What is the wireless charger?

Edit:Shenzhen Keliway Technology.,LtdUpDate:Aug 02, 2018

Consumer electronics and mobile phone technology have made great strides over the past two decades, including the introduction of wireless chargers. A wireless charger is a convenient product that can charge mobile electronic devices without the need for wires or plugs. The wireless charger can even easily charge multiple devices at once, saving time and power.

Wireless chargers, commonly referred to as power pads, use a technique called magnetic induction to transfer electrical energy from a wall outlet to an electronic device. The current is transmitted along the magnetic wave to the wireless charger and then transmitted to the electronic device through the wireless receiver. Instead of physically connecting each unit directly to each unit through a conductive wire or plug, electrostatic energy is sent to the battery through the air and the battery is charged.


Radio technology, or "Witricity," was developed by researchers at the Massachusetts Institute of Technology in 2007. However, being able to transmit power over the air is not a new technology. It was actually the scientific concept introduced by the inventor and electrical engineer Nikola Tesla in the early twentieth century. Due to the practical application of the science, recent developments and consumer demand for it, wireless charger capabilities are now becoming more likely.


Especially for consumers who want to implement hands-free operation through electronic or mobile devices, the influx of other wireless technologies, wireless chargers are becoming available to everyone. Now, companies that carry mobile devices also offer universal charger units that use wireless charger technology. For many consumers, this adds access to fully charged phones, personal data accessories and gaming devices.


It is worth noting that all wireless chargers do not power all devices equally efficiently. As radio technology is still in a new phase, some electronic devices will not accept the charge generated by the wireless charger, although it is called universal. In some cases, a wireless charger will enable a consumer to update their existing handheld device or purchase an adapter that can wirelessly transfer power to certain devices.


At most electronics retailers, wireless charger systems can be purchased for use by regular consumers. Because wireless chargers use less power to charge multiple devices, it is a convenient way to handle the power needs of a variety of consumer electronics products. In the future, wireless chargers can be used to power laptops, computer networks, and even deliver power to vehicles, homes and businesses without cables and wires.
