Good question. I think the first one is the most universal. From the product page, it says it is compatible for most Apple products: Apple iPad, iPad2, iPad3, iPhone 3GS / 4 / 4S / 5, iPod Touch 4G, Nano 6th. Support all iPad, iPod, iPhone Models. Also Support Samsung Galaxy Moblie Phones, Motolola Droid Family, HTC, LG, Nokia Smart Phones, Amazon Kindle. (White Color, Retail Package). The other two are more specific but seems all good for most recent devices (phones, tablets).
Are those ports available for any apple device?
