dc to dc step down Customers Reviews

  • Very good device

    posted by bitsnapper

    The converter is very easy to use after having understoof the dip switches. It offers good efficiency and doesn't get very hot at loads of about 1.5 amps.
    If you are familiar with voltage converters, it should be no problem to use it. Just connect a voltage meter to the output and see what happens if you use the dip switches to adjust the output.
    Very useful and reliable for any purpose. I used it for supplying a reduced voltage of 8 V to the red part of a RGB LED chip in combination wit a self made RGBW controller. Works better than a resistor for current control.
  • Good thing

    Easy to connect the battery holder, just use slot screwdriver; Does not heat with 1A load; USB output;
    I used it to power a Raspberry Pi off 3x18650 batteries. Got 4+ hours with uncharged batteries (they were new, charged by the factory).
    Great product to power your mobile device.Why does review have to be so long? Why does review have to be so long? Why does review have to be so long? Why does review have to be so long? Why does review have to be so long? Why does review have to be so long?
  • DC Voltage Regulator

    posted by NektariosSp

    Great piece. Quite useful. Not possible to build one, using ordinary 7805, cables and a USB socket. Works fine, but I have not tested it running to the current limits. Great for installation in cars, DIY projects and of course, for connecting any USB powered device.
    I have no other thoughts.
    Good to buy. Nothing special needed for installation.

    well made , nice unit. works well as a fixed 5 volt output unit supplied to me ( instead variable output ordered )
    i will need to buy another variable voltage module but how will i be sure that i will get it , instead of fixed voltage type i was supplied.
    if i can get an assurance that i will get the variable output, then i will order it
  • Nice driver for 10W (3x3) LED

    posted by dielomat

    It does what description says...using 12Volt source i measured 0,76A current with a 10W LED (3x3 type ) - thats almost exactly 9W.Driver gets warm, but ist still touchable without burning fingers after 1 hour running.
    i think in warm environment it will be better to use a cooling plate.maybe tearing off the rectifier would give lower temps and higher efficiency
    The driver is usable for 10w LED like SKU: 39957 Ill sure order some more soon.
