Whenever i used my original BlackBerry car charger on my Z10 i got the message on the left. I was always wondering why as it was an original BlackBerry charger i am using.
I now found out that you need a special car charger to charge the new phones properly while driving. The 1.8A BlackBerry Premium charger does this.
It is a double charger which has one connection free for a USB cable. I will have to pass by the BlackBerry Store in the Dubai Mall the next days to get one. You can buy the charger here on Amazon : (LINK)
