USB is being implemented as a power connection standard more and more these days. But you don’t always have a computer on hand, so how are you going to power all of your sweet USB devices? How about a high-quality switching “wall wart”? This white AC to DC power supply will do 5V at 1A! These wall chargers work with 100–240VAC inputs.

These have a standard USB ‘A’ connector for the output so you can power your Arduino, Raspberry Pi, etc. through a USB cable. Any device that uses a USB cable for charging or power can be powered with this supply.
