My Power Bank Rivals Commercial Ones?! Super Fast! (DIY or Buy)

nice video but i have a few question as an IT guy who want to DIY my powerbank:
- why most people use li-on battery like 18650 instead of li-po like 1260110?
- can this go with 1260110 battery as i having 2 cell here but as i see your battery output need to be 22.2V so ... each battery is 3.7V then i need like 6 of them?

Молоток !!!

Can I charge this 4S battery pack with my old 5V 2A power adapter? & does it automatically communicate with the load device for Power Delivery voltage settings?

I always like your videos. What is the input of the board.

Would this board support 3.2 lifepo4 cells? It seems it starts from 3.6

whats the solder spot on the side for?

Can anyone tell me how to activate this module. I thought that mine was broken so I bought another one. I can charge battery with it but I can't charge any device connected. I have charged 3S2P battery pack from zero to full, diodes were lit correctly from 1 to 4. But after that it just doesn't turn on when I connect my phone, camera or PD tester.

is it possible to add two such modules to a single battery bank and achieve a path through capability like an UPS ?

There are these 12V ones for a wifi router they make use of 3 li-ion cells in series. This one has more cells.

its funny how no one separates the series groups lmao. microns of plastic preventing a dead short.

Hello 🙂
Thank you for this video. This could be a solution to build a powerbank out of tool batteries like makita, bosch etc?
This would be a very super project - are you interested to figure this out?

Have an issue with my 100W PD​ board.
I changed the resistor (to a 27K) for 6S 2P (21700 cells) but it only charges to 21V (5S). Anyone have any ideas? Something g else I need to change?
The pack is about 8.5Ah

You did not share link for the cell

I have scoured the internet and can't seem to find a pd that automatically applies voltage per device from 5v-20v. They are all manual. How are these power bank companies making these devices that automatically switch between voltages? or do they make them in house?

Do you have a DIY UPS for 12v electronics such as routers? or a recommendation which PCBs to look at?

Can i change this usb c to usb a port??

It would be interesting to build a small 5V USB UPS that uses pass-through, to charge the battery only when necessary while powering the output from the input in normal circumstances.
There are no small devices like this that have pass-through, only "classic" powerbanks but too big for simple UPS requirements (clocks, Raspberry, etc.).

What size battery?

what subject is this, i would like to learn

5 volt çıkışlı power bankların çıkış voltajı 7 volt yapabilir miyiz powerbank modülüne birkaç değişiklik yaparak

I like your all videos, Please make a video to combine two of these 140w modules in one powerbank because one port is not enough.

I'm wondering if the IP2368 has pins, from which I can get the battery voltage directly, and still have all the features like capacity management, low voltage shut down etc... Which I don't have when I directly solder something onto the battery directly, if I understand correctly..

Isn't it odd that it can't deliver the advertised current, even though it is very efficient, and isn't even getting hot? Probably a 2 cent component in there somewhere that was almost as good as a 3 cent spec part, but can't quite go rail to rail...

i bought my baseus blade 100w for 45 euros condition new , in a local wholesale store , when i asked in retail stores was over 100 euros . and baseus wasn't the expensive one because i bought another power bank for 25 euros ''earldom et-pd31'' it's 60000mah but does not output or input a lot of watts , max 12v 1.5a 18 w so i need it baseus blade 100w or the smaller one 65w i think it was , but i went with the 100w for my laptop

What BMS is used? Can you add a second (third, fourth) PCB to have 2(3, 4)*100W Output?

I like your video I get an idea now Thank you. Now I plan to create my power bank too. Can you create a 33 watts power bank 10V and 3.33A with a input and output? for my reference for creating a power bank too. Thank you.

Too bad you dont sell these as kits!! Id buy one or 2!!!!

I had a quick question about the RBAT_NUM . As per the datasheet, the minmum cell is 2? Any help would be really appreciated, thanks in advance.

I recently soldered a mobile Powerbank charging module to a 35mah battery.
When I charge it, the led of the charging module lights up , but even after charging it for 30 minutes it doesn't charge my phone .

Does anyone know how to solve this issue?

I bought same module i think I'll make a 100w Power Bank for my phone and which is also supported supervooc 100w but when i completed with the power bank i see my phone only charge at 10w but when i use with my laptop which supports 65w so this properly delivered 50w and charge my laptop.

can I get the 3d design u made its look amazing and simple

The voltage drop seen is likely from the li-ion cells not being capable of of the load each cell would have been subjected to.

I'll go with the buy version.

Great, informative video! Love the no nonsense engineering speak and brought to light some of the terms that are also used with the IP5389 board that contains the battery balancing and over charging, battery protection all on one board, along with a thermistor. The problem is that I cannot get to push more than 3A (60W) even though it is rated for 100W. However, I am currently using a Dewalt battery clone as my LiION source which I have used with a UPS board from MiniBox with GREAT success, but the board is expensive and frankly not very efficient requiring fan cooling. It is also 3X as large as this the IP5389. Both have columb cirucuits, but was hoping to have at least an I2C bus to gain access to the bus to add a USB port to bring the data over to Windows, sadly this is not the case and biggest advantage with the ‘Open UPS’ board. Maybe using your technique and forehead slapping moment & “why didn’t I think of that” was taking an image of the PDF on the screen to translate the data-sheet, geesh forehead is sore now. But at least I can make more progress. Thanks!!!

I envy the knowledge you have. Do you have any videos explaining the basics of these type of electronic devices?

you can buy a diy kit from Ali for around $30 then ust add batteries

beuatiful video good job

as shown in video , i think it does not support pps protocol which used in samsung smart phone for super fast charging.

I'm embarking on making this using 64x 18650 using 16x 4x 18650 cell holders with a 4s BMS and hoping it works

Thanks for the video, please I have some questions do I need to set the output charge to a particular voltage or it automatically select according to the voltage of what I am to charge, and what is the voltage of the adapter to recharge the powerbank thanks so much appreciate u.

Hey Scott, I tried using this module with a 4s lithium Ion pack, but even after charging it up (cells were already charged and it blinked the 4th/4 led) when i went to try charging a device, it blinks rapidly and doesnt charge anything!

any tips?

How much battery capacity should i use for module? Is 5Ah enough or should i go with 10Ah higher? Im planning to use 4s battery config

Is there a way to limit charge power? I want to build a powerbank for tool batteries. 12v 2 to 6ah. Thanks!

Thanks for the video , since there is very little info in the internet about issues i thought asking here. the module indeed output 100W but it does not charge the battery (although the led is blinking) the battery is at 14.9v (50%)
second issue - it does not charge my Samsung phone , it gets into a loop of connect-disconnect mode. any experience with that ?

Wheres the links for the two pcbs in the build? You have only shown the small one not the two big ones. Thanks

💖🙏
