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.

Note: These wall adapter power supplies may only output 4.5V when pulling a full 2A. Please keep this in mind when making your purchase.

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.

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!

Does what it should

Works perfect, no issues whatsoever.

Works well, feels a little wonky

Works exactly as expected. Very consistent voltage so far, though where the cord enters the casing it seems a little “loose” and rattles a bit, but I expect to have it fairly fixed and doing foresee any actual problems.


One works great the other one had an internal short and burned up on the first plugin

Sorry about that. Contact us and we’ll be happy to help you. https://www.sparkfun.com/returns
