Un smartphone est composé d'une bobine de recharge en cuivre qui constitue le récepteur de la recharge. Un chargeur est quant à lui composé d'une bobine de cuivre qui est le transmetteur de la recharge électrique. Lorsque ces deux bobines sont alignées, un champ électromagnétique se créé et la recharge électrique peut alors traverser les deux bobines et vous permettre ainsi de recharger la batterie de votre smartphone.

Non.

Une fois le chargeur sans fil branché sur une source d’alimentation, tout ce qu'il vous reste à faire, c’est de poser votre appareil mobile dessus en vous assurant qu’il est bien centré. Et la recharge démarre aussitôt. Cette dernière est indiquée par un voyant LED ou par une animation sur l’écran de votre smartphone.

Les stations de recharge à induction utilisent une technologie de recharge connue sous le nom de Qi. Cette technologie transfère l’énergie électrique de manière sans fil, du chargeur vers l’appareil à recharger. Tout se passe entre deux bobines, celle se trouvant dans le chargeur et celle intégrée à l'appareil à recharger. Ce phénomène génère un champ électromagnétique. La plupart des chargeurs à induction utilisent le protocole de recharge sans fil Qi qui permet la communication entre le chargeur et l'appareil à recharger.

Les stations de recharge sans fil fonctionnent comme les chargeurs à induction, à la différence près qu’elles permettent de poser l’appareil mobile de façon inclinée. Elles utilisent une recharge par induction qui consiste à transférer l’énergie électrique de manière sans fil, du chargeur vers l’appareil à recharger. Le chargeur possède une bobine de cuivre qui créé un champ électromagnétique. L'appareil mobile dispose d'une bobine similaire qui réceptionne ce champ électromagnétique pour recharger sa batterie. La plupart des stations de recharge utilisent le protocole de recharge sans fil Qi qui permet d'optimiser le processus de recharge en ajustant la puissance et la vitesse de recharge. Ces stations de recharge ont la particularité de positionner l'appareil en mobile de façon inclinée.
