How Wireless Mobile Chargers Work ?

By:Prayag nao




The availability of wireless charging options has brought up a common question: How does it work? Here’s how to determine if you can use a wireless charger to power up your smartphone.

How does wireless charging work?

Wireless charging, also known as inductive charging, is a convenient and fuss-free way to power up your smartphone. Wireless chargers emit an alternating magnetic field via a transmitter coil, which then induces a voltage in the receiver coil found in the device. wireless charging pads are capable of charging smartphones, tablets, Bluetooth headsets, cameras and portable power packs.

Most wireless mobile charging solutions rely on inductive coupling. Here's a typical approach:
The charging station takes the form of a mat or other flat surface. Inside the mat are one or more inductive coupling coils. The mat itself is wired -- you have to plug it into a wall socket. Since the electricity coming to your house is alternating current, the mat provides the electricity the coils need to generate a changing magnetic field.
Your mobile devices need a special case or attachment to take advantage of this magnetic field. Some manufacturers make devices with cases and electronics that facilitate inductive coupling -- the Palm Pre had this feature. But most manufacturers make equipment that still requires cables or wires to recharge. For these devices, you may need to use special sleeves -- each sleeve fits a particular model of a device. Or you may have to attach an adapter that plugs into your mobile device's charging port. The sleeve or adapter will have the matching coil to the surface's inductor coils.



wireless Charging Advantages


  • Environmentally-friendly


The growing use of wireless charging technologies reduces CO2 emissions by hundreds of tons each year by eliminating disposable batteries and cords. Your use of a wireless charging device will be contributing to a more sustainable environment by helping to reduce world waste.

  • Convenience


Wireless charging methods eliminate messy cords, providing a more convenient charging experience. Humavox Radio Frequency (RF) technology makes it even easier to use because it allows for non-contact wireless charging, meaning you can move and use your device while it is being charged.

  • Multi-usage

Although most wireless charging systems don't allow multiple devices to charge simultaneously , everyone in today's electronic world has at least two to three devices that need to be charged daily. In our mobile world, this option can become really handy.

There are numerous benefits to wireless charging. However, perfection does not exist and wireless charging also has its disadvantages.

Disadvantages of Wireless Charging Systems


  • Low performance, extra heating


These are the problems that most devices on the market are dealing with. Today's wireless chargers just can't reach the same level of efficiency as traditional USB charging, so the charging process is slower. Also, the heat generated in wireless charging is higher in comparison with the conventional way of charging.

  • Mobility


Though the charging between your smartphone and the charging station is wireless, it is still necessary to plug the charging pad to the wall. Therefore, the devices currently available in the market are not really portable and can't allow you to use your smartphone while charging.
