Micro USB 5 Pin Male To 5.5 x 2.1mm Female DC Power Adapter

The premise of this Micro USB 5 Pin Male To 5.5 x 2.1mm Female DC Power Adapter is simple. There’s a MicroUSB plug on one end and a 5.5mm/2.1mm DC barrel jack with centre 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 another device that 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.
