You power calculation is a little of. Your input voltage (5V) times the shown amperage is the true Wattage for the load + the voltage converter. So if you crank the output voltage up to let's say 15V and the amperage show is 300mA, the total power consumed is still 5V × 300mA = 1.5W and not 15V × 300mA = 4.5W. The current through the load (when neglecting the current used by the converter) is 300mA × 5V / 15V = 100mA. So the power dissipated by the load is 15V × 100mA = 1.5W. This is according the input voltage (5V) × input current (300mA) = 1.5W.
You are so wrong. if output shows 15v 300ma that means 4.5w (p=v.i) .. it means input its 5x900ma=4.5w.. watts are same input and output.. energy cannot be created or destroyed, but only changed from one form into another or transferred from one body to another.
@@josuedanielmartinezsanchez4540 Exactly my point. The current reading was at the 5V input, so 5V × 300mA = 1.5W. And yes, energy on the input should be equal to the one at the output. When the measured output voltage is 15V, the current through the load (which was not measured in the video) should be 1.5W / 15V = 100mA.
@@josuedanielmartinezsanchez4540 Hacktuber measured the current at the 5V USB side and not on the load side, but multiplied the input current by the output voltage. This is not correct. You are correct that the power on the input should be equal to the power at the output. With 5V, 300mA at the input, the output current at 15V should be 100mA.
@@jansmit4628 i answer before watch the video hehe, yous aid.. (for example, no based on video) "output voltage.. lets say 15 v show 300mA" so i calculated on that... 4.5w hehe...
I am a beginner working with electrical modules so your UA-cam videos have been very helpful and informative getting me started. I also teach at a Juvenile Detention Center some young men who have not had good family relationships and many of your projects are on my schedule to show them so they learn a little about soldering and components. Keep up the good work and I will keep watching so I can get more ideas on what I can learn and pass on to others!
Put a multimeter in series with the output load so we know output current. Output and input currents are not the same, when you multiplied output voltage by input current you got a meaningless power. Measure both currents and we can see input power, output power, and efficiency by dividing output by input power.
What interests me is the voltmeter display - there must be a microcontroller and resistors inside what looks like a 3 digit display. I just checked and the 3-digit voters are available for sale. 😊
Nice device but low amperage! Assuming 100% conversion at 10 V your 2 2A would become 1.1 amp & 20V. will be 550 mA. But we lose about 15% in the buck conversion. We can still have a decent trickle charge at about 400 mA - 450 mA. Not bad for a buck 👍
Another Aliexpress jewel - Thanks for bringing it to our attention ! Could you find a way to get the part under review in the Title please ? You vids are impossible to find later & believe me I've tried.
This thing taps out at 3.2v on an admittedly, fairly power hungry led. I havent studied it yet but i presume it has some sort of protection chip so you dont cook your items, 🤷🏼 Still a pretty good little buck convertor for under $10
Wow, this is absolutely amazing! It's incredible how such a small and affordable module can deliver such impressive results. Thanks for sharing this brilliant find! 👏✨
Wow - this is really a nice little device for variable voltage on the way just for 1 Buck!? Unbelievable + shipping i guess? The voltage display is not very accurate though, but what will you expect?
Does the output voltage change with the input voltage? e.g. If the Input voltage was from a nicad battery whose voltage drops over time and the output was set to 2 volts, would the output voltage change as the battery voltage changes as it discharges?
my friend, you have many spectators here in Brazil and Portugal. If possible, is there a way for you to post subtitles in Portuguese? it will help us a lot. Thank you for your work and sharing your knowledge with us. God bless you.
We need to see the output on an Oscilloscope to see what crap is in the actual output, because its certainly not a clean DC output voltage with only those components on that PCB. How bad is the AC component waveform????????
Do you think i can used to build an easy power supply for my 5 meters LED strip around the wall? Plug to the wall the right phone charger so connect this one (trough usb) to the Buster you showed setting the right voltage straight to the LED strip?
You can not calculate output Amps like that. There is no free energy. Only the usb meter that gives 5V x 0.5A=2.5W is correct and this is also the max output.
Don't change the input energy on the outuput! Not a single joule has been lost since the Big Bang, when the universe was created. Then you can be sure that it is the same here and that the laws of the eternal universe still hold true.
Two questions: firstly, how much profit does AliExpress make on this item after delivery? Second, how much profit does the manufacturer make as well? However, if we really want to put things into perspective, then how much would this item cost if it was made in a western country such as England, Germany, Australia, or the USA? And let's not forget the postage costs!
Well, if you divide the power (3W) by the voltage you need, you'll get the maximum current (it's the law 😉). At 5V will be a current of about 0.6 A. At 9V will be 0.33 A and so on... For (very) small applications it's a good choice.
you can use a power bank with the module to charge a car battery in about 5 days and then use the that car battery to cook your glass of water! hope this was useful!

Thank you, I’m going to buy one as I need to power a very bright 12v led from a power bank, this should step up the power. ❤
I think will work
Thank you for this review. This is a product that I have been looking for!
You're welcome, have fun with it!
8:05 I think it draws 0.56A * *5V* = 2.8W, so it's maximum 0.93A @ 3V on the output. Am I right?
Great finding BTW! 👍
Yes prob 1A is max current
I used basically the same thing, powered it with a TEC on a heat sink to charge devices in the woods, just need a heat source.
Nice! That's a very clever use of it.
This thing taps out at 3.2v on an admittedly, fairly power hungry led.
I havent studied it yet but i presume it has some sort of protection chip so you dont cook your items, 🤷🏼

You can not calculate output Amps like that. There is no free energy. Only the usb meter that gives 5V x 0.5A=2.5W is correct and this is also the max output.
I assume it is a MT3608 in a SEPIC configuration?
The inductors are tiny??? A single coupled inductor would have been better.
🤔 Me too wondering?

Once they sold millions...
Aliexpress will not open in English, only Dutch. I will be buying from Bangood.
You don't know how to read Dutch?? 😅. No problem with mine, English is working.
Its same,just order it and make experiments
and you say nothing about amperage.
of course its going to be peanuts of amperage! if it was amperagely powerful it'd be classified as a free energy device!
Well, if you divide the power (3W) by the voltage you need, you'll get the maximum current (it's the law 😉).
At 5V will be a current of about 0.6 A.
At 9V will be 0.33 A and so on...
For (very) small applications it's a good choice.
Output power:
Input 1.2-2V, output power within 2W;
Input 2V-2OV,output power within 3W;
Input 20V-24V, output power with in 2.5W;
Would have been great to see the device go all of the way up to the highest voltage
At 24v will give around 20-30 mah
Wonder if you could run a 24v water cooker through it via a car lighter socket.
Not possible at all😔
you can use a power bank with the module to charge a car battery in about 5 days and then use the that car battery to cook your glass of water! hope this was useful!
