Really good video, thanks! You saved me a lot of trouble!
P.S. Nice equipment!
My respect to you bro I'm civil student still i understand everything.. Nice explanation 😋👍
Very informative and helpful, thanks
The voltage differential between the battery and what your trying to to step it down to in QC3 12v mode is too close together or the same. The voltage drop will be due to this most likely. In fact you can damage the module by having the step down voltage differentials too close together. You need at least 1 volt of difference, 1.5v to be safe. You should 100% charge your 12v battery so its at peak voltage or use a 14+ V psu, and do the test again on QC3 12v setting, likely you will have a different result.
nice video thanks for making it.. you have solved my problem sir.....
Thanks bhai 🥰, i like this video a lot🥳
Please try connecting both the modules together to a 80-90 watt laptop power supply ( as tht is the most cheap and portable supply everyone will have). And then test both the USB on fast charging modes with loads on both of them. It will be very uselful as it will tell us that will a 80 watt laptop power supply work with 4 such modules at the same time.
Thanks
How can I set the QC trigger default to 12volt (at power on)?
Thanks for the video
Good Job Man, Thx a lot.
Thank you.
You have very in depth videos. If you work on your channel you can grow a lot. Try getting someone who can help you with videography and editing.
Bhai agar galti se + me - lag jay aur - me + to module kharab ho jayega kya
Sir tell me that can i use 1805 battery in parallel and then use booster module to increase volt up to 12v and then i connect this module to make power bank is there any problem or not
Is there any reverse polarity protection?
Please inform.
This module not available in India so suggest similar and make diy portable mobile charger?
Excellent job. Keep it up.
Have a question. Is it possible to charge a laptop via this module using a solar panel ??. Thanks.
Bhai ise 2.4 amp charger ho skta ha battery btao koi bhe 5 volt ke ya 3 volt ke btao ye isme light konse ha red blue agar blue ho ge full chargers ho ga btao
2 QUESTIONS: Do Buck Converters create "noise" if used with a 12 volt battery to output 5 volts to a portable radio receiver? Is there a way to eliminate the noise? Thanks
Yes most switch mode buck regulators create a lot of noise from the square wave fed to the inductor. It is possible to screen it but most manufacturers don't bother. Better to learn how to achieve this yourself.
This circuit is plugged in reverse DC polarity can not repair. If possible, how to fix it. I was plugged upside down to explode the big two-legged component?
It is not possible to repair.
Hi, have you check the self consumption (I mean, no output) of the module itself? Thanks.
i did not.
@@gurribuy what a pitty
I have some of these QC3.0 modules,, I planned to use them in a battery bank, but they do not seem to fast charge my Samsung devices. the units do not kick up the voltage, my Samsung device will only slow charge, it says to use original charger.. Are these not Fast Adaptive Charging compatible ?
what type of battery are you using, how many volts does the battery produce? also what samsung phone do you have?
I wanna usethis in a power bank but my cells out put voltage isn't that much as they are 18650 cells so what should I do, use a step up converter
There are powerbank modules available in the market you can use them. And yes we need to step up the voltage which can be done with a powerbank module.
Very good idea.
you do understand how QC3 works?
Hi, could you clarify if it is input 6-12 v as stated in the description, or 6-32 Volts as at 37-38 seconds. Thanks
yes, it will work with 6-24v. but for fast charging the input needs to be at least 12v.
If i put 24v power supply also no problem right?
@@fazry88 yes, no problem with 24v.
But how hot does it get when it decides to go into full current mode? Does the chip melt off first or the inductor? Can it be cooled?
It does need not need cooing if you don't draw more than 1A
Please review any other modules available for purchase.
Can you include usb meter while charging redmi7 @12:40, so that we see what is the current, voltage, and watt required by that mobile
Can fast charging or suport vooc?
i have this module with DC jack input. is it ok to direct it to solar with 20 volts? or does it need to connect to scc or mppt?
No, you an directly connect this to a solar panel.
In fact most foldable solar phone chargers use these modules directly connected to the solar panel.
Aap Jo battery liye kaise charge karety battery or battery charger Ka link de
Worthy video
Please do a full charge test with solar pannel
Very good video, in 1st test why not put voltmeter across battery, 2nd test using solar PV, put voltmeter at input terminal and why not plugin USB meter rather than lying on your table.
in 1st test, i only had one pair of alligator clips, so i could not attach the voltmeter. In the second test, you are correct i should have shown the voltage of the solar panel and should have used the usb meter to show its output. Actually, that was the plan but, i forgot.
Helpful ...
Can it support one plus 6 dash charging.. i.e. 5v at 4A !! Is it possible to fast charge a OnePlus device with this module
This module can output 5v at 3.4A. But it will only give 2A to your one plus device because it does not have the dash charging chip. So, it will charge your phone but only at 5v 2A.
Can use this in solar tracking system using Arduino Uno board ?? It works ?? Reply bro plzzz
I use whit 6v solar panel and tp4056 to charge 18650 cell...👍
Good vdo basically...
