This adapter has a standard USB 'A' connector for the output so you can power your Arduino, Raspberry Pi, etc. through a USB cable. It was specifically designed to provide 5.25V to prevent a problem that occurs often with USB-powered gadgets when they draw so much current causes the voltage drop to 4.75 or so due to the resistance on the cable. With this power adapter, you can power the Raspberry Pi and other gadgets at full load while maintaining the output voltage close to 4.9V.
