Customer Reviews

  1. Review by Michael verified purchaser

    Great little unit. Set and forget. Good solder pads, and is easily tucked away in some out-of-the-way corner.
    Mobile Phone charging is hit and miss but this is probably issues with the phones themselves being too picky. (Posted on 14/03/2019)

  2. Review by Thomas verified purchaser

    Works exactly as expected. I'm using this as a power supply for a Raspberry Pi 3 with a LoRaWAN RAK831 chip. I'm using POE, so I'm taking 24V in and stepping it down to 5V for the Pi. Runs fine, stays cool, so much so that I didn't even need the heat sinks (it is only slightly warm to touch).
    Excellent solution for the price.

  3. Review by Dale verified purchaser

    This is a great little power supply. I like the fact that it has a wide input voltage range. (Posted on 9/08/2018)

  4. Review by Reid verified purchaser

    Solid solder points. Very compact. If you're looking for something with a bit more wattage I recommend this:

  5. Review by Tek verified purchaser

    Awesome little performer. I use it as a 12v to 5v dc to dc converter. It drives a backup battery charger, arduino, and a powerful LCD screen without any problems. Doesn't even get warm after battery has charged up. (Posted on 17/08/2017)

  6. Review by Paul verified purchaser

    Small and simple. Works a charm. (Posted on 12/07/2017)

  7. Review by Case verified purchaser

    This product is exactly what I needed for my project. (Posted on 29/06/2017)

  8. Review by Ben verified purchaser

    A practical board that has many uses, seems to be of good quality but i have only run it for about 100 hours so far. Make sure you set the required voltage before use. (Posted on 22/11/2016)

  9. Review by Alex verified purchaser

    Great product, when used appropriately! Note the following well;
    -it is a buck converter (it will only step down the voltage not up, 4V in will not give 30V out).
    - it has drop out, eg. 12v in cannot give 12v out, you might squeeze 11.8 out of it if your lucky.
    - at high currents it will get hot ... very hot!
    - it's standby current is quite high so it's not ideal for battery powered projects (Posted on 4/10/2016)

  10. Review by Neil - Well worth the money verified purchaser

    Basic, cheap and functional. These are a must have in your toolkit. This gives you enough range in both the Voltage and Amps to power most small projects with different power needs.

  11. Review by Michael - Easy to use with low power consumption verified purchaser

    Easy to solder pins (for breadboarding) or wires to. I measured 7mA current draw with 5V output into no load and 65mA into a 100 Ohm load, better than a simple linear regulator. (Posted on 9/02/2014)

  12. Review by Shane - Compact, Stable and Convienant verified purchaser

    Terrific small regulated power supply ideal for small projects. Have bought a few just to have to cover any psu requirements on small to medium projects. Ideal for running Arduinos et al. (Posted on 2/10/2013)

  13. Review by sgtech - Stable power - good build quality verified purchaser

    Comes with mounting holes for a neat project finish, depending on the input voltage it can run a bit warm but benefits from a small heat sink. At this price buy several. (Posted on 26/07/2013)

  14. Review by xcontrol - Clean, well finished

    Great basic supply for projects, good layout of connections and nicely finished off. (Posted on 1/05/2013)
