Adafruit Adjustable Power Supply with 2.1mm / 5.5mm DC - 3V to 12V at 5A

Put your Snap! cassette on and sing along to "I got the power!" with this super useful power supply adapter where you can easily change the voltage with a snap of your fingers. On the front is a potentiometer knob and a LED 7-segment digital display. Twist the knob and look at the output voltage to range from 3 to 12V 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 3 to 12V 5A Adjustable Power Supply comes with a 2-prong plug and a 2.1mm barrel jack. With a pair of these alligator clip adapters, lighting up any one of our 2-wire LED strips becomes a breeze (like our Flexible LED Strips in Various Colors - 352 LEDs per meter or the Flexible Silicone Neon-Like LED Strip in Various Colors - 1 Meter).

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. We love this as our sole desktop power supply when we don't need current limiting or current measurements, we can dial it to 3V, 5V, 6V, 9V, or 12V based on the device we're working. We also carry a 3-12VDC 1.5 Amp output switching power supply with a selectable out and range of DC plug tips.
