So how to build a $5 Power bank? Requirements $20 Laptop Battery $3 Wires & Cutters $10 Multimeter $5 Soldering Guns $2 Battery charging Port $1 Led Light & Now We can Build $5 Powerbank using Equipments of $41. 😂😂😂😂😂
I do have 4 laptop batteries on me, I just charge all of them and keep swapping when I'm travelling or something... You might get some for free just by visiting a nearby electronics recycling center, check eBay as well they won't be expensive
aliwalyd3 lol it's very arrogant to think people don't need to be instructed on safety. Every one who has ever begun a new study started as a "fucking idiot."
Agreed but I don't believe the danger referenced is about body contact with the iron. I think it has to do specifically with soldering ON batteries. Could be wrong though. OP is kind of vague for using "near."
Late answer I know but why do you think this is unsafe? It's literally the same way normal powerbanks are made it just looks a little bit better because a machine made it and not a human
It's only a matter of time before the soldering comes off . You need to use a thin flat metal with welding to connect batteries. Look how the batteries are connected in the laptop. It's because of the current draw pre cell , Irrespective of the voltage. ( All are in parallel)
Not from really old batteries, but when a fairly new battery dies overnight it's almost always because of the failure of a single cell. So while 3350 mAh may be out of the question, don't be surprised to find cells still containing in the 2500-2800 mAh range even if the battery as such is completely dead.
Håkan Rohdin most batteries from laptop are close to 2Ah, you might be lucky and find 3Ah, ive got almost 10 old laptop batteries to experiment with and most of them were around 2Ah and got about 1.5Ah of usable capacity (also alot of them were dead)
Soldering skill and the box is the best I ever seen. Also as a note, Li ion batts need balancing and monitoring circuit but nt this crap. If you want your power bank to last few uses it's okay. First time I see electronics in such a safe case.
If you ever make a 40,000MAh. And use a cheap Li-ion charger, it will take ages to charge the battery pack up. Cheap Li-ion charging boards only supply 1- 2amps charging current at the most. Which is practically very slow to charge a pack of 40,000mah.
And then, you only get around 30 Ah out of it, since the cells would have an average 4v (3.7v-4.2v) but the usb uses 5v to charge, also take losses in the circuit in account. That's about 10.000 mAh less than advertised
Nice video is there any risk like explosion or fire to the site powerbank with normal usage And how to detect that the battery is fully charged or not And what if it is over charged ?????????
anish kamble a portable solar cell is too weak to charge 18650. If i don’t mistake, great scott or linus tech tips did a video testing different powerbanks, some with solar panel
The video maker is being disingenious, he basically just paid for the charger board since he used old laptop batteries for the cells itself (The most expensive part) .
I think you should have also included overcharge protection. That is very important for your phone and even power bank. It doesn't even cost much. Ask me how even a fuse could have saved my monitor.
Awesome video guys . You should make content like this more often.😊 And also where I can find the laptop battery cell in market as I don't have a laptop . And what are they called technically ?
THANK YOU FOR PROVIDING SUCH AN INFORMATIVE VIDEO!! HOPE YOU GUYS REACH 1M SUBS. I AM THINKING OF BUYING A SAMSUNG GALAXY NOTE 8 IS IT WORTH THE MONEY OR ANY OTHER RECOMMENDATION.THANK YOU VERY MUCH BEEBOM!!!!
Neat stuff, however I need to mention having all cells connected like that means some will charge faster then others and have a very good chance of over-charging, might get quite toasty around that battery pack when they do.
That's pretty awesome. I made a housing that you could add/remove 4 batteries from it for charging so that some could charge while I used it. It was then as simple as connecting the leads to a broken USB car charger I found. Funny thing is, I found everything I needed for the project for free, from the cells down to the chargers for the batteries. Two vapes someone threw away because the tank broke, but the mechanical parts were perfectly fine besides an almost unnoticeable imperfection on the led display of one. Another nice thing to note is that 2 batteries alone can power a raspberry pi 3 running retropi making the perfect battery pack for my portable arcade.
Great work BeeBom.......!! It's like what we say in India..... Kabaad se Jugaad......!! & the result here is awesome!! We would definitely like to see more such DIY videos from you guys.....!!
Hi can you tell me how is the best way to charge your macbook? shall I use charge all the time i am using it or just plug in every often? everybody say different. Please let me know.
Good that you have started DIY videos. Such instructional videos have long term value compared to unboxing and reviews. Any chance of cardboard covers catching fire given the fact that batteries tend to heat up while charging?
Is more volts like 4.2v means more battery life or fast charging or slow discharging or anything like that..??? What is the difference between 3.7v and 4.2v Does it matter in performance??? Reply plzzzzzzzz
Awesome video.. as u said it's always feels good to do something by ourself.. but since we are dealing with batteries (especially older) it's too dangerous.. there is lot of chances of blasting.. please check for the safety... Or suggest safety for viewers..
woaah no no no no bro. do not use AA batteries. they dont have enough capacity. even 10 of those wont be able to full charge your phone. stick to lithium based cells. the boost converter wont work 1.5 volts
The charging speed is pretty impressive. However, I was wondering what additions I can make into the setup to get a higher charging speed? I have a Turbo Charger at my disposal. Are there any pieces I can use by dismantling it?
1. Cheap charging kits typically has 4056 like charger IC that can supply maximum 700mA continuous charging current. To fully charge your 40Ah power bank at 90% efficiency, you will need more than 63 hours! I doubt through it can supply 40Ah. 2. Many 18650's have built in thermal fuse that blows up making it completely unusable if you try to solder it's terminals by hand. 3. If you really have the itch of making your own power bank, you can purchase batteries, enclosure & PCB from the market & assemble it on your own rather than trying to reinvent the wheel.
He said a lot wrong stuff. This Guy teaches how you salwidge them Probaly: ruclips.net/video/MPiLKDNLM9A/видео.html You have to test the capacity and all cells must have the same voltage. This Charger is only for four or five batteries and it will take over a week to charge it with the rated capacity. You will never get 3000mah batterys from laptop batteries or 2000mah or 1500mah
For the size of powerbank , 6 to 8 h with normal charger isn't enough to pump up all cells. Typical charging time @2A would still be 20h. Considering efficiency of dc-dc converter at 80% max in ideal cases for cheap coverters, it will take more than a whole day to charge this thing. Also batteries do discharge as time goes. So yeah do it if you're doing it for fun, otherwise get readymade as it has better overvolt and undervolt protection which cheap ones usually doesnt include, plus which are specially made for set of Li-Ion cells. Its maximizes battery life as well.
Congratulations, you made a high-performance bomb.
Then how do we solder the batteries ?
🤣🤣🤣🤣🤣🤣
So how to build a $5 Power bank?
Requirements
$20 Laptop Battery
$3 Wires & Cutters
$10 Multimeter
$5 Soldering Guns
$2 Battery charging Port
$1 Led Light
& Now We can Build $5 Powerbank using Equipments of $41.

