice as expensive as a normal 5000 BTU window unit, but offers lots of benefits to justify the cost.
All points well taken. being the "cheap charlie" that i am my attempt to rub two nickels together and get a quarter failed... i really like the inverter one. looks like LG makes one also but they refer to the inverter as a Dual Inverter so i am curious as to what "Dual" means exactly. its a LW1019IVSM its a wee bit smaller (im dealing with limited space) but more money (cheap charlie (who generally pays more in the long run)). im gonna keep looking but im finding the Midea closer to $300 but not under so thats my mark. the first one i find for under $300 im buying and trying! (including shipping of course!).
thanks for the post
@@ottisthedog3544 I had a look around, and apparently the LG units use a dual-stage compressor. One stage is optimized for low-RPM operation, and the other for higher RPMs, sort of like how some turbo motors have a small one to be responsive at low RPM, and a large one to deliver more boost at high RPM.
I first heard about inverter window units (I have an inverter mini-split at home) from a review about the Midea U model. Midea is an appliance OEM for several brands, and LG is huge. You can't go wrong with either brand. The main concern is getting a unit that won't need a bigger generator. Good luck!
I watched all the same videos of it working... bought the same generator with the same results you're seeing. Talk about disappointing.
one of these days im gonna buy a "soft start" AC unit and try again.
Man, as bad as I wanted to give you a thumbs up for trying, I just couldn't, & found it hard to believe that you would do a vid on something you have NO inkling of what you're talkin about!
