Wireless charging is a relative new technology that is rapidly making it’s way to our daily lives. You may have been using wireless charging for many years already if you possess an electrical toothbrush: you just put it on the holder and it starts charging. Nowadays already over 500 types of devices, including smartphones, are in the market which can be charged wirelessly.

As a wireless charging expert, we’d like to explain more about the transfer of wireless power and it’s technology. How does wireless charging work? Does your phone support wireless charging? What is this Qi standard? Is wireless charging safe?

Wireless charging by induction

The ZENS chargers use an electromagnetic field and inductive coupling to send energy to the device to be charged. They are suitable to charge any compatible electronic device up to 5W. The energy transmitted is stored in the device’s batteries.

The chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station. A second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. Learn more about inductive charging.

How wireless charging works Wireless charging technology: induction coils

Most ZENS chargers are equipped with seven inductor coils, to ensure flawless wireless charging every time the device is used. Thanks to the large number of embedded coils, the device(s) to be charged can be freely placed on the charging pad and they don’t have to be locked into position. Inductive charging makes charging mobile devices more convenient; rather than having to connect a power cable, the unit can be placed on or close to a charge plate. Learn more on how wireless charging works.

The Qi standard

The Qi (pronounced chee) standard was developed in 2010 by the Wireless Power Consortium in which over 220 companies (including Philips, Sanyo, Panasonic, Nokia, Samsung, Sony Ericsson, LG, HTC and Motorola) participate. Qi is the sign of interoperability between power transmitters and power receivers. In the near future, devices such as smartphones, cameras and MP3 players will incorporate Qi technology. All Qi receivers will work with all Qi transmitters, this means that all these devices can be charged with ZENS wireless chargers.

Qi is derived from Asian philosophy. It means ‘vital energy’, an intangible flow of power. When this logo is on your portable device, it  can be charged with any ZENS Wireless Charger.

Free positioning

The free positioning feature of the ZENS chargers allow for ultimate user comfort. Thanks to no less than seven induction coils in the wireless charging pad, the device doesn’t have to be locked into an exact position. The user is ensured that, when he or she places the phone on the pad, its battery will be charged successfully.

 

How does wireless charging work with Qi integrated?

  • Firstly, check to see if your smartphone supports the Qi technology.
  • To charge your smartphone you need a wireless charger. Position your charging it in a convenient location – for instance on your desk.

How does wireless charging work with a Qi add-on?

To charge your smartphone you need a wireless charger AND a designated Qi add-on, mostly a Qi case OR flip case with Qi integrated.

  • Mount the Qi add-on to your smartphone.
  • Position your charging pad in a convenient location – for instance on your desk.
  • Next, simply place the smartphone WITH Qi add-on on top of the charging pad and ‘get charging’. A LED indicator shows when your phone is charging.
