dc to dc transformer Customers Reviews

  • Works for me

    posted by GabrielB11

    Cheaper than building it myself here... Since where I live the components are not common.
    Could be cheaper, maybe?
    It is compact and exactly what I needed to have my internet router working on batteries in case of power shutdown!It even has a LED that I find useful to know if it is actually working and I didn't know it had it.Got it encased and mounted in 10 minutes. The other one I made myself took me more than a week since I had to build my own cooper coils, and a generic circuit board because nobody sells them here.
  • Does the job. Cheap & customizable

    Pretty cheap. Wide voltage range. Useful for constructions when you need to get several voltage levels from battery of other lager level.
    Got 3 of them, tested one for cellphone charging - 1A@5V, from battery set of 18V.
    Nice thing. I will perform the test with other voltages&currents I require in my constructions, and then probably buy more of them. Definetely worth the money spent.
  • Great for the price

    Does the job and it's clearly marked with whats + and whats - on the input side.Additionally it's actually providing a stable 5volt output that's within the error margin allowed by USB devices
    Since it can deliver 4 Ampere for a short time (and thus probably around 3 Ampere over a longer period) it would make sense to give it two stacked female USB A ports.
    Worth the price and does the job, though it could use some better documentation and a few bits of components (like polyfuses) for added electronic protection.
