This is a nice little project, especially when the weather can knock out your entire power supply like it did here in 2011 from an F-5 tornado that knocked down transmission lines & we were without power for almost 7 days, so this would have really come in handy for at least to have some lighting. Thanks for the idea.
"And finally we have two little modules that are optional, this would add safety [...]"
"optional"
lol
5:00 what they teach us in callege xD
@Christian Bridger Dude if you're gonna promote your dumb app, at least don't use 2 accounts made the exact day of your promo

That's brilliant man. There is nothing on the market like this, and it's nice to know how to make one.
Nice project but the wires connected to the outlet seem pretty thin
Nahh. It's gauge 14, just has a thin insulator.
The current flowing at the output is pretty low. The input is what you should be concerned about. But 14 gouge is enough anyways.
They could actually have been smaller
Current at the output is not the concern, it's the thin wires and high current on the input.
Thin wires can melt easily under high current, true.
That's a GREAT project! Really nice! I only have two doubts: first, how do you know it's fully charged if it doesn't have an LED or something to indicate? Second, how much amps does the BMS support and how many the inverter draws?
THANKS! Um, you'll know it's fully charged when it stops consuming current. The 3-cell charger acts as a standard lithium charger an a high & low battery voltage cut-off protection. I figured it might complicate the project to some people so I made it as primitive as possible. If you want to know if it's full, you might want to buy a digital Ammeter module! :)
TechBuilder Yeah... That's not a bad idea. But... Well, my doubt is because I personally have this problem, there's a lot of projects that I would love to make and need a battery pack like that. You know? But to put an ammeter in every project (even a vacuum cleaner, for example) would be a really good solution. :/
Hey, i'm a complete noob but I really want to do this project. How can I tell If it stops consuming current? Can I just use a multimeter or is there a different way to do it. Thanks!
picubed_13579 I really would like to know too. :/ Maybe if you find a 12,6v charger with LED state... But I have no idea of where you could find it. :/
In my opinion simplier option would be buy quad copter battery (3s) and a balanced charger for your battery and that would be it. And power bank batteries are not rated for those loads (120w/12v=10A, and these batteries load tops should be 1A, quadcopters batteries are rated for higher loads eg 40A).
Thanks for the video, and can i use 3p 3s Lithium ion(18650) batteries with output voltage as 11.1v and capacity is 7800mah for the same project?
Great vid. What can you use to indicate how much charge is left in the battery?
I would recommend using a thicker gauge wire for the terminals to the output port as well as a circuit breaker for safety. Another note, maybe a larger power bank could be made using recycled 18650 cells.
was going to say the same thing. when in doubt BIGGER WIRE lol
its a low ampere so its fine
@@dailypinoytech6132 it's
300w /12 = 25.... it was 300w right?
If it was 150w then 12.5amp.
I'd say 2.5mm cable (with a fuse)...
why convert to AC first? if you want to charge up your laptop you could gain a lot of efficiency if you dropped the powerbrick and AC altogether. just use a constant voltage controller and set it to 24 V or whatever the laptop powerbrick used to output.
my thoughts exactly. so many devices work on DC nowadays! i think versatile battery banks should be more common than USB-only or AC-only ones!!!
it would be better, but just for sake of simplicity its easier to do it this way, its good to power something like 120-240v LEDs, or charge phone, with only around 80Wh you wont get much of a charge for laptop (since you are gonna lose alot due to inefficiency)
well its not for just laptop...maybe you need to power your blinder at the beach or fan?
Check out GreatScott's channel, he recently made a great power bank for laptops.
@@TechBuild much better, safer and prepared than this. Scotf has a phd while this guy has master in failures.
I miss these videos sooo much!!! Great work!
Very impressive portable power inverter. Nice build and design.
Thanks!

Isn't it BIT overkill when you transform some voltage (about 8V or how much) to 230V AC and then back to about 20V DC for laptop?
OMG he has uploaded something again! Amazing!
Okay this sounded sarcastic but im realy glad you are back again
Thanks!
