The package contained: the wireless car jack , a micro USB, instructions, and a port for charging. The transmitter is Fm, so you'll have to turn the radio in your car to Fm. On the transmitter is: the 3.5MM plug, on/off switch on the side, screen, previous, next, and the MIC. It has a built in lithium battery which has a battery life of 4 hours, and the recharging time is 2 hours. It is compatible with iPods, iPhones, smartphones, MP3's. etc... The transmitter also has a hands free talk function which makes it a lot safer to use.  The transmitter gets full frequency range (87.5~107.9MHZ). The transmitter is really light weight and compact  it only weighs 20 g. Overall, this is a great transmitter, it has a great design, and is really easy to use. The instructions come in English and Chinese, and are really easy to follow. The transmitter isn't big, so it doesn't get in the way when using your mobile device, and because of its small design it makes it really easy to store. I give this 5 out of 5 stars, and highly recommend.
