Holly bananas! Never seen cells that size before! Great build. The thing about DIY is you can fix it if it breaks and every time you see it, you know you made it and pride washes over you... That's priceless.
We have used the ruclips.net/user/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!
The sunken cost fallacy is when you have invested too much into something and are reluctant to admit it was a waste of money. If you were only motivated by the amount of stored energy, you could have almost bought two and got twice the energy for what you put into it. But the the experience you gained and the public good of education generated for your audience (who cannot afford to buy foot long batteries) is priceless. This one could have gone either DIY or buy. It depends on whether having extra power was your only goal. Loved the video. Power independence is a favorite topic.
Nice build! Tech tip: Do not drill all the way through plywood - it will split on the other side. Drill a little from one side and as soon as drill bit starts to poke through - drill from the other side.
I seem to recall from shop class 100 years ago that you could also put a piece of scrap wood on the other side and drill through and into that to help prevent splintering. I might have hallucinated all that, though.
@@electronpath Yes, that's an important detail. A small piece of a quality 2x4 worked well in many cases, IIRC. You can drill straight down into the two on a solid surface or clamp it on if you can't lay the work flat.
It’s not the DIY or the buy who wins.. YOU win every time .. I studied electrics, but I can’t declare myself as engineer with your existence !! Stay creative and we love you!!
Hey there. Nice to see you working on a portable energy source, since I just started to work on a similar idea. Good you already payed the 500 bucks to look inside one of those commercial units, so I won't have to do that anymore :D. Just kidding, great work as usual!
REAAALYY Stretching the word portable on this one. I challenge you to make another build but this time keeping the size within 160% of the comparison Power station and adding more of the same ports and features.
Diy is always the winner in my opinion because it's built with the users purpose and specs in mind. Next time instead of building a case, try and find an old computer case or other junk item to repurpose for the case to save time and money.
Great job! I vote for home built. I finished my battery compression box the day you posted this. The unit is up and running daily. It has 560 amp hour EVE cells, 3000/6000 surge inverter, 250 amp BMS, 30 amp MPPT, 75 amp on board lithium charger. It was built to run a big refrigerator and 2 chest freezers on 120 VAC power. We lose power more often in Northern California these days. Last year it was only out for 47 hours in August here, but much longer elsewhere due to wildfires and terrible winds. Its in a steel tubing cage on caster wheels but at 51 kilos, 130 pounds, its not portable. The 410 watt panel sits temporarily on the roof on the foam they shipped the cells in.
I think you identified the main problem with power stations you buy - they try to do everything and they cost a lot as a result. In reality, as you have shown, everybody's needs are different - You want USB and mains output and don't need 12v. I need 12v and USB but I don't need mains. I've just finished building my own power station which does what I need and no more. Cost me £120 - with the greatest savings being not needing the inverter and the cabling and larger batteries that go with it. DIY is definitely the best option.
Great video! I did exactly this last year only, instead of charging from a wall outlet, I mounted a 100W Renogy solar panel to the top of the enclosure and included a Victron charge controller to keep the batteries charged. My setup was comparable to a Goal Zero model that costs several hundred dollars more and doesn't even include the solar panel.
I am a structural engineer who recently discovered the miracle of PL premium and PL Premium Max... also Loctite branded versions. If you used it in all your connections of wood to wood it the wood will break before the glue does. It is super cheap... bonds to most materials... but it wont come apart ever.
I fit the wood parts dry, apply PL from the 4 oz tube, hand position the parts and pop a few air driven brads into the joint at random angles. The stuff is amazingly strong. Pieces go together quickly.
You certainly could make it look better, you could make it look like anything you want - to be honest. It depends on who's making it and who you're trying to impress 🤣
I mean he has a lot of tools including a 3D printer, so he could've made something much nicer looking if he wanted to, I assume this was just the result of any project that doesn't come out nice, mainly time/laziness.
