I've seen the resistor data on the chip data sheets, but I've never seen anyone actually change one. Good job! It must take a steady hand for that soldering work.
Great work ! Thank ! for years looking for an answer in Russian UA-cam to this question! You are a real man!
IAM actually searching such useful video.
Well done, keep it up, thank you for sharing it with us :)
I think it's more crucial if you measured the V between the battery terminals rather than at the incoming port of the charging circuit/power adapter. I'd opt for the charger which will give a 4-4.2v over the battery terminals. I'm not too sure but I had the impression that most li ion batteries last longer with a nominal 500mA charging current. Anyhow, batteries are dirt cheap nowadays.
Usually manufacturer gives you info about charging current for example 1C to 1.5C or even more for high current cells. So for low capacity cell 500mA is ok but for higher even 2A is ok.
I want to increase the output current of usb port on battery bank, right now it is 5v 1amp, there is also a barrel output of 8.4v 1.5a, 8 charging barrel port of battery bank is 12v. So i guess it is easily capable of 5v with 2or 3amp output. If it also as easy as just to replace resistance, i will love to know. I have 3 of these banks lying around, but to slow for current devices
Very nice Sir. What charger did you used in the first testing. because the output volatge is 5,25 volts. very nice. Thank you
Very nicely done videotutorial.
guys be careful
this method worked for me but in the excitement, I reversed the polarity of the battery in the final assembly which causes the failure of IC
now this module only charge the battery but doesn't give output
great video bro, I have a cheap power bank like your my ic model is mp3401A I only see PGND NOT Prog like your can I put the resistor on the PGND ?
I want to ask if the port usbnya hot like fire if they can be repaired
Power brake GIC market Mein available hai
which is you used current measure meter? where is you buy?
How can you change the output voltage? I want to insert one of those in a wah pedal but it needs 9v
You'd need a voltage step up (you can probably buy one for cheap on aliexpress or something) but consider that you'll lose amperage according to V=RI also I'm not entirely sure how the whole circuit would take about having to provide the required amperage, honestly you're better off buying the proper charger
What does charging chip ? Is it a ic ? Anyway, which works on the ampere to do less or high output providing ? Capacitor ?diode? Resistance?
Charging IC is configured typically by external resistor. Wach again my video :)
Thank you.
спасибо мужик! =D
Я прям думал, напишет ли кто - нибудь из наших )) Тоже долго искал ? )))
why doesnt the manufacturer put that resistor.doent seem like it would cost a lot to put that resistor.is it because it gets too hot?
Watch video carefully. There is resistor but I changed its value to provide more charge current.
cbm80amiga yeah.but why don't the manufacturer put the same resistor as you did.sorry for my english
I have no idea :) Probably they just wanted to charge Li-Ion cell longer.
does this effects the output
Awesome video! Did this also increase output current of power bank itself? The original output current is about 500ma only.
No, this resistor is for charging only.
Thank you.
My Ambrane power bank get full charge in only3 hours & geting discharge in half an hour. 10400 MHZ. I checked all cells are giving approx 4 voltage. Can you help me, What to do?
Probably one cell is broken, desolder them all and measure capacity.
Im not familiar with this module. what about overcharge protection
Everything is described in the datasheet :)
My auto charger output is 500mah . so is it possible to increase output into 1 to 2A here ?
Usually yes. You have to identify charging chip and find its datasheet in the internet to find out more details what to change in the circuit.
I think that I burn it. I didn't put the battery correctly. How can fix that?!
I think you permanently damaged it.
If I use 9 Li-po battery in parallel I mean 3.5V and 9000 mA Can this circuit carry that amount of current while charging or discharging????
+Sashanka Kumar Pramanik No, only max. 1A.
charging a single 18650 at 500mah is better than charging at 1A.. charging at 500mah the battery will hold a charge better and the battery itself will last longer. charging at 1A will speed charging but it puts strain on the battery
+Mix Bag Time is more valuable than old 8-year 18650 cells. This was the purpose of above hack.