As an electronics teacher , i think you should also mention precations while soldering near the battery...
Also not insulating the wires and that horrible soldering job.
aliwalyd3 lol it's very arrogant to think people don't need to be instructed on safety. Every one who has ever begun a new study started as a "fucking idiot."
We both are. However, you can't go around assuming that everyone is intelligent enough to understand basic safety.
Agreed but I don't believe the danger referenced is about body contact with the iron. I think it has to do specifically with soldering ON batteries. Could be wrong though. OP is kind of vague for using "near."
As an English teacher , you should use spell check!
This is very unsafe...
Not saying why is very remiss...
Why?
May explode if any error while making

Are there any heating issue?
How about throwing in a solar cell with these batteries.
anish kamble a portable solar cell is too weak to charge 18650. If i don’t mistake, great scott or linus tech tips did a video testing different powerbanks, some with solar panel
We want more budget FRIENDLY tricks regarding gadgets i.e DIY vedios..!!! This VEDIO was VERY MUCH AWESOME.. DUDEZ!!!!!
Wouldn't 18650s with different Ah rating used together in parallel be dangerous? The cells would not charge and discharge at the same rate.
the voltage stays the same for all batteries, it just uses more Amps from the batteries with more Ah (as far as i know)
Rodney Yrureta could be, but looks like he's bottom. Balanced them
if you'r using lithium POLYMER(some old batteries) battery,yes. But no so much for lithium ION
That's only the case when they're connected in series
None in this video is safe. The Indian guy is really unsafe.
whoever decided to market emojis should be shoved into a box and launched into space.
It's not 5$ battery.

go for s8 plus instead (if u r not into dual camera)... cause note 8 is too big for daily use
samsung galaxy note 8 ...its definetly worth it cuz im using it ......you will definetly get what you pay for
Wait for iPhone X
wait for s9 if not in a hurry
Wait for one plus 5t if you don't care about the brands
Will it be able to maintain constant current and Potential ?

In what way
How its seems helpful to you
hey beebom ...i want to ask u
is that safe..??? if overcharge can get 🔥 t???
phone battery can get damaged?? , please give. solution on that
Always waiting for your video...#LoveBeebom
Is this setup is used in power banks in the market...?? And how we'll be sure that it won't cause any damage to our mobiles...??
So 12 batteries ? Each one of around 3,3A/h ?! Keep on dreaming :D

Can I use double A batteries Instead of laptops
Aamir Asad if they are rechargable then yes
You can buy a powerbank instead of rechargeable AA batteries.
No you can't! As AAs are rated at 1.5V as opposed to 3.7~4.2 of lithium.
very good question bt ur questin gave me a heart attack
dude actually those double AA batts are 1.5 v compared to the recommended 3.7-4.2 v batteries
woaah no no no no bro. do not use AA batteries. they dont have enough capacity. even 10 of those wont be able to full charge your phone. stick to lithium based cells. the boost converter wont work 1.5 volts
The charging speed is pretty impressive. However, I was wondering what additions I can make into the setup to get a higher charging speed? I have a Turbo Charger at my disposal. Are there any pieces I can use by dismantling it?
Only thing could be making it in series to rise the voltage

2. Many 18650's have built in thermal fuse that blows up making it completely unusable if you try to solder it's terminals by hand.
3. If you really have the itch of making your own power bank, you can purchase batteries, enclosure & PCB from the market & assemble it on your own rather than trying to reinvent the wheel.