At first I thought the reason for bringing portable power source is to charge your phone or use it for some low energy applications but the answer "bring out the jigsaw for an emergincy wood cut" got me there
Nice build. I did the same thing without an actual enclosure. I used a 1/2 inch wide plastic cutting board and mounted the inverter on one side and the charge controller and DC connectors on the other side. Its relatively light and portable. The battery is separate and must be connected to use. It is pretty much a small solar power system that can easily be transported in the back seat of your car.

Not a bad build! I used a toolbox, and small 32650 cells all spot welded together for mine. It’s got 2000ish Wh, but the same 1000W inverter. And I used a solar charger controller instead of a buck converter to charge... but I TOTALLY agree, DIY wins hands down.
Well done Scott. Very nice project. One improovement could be to add fast fuse between an inverter and the AC socket because this type of inverter doesn't tolerate shorts on it's output despite what user manual says.
I love how you excluded build differences between the DIY and the BUY where the DIY is a chunky big wooden box on wheels, while the BUY is a compact and carryable unit. Haha! All in on that Wh/eur!
Tip for soldering bucket ring terminals: hold with vice grips or vice, heat with torch, fill 1/2 way maybe 3/4 max with solder while still heating, dunk wire in solder, hold 'til solid. Perfect solid connection, though do remember the solder can, as always, wick up the wire thus strain relief is always a good idea.
Tip for soldering wires together straight: put wires together end on end, turn them about 45 degrees from each other which will allow you to wrap them around each other, creating a better mechanical connection before soldering as well as a perfect clean joint that you don't have to hold while soldering. Solder then, be happy. Called a western union/lineman splice.
Awesome Video :D yes the other was 500€ and DYI was 970€ so you save maby around 30€ with DYI and *2 the Power aswell and the fun of making your own that can be made for portabel in a car Camperwan etc :D the 500€ i guess is nice for the design&Size :) Maby next video you try to make the box small as possible and maby in aluminium case with Grounding+Safety with grounding :D
kind of like buying a big box store PC vs building.. you typically spend more but your component's are better and probably last longer, plus performance is typically better. I dig your build, I have a bluetti AC200 but I think with the battery options now, BMS, shunts, I probably would've been better served with something that I could replace everything myself vs all-in-one. Awesome video as usual.
You were creating A.C. in the old video, fine... but your tesla coils were not good, the arcs were too short/ the circuit was too complicated(compared to slayer exiter). I tried experimenting around with other "bjt" and could reduce the size of the senondry coil to 7cm and diameter 3 inches,wire used about 34 AWG. Primary coil is the breadboard wire, 1 turn. but i got a decent hot arc length of about 1.5 inches and could light up a cfl without being touched to the coil. (atleast better than your part 1 tesla coil). for that i use mje"3055" NPN transistor, 22 k resistor and 12 v(1A). power supply. maybe you should try this or use a zvs circuit, the induction heater you made(for primary coil) for a full sine wave A.C. inverter. You might find it interesting.
A really cool project. Just saw one of those 4KWh solar mobile charging packs earlier and wondered if one couldnt diy it. When paying 3-4k bucks for one of those there sure might be benefits for DIY. Assuming one doesnt burn the house down with it at least.
I have done a price analysis on building a DIY power wall - and in terms of the price per Kilowatt it is right on par with grid power usage fees! Which begs the question; why aren't more people DIYing their own power security? Great build! The laser labeling is a very nice touch too.
I had the same dilemma, but ended up buying the same portable power station about a year ago. I want to build a larger unit someday. Thanks for the video.
I like how you need an emergency jigsaw while camping, just like how Jason would need an emergency chainsaw while camping, he he. Great one Scott, I love those batteries, must say. I would love to see you build an electric motorcycle someday, one with a sidecar full of batteries.
Very well done, for the full 1kw of continuos power I would have used a set OFC 2 gauge wire, it is still extremely flexible and soft bit would allow for proper transfer. 85 amps continuos through 8 gauge seems a bit weak. That is my opinion however and I build for the extreme as well.
