Those little things you often see at Walmart or Target or whatever other places that use a car's cigarette lighter plug to power them, and use a USB or 1/8 aux cord to send audio from a phone, tablet, etc. to the car's FM radio...
1. Would you get any Part 15 type range out of them at all if you used one of those cigarette plug to wall plug adapters and used them at home?
2. Would they be Part 15 compliant? (it seems like these could be good cheap starter Part 15 FM transmitters until there was enough budget for someone to buy a Whole House or C.Crane)