By the way I always liked your videography methods and I like your style now too! You play a hyperlaps of all the steps while you explain what the step is, pretty cool
Hey man great job! I see a lot of people hating (probably my fellow electrical engineers). The concept is great and regardless of how good or poorly the project comes out there will always be haters! Just refer back to a wire gauge chart + amperage calculator to put those haters to rest. keep up the good work.
Ah finally, had been waiting a long time for you to release some project Angelo.
Thanks Yash!
TechBuilder man you have my same name
Well done, love your projects
@techbuilder wow I like you and how you do your videos. Very clear. I'm going to build one of these but using 18650 batteries. Likely a few dozen of them or as Many as I can find. I noticed the balance charging module is 3S so would that still work for me?
You've got an awesome channel here, my guy. Keep up the great work.
How do you know if the batteries is charged ?
I love the video very much and will try to do it soon hope it will work
Awesome video and awesome project. SolidWorks! A wonderful tool. very impressed. I have been thinking about doing a project involving a 12v 20Ah Sealed Lead Acid battery and 200W invertor. It will weight a bit more than yours. Li-ion have a much better Power to Weight ratio than Sealed Lead Acid Batteries.
Thank you for sharing such a simple guide to build a powerbank you are truly wonderful and generous ^^
Build? I need a cheap way to put my plug into my powerbank, i forgot to bring the 3ds to usb charger cable so i need an otg for the ac charger, I'm literally otg so no access to a wall and it's hard wired from ac to 3ds
really useful. my 220v Powerbank just gives me additional 6 Kilometers range with my Xiami E-scooter when i charge while driving. Thats priceless!
hey is it essential to have 3 batteries? because i have one 25,000 mah battery, so would that work? this is a great video thank you so much!
If ever i use 12v/24v car converter can i connect an extension wire so that i can use many accessories?
Me and my classmates is planning to do this project but we will add solar panels, what we gonna do?,
My question is is it ok to use old phone batteries with 3.7/3.8volts instead of power bank?
Awesome work.
Anet A6 .. is it a good buy?
Pls give suggestions on the 3D printer and share the link to buy one.
Any idea on what is the power output limit for your project? Will it be able to charge gaming laptops?
Most BMS can handle up to 20v DC input so if you're charging your powerbox using a laptop charger that has around 17-19v then you wouldnt need a step down dc module, right?
how much amps can handle the step up converter ? I think it will be around 4-5 amps so bnasically at full load you´ll able to take out around 60 watts, before the circuit blows.
Awesome video dude, great contect and quality. It must get bloody hot in that little box when the inverter is running however with zero airflow :D
Question can you charge it and discharge it at the same time, what we're seeing is can we hook it to the solar while charging my cell phone at the exact same time
I always thought I could be an inventor but I guess not, I respectfully envy this kid.
hey ! they teach us solidworks in France too ! :D
tho , i might lack patience , material or skill to do it myself (also i don't live in city so it's harder to find everything)
is there a way to buy one already made ?
I love this guy, he's so smart for his age. Like a real life Data from Goonies LOL I want one of these but there is no way I'd be able to make it, not even if I watched a million TH-cam tutorials :D
Nice one. My old Dell M6600 charger has the following specs:240W AC Adapter, 19.5V and 12.3A. Would this power my laptop?
Nice project man. I will also try this. I have one suggestion for you. Try to arrange a system to balance charge your battery pack to make it more long lasting. Otherwise everything is okay.
Looks very nice. Although seeking a simplier and much quicker way would be my route...leaving out the 3D printer and ordering lithium batteries from Amazon. But a great video with some great ideas.👍
I have always wanted to do this for my laptop because the battery dies so fast and finding wall sockets in university classrooms is a nightmare. I gave up on using extension cables because it is awkward and difficult to find a plug sometimes the plugs don't work. This way I will always be connected to power and it would be handy for a phone as well. My only concern is: Is the device a fire hazard? If the batteries blow up surely the wood would burn? Also it would be really cool to find out how to add a battery regulator - some sort of display maybe next to the switch that would show me how much battery is left in the battery charger.
will you please tell which kind of box you used to store your screws because I want to buy some
Gotta admit you're a beast and I wouldn't even be able to do this watching the video. Even though you did a great explanation
Brother if we installed 4 or more batteries then also we have to use 3 pcs 1N4007 diodes or per battery per diode...
how can you know the charged level? and how many hours/minutes at its full 150W could hold?
