I think this 2A meant to be the current which can draw maximum at any conversion. So for an example 12 to 24 conversion if you set the input current to 2A, 12Vx2A=24W and the output will be 24W/24A - (loss of the conversion) = less than 1A. So I hope it works as they specified.

[@BingoBongoMan]

"...24W/24A..." I guess you meant 24W/24V (Volt not Amp)! Other than this I think the same. Test failed by 12 to 24 with 1.5A but got kind of better with 1A and passed with 0.5A, so if you calculate the inefficiency or as you say loss of conversion something between 0.5A and 1A should be in the advertised 2A max. in this case.

Seller explained and I followed his instructions and it worked, if you've spun it the wrong way 20 times it can 50 or 60 turns the other way to get it right, once you hit the sweet spot they work great. Seller does mix up counter clockwise and clockwise in the image but good product.

[@yuliankalchev4030]

Just calculated for module 2Amp maximum for input ( actually is too much) and depends how many times increase voltage with same times divide current on output from 2Amp. But keep in spare Calculate 1.7A in inlet. If want from 5V to make 10V 2 times output current 1A . If want from 5V to make 20V 4times output current -0,4-0,45A Better find other modull :)

Now I understand that this module can only handle 1A of current, not even 2A. Or maybe yes, if the output voltage is very low at 3.3V and 2V input, bcs low voltage means higher current. Once the voltage higher, the current limit probably getting lower.

did it already.added 82k resistor to 22k trimpot.this is for the version where the 3 rd leg of the precision trimpot IS connected and the voltage variation only occurs over about 20k. in the second variation the 3rd led of precision trimpot is not connected to anything and voltage variation occurs more evenly over a 100k normal trimpot

[@esecallum]

remove the 100k trim pot and replace with a resistor of 39k and 50 k variable resistor with a knob.you will get a range of 10 volts to 22 volts.or 39k and 82k to get 10 volts to 27volts. or 39 k and 90 k to get 10 volts to 30 volts.

Nice video! I appreciate how you showed that the chip got hot with high load as well as when using a large input/output voltage difference. The MT3608 is quite a powerful little chip, but one needs to understand the limitations of these modules. I killed one myself when making a 9V rechargeable Li-ion battery and then fixed the module by replacing the chip. On my channel you can find the videos I made about that.

I have given input to this module from Li-ion battery chaging module to get 12V output. When battery voltage drops around 2.8v or lower, the out put is not maintaining 12v. It's reduce time to time. I mean, if I connected 12v LED strip to the output then, blinking happens. Can you pls advice ?

[@stevenbliss989]

It is 2A switching curreent, NOT output current. So (over simplified) if voltage doubles the current halves AND less with switching loss so 12 -> 24V likely 900mA max.

[@thra5herxb12s]

I have used this same converter to step up the battery output of my 6 volt motorcycle, so I can use a 12 volt led rear light, because I have more choice of bulbs in 12 volts.

[@robojax]

I have sow how much current this can handle. so for your bulb, either check the current rating (ampere) or if you know the power for example 12W. then I=P÷V, I is current, I=12÷12=1A. make sure the current of the bulb is not higher than this module. Please replay here if you used it and it worked. Good luck

[@ringwood]

I had purchased five of these circuits. Hoping to convert 12 volts to 18 volts. With no load, I connected the input to a 12 volt battery observing correct polarity. Each one immediately snapped and smoked and did not function. Is there something I am not aware of about connecting these to a 12 volt battery?

[@robojax]

This is what happend to me with other boost converter. Apparently for all boost converter, we should have some kind of load otherwise the voltage continuously increase and it burns when the voltage reaches above the limit.

[@ansk]

I've ordered this module and is yet to be delivered. Thank you for reporting. I guess the trimpot is the culprit here. It might be at its lowest output setting.. maybe for 5v or even 0v... and you were connecting it to 12v source. The input voltage has to be lesser than the output voltage for a DC boost module.. Can't be vice versa! Next time, try turning the trimpot screw anti-clockwise as much as you can before connecting to the battery. To be extra safe, try connecting it to a 3v coin battery (maybe CR2032) and read the output voltage before connecting it to a powerful battery. I'm fairly sure a coin battery doesn't have enough juice to kill this module.

[@ringwood]

@@ansk thank you for that information. I had purchased some more of these and this time attach them to a variable power supply starting at zero. I slowly increase the voltage monitoring the output with a slight load. I was able to adjust the output and raise the input voltage to the 12 volts I wanted to use.

[@ansk]

Thanks for the reply. :) Took your advice and used a DC voltmeter (about 20mAH load) instead of a multimeter to read output voltage. Source were 2xAA used batteries with total voltage of 2.7v. The maximum output voltage I could get was only 26.9v! Maybe my module needs 3v min input for the rated 28v max output?! Anyways! My requirement is to power a 12v 10w (833mAH) LED from 2xAA NiMH 1.2v 2600mAH batteries. I hope the module does not heat up much.