What's the device to measure the usb current and voltage?
usb doctor or usb tester
I have noticed that these modules when used to charge something like a phone have a difficult time maintaining or even reaching 5 volt output. Mine is usually at 4.95. I think they would do a better job of charging if they were closer to 5.1 volts. Is there a way to increase the output? I don't have a schematic to look at.
Are sure that it is really fault of power bank module? Usually voltage drops are generated by poor quality cables. I haven't notice any voltage issues in my case. But even 4.95V is quite ok because phone charging unit decreases it to 4.2-4.3V depending on lithium battery used.
It is a power bank module. It charges the internal battery and puts out current to charge a cell phone. They are kinda cheap and I think lacking quality, as the one I mentioned doesn't power up anymore. The heat from charging must have damaged it.As far as the cord I have used many. I also have a battery bank with 4 cells that works just fine and does put out 5.24 volts when charging.
Bro this module only convert upto 3.6 volt to 5v would you hack this and make it convert 0.9 v to 5v
Step up chip doesn't support such conversion. But there are special modules which upconvert
@@cbm80amiga thanks for your reply
i see u suggest to soldering 6th pin, but in pratice u solder 7th pin. which one is true? or the datasheet and the real has a different pin position?
It is 6th pin - the chip on the video is upside down, look at the dot at the chip - this is 1st leg.
i have a olight 3400mah battery protected, but for some reason it's giving me 1 full charge on my galaxy s2 which has a 1850mah. when I plugged it into charge the battery, the red light seems to be always on. over 5hrs now. Do you know why I can't get more charge from that battery?
ccfilms The reason is obvious - this is fake capacity.
ccfilms not only is your battery prob not 3400mah, its only 4.2 volts fully charged and it gets boosted to 5v to charge your device so you will lose some capacity ie if your battery was twice the capacity of your device you might get 1.25 to 1.5 charges of your device.
ccfilms Also take into account that capacity in lab is measured by discharging to 2.5-2.7V, but most power bank's step-up converters cut off the output at 3.0-3.1V, so actual used capacity is smaller.
how many voltage charger use for 2200 mah battery
Voltage is same for all capacities. First stage is CC then CV as usual for Lithium cells.
awesome
Nice !!!! Can You help me please ??? I have a XDL-M2 v3 board. Please !!! I put 3 Samsung 3400mha batteries and it take too Long to charge. More than 12 hours
I even don't know this board. Try to look for datasheet for main charging IC on the PCB and look for possibility of setting charging current in similar way like in my case. But I doubt it will be easily possible.
I didn't find the datasheet :( but that power bank case Is really common on ebay
That's the problem with Chinese ICs, there is no information or markings are removed. I'd suggest to try other case but it is always lottery what you get.
why is factory ouput so low? can 1A destroy battery? and how much amp my battery need?
+Ji run 18650 cells can be charged with 0.5-0.7C so 1A is ok for typical cells.
for AA or AAA recharged lithium bateries?
No, 18650 - so called laptop batteries
so I can charge 18650 b with 1 amp, its faster, but better is 0.5-0.7
If your cell is 2600mAh you can charge safely up to 1.8A.
But this power bank case supports only 1A max.
Is there a way of changing the output current to 2.1Amps?....My phone takes forever to charge
No in this power bank case. But there are cases for 2 or more cells and they provide 2A.
Thanks
hey

Chineese!
Right :)
Ross Evans... And they run the Show Baby. Dream on .!
Wrong. Electricity takes the least resistive
Path. If you have 2 resistors in parallel of different values. The lower value will be used and the higher will be ignored completely
+RGHxFTW This is something very revolutionary you are writing here :)
omg :D

That's 100% true :)
😂😂😂
I think you need to reconsider your whole life my friend..
does this effects the output
Output current is still max 1A. It seems to be boost converter chip limitation.
