I have a FM transmitter that opperates on 12V @ 500mA. Does anyone how how I can "steal" or combine the power from that device to my shuffle. The shuffle opperates 5V @ 500 mA. I want to be able to just plug the transmitter in and then not have to worry about the battery running out on the shuffle or using 2 DC adpters. Does this make since? Can you help?
However, if the FM transmitter needs 500mA and the Shuffle needs 500mA, then something might be starved for power. The is a good chance that it will work. You would have to try it.
Ignore the above post about DC-DC power inverters. That would be better suited to stepping up voltage from 5 Volts to 12 Volts--much more difficult; and it would be a converter not an inverter. An inverter is for making AC from DC.
