Finally, someone comes around and shows HOW a decent power bank is made DIY. You made a superior product, so in my opinion, it doesn't matter if it's just a little bulkier.
There is no way someone can make a better video on how to make a powerbank. I really like that you pointed out the difficulties someone may encounter with such a project. let's all hope that the other channels out there will do the same in the future.
this is the excellent diy powerbank I have ever seen in youtube. This is very eazy to build and your video is perfect to build the powerbank. Hatsoff to your idea and design.
A really well made video. I liked A LOT the fact that you used fuses on each 2 cells group instead of just connecting them straight in parallel. This is the kind of DIY videos I like. Keep up the good work!
Excelent execution on the explaination, I've understood it much better and much deeper, now i can move on to my future power generator projects that is completely pended for a very long time,my big problem is batteries, because they have limitations,excelent job man and thank you
Good explanation and easy to understand language at a moderate pace. Very useful video. Thank you Sorin. One of the best video tutorial with near to exact and real values. Best of luck on your journey of spreading knowledge.
I made this power bank! Confirmed working and a great way to create a DIY USB 2.0 Power bank. I think I need to get a better boost converter but it otherwise charges my phone and works as a powerbank.
hi. I suggest you use this step up converter: goo.gl/8HEsQ2 it's much stable, when the cells get low on power, than the one I've used in the video. and don't forget the 12 pins switch.
i must say brother u r one of the world most organised and standard and clear human..... and for me honestly u r one them from today "MY PERSONAL UNKNOW FAVOURITR's' .........tq
Sir Sorin your videos were very interesting and creative. Thank you for making these videos. I hope you make a video on how to salvage a lcd of a defective laptop. I would like to see your version of it coz the other videos arent that good like yours. Thanks in advance.
Now, this is what i'm talkin about. I'm about want to make by my own using tutorial in YT, but non of them tell if the PowerBank itself have protection....And lastly, i found this, GG
5:04 I'm curious in your schematic why you connected the negative wire from the output of the charging module to to negative output of the Step Up Voltage converter. I thought it should be connected to the negative input of the step up module.
Sir Sorin your videos were very interesting and creative. Thank you for making these videos. I hope you make a video on how to salvage a lcd of a defective laptop. I would like to see your version of it coz the other videos arent that good like yours. Thanks in advance. Kudos to you!!
Fain de tot. Mă bucur că am dat peste canalul tău. Chiar acum o jumătate de oră am demontat o baterie veche de laptop și mai am vreo 3-4 prin casă. Am să scot modulele din toate și-am să le verific să văd care mai sunt bune.
hi. it depends on the type of battery, ni-cd, li-ion, lead-acid, lifepo4... if you can give it enough current, yes you can use it to charge a battery, but in combination with a charging module for that type of battery. for a li-ion battery pack for ex, you can use it to set the needed voltage and power a BMS that charges that battery pack.
Why do you charge them in groups of 3? You can parallel the 3 TP5060 for 3A charging. What will happen if you do it like this, is that, which you also mentions in the video, is that the TP5060 modules are slightly different in end charge voltage, so you battery pairs will be at different voltages, somewhere between 4.21V and 4.11V, so when you flip the switch and switch your batteries in paralel, some current will run between the batteries, possibly not enough to blow the fuses, but you are wasting power and adding resistors as your solution is also wasting power. Just parallel all 6 cells and all 3 chargers and you'll be fine.
hi. each tp4056 charging module has better control over the charging process, if it charges only 2 cells in parallel. every electronic component has an acceptable error, usually of 1%. so if you connect all 6 cells and 3 charging modules in parallel, the charging modules will not read the exactly same voltage, and the charging current will be slightly different. so they cannot be coordinated to charge exactly the same way. the cells voltage may fluctuate because of this, while charging, this is not good for the cells. in my configuration, each pair of cells is charged as fast as possible (depending on the 5V USB charger) without any interference between them. and when you fully charge them, all the cells will have the same voltage ~4.2V. there will probably be a difference of only a few mV between them. the power wasted through the resistors is insignificant. the power wasted from the self discharge rate of these old salvaged cells will be higher, than the power wasted to keep the cells from getting unbalanced with the help of the resistors.
In stores most of the power banks use large single cell type LiPo batteries or something similar like a huge phone battery. Basically it's just big and flat. I like the idea of adding in your own cells when the old ones wear out. Which you can do if you have a soldering iron, you need a pretty powerful soldering iron to solder things to the battery terminals though, as they suck the heat away fast into the battery and that heat can easily warp plates and damage the internal battery. So you need a soldiering iron tip that is incredibly hot so you can do the job fast. You probably need a soldering iron tip of like 400 degrees Celsius at least to do this. I wish they just made a cool empty battery bank that you could add say 8-16 cells to. And you don't have to solder them in, instead being held in tightly with high quality springs. And it would have USB output and 12v output, as well as input charge via USB or AC adaptor charging for faster charging. This would be really cool, because people could easily turn a bunch of laptop batteries very easily into a useful battery in their home. I mean just 16 average laptop cells combined will give you at least a 35000 mAh battery. Maybe they make something like this already, I haven't looked. But I would rather something with useful functions and easy to put together and replace batteries, instead of something I have to solder together while worrying about damaging the cells and needing an expensive high temperature soldering iron etc and then having a pain to replace them.
you can use a 3pdt switch with 2 tp4056 modules and 6 cells. you connect the cells in 2 groups of 3 parallel cells. each group will be connected to one tp4056 module.