I built 2 basically one is 585 watt hour with a 500 watt inverter an the second one I have the battery built with a 1425 watt hour battery and am trying to get a good 1500watt inverter that fits I have tried a couple but they can't do what I need
Watch out. You will get hooked on this stuff. My latest home made power box is 7200 watt hours, 560 amp hours, 3000 watt inverter with 6000 watt 20 secod surge, 75 amp onboard charger, 30 amp MPPT solar controller. I used it every day for the last 6 months. It will run a window 10,000 watt AC unit for 7.5 hours, runs my small wire feed welder. It's purpose is to run a home fridge and 2 chest freezers when we lose the grid again. At 130 pounds and on caster wheels, it stays under the work bench out of the way. What are you trying to run?
Nice build! I was surprised the store bought one looks like it was actually made reasonably well, I was expecting a pitiful battery bank and bad wiring jobs.
I've had decent luck with tacklife products. They're a good chinese brand. I use their jump starter in my car. Never personally used it, but had people ask me to jump their cars multiple times, usually in a parking lot where then you have to awkwardly maneuver your cars to get the leads to reach and whatnot, and that thing has worked every time and holds a charge. Had it for two years now, never charged it once. Supposedly can jump a diesel pick up truck and a Suburban. I have a highlander.
As much as I like the build if you compare it with the ecoflow delta I would say buy is the winner it's more expensive but it has way more features an even bigger ac output power. Overall great build.
I have a couple of small 'power stations' here, inexpensive and LiFePo4 based. Pretty decent. But, as you noted, you have to take their idea of a suitable 'mix' of features, outputs and capacities, and they're rarely in accord with your wants. I also have my house critical systems (except refer/freezer currently) on a battery-backed setup using surplus scooter Li-Ion 36V packs. Now, the surplus quality Li-Ion and lately, LiFePo4 packs out there make a DIY solution way more compelling. You can find all the needed components easily and cheaply to assemble your backup system, or a power station like yours (love the wheels!) with capacity galore, all the inverter and/or DC power you want and the charging options to match. Just several hours to plan, assemble and build. Because there are so many great deals on 36V packs, I was able to find a couple surplus quality UPSes that work great, and under my keyboard right now is a 3000W sine 36V inverter, that'll handle the refer/freezer and microwave loads. And it was easy to use those DC-DC "lab" style power modules to arrange 42V/30A charging. (Using 42V Cisco router P/S as source. Think were 2 for $60? Soo cheap and way quality.) (But see my channel for how not to mount LiPo batteries. Very nasty when poked!) Anyway, if you factor in quality recycled cells out there, (And UPSes! Great quality inverters, low speed chargers and backup. Real cheap Ebay, usually shipped without the failed batteries, so cheaper/safer shipping, and very much life left! I paid about $70 for my 500VA and $90 for my 1000VA shipped. I don't even notice the power drops anymore, except the mini-split stops. Nice.) you can build a beast on a budget! Thanks! Stu (Too much blabbing. Sorry! Love your stuff, and it's great when DIY beats BUY! Stu)
Hay man funny question we are completely off grid out here is South Africa I run our whole house off of a 1kw inverter and have 4 lead acid batteries running parallel at 12v I am charging it from a 500w mppt controller with 4x 300w 24v panales would a bms work of for a bank like that? or would it just be a silly idea. I build our system for about 1500 Euro and installed myself. (Luckley our government is a lot less stringent here )
I'm sure you already thought of this, but for the sake kf discussion: if you do have a laser engraver, you can use it not only to label the ports, but also to mark cut lines on the wood, to follow later with a saw or jigsaw.
sir, are you ok? your voice sounds settled down. and thank you for making this comparison as I always felt commercial versions were under powered and looked cheap. have a nice day!
The best part of DIY is you can choose everything like you can avoid the voltage conver to charge the battery by using a charger with right amount of voltage and you can entirely skip or downgrade or upgrade the inverter like 300w or 1200w.also you can choose what type of battery you need like Li-ion or Li fe po4
If you now ensure that loads can be powered from the wall and the batteries at the same time without interruption (UPS), you'd have a pretty cool multifunctional power supply at hand. No problem if the power goes out because the batteries are topped up and ready to help you get through a few days.
