I used this DYI to put a 12v cigarette plug on my bike today. It runs my little air compressor just fine but when I put a usb adapter in it the fuse blew. Also, my phone car charger won't work in it. What do I have to do / change to be able to use a usb adapter and phone charger? Any help is appreciated.
