WorthTrust Wireless Rechargeable 3.5mm Jack Stereo Radio Car Fm Transmitter for Iphone 4 4s 5 Galaxy S2 S3 HTC
This thing is nice and portable and can be used on any device with a 3.5mm jack on it and also has a rechargeable battery. However the transmitter on this thing is god awful, you cant listen to the thing without hissing in the background. Even on channels with no stations on them this thing cannot compete. Save your money this thing is a waste of your time and patience.
