godskitchen 0 Posted November 1, 2006 I want to use the power from the Ashtray light (light is facked) to power a USB powered MP3 player that runs on 5v, i have the Cig adaptor with 5v USB on the end, i was planing to just take it apart and hook up the Ashtray light cables to it.................... Is it that simple? I have had a search but nothing to answer this question........ Cheers! Quote Share this post Link to post Share on other sites
carpy25 0 Posted November 1, 2006 this feed for the ashtray light will be 12v ,you need to reduce the voltage from 12 down too somewhere near 5volts a little over won't make any differance ,the cheapest way to do this is with a resistor from one of the big radio spares companies like "maplins or radio shack " don't wire 12v directly to your mp3 player it will just go bang Rob Quote Share this post Link to post Share on other sites
catch_twotwo 0 Posted November 1, 2006 Surely the cig adapter that has a 5v USB on it should already have the require circuit to reduce the voltage..... :?: Quote Share this post Link to post Share on other sites
godskitchen 0 Posted November 1, 2006 thanks guys, yes the USB does down convert 12v to 5v, well just over 5v but im told it does not make too much difference. Quote Share this post Link to post Share on other sites
Guest Posted November 2, 2006 The cig adapter will be fine, just connect the feed from the cig light to the input in the adapter Quote Share this post Link to post Share on other sites
