The charge states are displayed using various colors on the upper side of the charger.
That's a nice touch, then you have not always look to the iPhone that the battery is full, but just wait
until the color "green" changes.
Why then was no 5 stars?
Because the charging cable is unfortunately fall far too short. Over the radio I have a specialist, because the iPhone fits in with the cable just so.
Even after repeated use is only a small linear expansion determine.
Too bad if the cable would be longer, it would be the perfect charger.
