Wall Adapter Power Supply - 5VDC 1A
sku: TOL-08269
Description: High quality switching 'wall wart' AC to DC 5V 1000mA wall power supply manufactured specifically for Spark Fun Electronics. These are switch mode power supplies which mean the output is regulated to 5V (no more 14V outputs!) and the capable output current is much higher (1000mA!). Please note, this specific supply (5V/1A) is also FCC/CE certified!
These will power most projects that don't require more than 1000mA of current. Center-positive 5.5x2.1mm barrel connector.
Works with 100-240VAC inputs.

I ordered 2. The first one was Dead on Arrival.
Installation instructions:
1) Plug into wall
2) If no red light on power supply throw in trash
(Confirmed no output voltage with DMM)
Not worth shipping to try to send it back.
The second unit appears to work.
Output Voltage is 5.24V.
Switching frequency is 100kHz (about 100mVp-p switching noise on scope).
