To charge a Samsung device without a wire, use a wireless charging pad. A Samsung device can be charged with a charging pad only if it is Qi-enabled and compatible with the charging pad.
Not all Samsung devices can be charged using a wireless charging pad because they may not be compatible. The charging pad emits an alternating current through its coils, which set up voltage in the receiving coils of the device. The charging pad must be connected to a power source. When the device is placed in the correct orientation on top of the pad, it should start charging immediately.
