- In this series I take a look at a PowerJack Inverter that I recently acquired and see if it is really as bad as I've heard. They are inexpensive to purchase, but are they worth what they cost?

I love that your videos are super informative and you are able to present it in a very engaging and comical way. I almost kicked over laughing in this one.
I was wondering if you could do a vid where you take an average inverter and upgrade it in an attempt to get better performance out of it? Would be interesting to see what can be done.
Also, i would also like to see a video about inverter safety, not only daily use but when working internally as well.
Just some ideas.
Thanks for publishing :)
You are one of the best out there
2:00
I certainly didn't expect that! Laughed for a good ten seconds. :) thank you for that.
That was brilliant! :D
I'm new to your videos, and had thought that although I liked your content, your delivery was perhaps a bit dry.
Then 2:03 happened.
That was perhaps the funniest thing I've seen in a very long time because it was SO unexpected. Well done!
+Tyler McCracken i am still laughing... did not expect that from him...
Others might want to turn down their volume around the 2:15 mark for a few seconds. It woke up my cat.
Wish I would have seen your post first. My ears are bleeding but It was funny :-0
Omg it scared me
Plus made my day!
Think how loud it was for me with it right by my ear. :)
Mr. Knurl, check your email please.
I have an 8000 watt Power Jack ($329), I think the makers are watching the internet and modifying it as they learn more. Mine has a very hefty toroid coil., they also print the picture of the inside in the manual, encouraging replacement of boards. That's actually kind of cool, since I have blown through $300 inverters that didn't handle my deep well submersible pump (my main concern-1800 watt startup-1300 watt running- kill-a-watt tested), I saw a review on the 8000 watt by an Australian and his had two very hefty toroid coils about 6" across. He showed how to add an inductor coil to reduce it own wattage.. I was prepared to add one but when I opened up mine, the new changes were they had added an inductor coil in the same place the Australian man had shown. So that is why I think they are learning as they go and humble enough to make changes as they see how others improve on their stuff. The other main reason I had to get a true sine (but am out of work and surviving on one paycheck with Hubby) was I figured out the modified sines were killing my refrigerators. I now have several dead refrigerators I am repurposing (solar cooker, water trough, garden storage, barn storage).
The Australian guy on the forum found the 8000 watt he had was able to handle the load, so his was the only review I could find at the time, and I went with it. Honestly, I don't think I will be using more than 3000 watts at a time myself so, maybe no worries for me. If I have my pump running at 1300 watts and a washing machine running 300-600 watts and a non electric dryer running at 300 watts I can be pretty happy.
Thank you very much for your great analysis. No doubt all the folks you've helped have not posted it due to busy lives, etc...
2:05 9 Years later and I randomly sat up in bed and remembered this existed and frantically tried to find this video 😂
Frankly, your take on advertising for Power Jack is probably more efficient than their own.
Legitimately didn't expect that. Haha 10/10.
I've been watching quite a few of your videos over the last couple days which inverter do you recommend in the 3000 watt range I would think Samlex gopower or thor I understand the samlex makes components for both of the others I'm in the process of buying a battery bank for solar for my RV I would really appreciate some feedback and advice
Quite brilliant... fast delivery, very informative, with just the right sprinkle of humor.
But wouldn't you expect the inside to be dirty with that great big fan blowing in outside air?
knurlgnarcan you use a quite tone filter on a modified inverter to improve the sine wave ?
have you seen the powerjack 10 and 15kw inverters on ebay recently? do you suppose that they represent 5kw and maybe 10kw respectively?
I'm building a stand alone solar project for my AC hanger. I really wish you would/could review the later version of the Power Jack 24 vdc to 110 5000 W Pure sine wave inverter the one with the metering panel on the top of the case. From what I can see the construction is totally different from the earlier models, I purchased a used one for cheep with a bad out put plug (the one you hate, I agree it's junk) I do not expect it to live up to it';s rated capacity, however I would love to here what you have to say about it. JM Dier
I just bought a 6000W LF Split Phase Inverter and found that the Charger function is not turning on when connecting a 230V AC 50Hz input to the H line terminal block.The 24 VDC input is also connected while AC input is given. ( Battery voltage is 24.5VDC)
When I contacted the seller (ebay) and the reply is to use 60Hz input AC for Charger mode to turn on
As most of the countires are 230VAC 50 HZ, I am not sure if the input has to be really 60Hz .
