The difference between the compatible and non-compatible devices is USB and Firewire. The iPhones are not able to connect to the firewire devices the iPods still are. The Firewire voltage is 12v which is why it is popular with in car charge devices because there is no need for changing the voltage, the power in a USB device is 5v. I am not one to always buy the most expensive choice but in this case you may get what you pay for and not have the correct voltage at the end of the USB connector in the bargain version. Would this damage the iPhone? I don't know but I would let you test if it affects the life of the iPhone or reduces the life expectancy of the battery.

The price is at least low enough to warrant a gamble. --- MUGLO information at <http://www.freewebs.com/muglo> Manage your account options at <//www.freelists.org/cgi-bin/lsg2.cgi>
