    Hey welcome to the forum! You could prolly get away with using this http://store.mp3car.com/DCDC_USB_Int..._p/pwr-047.htm or if you need more power http://store.mp3car.com/Carnetix_CNX..._p/pwr-010.htm both will give you auto shutdown the first one needs to have the power set via usb to the 20v Hope this helps SNO