Can you advise as what could be the real problem. ?
Read mode
what should be your favorite brand inverter(reliable, price)
.. i have this question about the Inverter Capacity...let say its a 5000w inverter basically i would power up anything below 5000w better if it was a pure sine...but does this mean i need to calculate the input dc voltage also so to not exceed the 5000w capacity connected in parallel..? W=VxA or W/V=Ah... 5000w/12v=416.66666 Ah....is this correct..? ..or can i add more than 4pcs of 12v 100ah battery in parallel..?
Are you still around? I have a 5000/20000 peak UPS/ATS modal like that. can i "jack" up the voltage somehow, from 110 vac to 120 vac - 120.5 vac . LED lights flicker when the laptop charger is also plugged in. Using a "kill a watt" tester, I see the inverter is a steady 110 vac at 60HZ, with or without the laptop charger plugged in. But my home power shows 123 to 125 vac at 60HZ with no flicker and a littler brighter LED light bulbs.
Have you tested the 1500W LF 6000W peak unit?
I bought a Power Jack inverter some years ago. I killed it, twice. My fault though. Two things that I particularly liked is that it used proper heatsinks rather than using the case as a heatsink. Dead giveaway is screw heads along the sides.
It is also quite modular, with decent connections between different boards. 2 small (4 MosFets on each) boards for primary conversion, 2 boards for output power switching. All 4 are identical.
I can't say I much like these HF powerjack inverters, but their newer LF ones aren't entirely terrible. I own a couple and have used them with success. Glad your inverter worked out for you reasonably well. A low price point can cover for some of the sins.
you have circuit diagrams and parts of fish inveter click yourself with?
So what's the best mane brand please I will be relying on one or two maybe more for off grid living
Why in the hell do you think that 4 output transistors can only provide 2.5kw? Have you seen the specs on some mosfets or igbt in to247 capsule?
hey man
im shopping now for a good while for a pure sine inverter
would you advice me in buying one that would worth a shit
im looking at something that can run in my semi truck
i got 4 battery 90 amps each
i have a fridge...vacuum ...and most important 2 ev powered speakers 1000w each
really appreciate your impput
the accent is the same as in sesame street and the muppets-kermit in particular but all the characters. im from the uk but notice quite a few varying accents in the u.s.-so where are you from?
I almost bought one of those, but I just wanted the "Good" one not the "Best" one
I was curious if you have ever heard of In Rush Current Limiters. I have seen a review on Amazon for an Inverter that someone was having trouble running their Microwave in an RV. Someone recommended an Ameritron ICP-20. They said it worked for them. I was curious if this same premise would work for trying to start an Air Conditioner. I have an 8000BTU through wall AC unit on my shed. I cannot get it to run off Mod Sine or True sine wave at 1500 Watt. I tried to procure a 2500 Watt Pure SW but it has issues. It is not a big shed and I did insulate it. I would hate to have to replace a working AC just to get better efficiency but that is looking like a real possibility.
Inrush limiters won't help start an AC unit. Your best bet for your dollar is a larger or more capable inverter, heavier cables, or better batteries. And by more capable I don't mean higher advertised wattage but a better unit. The samlex/cotek SK units for example will easily start that unit. You could also invest in a product like Easystart which work though they cost quite a bit.
knurlgnar24 i am torn between buying an AC unit that is designed to run off of an inverter or generator. They cost a little bit less than an Samlex or cotek inverter. I run 2 12hx505-Fr batteries and a 40a Renogy MPPT Solar Charger. I plan to add 2 more batteries. I have 600 watts of solar panels. It is a good start unfortunately the solar power was an afterthought and my AC was not picked out with solar in mind. What are your thoughts on the reliable inverters. WZRELB ones on Amazon and elsewhere.
