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.
