Hi I recently bought an ipad 3 (used) but it did not come with a charger. Since this is my first ipad i assumed that it would charge like a regular ipod with the usb cord connected to the PC but from a little research i found out that it will charge the ipad but very slowly. The correct way of charging it is using the 10w usb power adapter that came with the ipod if bought new. But then I read that the new ipad 4 came with a 12w power adapter and of course charged the ipad a lot quicker. So my question is, is it okay to use the Apple 12W USB Power Adapter on the iPad 3? or should i just buy the 10w power adapter. Also would you guys recommened me to buy the original Apple power adapter or would a different brand make a difference? thank you!