Do you think you might be able to do a review on a powerjack 6000 watt LF split phase inverter? I'd love your thoughts and to see what you do with it! (plus I have one lol)
Thanks for the comment. I actually started a review on a Powerjack 20kw split phase inverter half a year ago and never finished it. Your comment may be the encouragement I need to at least release parts 1 and 2 of it. Incomplete and I don't like releasing incomplete videos but perhaps it's better than nothing. yeah, I just need to finish it...
is it possible to convert a modified sine wave to pure sine wave
9:45 The seal is often not removed on purpose, to make it a little more quiet and less annoying, which I honestly appreciate.
I'm not saying the build quality is good or anything. And in my experiences cheap Chinese pure sine wave inverters tend to beep randomly a lot and I end up removing the piezo beeper all together. But you know, at least they try to compensate by not removing the seal.
I often put tape over them myself.
The screaming around 2:00 killed the delivery.
Sound like you could do a voiceover for POWER JACK!!! heh :)
woke up my dogs that was really *JACKKKED UUUP* !!!
you review it like NTSB investigation, I think you'd be able to replicate a Don Smith device..great video
Enjoy your videos very much 👍🏽. Subscribed. Seen your DNA before.
looking at a 8,000 Watt Powerjack what do you think the real output is 4,000 ?
3500W continuous, 5000W peak for motor starting and the like. Generators are rated in a similar manner.
I ran across a PowerJack PSWGT-2500 inverter. It was in pretty rough shape but the price was right. I am trying to bring it to life but I am afraid it might be beyond me. I would pay someone a small some of money to get it going. I am not finding anyone locally. I am not sure if you have ever repaired one of these for someone. Let me know. Enjoyed the video have watched several.
Repairing these is a hobby and not profitable unless you have special access to sellers or buyers. As you know I used them for UA-cam videos for a time but your best bet might be to sell it for repair on eBay. As a repairer I don't see any good deals on repairable inverters anymore so it's a seller's market.
I found a troubleshooting video on a very similar model. I think I have a bad mosfet on the AC side. I may try to fix it. I have another Question. I also picked up accurate tools that works well but is a 220v I assume you can’t easily convert to 110v? That would be nice but I won’t get my hopes up. I have a centech also that is Mod Sine Wave but it appears doa. I got all three reasonable but only the accurate tools seems operational.
Can you review on of the new AIMS inverters?
I haven't actually used any of the newer ones but I do think they are better than they used to be. I'd curb my expectations but give them a shot again. After all the average quality of inverters has fallen so far over the last decade that even these old Aims inverters are better than the new PowerJacks and most other inexpensive Chinese inverters. Sadly, even Cotek and Samlex no longer make all that great of stuff as they have significantly cheapened their products to compete. If you can find one of their older SK designs snap it up! They are much better than the new style.
that was great around 2:15 XD
Can we use it 24h or .......?
I see jumper wires connecting resistors to other parts of the circuit.
CE rated as in "China Export" ;)
The DC/DC board looks like it might have been originally designed for a big car audio amplifier. They typically use split rails. The transformers are small for the wattage since they only have to handle the wattage at a rather low duty cycle. Definitely not the same as 5kW general purpose duty.
so i have a 'broken' 5kw low frequency split phase 24v 120v/240v off-grid pure sine wave inverter... if i want someone to see what is wrong with it - am i going to an electrical engineer?
+Chris Kelly also, it has a nice large, center tap torroid coil. i think the parts are legit. maybe i will video the inside... also noticed all the fuses on your unit on level one, that may be where my problem is.
thanks, good to know!
Hey, it's a Power Fake 5000W.
But if you ask the company they will probably tell you something like "5000W" is only the product's name and has nothing to do with its output power.
Whle back i ask a question on inverter. I did not got the answer. That was? Can you hook up two inverter with the output of a 120 volt each to the breaker box in the house , so you can get 240 volt. If so. How you do it. Hurry please my wife needs the clothe dryer. E- mail the answer please.
Great videos. I have a 6000 watt LF power jack. Runs a 500 watt (5000 Btu) window ac unit 8 straight hours at 105 degrees. Not too bad.
