Hello, I'm using a PointOfView P742C and it needs to be always ON, I have DC charge cable (>500mA) always connected, and when I connect the USB cable and start communicating it stops charging com DC cable and starts charging from USB cable (at ~500mA)... Eventually it drains more than 500mA and drains all the battery and power off... How can I force fast charge on USB, or force it always to charge from DC cable? I do not understand why it have a DC port, if it chooses from USB port when have both connected... Thanks for any tip.
