In principle: Yes 1, the internal reception function of the mobile phone, put directly on it! It is said that some should pay attention to the location!
2, there is no built-in receiving function, add a small receiving device can be! There are general purpose models and special models.
3, like apple can not open the back cover, but also need to add a back cover or holster. The gods have tested it! One thing to note is that your charger plug output is best: 5V-2A. Look at a few brands to know that many mobile phone charger plug is: 5V-1A. Not enough output, not enough power. Of course, the charge is slow!