I have an 8000w Powerjack that will drop off line with a 1000w microwave. Original website where I registered the warranty is no longer valid. Anybody have contact info so I can resolve my problem?
With that crap quality, how much would it cost to build your own?
Are these small yellow transformer pulse transformer?
They are transformers that operate in the kHz range. I am not sure if you mean they are Pulse brand or if they are a type of transformer. They are simply ferrite core transformers regardless.
2:10 IM DYING OF LAUGHTER!!!!! XD
+the awesome toaster me too ha ha ha I am from Bangladesh
+junaed Bin Helal nice
@@junaedbinhelal370 bhai amare maira laaa
Has anyone ever said that your voice, timber, and cadence is pleasingly similar to that of the late, great Carl Sagan?
Btw. So far it is nice review. But what i would like to see is Power jack 5000W LF. as low frequency. These high freq. inv will not be able give any surge power. BUt those LF could..So if you can please buy some of those LF inverters and test them. Many ppl are thinking about them. Even power jack is advertising are better option than HF version. Thanks
LF designs are not inherently better at providing surge power as commonly believed. Unfortunately these cheap HF designs give other good HF designs a bad name. LF is an inferior inverter topology that I personally wish would just go away, but unfortunately it is easier to make a 'good' inverter with a LF design without doing any real engineering work so they continue to exist.
***** hf and lf all need good engineering. They are mostly common at providing surge power because there is no semiconductors on the output. Sometimes they harder construct with excellent efficiency.
That remove seal after washing is normal. I expect it is buzzer. and you don't have to remove it. At least we didn't remove it after it was wave soldered and i don't expect it was washed also..that isn't usual but it can be done.
It is a buzzer as you expected, and I de-soldered it later on in this series due to poor design choices on the part of PowerJack.
i seen all your videos even the one about fixing your winter car
2:04 -> If anyone ever wondered why girls don't fall for engineers, haha. Nice review though. ;)
2:11 And that, ladies and gentlemen, is why you don't do drugs.
Capacitors in series divides the voltage by the number of caps in series(or rather, multiplies the voltage rating by the number of them in series). Meaning 120v x 2 in series would be equivalent to one capacitor rated to 240v.
it should be 400v for good performance
+DMAN22yeah Why they should use 400V capacitor for 110V RMS inverter, when they will never see more than 160V on them?
Performance with higher voltage capacitors will be worse, higher voltage = higher ESR, which will give worse performance, shorter life span of capacitors ....
+Miloš Lazović if you have a 200 volt capacitor you will get a bad sine wave, and usually only a square wave
DMAN22yeah
How you will have bad sine wave with 200V capacitor?
I would like to hear your explanation how voltage of capacitors influence quality of sine wave of inverter (I never heard that statement , but maybe something is changed from 20 years ago when I designed my last inverter) especially for capacitors that see only DC current (that capacitors are part of DC/DC step-up converter).
most people who know inverters know that a modified sine inverter with a 200v cap will become a square wave under load. knurlgnar talks about this in his bestek inverter review
sir I watch your inverter video
l want to make a powerful inverter
so plz give me a circuit diagram and full detail about it
Do a 2020 review on the 2020 power jack inverter
I expect them to be much better today than back then. I may do so in the future.
lol. greatest inverter review ever.
Hey I have all the guts out of a very large 12 volt inverter there is nothing wrong with it I just needed the case for a 48 volt inverter I ran a air conditioner in my RV with it among a lot of other things very strong 12 volt inverter like to see you do something with it
Lol @2:11. Good stuff.
I just got a 3000w modified sine Wave inverter and mine says best now we can't call have the best
looked clean enough but that seller is not cool at 14 would have used jb weld at least to hold wires in outlet so not to touch
I 'WUV YO' Videos.