I don't remember the minimum voltage this module needs so watch it. if it is within equal or greater than minimum input voltage of the module, then yes. Keep in mind that the total power is that matters. for example if you have 2V and 12A P=2x12=24W so you input 2 watts. and this module can't add anything into power or watt. you may get 12V and 2 because 2x12=24W. this is ideal. converts have 10 to 15% losses. keep that in mind.

Thank you in advance

[@robojax]

What you are looking for is called amplifier. This is regulator and keeps the output fixed regardless of input voltage. Amplifier will have some gain factor for example x3 or x100 or x2.5 and whatever the input is, it will multiply it by the fact as longs as it is within the limit of the device.

[@MrStarbit]

Robojax Is there an amplifier you would recommend. I basically need it so expression pedal that puts out 0-5v but I need it to put out 0-9or10v

[@MrStarbit]

Robojax not sure if I'm completely wrong but could I just use a standard 10w 8ohm speaker amplifier or would I need something more specific to accept the 5v coming in?

[@robojax]

Speaker amplifier is not suitable as the input and output are non linear, meaning the output doesn't follow the input in a straight line. it is more curved and you will not get desired result. How ever it is possible to convert or make one of these modules to your application using arduino. But you would try different module and find the right one. Using Arduino you will read the pedal voltage, and correctly send signal to the potentiometer point of the voltage regulator and will act as if you rotate the potentiometer and the output voltage is changed.

Hmm. If input is 7.4V, is that chip able to provide 1.5A@12V?

[@robojax]

it will for sure output 12V because it is boost converter. It is all about power P=IxV where I is current in Ampere. Output power can NEVER be greater than input. We will always have 5% to 20% losses.

[@redmidubai3005]

Does this converter work backwards or if applied 27 volts on output will it generate 3 v on input?

[@robojax]

No it doesn't. That type of converter is called Step Down or Buck converter. This is just boost converter.

[@codaemon375]

What output do you get with a Vin of close to 0 Volts?

[@robojax]

I believe I tested it with the minimum voltage. I did not got to close to zero.

[@Lann91]

Can't power my 12V 1.05A fan with it properly. From 5V source. When i increase the current limit, around 1.58A it starts to show voltage limit, then current limit on the bench psu, and the fan spins down a little, then back up again, and then down, it repeats. Measured the output, it was around 7.6V instead of 12V.

[@robojax]

Your total output power can be more than the input power. Is the input power enough?

[@Lann91]

@@robojax I mean, if i set the psu to not limit the current, and set the voltage to 5V on it, shouldn't the boost converter just draw enought current to power a 12V fan that i'm using with? Or i'm totally getting this wrong.

[@robojax]

It should get 12v and the output current is what I have tested it as I don’t remember. Yes it should

[@Lann91]

@@robojax It is working with a lower current fan (0.3A), but i needed the bigger one, for a fume extractor project. Guess i will need to find another solution, to drive that 1.05A fan, gonna get some laptop psu or something. Anyways, thanks for the help and reply, and thank you for your videos.

[@leoncryp8182]

Thanks for review, and very detail testing, Im planning a project, Power an Amplifier from 2x USB ports, will this work ??? Amp = TPA3110 type, with 2x 10watt 4ohm Speakers. Trying to power this thing from 2x laptop USB ports with this boost converter (5v to 12V), already tested my usb ports, both ports can handle 5V @ 1.5A = 7.5W each = 15W for both USB ports (possibility more if i change to better shorter cables) Planing to connect the 2X USB ports in parallel into the boost converter? If i get minimum 15W output that should be enough to power my amp/speaker in medium volume.

[@robojax]

I have read this 3 to 10 times and every time I come across it under "no answered" comments. Just calculate the power for your amplifier. For this module you can get the power form my video.

[@ObiDanKinobi]

Hey dude. I've just been tatting about on a similar project. You can power a 10w (sound level) battery powered amplifier (Kustom KGBAT10) via a 2.1mm Jacked 5v to 12v step-up transformer. Works well. Bear in mind sound wattage is different to power wattage. I'm gonna stick a multimeter in the circuit to measure current and see what the load in real-terms is. I used an Imuto 20a/h powerbank.

[@chergaoui.en2roues]

Is there any converter that can convert from a battery that have 3.7V; 2amps and 10000mAh to 19v 4Amps in order to charge a laptop ? ?

[@robojax]

voltage is V, Current is I and power is P. So P=IV and you have a battery 3.7(2)=7.4W and get 10(19)=190W. it is like you have $7.4 and want to be able to buy stuff worth $190. so you can play with Current I and Voltage V but P never increases.

