Samsung patent filing reveals a wireless charging pad that could work from distance
A patent application filed by Samsung to the USPTO reveals a dual wireless charger that can charge more than one device at a time using two different methods of magnetic charging. According to Sammy's patent, its dual wireless charger uses both magnetic resonance and magnetic induction charging in the same product. Samsung's current multi-device charging pad employs only magnetic induction. The pad will determine the device that is being placed on it, and automatically use the appropriate magnetic charging method to refresh its batteries.
Magnetic resonance charging is considered the more advanced method between the two. Magnetic induction requires the transmitter (the charging pad) to be placed no more than 7mm away from the receiver (the smartphone). With Magnetic resonance, the charging pad and the handset do not have to be in close proximity to each other,
We could see Samsung introduce its new wireless charging pad in February when the Samsung Galaxy S9 and Galaxy S9+ are expected to become official.
