What Rasta was getting at is that you need to specify what power your rig requires...that would include what voltage do you need and what is the current draw?
Also, what is a micro BR? I'm not sure what that is so does it require a special power pack or can it be connected via an external cable with a connector that fits your device. Things like this. The more specifics you provide, the better answer you will get to your question.
Nobody can help you if they have to guess about what you're asking.