Good video
thank you.
Thanks for the video man, i just bought this thing, but it only gives me 4.8V - 1.2A at load, do you think it safe to charge my phone with 4.8V?
yes, you can charge your phone with 4.8V without any problem.
@@gurribuy great, thanks man
Most of the voltage drop actually comes from those cheap usb meters...
how to trick my powerbank to output 12 volts 1.5 amps ?
using the zendure supertank (max output 20 volts 5 amps)
looking for a quick charge board that tricks powerbank?
powerbank outputs 5volts by default
you need to buy a " PD decoy trigger" they are available in 9v 12v 15v & 20v fixed settings and in some module you can also switch among the voltages you want. just search for pd decoy or pd trigger on your preferred site.
@@gurribuy thankyou, will order one asap
Dose the usb module support usb type C trigger board.
NO.
2 good bro
Great 👍
It says 6v-12v input, can you try with 6v battery
Do you mean with this +12V we can charge fast charging Phone and also if its a normal Phone ?
yes, IF you give this module at least 12v and at least 2 amp. Then you can charge any phone whether your phone support fast charging or not.
Where did you get that yellow voltmeter
banggood. china.
Bhai direct phone charge kar sakte hain kya isase . Input 4.2 output phone charging Kar sakte hai kya .
Phone kharab nahi hoga na
Mujhe pawer bank me lagana hai pawer bank ka kit kharab ho Gaya hai .. Kya sahi rhega ye
Plz Bhai reply kro plz
Basically basically
Mujy ye chayie pakistan me ye kaha miliga
it claims that it can output 12v. Will it step up the voltage to 12v if my input is 6v?
its not a step up module its a step down module. To get 12v the input must be higher then 12v.
@@gurribuy ooohh ok thanks!
Смое понятное видео, пока что, из всех что есть на RUclips)
cool, but how can fast charging battery it self ?
IF you are talking about the 12v battery i used. then unfortunately you will have to charge it separately using a battery charger.
@@gurribuy Q: can we charge Legacy Lion batteries using Qc2 or Qc3 ?
Is it safe for Android devices? and the voltage when to charge the mobile phone stays at 5v?
yes, this is safe. voltage will stay at 5v if your phone does not support Qualcomm fast charging. But, if you phone support Qualcomm fast charging then the voltage will change according to your phone.
@@gurribuy Meaning, the module can automatically adjust itself?
Wow you have all usb gadjets..... I want all!👍.... Price kya he sab ki pls reply...
I made it work the first day. The second one the module light flash and was not able to charge the smartphone. Dont know what happended
Only you know what you did. However connecting the plus and minus wire with wrong polarity can also damage the module.
Make sure that your polarity is correct and you are not supplying higher voltage than is supported by the module.
@@gurribuy Dear Gurriby, thanks a lot for your prompt answer. I am using a little solar panel which provides almost 12v but obviously not fixed as depends on weather. The module output is giving me 5.1v on the usb but only worked yesterday. Today module is going on off every 2 seconds and as a consecuence smartphone do not charge. Thanks again
can it charge normal phone some phone doesn''t support quick charge feature
yes. it can charge any phone with or without fast charging.
@@gurribuy thank you..can 8.4 volt give quick charge? I would like to supply low power in order to prevent ic inductor from heating.
wo kya cheez hai bhai volt aur ampere dikhaa ra hai , usse kya kehte hai
usb meter.
can i use a 12v 20A battery to power this up?
yes, any 12V 20A battery will work. Just make sure the polarity is correct when you are connecting the battery to the module.
@@gurribuy yes bro
You should at least supply 15v or above for it to work properly
Why? It is a buck converter, so anything from 8v upwards should work just fine. It only requires 2-3v headroom above 5v. More than that will not "improve" it's ability. His 12v battery is almost flat (should be around 14v).....that is the only reason it can't supply enough amperage.
What is
The input current and max output current I need what input current is needed
ITs specification said that max output power can be 24W.
And the input range is 6v - 32v.
This info is enough to figure out what input current to might need.
@@gurribuy in a test video it showed it cam go upto 3.4 amps and after adding Inefficiency the stuff is output current is 2 amp max so should I supply with 2,3,4 amp and plz tell me how to figure out the input current
@@Abhyuday_rai what do you want to run with this module?
@@gurribuy mobile and other usb accessories
@@Abhyuday_rai you can use 12V and 2A or more amp as input.
what is the max current input for that module sir? thanks in advance..
Depends on what is you input voltage.
@@gurribuy lets say sir 12v 12amp is it ok to put 12amp or its already high..?
@@NEWBI3GAM1NG yes, 12amp or even higher will work. The module will only take what it needs.
@@gurribuy thank you very much sir..
How to cut between two modules safely?
you can put the pcb on a table edge so that only one module is hanging outside the table edge.
then just bend the module down it should snap clean.
if you are not sure then scratch the seam between the two modules with a blade and then break them appart.
