Well, the title might be awful but bear with me. Yesterday I decided to buy this Belkin Car Charger which has a lightning to USB cable. What I simply want to ask is if I can safely use the USB-lightning cable to replace then one I got when I bought my iPhone 5? The simple reason of why I want to use Belkins cable instead is because it's longer. Now, I thought to myself that this would be no problem since it's the wall charger that actually decides the power output? The original USB cable I got when I bought the phone, should be exactly the same as the one from Belkin, right? "The USB Port is universal, so you can still charge your legacy Apple devices with a 30-pin cable or other devices that use a Micro-USB cable. And the included 4-foot Lightning to USB cable can be used anywhereplug it into your laptop to charge and sync, or use your own wall charger to charge from the wall. Great as a replacement cable or if you simply need an extra." Well I guess that pretty much answered my question and made this thread useless. But what about the fact that this one gives 10 w and 2.1 Amp, while the iPhone 5 wall charger only gives 5 w and 1 Amp? I guess that won't really be a problem?
