It has a red LED indicator which will turn blue when the unit is charging. It is about 7 cm in diameter and has a white USB cable with 82cm. This can sometimes already be a bit short. It is gummed up and down in a ring shape. The upper rubber ring can be seen in the photo. The lower rubber ring prevents slipping, the upper sliding the device when it is located.
Important Information:
1. When the cover away from the phone. It is seen that in the cover one coil is incorporated in an area of about 6 x 5 cm. This sector of the phone should be placed almost exactly on the charger.
2. It may take a bit until it begins to load and then often comes the message "Place the phone in the middle of the hot-zone". The note by one click ignore.
3. I am using a SPIGEN SLIM ARMOR Protective Case and it goes well with this protective cover.
Correct placement is everything. Just as in marketing.
