This 5V 1A USB power supply has a USB 'A' port where you can plug any USB cable in. This adapter is great for use with an Arduino, Lower power versions of the Raspberry Pi, Teensy, Circuit Playground, etc.!

This adapter was specifically designed to provide 5.25V not 5V, but we still call it a 5V USB adapter. We did this on purpose to solve a problem that occurs often with USB-powered gadgets: they draw so much current than the resistance of the cable causes a voltage drop, so instead of 5V, the device sees 4.75V or so. To avoid this problem, this adapter is produces 5.25V
