The last line is the disadvantage. You need the data pins to enable high-current charging. I suppose you could create a digital "transformer" to isolate the iDevice from the port while still enabling high-current charging.

Could you include an inductor to prevent the data bits from changing fast and connect both lines to the power line so that if the power line was actually compromised the inductor would stop the attack.

"The CDL-02POWER is a type A male to type A female extension cable with only the + and - power pins connected.
This is extension for charging devices like ipods, Sat Navs etc. It allows you connect the appropriate device cable and charge the device through your USB port on your PC/Laptop with out opening up your webstore, itunes etc. While a device cable has data and power only the power from the extension is carried through.
Please note that due to limitations of 500ma output from a USB port, some devices may take longer than others to charge. "