How long do the bank last? Because to step up a lower voltage to a higher voltage, you use amps. I can't imagine that with that sort of amp pull that it would last very long, but it is certainly still an awesome idea!
hey awesome build! its really helpful! Btw, where did you bought the 3D printer? im also from the Philippines
Will this work with a 30:1 scale gaming laptop
*WHAT'S A FULL SIZED LAPTOP ?*
is the regulator necessary since you have installed a BMS?
Hey i just got the inverter from you link, it has a problem, cut off at 11V or 3.67V/per cell which is still kinda high for lipo, so much of the energy stored in the lipo not being utilized, and hence reduce the working hour of this powerbank. I'm going Li-ion which can go as low as 9V or 3.0V per cell
Where can I find the two little modules.The 12v stabilizer and the other that connect to the Lithium ion
Cool. But how long can it last? For example, how long will a tv stay on? How many charges of a laptop? Just an average, I know it will vary depending on the item powered, but just want to make sure if it's just a fun project, or a real world functional device. Because that way I won't be wasting the money, because it has lots of parts to buy.
we're currently doing a similar project like this on our thesis and your questions are our exact research problems! we're going to test it on different small appliances and devices =)
Nice project. But have to mention, dont use DC-DC step down converter which dont have Current limiting option for charging any type of battery. there are lot cheap modules capable of doing CC.
also use some balance circuit for lipos, not only protection board you have.
You are 100% right.
I used a dc to dc converter with led display. I did not use the one diodes because of that but it is working so far but the diodes are are a good idea. I am going to use one from an old computer power supply
naka Series po yung battery pack? 8000mAh lng sya? gano po katagal bago naempty?
are cdrking power inverter good im planning to make one using my drill batteries???
Hey i was just wondering wether it is safe to use thin wire like you did, because when you ran the wires from the inverter to the power socket, you replaced the thicker wire wit very thin wire. Is this safe ( this is around 7:05)
6:26 could you also solder more wires to the original ones attached to the inverter to extend them? I'd probably forget where the + and - pins are if I desoldered the whole thing.
Is it safe to plug something that needs only 64v - 74v into a 220v outlet ?
Finally a video!
AWESOME
Can i run inject printer 🖨 at outdoor, if it is then how many time to use? And have any ac output from this device? If it's not work then suggest me how kind of think I need to use as light weight device?
hey my concern is how you monitor/prevent the lipo from being overdischarged?
Hi, did You measure an output signal wave? Is it a sinus wave or square wave? What is the output power of the system?
BTW great work. I like it!
greetings!
Hey man I would like to build a battery pack for a shop vacuum and maybe a electric pressure washer. Here in California my buddy's and I want to detail and be more green. Can you help us?
So I know charging off of a battery can destroy ur battery in ur phone will this destroy ur battery? Because it's AC and the charging brick can provide the same voltage and other electrical things to the phone, right?
How long it takes to fully charge using solar? Last question is how long can be lasting the battery to run a 15w light and small fish tank motor pump? Thank you for your help dude...
I have a question, I plan to do the same but with the power bank I want to convert 5V to 12V with a dc dc step up and then use the inverter so 12V to 230V and my question would be how much amperes would end up
what the diodes are doing in pack and how you will give voltage to led indicator
are you using lenovo legion y520? mine has some hinge issue, does your laptop has the same issue?
Instead of 3 batteries can you make a 5 batteries with a capacity of 20000mAh each? Thanks for the reply
This is nice bro 👍 I loke it working on a build currently thinking bout useing 18 1.2 volt 5000 mah D tenergy batterys something i had laying around the shop
Also, need a Fuse in the DC side to prevent over discharge current from the battery. I assume the inverter is protected against over current on AC.
I did! I did some circuit analysis on the Lithium Balancer Module, it's equipped with those.