Maybe having a 1000W AC output for camping is quite an overkill, sarcastic if you will. The project looks pretty nice but I'd stick with the buy version, doing some work on the diy version like painting or protecting the wood from rain would be good great video man

for that i use mje"3055" NPN transistor, 22 k resistor and 12 v(1A). power supply.
maybe you should try this or use a zvs circuit, the induction heater you made(for primary coil) for a full sine wave A.C. inverter. You might find it interesting.
Finally DIY is the winner!!
A really cool project. Just saw one of those 4KWh solar mobile charging packs earlier and wondered if one couldnt diy it. When paying 3-4k bucks for one of those there sure might be benefits for DIY. Assuming one doesnt burn the house down with it at least.
I have done a price analysis on building a DIY power wall - and in terms of the price per Kilowatt it is right on par with grid power usage fees! Which begs the question; why aren't more people DIYing their own power security? Great build! The laser labeling is a very nice touch too.
I had the same dilemma, but ended up buying the same portable power station about a year ago. I want to build a larger unit someday. Thanks for the video.
I like how you need an emergency jigsaw while camping, just like how Jason would need an emergency chainsaw while camping, he he. Great one Scott, I love those batteries, must say. I would love to see you build an electric motorcycle someday, one with a sidecar full of batteries.
Always good to see that I'm not the only one who got a snapmaker xD
Very well done, for the full 1kw of continuos power I would have used a set OFC 2 gauge wire, it is still extremely flexible and soft bit would allow for proper transfer. 85 amps continuos through 8 gauge seems a bit weak. That is my opinion however and I build for the extreme as well.
Sunday is completed with GreatScott! ...
I built 2 basically one is 585 watt hour with a 500 watt inverter an the second one I have the battery built with a 1425 watt hour battery and am trying to get a good 1500watt inverter that fits I have tried a couple but they can't do what I need
Watch out. You will get hooked on this stuff. My latest home made power box is 7200 watt hours, 560 amp hours, 3000 watt inverter with 6000 watt 20 secod surge, 75 amp onboard charger, 30 amp MPPT solar controller. I used it every day for the last 6 months. It will run a window 10,000 watt AC unit for 7.5 hours, runs my small wire feed welder. It's purpose is to run a home fridge and 2 chest freezers when we lose the grid again. At 130 pounds and on caster wheels, it stays under the work bench out of the way.
What are you trying to run?
nice gonna come back and watch this later with my food, this is the exact type of video i been needing!
You are perhaps more of an electrician then a woodworker =)
Nice build!
I was surprised the store bought one looks like it was actually made reasonably well, I was expecting a pitiful battery bank and bad wiring jobs.
I've had decent luck with tacklife products. They're a good chinese brand. I use their jump starter in my car. Never personally used it, but had people ask me to jump their cars multiple times, usually in a parking lot where then you have to awkwardly maneuver your cars to get the leads to reach and whatnot, and that thing has worked every time and holds a charge. Had it for two years now, never charged it once. Supposedly can jump a diesel pick up truck and a Suburban. I have a highlander.
As much as I like the build if you compare it with the ecoflow delta I would say buy is the winner it's more expensive but it has way more features an even bigger ac output power. Overall great build.
Portable power stations , great
And I love power stations
They are great
And I love this kind of videos....
You videos are ALWAYS AWSOME !!!
I have a couple of small 'power stations' here, inexpensive and LiFePo4 based. Pretty decent. But, as you noted, you have to take their idea of a suitable 'mix' of features, outputs and capacities, and they're rarely in accord with your wants.
I also have my house critical systems (except refer/freezer currently) on a battery-backed setup using surplus scooter Li-Ion 36V packs. Now, the surplus quality Li-Ion and lately, LiFePo4 packs out there make a DIY solution way more compelling. You can find all the needed components easily and cheaply to assemble your backup system, or a power station like yours (love the wheels!) with capacity galore, all the inverter and/or DC power you want and the charging options to match. Just several hours to plan, assemble and build.
