Description: This is a high quality switching ‘wall wart’ AC to DC 5V 2000mA Barrel Jack wall power supply manufactured specifically for SparkFun Electronics. These are switch mode power supplies which mean the output is regulated to 5V and the capable output current is much higher (2000mA).

These wall adapters are perfect for supplying power to many single-board computers like the pcDuino, Beaglebone Black, or the Raspberry Pi. Please note, this specific supply (5V/2A) is also FCC/CE certified and works with 100-240VAC inputs and has a Center-positive 5.5x2.1mm barrel connector.

Customer Comments

  • Just wanted to point out that if you want to use this to power an Arduino, it outputs 5V. If you go into the arduino with 5V, your VCC will only have about 4V due to a 1V drop from the regulator. Not a problem with this product, but something I got confused about

  • The 230V capability is for us Europeans not a real advantage, since we would have to pay a few dollars for a power plug adapter anyway.

  • How long is the cord?

  • THANK YOU for carrying this 2 amp power supply! I’ve been looking for one like this and now you finally have it! already ordered.

Did the job

Good quality, worked like a charm.


Great deal, great price

removed board from case for prototyping use. Was adequate to power 1.5A system. No PCB mounting holes, but it’s not designed for that. Great power supply awesome price!