@@gurribuy thank u ,it works
Can we use 6v solar as input And charge the note 7 ??
yes, you can but remember that this module is a step down charger so, it will convert 6v into 5v and charge your phone. But, it will not trigger fast charging because for fast charging you need at least 9volts. IT is better to use a 12v panel if you want the fast charging as well.
Also, if your 6v panel outputs very small current your phone will take much longer to charge.
@@gurribuy actually I have the 7.5V solar.... It will be helpful at only emergency time or not ?? If I don't have need of fast charging
@@kumar2646 It will charge but only in full sunlight and charging will be very slow.
@@gurribuy OK thank you so much..... I will use 2 solar panels.... Thank you
Can we use with solar
yes.
@@gurribuy can I get speed like you shown in video
I have battery of 4000mah like a lipo battery and a mobile battery will it work with this module proper ly?? I want to charge my redmi note 7 from power bank, Reply asap pls
For this module to work you need voltage higher than 6v. Lipo battery has a voltage of 3.2 to 3.7v so you can't use this module with a single battery however if you have more than one battery then you can use this module.
@@gurribuy first of all thanks for replying, I did tried to connect to battery which combines and make a 7.5v but my phone charges for 3 to 4% and stops automatically, even after battery has juice left again I have to put back on to charge and same thing repeats, I am using a basic power bank module which has a output of 3.7v any suggestions sir?? What should I do to make a good power bank at home that actually works.
@@tanveersayyed8855 what module are you using?
@@gurribuy I am not sure about what module it is I removed it from a cheap power bank a basic module with one female usb and charging point beneath it
@@tanveersayyed8855 try using a single batter and see if it works, IF it works then instead of connecting the battery n series connect them in parallel.
Apakah itu otomatis berhenti charge di saat baterai smartphone penuh? From indonesia
bantu jawab bro, setau aku kalo gasalah yg ngatur state baterai ngecas dan berenti itu dari hapenya, bukan darii modulnya. modul ini cuma bantu stepdown ke voltase yg dibutuhin sama hp nya gituu. cmiiw
Can u please post the link to buy from amazon
its sold out, from the seller i bought it. Now, it is available at a very high price. If you still want it then just search 'Qc module' on amazon and you should find it.
U can buy it from aliexpress for much cheaper price and those sellers are much better than amazon! If u dont recive the item u can get a full refund ..
Plz give link to purchase ds
just search ' Qc 3.0 module ' online and you will find many website selling the same.
can I use it with 3.7 v li ion cell
yes, it will work but the voltage needs to be more than 5volts. So you will need to connect at least 2 lithium cell in series for it to work.
@@gurribuy I have 14 cell in parallel....what to do now
@@woodway8300 you need to make few sets of 3 cells in series, then connect these sets in parallel. this should give you about 11v, then you can use this charging module.
can we use for car ..
yes.
bro this is work with 3.7 volts
This converts higher voltages into 5v, 9v and 12 volts.
This can't convert lower voltages to higher voltages that mean it can't be used with 3.7 volts.
I know you want to use this module like a powerbank but you can't. Hope it helps.
It heats a lot over 1.5A
At what volts are you drawing 1.5A. I will check with my unit as well.
Where we will get this module
i will tell you the link after lockdown because online sites are not listing all the products at the moment.
@@gurribuy ok
Online buying link please

when i bought i paid about 600 rupees for 2 pcs but now the price has increased.
Mrp
But it's useless for me its don't have inlet battery charging features so I can replace my power bank pcb kit
its not for powrbank, powerbank circuit uses a boost converter to boost battery voltage to 5v. This module is a buck converter it reduces higher voltage that is 12v to 5v .
At same price you can buy isolated, circuit protection & complete assemble gadget car mobile charger
@@AmirAnsari-mp7id car mobile charger don't work with voltages less than 12v.
@Gurribuy what are you doing on video with 12 v battery anyway what are you doing with this module at least charge a phone other than nothing one module of price is 419 you have bought 2 so 419+419= 838 you just charge at a time two phones and need a battery that will drain extra on your pocket Qualcomm quick charge 3.0 power bank price at least 999 you can charge two phone at a same time and no need to paid extra for battery
@@AmirAnsari-mp7id Take what you can from this video. And do what you think is better for you. i have tested the module but its upto the viewers what they want to do with their money.

Quit shaking your hand during the close-ups, it's making me nauseous!
I'll keep that in mind next time.
Sorry mate but is the pub manufacturer paying you for shilling them? You say that it works "perfectly fine at 9 volts " but after 1A, the voltage sags and at 2A it is below 7.5V. At 12V it fails horribly, clearly this is shit design, how can you say it works perfectly fine?
It is below 7.5V, how can it be close to 8V when it is closer to 7?
My battery was really bad, I also tested it with computer power supply 12v rail.
it easily outputs of 2.5 A at 8.8 volts if you use a good battery or a capable input power supply.
may i have your email please , i have some queries
