The days are obviously numbered for the physical charging cables of the numerous devices that we use - especially for mobile phones.

According to analyses by Information Handling Services, in the near future there will be a vast expansion of wireless smart phone charging. These analyses have shown that, while in 2014 there were 55 million wireless charging devices sold, in 2015 this number will exceed 120 million. By 2024, the industry will be worth over 15 billion dollars. Wireless charging is implemented via inductive energy transfer, where one coil is integrated into the charger (pad), and the second one into the receiver (phone).

Such charging is already available for Samsung's Galaxy S6 and S6 Edge. Nokia used this technology years ago in the 925 model, and it is still available for other models under the Lumia brand. Some HTC and Google phones can also be charged inductively. The solution for phones that do not have built-in wireless charging technology is a special case. Such a solution is available for Apple mobile phones.

But technology is irrepressibly advancing. When more phones can use wireless charging and the standards become more unified, we can expect a small revolution in charging. Other industries will also develop their own technologies. The Swedish firm IKEA has launched its Home Smart furniture collection, which has built-in wireless chargers. A bedside table, table lamp, table, ceiling lights and some other pieces of furniture have the ability to charge mobile phones, and IKEA, as well as some other producers (Qi, for instance), offers charging pads that can be installed in existing furniture.

The second place where we often charge our phones is in the car. Wireless charging for cars is already available in some models from Japanese, European and American manufacturers (GM, Toyota, Audi and Fiat Chrysler). A more rapid introduction into the market is being prevented by the lack of unity among the existing communication standards for charging stations and mobile phones, which is why many car manufacturers are still waiting to launch wireless charging in their cars.
