The USB specification limits current consumption to a max of 500mA from a USB port so if more current is required a suitable power supply is needed. It also features a generous cable length of 1M.

    Hello Pat,

    Thank you for your question.

    I have taken a look and the DC plug supplied on this cable is a standard straight style connector and not the 'tuning form' type.