Would You Ever Put Together a 2000w-5000w PSW Inverter Simple, Practical, Heavy Duty, Clean, Indestructible & Inexpensive, for Us 'Poor Folks!' Your Humor Just Gets Better & Better. I Own a 'Tiger Claw 1500w PSW & Liked Your Video On It. My First Inverter was a POWER JACK 2000w PSW. It Ran My Skill Saw. I Just Bought The Inverters to HAVE & Never Used the TIGER Claw. Looking For The 'Knurlgnar Custom Inverter' That KICKS ASS, is CHEAP & UNBREAKABLE & Super Clean! Thanks!
this guy is such a party pooper
so this brand of inverter are inverter/charger
Wow. That was LOUD. PLEASE don't do that ever again. You'll hurt someone else's ears. Not mine of course, because I'm out of here.
Snowflake can't take a joke
POWER INVERTER 5000! ITS THE BEST!!!
On the Avasva you can count on professional help with problems and technical support.
yaaaaaahhhhhhhh............ well moving on, LOL
Comperato dopo 2 mesi si è bruciato non a retto a un carico di 4000 watt,senza andare in protezione.il rivenditore non mi a mai risposto,per ripararlo costa quanto nuovo.sconsigliatissimo
Why yel?
WTF happened on 2:04? .-.
2:30 thx to my Limiter my Headphones did survive...
nice
Can't believe this unit will not even boil a 750 watt kettle with 2 parallel wired deep cycle 12 volt batteries...
I would rather honesty and be required to buy 2-3 of these than buy one and having it burn my house down.
mad , why make shouted power jack as a giant.
ow my ears at the screaming i had headphones on
I am having issues with my unit. Never worked and will not even power a 5 watt LED desk lamp without an alarm. How could I even run a house, or fridge. it was to have a warranty, but evidently they do not support what they say. this never worked without an alarm going off. show me the video on how to stop the alarm. David from PowerJack has ignored me. sent many videos but he fails to provide a solution. DAVID, SEND ME A WORKING UNIT!!!!! Maybe you can't remember me form the thousands of other complaining people.
Hi from Xantrex. Love your channel, have been viewing for about a month. Love to have a chat but unsure how to DM via YT comment. Email our Webform? Ask for WT.
I will never buy a high frequency switchmode inverter again.
they are good, just not this one
That`s scary, well ya get what ya pay for.
HEADPHONES!!! Ack!
thanks for the blown eardrum
In 240volts

Please never, ever do that loud screaming advertisment. That killed my ears due to the fact i was wearing headphones.
pretty much a "power Junk"
LOL, So if you buy a 12,000 watt for 50 bucks you would get a 6,000 watt inverter, lol.
You said you would tell us where to find schematics, I wasted the time to watch this video because I thought there was going to be a link to schematics.
Downvote for raping my earballs with no warning at 2:11. RIP headphones users.
First!
(heh heh..)
Knurlgnar24 is there anyway for me to get in contact with you as i have many questions to ask and you seem to have a wealth of knowledge!
Joseph Thorneycroft
you can try sending me a PM. It sometimes takes me a while to reply but I do try to.
***** Okay thank you i have sent you a PM
***** Your problems with the Power Jack Inverter have only just begun. Read this blog by Ludens: ludens.cl/Electron/chinverter/chinverter.html. He did a massive amount of re-engineering to prevent electrocution issues, RF interference issues and DC regulation issues. I am very surprised that your Power Jack actually works as well as it does or even works at all.
***** Hi Knurlgnar, I love your videos! I am looking at Surveillance Vans and how they manage to run a 8000 BTU Air Conditioner (880 W, 115V, 8.0 A) on batteries for X hours while on pure battery power (no solar & no generator). In Surveillance Van build documents, they recommend 2 x 8D AGM batteries (each has about 200 Ah) and a 2 KW inverter. An RV or Van should be able to carry these batteries (160 lbs ea). But, I am really not sure just how long this sort of Air Conditioner system would run. I carefully watched your wonderful videos but you did not really show "how long" your big 1400 bank would run stuff. Please help me with a battery needs calculation. With AC, I guess you also have to take into consideration a thermostat and what if it is running about 50% of the time (cooler day) to maintain 72 degrees but I guess we also need to calculate 100% run time too (for a very hot day). Not sure. Any help you can give would be greatly appreciated. Thanks so much! - Aprille