I made one using 3 parallel 4 series 4 cell 18650 battery,. I have a dedicated BMS to balance my battery,. And as an output uses a 5 pcs 6-24v to 5v 3A step down buck converter. I used 16.8v input to charge my battery. Usually it would take 2-3 hrs of charging. And can charge 5 devices simultaneously. And it's bulky, pretty heavy and would last more than 10 charges if I'm the only one using it. Pretty good for camping.
hi. I've used it a few times, it can charge my phone (with a 3000mAh battery) 3 times. it works great. the step up converter gets a bit hot, but there is no problem. that's why I added the heat sink. and it's getting charged up very fast, even with a 2A phone charger, because it's using all available current, not just 0.8A - 1A, like the rest of the powerbanks.
hi. you can't connect the battery terminals of tp4056 modules in parallel. there will be a small voltage difference between them, the voltage does not stabilize, so the charging process will not go well. the charging modules may get damaged.
You could have bought a power bank module, they are available online and have all the balance charge, over discharge, overcurrent and boost features, as well as the built in meter.
I thought about this too but I don't see any that can charge the batteries fast enough, most of them maximum charge current is 1A which is okay if you have 1-2 batteries. Unless you have a link to one that can charge up to 2A because I am trying to build one that has 6 18650s in parallel. Been looking but no luck.
hi. these are the dimensions 125x80x32 mm. I have it from a local store, but I think you can find a similar plastic case online. for a USB C output I did not found a converter so far.
This diy power bank is very good, with some updates can get better, I'll do one, for sure (if I can get money because the situation of Brazil is a bit difficult here).
This is a nice build. Thank you for your efforts to share with us. Would there be any problem taking this unit on a plane, because it is DIY? For lowering the profile of a toggle switch, another option is to trim down its lever. If the lever is metal, a hacksaw may be needed for cutting and a file for easing the edges. Remember to seal the entire device with painter's (blue) tape, before starting to cut, to keep the metal shavings out of the switch. I would also like to see a DIY battery bank project that uses a DIY battery management circuit. I just have a problem trusting the cheap Ebay modules. And, learning about the circuit and building it is way more fun, IMO, even if it costs a little more.
hi. I don't think they will let you take it on a plane, because it's DIY, it's pretty big and it has a lot of lithium cells. probably if you build a smaller version it will be ok.
Impressive video! I wished if I watched it before making my bulky 6s 18650 pack. I wonder where did you get that soldering gun? I like the fact it can solder directly at a battery in mere seconds.
Hey there .....your project seems very good and I just thought of making it......but when I made it the negative supply is not available at output module(step up module xl6009)......I didn't understand how xl6009 will receive negative supply.... without negative how it operates and give 5v dc.....kindly suggest my mistake.........🙂
hi. first of all you need the MT3608 step up converter, it's better than xl6009 at low voltages. the IN- and OUT- are bridged on the board. the negatives IN and OUTs are common on all modules, so it doesn't matters where you connect the negative wire, it's the same on the input and on the output of the module.
Hii bro i made this power bank but i have one issue.. When the cells indictor on 40% battery the xl6009 step module only give 10 to 90ma not giving 1amp please help me..
the xl6009 needs a minimum input voltage of 3V. when the battery discharges below 3.1V, the step up converter will not work correctly. that's why I linked a MT3608 boost converter in the video description: s.click.aliexpress.com/e/_9wol94 it works with a minimum input voltage of 2V.
Nice project! The most informative and safety that i found. One question though. How did you protect the 18650 from the modules from each other? In case 1 of them over heats
hi. I used sticky foam tape as spacer between the charging modules and the cells. the charging modules should not overheat, only if they are damaged. if there is too much current, the fuses will protect the cells.
I've built two of these now using salvaged laptop batteries. Thanks for the instructions. One question: when I charge my phone with these it only draws about 0.5A. In the video it looks like you easily get upwards of 1.5A when charging your phone. Any idea why I am not getting that? My phone draws 1.2A from the wall socket.
Good thing! Do you have ideas how to make something like this, but with bigger amount of batteries? More batteries- more capacity, but complex construction...
