  • I was surprised that it works.

    A relatively large voltage range. Increasing the drive worked on the first try.
    When the need for constant output voltage for a wide variety of input values??, the product seemed ideal. Very simple to set up with great sensitivity. Easy wiring. With a bit of caution must operate on the first circuit.

    - It has good stabilization of the output voltage. When i have supplied it with 12V the output stayed constantly at 4.99 - 5.03 volts regardless of the output current which was between 0.5A to a maximum of 2 Amps
    - A small switch would be a good addition to it when using in the car, or at least connecting it to a switched plus is a good idea to prevent it from running idle and flattening the battery.
    Very good DC power supply, with stable voltage. The price could be better though.
  • Upconverter works well

    Works well. I'm using it as a USB to 12V DC converter to avoid carrying (and caring for) an extra battery for some laptop accessories that use 12V. In this case, a TNC (computer to packet radio interface)
    Solder pads are large and located on the corners of the board, making connection very easy to solder, even if you aren't very good at soldering. The completely inept could still drill and bolt wires on if they had to.
    I will buy more when I need them.
  • Works for me

    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.
  • Very good step up converter

    Handles 5+ amps of current (all my supply can put out) and boosts voltage well. Good regulation. Measures about 91% efficient. Small and compact. Has decent heat sink.
    Gets to 185 degrees F at ~3 amps input continuous at room temp (75 degrees).
    Overall a nice little unit, but don't expect 5 amps continuous with that heat sink. For the price it can't be beat.