Did the box heat up after prolongated use ? Even if the inverter is around 90 % efficient it would produce at least 10 to 15 watt of heat. I don't think all that heat in a closed box full of lithium cells is safe.
But I think the worse is the the section of wires on the DC side and the BMS only rated for 5 amps.
This is a great looking project, I hope your version 2 will be near perfection.
Does the output of the charge circuit module output 12v? Or will it go down as the batteries go down?
Thank you for the inspiration I wish you prosperity in life
What are the numbers of the zener diodes on the lithium ion Bats?I saw some diodes there,What are there connections?.i know it's another safety feature
Bro I’ve been waiting for a new vid for the longest time
this screams "fire hazard" does it have safety circuitry to prevent the battery voltage from dropping too low?
how can u charge the battery through the panel with a dc jack connector?
This powerbank have serial connection of the battery (8000 mah together)?
i saw ur comm at the song "i follow rivers" thats how i found u
can we create just like that by using sediments?
Would be nice if you gave a link for the power banks you got the batteries from
That’s a neat design, where did you learn all this from?
what diodes did you use in the circuit and why? as you didnt mention them at all
Will it work if I plug a device that only requires 12v into it?
Please how long will it work before it runs out of power
Question: What is the diode for and is it necessary?
Is it pure sine wave inverter? It's better to use pure sine wave specially electronic devices.
Hi its a really nice project but isnt it a waste of power to step up 12 volts to 120-220 only to step it down to 20 volts with an laptop adapter?
Can I charge my 180w laptop with this ?
Thanks
can you run 220 watt ac adapter by which ac outlet ?
Is it advisable to use 3 batteries, or its okay to use 1 ?
Damn, I was expecting an adult. Good Job!
So if I wanted to make a DC wall outlet powerbank I just leave out the inverter?
Bro, finally you are back. But why u didn't upload any video in few months? I love your all projects and I had made my first DIY project after seeing your project. Thank you so much, bro :)
I have a question. Can i use this as a science project for school (di po ba sya plagiarism kapag ginaya ko) icecredits kopo sa inyo yung project
I respect you because you can talk fluently on camera. how do you do it ? :-)
HaHaHa...For a 10-year-old it's gotta be tough. Maybe school would help?
simply . he is Asian
Mohammed Mahagna I am asian to
But he says m-a-h instead of milli amp hours, kinda drives me nuts
me too
aslo why is a cell balancer optional
Its been so long!
This is awesome
Thanks!
Very cool, this is a fun and useful idea. How long can you use your laptop on? I have a half dozen lipo batteries for a quad copter I no longer use. It might be fun to try this with those. Any idea what I’d do with the balancing cables?
One serious point and one nit pick though. You said you chose wood to sit atop your inverter because it was a good insulator. The case of your inverter looks like passive heat dissipation (it was aluminum with ridges). Isn’t that to let heat escape from the inverter? You wouldn’t want to put an insulator on top of that-it’s like misting yourself because you’re hot, then putting a jacket on over it. You can buy aluminum project boxes that have the ridges on it’s exterior, that would help draw the heat away from the jumble of components.
And then the nit-pick. You don’t use contact cement like you would regular glue. It’s called “contact” cement because it’s glues on contact. It’s like making a sticker. You apply a thin coat to surface of both items you want to glue together, let it dry completely (usually it shouldn’t even be sticky to the touch), and only then do you press to two dried patches of glue together (that’s the “contact” part). It’s often used for big sheets of things that would be difficult to clamp or hold down. Using wood glue to apply a veneer to a full sheet of plywood would be hard to clamp, and it would take a long time to dry to dry because the glue in the middle is several feet from any air source. Contact cement dries quick because it’s fully exposed, and then you need no, or minimal clamping because it sticks instantly when you apply it.
I think you should make a portable Bluetooth speaker you will get a lot of views and we all know that you love speakers. From your instructables. A small one I mean not the big one like your previous build
I shall! Thanks man!
Did you think about heat dissipation?
What is the power output of this "powerbank"? 110 - 127v or 220 - 240v?
