## Description

##  Description 

[Put your Snap! cassette on and sing along to "I got the power!"](https://www.youtube.com/watch?v=j1BNcSBApOU) with this super useful power supply adapter where you can easily change the voltage with a snap of your fingers. On the front are a potentiometer knob and a LED 7-segment digital display. Twist the knob and look at the output voltage to range from 3V to 24V DC. It's kinda like a benchtop supply you can take with you anywhere. Or if you don't wanna take it anywhere, it has six mounting holes for a more *permanent* power supply spot.

This **3V to 24V Adjustable Power Supply** comes with a 2-prong plug and a 2.1mm barrel jack. With a [pair of these alligator clip adapters](https://core-electronics.com.au/2-1mm-dc-barrel-jack-to-alligator-clips.html), lighting up any one of Adafruit's 2-wire LED strips becomes a breeze (like our [Flexible LED Strips in Various Colors - 352 LEDs per meter](https://core-electronics.com.au/catalog/product/view/sku/ADA4835) or the [Flexible Silicone Neon-Like LED Strip in Various Colors - 1 Meter](https://core-electronics.com.au/flexible-silicone-neon-like-led-strip-in-various-colors-1-meter.html)).

With all that adjustable voltage, this power supply is a great tool for any maker's workbench for any kind of robotics or electronics project. Adafruit love this as Adafruit's sole desktop power supply when Adafruit don't need current limiting or current measurements, Adafruit can dial it to 3V, 5V, 6V, 9V, 12V, or 24V based on the device Adafruit are working with. You can draw up to 2 Amps at any voltage - so its good even for projects with small motors or lots of LEDs.

We also carry a [Adjustable Power Supply with 2.1mm / 5.5mm DC - 3V to 12V at 5A](https://core-electronics.com.au/adjustable-power-supply-with-2-1mm-5-5mm-dc-3v-to-12v-at-5a.html) and a [3-12VDC 1.5 Amp output switching power supply with a selectable out and range of DC plug tips](https://core-electronics.com.au/compact-switching-power-supply-selectable-output-3-12vdc.html).