[@chergaoui.en2roues]

@@robojax Thank you for the clarification, I really appreciate it.

[@s6a6n6d6m6a6n]

I have the same unit - but upon testing I found that the potentiometer does not do anything. This unit is merely functioning as a pass-through. Something's not working - no matter which way i turn the pot, and for how many ever turns, VOUT is always the same as VIN. Since they're so cheap, i ordered a bunch more. Likely a faulty unit, but any ideas till i get the next shipment?

[@robojax]

I faced the same issue and was thinking exactly the same way (mentioned in video) that you have to turn it at least 15 turn before you see the affect. I even opened a ticket to get refund for the item but the seller told me to turn it at least 15 turn and it worked.

[@s6a6n6d6m6a6n]

Robojax yeah 15 turns is not the problem, I must've turned it 300 times in either direction, but VOUT does not change. I've even measured the resistance of the pot at various turns and it seems the wiper effect is working. I suspect a bad transistor perhaps, cuz this version has a crappy tiny one, not the big xl6009.

[@robojax]

I don't know. it could be many thing could go wrong.

[@mahound9]

I'm having the same problem. Vout is .1V lower than Vin. Trimmer does nothing. I've tried grounding it, I've taken the chip off and swapped it around backward... Seems like my batch of 5 arrived with dead chips. Perhaps something happened during shipping when it was x-rayed by customs? Let me know if you have any developments.

If we input 5volt and out 9volt What will be maximum current?

[@robojax]

I believe that is exactly why I made the video to answer these types of questions. so please watch and come to conclusion.

[@bhajo16]

Hey Robo, Can i use it at 5v 2A to 9v 2A im planning to use it to power my guitar pedal board with 5 pedals 600mah each.

[@robojax]

No you can not. The power you are providing is 5V and 2A, 5x2=10W, and you are expecting to 9V and 2A which is 9x2=18W. You can get 10W if efficiency is 100%. In this case you will get less than 10W.

AOA bro. i m trying to use this module to charge battery.inpu voltage is 3.5V. i m using piezo electric plate to get voltage but this module is not working. when i connect this module suddendly voltage drops to half even on the input side of the module. can you plz explaint his to me. what should i do?

voltage drop can be two things. 1- faulty module 2-you are overloading this module

No has comentado que tiene un consumo interno. Yo lo uso en un Receptor de RC para subir de 4,2 a 6V .Es una pila de LI 1906 y si lo dejo sin usar el voltaje de la bateria con 1 mes cae a 4.00V en lugar de mantener los 4,2V ....Saludos

[@robojax]

Sí tienes razón, no lo mencioné porque es muy mínimo. La regla es que pones el interruptor entre la fuente de alimentación y la batería y la apagas cuando no la uses. Además, UN mes es mucho tiempo y, dependiendo de la calidad de la batería, también pueden perder carga. Gracias por el comentario. Saludos desde Canadá

Can anyone tell me what will be the value of R1 AND R2 if we want to get fixed 6.7V output not using rheostat to adjust.Input is 3.7-4.2v

[@robojax]

here on page 6 of datasheet, there is formula for Vout. you need VREF which says is 0.6V. So you pick your let's R2 10k ohm and find R1. you can use also online calculator to find the unknown.

[@minravex9919]

is it possible to hook it up to the led without xl4015

what you do mean by "without the xl4015"? LED needs power and this module provides it. Just set the volage of your LED and it should work.

I bought 3 of those very modules from ebay - none of them seem to work, I tried 5V USB in and get out 4,7-ish volts out, turning the adjustment pot (multiple turns!)does absolutely nothing, stays at 4,7V. On Tried 9V battery as input, the same behaviour on all three modules, am I doing something wrong o_O ? I'm not a total electronics noob and double-checked polarity in/out side..

you have to try and rotate it. This exactly what happened to me. I have over 10pcs and almost giving up thinking they are all bad. But they worked.

reduce the load capacity. if this module can handle only 1A and you connect 2A, it will shut off.

I have an battery that puts out 5v with this thing it only goes power down and not higher like 12v what should i do?

I mentioned in the video that you have to turn it 10 to 15 times before you see any changes. If that doesn't happen after few tries, then the module is bad.

now this is what i call a test, well done! So if i have a variable 2-4V@60-400mA imput, can this board hold a Voltage of 6V or will it change if the imput Voltage is unstable?

at 01:14 (click to watch) I have shown that 2V is at the very edge where the module will not work. At 03:00 I have explained that the output is stable even if you change the input.

Hi, calculate the input power 3x5=15W and the output power 14x1=14W output is less than input, so it should work. See my test as I don’t remember what value was on he current at that voltage. If it is 1A output then you bare good.
