I hardwired a USB hub in my glovebox then I connected my raspberry pi to it then it to my dvd indash. Serves great as not only a charger for up to 10 devices but makes a good data doc too.
Was nice keeping my cig lighter clear and clean look. But that looks pretty good for what you're trying to accomplish
