I think I can delegate most of my crappy wall-wart adapters to secondary projects, and use a few of these to power up my immediate projects. It’s a very useful, flexible and capable power supply. More portable than a benchtop supply, and at this price, definitely more useful!

  • Pick your required voltage from the 6 position slider.
  • Pick what tip you need for your project. Standard 2.1mm barrel jack not your requirement? How about a 2.5mm? No? There’s a total of 8 to pick from (but no 9V rectangle battery connector, sorry).
  • Need tip-positive, or tip-negative power? Doesn’t matter – swap the jack position around to get what you need.


  • Multi changeable plug DC-cord.
  • Input 100V to 240VAC, 50Hz/60Hz (North American style plug)
  • Over load, over current, over heat protection.
  • International approval CE EN60950, UL1950, CSA22.2 No.950.
  • EMC approval EN55022.
  • Extra low consumption during standby (very little power wasted when it’s plugged in, but doing nothing)
  • Weight: 86g
  • Size: 67x29x74mm.
  • Cable length: 1.54m (60-3/4″)
