You can actually charge the iPhone 5 with a regular micro USB wall charger provided you purchase the Lightning to Micro USB accessory from Apple which is sold only in Europe currently. This adapter works only with the new iPhone 5 , iPod nano and the iPod Touch which use the new Lightning connector.
The adapter costs about 15GBP or about Rs.1300 approx , a bit expensive for such a converter but then it is a useful accessory to have if you want to the charge the iPhone 5 using your Android phone’s charger !
Part number is MD820ZM/A
Apple does state that the adapter does work for charging as well as syncing.
Currently I’m charging the iPhone 5 using the wall charger of the Nexus 7! wish me luck ! If this thing works out , I would totally leave my iPhone wall charger back at home.But this Adapter is so tiny , one can easily lose it.
And here is a quick size comparison of the adapter. It is really small and easy to misplace.