The XL6009 is a dangerous module, that, should the input fall below 4v, you can have erroneous voltages of between 20-30v frying your precious devices, as it doesn't have under voltage protection (this can happen on switch on/off also).
hi. when I've build and tested the powerbank, there were no problems with the step up converter, as you can see in the video, even at low voltage. but later after I've used it a few times, it started to make problems sometimes, when the battery voltage got below 3V, the output voltage was not stable. so I've changed the step up converter with the one in the link below. I will make another powerbank video soon with higher capacity and more features and I will explain this modification. www.aliexpress.com/item/32450571426.html?spm=a2g0s.9042311.0.0.27424c4dYDNnaS
@@Sorin_DIY Yup, the MT3608 is what I have used, as per your guide, but it itself does have problems, mostly due to the lack of proper information in how to set up the module. Quite a few of these units have been 'smoked' right off the bat, as it's not clear as to how one sets these up properly, and the data sheet provides no easy way to do so, for the newbie :) However, if I may Sorin?, direct you to an easy explanation as to why, and how, to go about doing so, and it's just because I stumbled upon it myself, but it may help others from smoking these modules, as they are rather better than the XL6009's :) th-cam.com/video/yD7fMylYgXw/w-d-xo.html Feel free to delete the link buddy, but I just learned the proper way of setting up this module myself (from this), so hope it will be of great help to you and all involved in this great project. Keep up the great work my friend! :)
Great video! Very informative. But one question, what are the specification of wire that you use. Im a fan of what you are doing and i'm also new in this.
Why the resistors connecting the + of the batteries? And also I don't know, why he use XL6009 DC DC Converter? It cannot be from TP4056 module direct to Charging USB?
UPDATE: Instead of XL6009 I suggest you use the MT3608 boost converter, it's much stable when the cells get low on power.
Xl6009 latest model instead of MT3608 how is possible?
i have a question , how many cells i can solder to one module ? tp4056

That old baby at 10:58; tell him(?) I love him(?).
4:42 This is not correct because USB can only transfer 2.5 amps. You must have 3 USB ports, which must be powered at the same time.
you could also just use a different connector to supply those 5V...
think ATX PSU 5V Rail for example

the xl6009 needs a minimum input voltage of 3V. when the battery discharges below 3.1V, the step up converter will not work correctly. that's why I linked a MT3608 boost converter in the video description: s.click.aliexpress.com/e/_9wol94
it works with a minimum input voltage of 2V.
Extremely talented
Nice project! The most informative and safety that i found.
One question though. How did you protect the 18650 from the modules from each other? In case 1 of them over heats
hi. I used sticky foam tape as spacer between the charging modules and the cells. the charging modules should not overheat, only if they are damaged. if there is too much current, the fuses will protect the cells.
I've built two of these now using salvaged laptop batteries. Thanks for the instructions. One question: when I charge my phone with these it only draws about 0.5A. In the video it looks like you easily get upwards of 1.5A when charging your phone. Any idea why I am not getting that? My phone draws 1.2A from the wall socket.
Hi. Did you bridged the 2 data pins on the USB port?
@@Sorin_DIYI had not done this. Now I did it and I am getting 1A at 5.23V. Thanks! By the way, I like the switch but is it really necessary?
Good thing! Do you have ideas how to make something like this, but with bigger amount of batteries? More batteries- more capacity, but complex construction...
I will make a more powerful UPS soon with a bigger LiFePO4 battery pack and more features, that can be adjusted for different loads.
The XL6009 is a dangerous module, that, should the input fall below 4v, you can have erroneous voltages of between 20-30v frying your precious devices, as it doesn't have under voltage protection (this can happen on switch on/off also).
hi. when I've build and tested the powerbank, there were no problems with the step up converter, as you can see in the video, even at low voltage. but later after I've used it a few times, it started to make problems sometimes, when the battery voltage got below 3V, the output voltage was not stable. so I've changed the step up converter with the one in the link below. I will make another powerbank video soon with higher capacity and more features and I will explain this modification.

@@Sorin_DIY Yup, the MT3608 is what I have used, as per your guide, but it itself does have problems, mostly due to the lack of proper information in how to set up the module. Quite a few of these units have been 'smoked' right off the bat, as it's not clear as to how one sets these up properly, and the data sheet provides no easy way to do so, for the newbie :) However, if I may Sorin?, direct you to an easy explanation as to why, and how, to go about doing so, and it's just because I stumbled upon it myself, but it may help others from smoking these modules, as they are rather better than the XL6009's :)

Feel free to delete the link buddy, but I just learned the proper way of setting up this module myself (from this), so hope it will be of great help to you and all involved in this great project. Keep up the great work my friend! :)
Great video! Very informative.
But one question, what are the specification of wire that you use.
Im a fan of what you are doing and i'm also new in this.
hi. I used wires from an old PC power supply. I think they are 1mm wires.
@@Sorin_DIY
Thank you very much sir! ;)
Why the resistors connecting the + of the batteries? And also I don't know, why he use XL6009 DC DC Converter? It cannot be from TP4056 module direct to Charging USB?
