Wow, is this not the most useful thing you did not know existed or what? Its a switching wall adapter where you can easily change the voltage! It's like a benchtop supply you can take with you anywhere.
This model is 10 Watts and has 6 selectable outputs ranging from 3V to 12VDC and up to 1.5A output. It has a 2-prong plug, but takes 110VAC to 240VAC so you can use it anywhere with a simple plug adapter.
It comes with a range of tips, such as 2.5mm mono, 3.5mm mono, 5.5mm/2.5mm, 2.5mm/2.1mm, 4mm, etc. You can also change it from center positive (most common) to center negative (less common but seen in some audio gear) You could use this with just about any device or project, it's very handy!
Jargon buster
Plain-language definitions for the technical terms used above.
- center positive
- Center positive describes the polarity of a barrel-style DC power plug, where the centre pin is positive and the outer sleeve is negative. Using a power supply with the wrong polarity can stop the board from working or damage it.
US plug — not for Australian use
This is a US power supply, so it will not work in Australia without a plug adapter and voltage converter. You probably do not want to buy it!
