At an external phone Qi-Receiver is used as the Passport does not have a built-in Qi.
Receiver is located on the phone in the case.
Now to the charger:
+ The LED jumps to blue when charging - helps position.
+ LED is fairly bright. That's very good, because the Passport is very wide and you probably could see otherwise difficult to charge state.
+ Shop works even through shell and cover! When the cover is folded, are well 5mm material between charger and receiver. Does not interfere with the charger.
+ Also works on a USB connection, so no power supply.
I am very satisfied with the purchase.
It's also nice that comes a power supply.
Price / performance is good, if still long does ists perfect.
