Powering car LEDs via USB Answered
I've always wanted to make my car (my parents car :'c ) a little bit more fun, It's a 10/11 year old ford fiesta without Bluetooth/USB. Here's what I would like to do, just wondering if anybody can see any problems with this. I know very little about power or how electronics work.
I want to be able to skip songs and answer calls without having to pick up my phone, for that I am going to buy this: https://www.amazon.co.uk/gp/product/B01E3UC59Q/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=AP087GSGD7Y0R
Now this will use my cigarette lighter for power which is fine until I get to my next part.
I also wanted to put LED strips under each of the seats, and for that I would buy this: https://www.amazon.co.uk/Possbay-Interior-Atmosphere-Decoration-Sound-activated/dp/B017VSY3RY/ref=sr_1_3?ie=UTF8&qid=1477573217&sr=8-3&keywords=car+accessories
As you can see, that also requires the use of the cigarette lighter. What I want to do to get around the problem is buy this "1M USB DC 5V To DC 9V 12V" cable and also plug that into one of the USB slots: https://www.amazon.co.uk/2-1mm-Module-Converter-Barrel-Connector/dp/B01G56J4I6/ref=sr_1_2?ie=UTF8&qid=1477573430&sr=8-2&keywords=usb+5v+to+12v. Do you reckon this is possible? Are there any obvious problems with what I'm trying to do that I may have missed/not be aware of?
