## Description

The premise of this MicroUSB to 5.5/2.1mm DC Barrel Jack Adapter is simple. 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 connect one of our 5V 2 Amp, 5V 4A or 5V 10 Amp 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 does not have any resistors or other connections inside for the data lines, 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 & 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!
