    You do realize that the little push button switch closest to the outlet side allows you to stop the scrolling of the meter at either input voltage, output voltage, amps or current. The little push button close to the input side turns off the LED's. Thanks for the nice review.

    you realize you can stop the LED screen from constantly switching between all the input and output parameters.

    I cut the video when he said "it has and LCD..." People with no or minor knowledge on electronics should refrain to upload videos as it misleads people wanting to learn or looking for information.

      Couldn't agree with you more (along with too many "maybe's..I think...I believe..probably's & even a 'Sh*t' thrown in for good measure) He does not even know HOW to use the unit let alone edit a video. Unfortunately knowledge and experience is not a requisite to uploading to YT :(

      @@superburritotime8720 I too am trying to understand how this thing works. A novice like this really does need to understand what he's doing so's not to misinform the viewer and potentially ruin a project. The way to encourage him is to advise him to, as they say, "do some proper research first". Imagine if you were taught at school by someone like this. Let's hope he's done just that over the last few years.

    hello, I would like to power a camera back between 3.7Volts and5volt (380Mah max). when I go to adjust the step down in + -3.7Volts how many amperes I would have in output?

    Hi NightFlyyer, very helpful video, but this unit states it can charge Lipo and Life batteries .
    But how do you charge lipo without the balancing plug??? All lipos and life have to plugs.
    A balancing plug and the main plug

    Where have you ordered? Check the output short-circuit? And when the overload current is exceeded - what happens?

  • @dnunez1985
    @dnunez1985 7 лет назад +1

    what happends if you shortcircuit the output, and then power up the module? It still regulates on cc? for example, set current at 2 amp, when you short the output, it got to show 2 amp. If yo unplug and plugin the dc-dc converter, it still regulates at 2 amps?

    Assuming I supply the module with 12V, set the module to 10V, if I reduce the input voltage to 10V, which output voltage do I still have on the module (Output) ?

    Hi guys!
    I buy this module. it was great, but I wonder how it can display the voltage ?
    And how does it connect it?
    Thank you...!

    Hi,I bought this converter from china ,but I dont know what is on display the ....P?
    If press right button is:
    input voltage ,output voltage,output current and the ?P(1.2P,2.4P ...)
    !!!! And very important: !!!!the USB slot not constans 5V, this same as output.
    You must first setup to 5V, if want charge mobiles etc... I dont set and my tablet ruined.
    Good video ,thanks.

    Hi,
    I am not sure about electronics. I need a 12v dc in to 5v dc out up to 5amps. Will this work? Also, what does the 75w do?

    I'm not trying to ruin your day, but these onboard Chinese led readouts are never accurate and then you test it with your best volt meter and that has a different reading so now what? Yo rush around the house to find a Samsung phone charger and you find a different reading, but it seems more accurate to the ratings on the charger, but you go to check the amperage and you get zero's well that's because you have to short it to find the amperage and higher quality chargers have a protection circuit and cheap one's don't! So you can sync your imax b6! How do you know your volt meter is dead on accurate? Did you sync it to a oscilloscope? You can do it by taking the back off and adjust the screw while it's connected to a professional oscilloscope if you have one or take it to a shop then sometimes you can get one of these cheap power supplies that you can sync and some you have to remember the real voltage readings and set it up that way. I had so many of these that over charged my 18650 cells to 4.4v and some 4.0v so this will help.

      Tested the same one with a volt meter.. accurate to the 10th of a volt.
