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.
@BingoBongoMan3 жыл бұрын
"...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.

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.

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.

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.
@robojax6 жыл бұрын
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.

Can I use it to have an output of 150mA - 27V with 1.5A - 5V Input. Will it be able to even covert 27V from 5V.?
@robojax Жыл бұрын
it is all about power P, voltage V and Current I. Now P=V*I, input V=5V, I=1.5V, P=5*1.5 = 7.5W and using for output this P=I*V we can find I=P÷V, P=7W because0.5W is wasted as heat. V=27V, I=P÷V= 7÷27=0.259A so yes you can get 250mA. Now remember it is all about power.
@cyclomiha4 жыл бұрын
Hmm. If input is 7.4V, is that chip able to provide 1.5A@12V?
@robojax4 жыл бұрын
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.

first why power drop? if power drop is not due to weakness of sours. This booster uses the power. if the source can supply enough current, it will boost it.

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.

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.
