approximately 200 feetPart 15 Devices Unlicensed operation on the AM and FM radio broadcast bands is permitted for some extremely low powered devices covered under Part 15 of the FCC’s rules. On FM frequencies, these devices are limited to an effective service range of approximately 200 feet (61 meters).
How far will a 5 watt FM transmitter go?
That depends on your antenna design, matching of the transmitter output to the antenna, used frequency and antenna height. I you have a transmitter in the FM radio band with a simple “stick” antenna I estimate you could reach around 10 to 20 km. With a yagi antenna it could be more here the limit is the line of sight.
Will leaving something plugged into cigarette lighter?

What frequency is dangerous to humans?
Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
