There's a MicroUSB plug on one end and a 5.5mm/2.1mm DC barrel jack with center positive polarity on the other. This allows you to&nbsp;connect one of our&nbsp;5V 2 Amp, 5V 4A or&nbsp;5V 10 Amp&nbsp;adapters to something that expects to connect to 5V USB. We also have a cable-version of this, but this one is compact and cute!  Since this&nbsp;does not have any resistors or other connections inside for the data lines,&nbsp;this won't work for charging an iPhone, iPod or iPad or other device which expects some sort of resistance on the D+ and D- connections. It does, however, work great for Arduinos, BeagleBones, Raspberry Pis, many generic cellphones &amp; Android devices, as well as most other USB-powered gadgets.  There is no regulator or voltage protection in this adapter. If you plug in a 9V or 12V power supply in, you could destroy something expecting only ~5V so be very careful!
