Wireless Charging Technology
Even though wireless charging technology may seem a relatively new phenomenon, anyone who owns an electrical toothbrush has been using the technology for many years. Your sonic toothbrush is fed with wireless power when placed on the charging dock. Nowadays over 600 types of mobile devices on the market can be charged wirelessly.
As a wireless charging expert, we’d like to explain more about the transfer of wireless power and its technology. How does wireless charging work? Does your phone support wireless charging? What is this Qi standard? Is wireless charging safe?
Wireless charging technology – inductive power transfer
Qi wireless charging technology uses an electromagnetic field and inductive coupling to send energy from point A (transmitter) to B (receiver).
Qi chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station. A second coil in a mobile device takes energy from this electromagnetic field and converts it back into electrical current to charge the battery. Any compatible mobile device up to 15W can be (re)charged this way. Learn more about inductive charging
Most Zens chargers are equipped with one big charging coil, to ensure flawless wireless charging every time the device is used. Thanks to the large number, the device(s) can be freely placed on the charging pad and 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 charging sweet spot. How Qi charging works
Wireless charging technology – the Qi standard
The Qi (pronounced chee) standard was developed in 2010 by the Wireless Power Consortium in which over 320 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. A vastly growing number of devices such as smartphones, cameras, speakers and wearables have Qi technology incorporated as a standard. All Qi receivers will work with all Qi transmitters, meaning that all enabled devices are compatible.
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.
Large charging sweet spot: 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 wireless charging technology.
- To charge your smartphone, you need a wireless charger. Position it in a convenient location – for instance on your desk.
- Next, simply place the smartphone on top of the wireless charger and ‘get charging’.
- On both your smartphone and the charging pad a LED indicator shows when your phone is charging.
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 wireless charging case with Qi integrated.
- Mount the Qi wireless charging case to your smartphone.
- Position your charger in a convenient location – for instance on your desk.
- Next, simply place the smartphone on top of the charging pad and ‘get charging’. A LED indicator shows when charging has commenced.