Because there are so many great deals on 36V packs, I was able to find a couple surplus quality UPSes that work great, and under my keyboard right now is a 3000W sine 36V inverter, that'll handle the refer/freezer and microwave loads. And it was easy to use those DC-DC "lab" style power modules to arrange 42V/30A charging. (Using 42V Cisco router P/S as source. Think were 2 for $60? Soo cheap and way quality.) (But see my channel for how not to mount LiPo batteries. Very nasty when poked!) Anyway, if you factor in quality recycled cells out there, (And UPSes! Great quality inverters, low speed chargers and backup. Real cheap Ebay, usually shipped without the failed batteries, so cheaper/safer shipping, and very much life left! I paid about $70 for my 500VA and $90 for my 1000VA shipped. I don't even notice the power drops anymore, except the mini-split stops. Nice.) you can build a beast on a budget! Thanks! Stu (Too much blabbing. Sorry! Love your stuff, and it's great when DIY beats BUY! Stu)
This is my first time see that giant battery 😆, anyway great job.
you are the inspiration for me to be motivated to produce my video ideas. really ! Thank you very much!
I recommend you should get a Impact driver
I expect it smaller than that, but as always, Iove that detail explanation
Yeah, a solar panel would be a great feature!
Great reasons to carry a portátil power supply to the woods jajajajajaja u r great Scott
@GreatScott Are you sure that soldering 220V "mains" is a good idea? (specialy for a "Mobile Device"...)
Hay man funny question we are completely off grid out here is South Africa I run our whole house off of a 1kw inverter and have 4 lead acid batteries running parallel at 12v I am charging it from a 500w mppt controller with 4x 300w 24v panales would a bms work of for a bank like that? or would it just be a silly idea. I build our system for about 1500 Euro and installed myself. (Luckley our government is a lot less stringent here )
Everthing is good but your inhale gives me chills 😬😬
For totally personal reasons i would be really interested in an 12V li-ion motorcycle battery diy or buy
12v? That would require some seriously hefty wiring
Diy or Buy videos are awesome
Great :-)
I'm sure you already thought of this, but for the sake kf discussion: if you do have a laser engraver, you can use it not only to label the ports, but also to mark cut lines on the wood, to follow later with a saw or jigsaw.
I like that the pcb and battery pack have xt-90 (or 60?) connectors attached to it
Long time no see. u look so difference. Stay create & i will see you nexttime
Finally u found a prefect use of ur battery's 😅
sir, are you ok?
your voice sounds settled down.
and thank you for making this comparison as I always felt commercial versions were under powered and looked cheap.
have a nice day!
I prefer DIY powerstation because I can easily fix it or swap defective parts if trouble occur, now I am making 90aH diy powerstation
If you can, buy yourself an impact driver, it makes driving screws into wood a lot easier. Nice job 👍🏼
The best part of DIY is you can choose everything like you can avoid the voltage conver to charge the battery by using a charger with right amount of voltage and you can entirely skip or downgrade or upgrade the inverter like 300w or 1200w.also you can choose what type of battery you need like Li-ion or Li fe po4
If you now ensure that loads can be powered from the wall and the batteries at the same time without interruption (UPS), you'd have a pretty cool multifunctional power supply at hand. No problem if the power goes out because the batteries are topped up and ready to help you get through a few days.
Maybe having a 1000W AC output for camping is quite an overkill, sarcastic if you will.
The project looks pretty nice but I'd stick with the buy version, doing some work on the diy version
like painting or protecting the wood from rain would be good
great video man
I made a 2kwh version of this a few months ago, a $20 plastic tool box is much easier than building own box, and it has a handle
I was just looking for this video and seems like you read my mind . Thanks for making this this video.
Man, I thought your soldering is painful to watch but then you started woodworking...
