5V 1A Switching Power Supply w/ USB Port

This is a switching power supply that gives a regulated output up to 1000mA. Has a USB port as the output. The voltage is actually 5.25V. The additional 0.25V compensates for the voltage drop of the USB cord. This is ideal for the Raspberry Pi since you will get better performance when you provide a true 5V instead of 5V minus the Voltage Drop.
