WIRELESS POWER
QI - THE STANDARD FOR WIRELESS CHARGING
Wireless power isn’t a new concept. The idea was conceived in the late 1800s when the visionary scientist and engineer Nikola Tesla began powering lights remotely. The same principles have led to Qi, the global standard for charging mobile devices through wireless power transmission.
Qi allows product developers and manufacturers to change the way that people and devices interact with power and data. It dynamically seeks resonance and optimizes power transfer under multiple, varying load conditions and spatial configurations. It can be utilized essentially anywhere traditional power needs exist. It is a revolutionary advancement unleashing a new world of creative options – power and data can be efficiently transmitted to virtually any electrical device without the constraints of plugs, power cords and chargers.
Simple and safe, Qi charges or powers an array of devices, from smartphones to cordless kitchen appliances. The technology combines the benefits of both induction and resonant charging to deliver a versatile standard that offers a full range of innovative features and capabilities.
NO MORE CORDS

Wireless power enables designers and manufacturers to cut the final cord and give consumers what they’ve been asking for – a truly wireless lifestyle. Through the Qi standard, power, data and communications now flow across devices from different manufacturers ensuring a seamless user experience.
EXTENDED PRODUCT LIFE
_______________________
Wireless power eliminates the need for external ports. Devices can now be designed to eliminate the wear and tear on connectors and cables that comes with repeated use. They can also be completely sealed to protect them while operating in unforgiving environments, including under water and in extreme temperatures.
UNIVERSAL COMPATABILITY
_______________________
Any product that requires power can utilize wireless power technology. It applies to everything from consumer electronics like phones and tablets to kitchen appliances, medical devices and beyond. And with the Qi standard driving development, multiple devices from different manufacturers can now be supported by a single source, making easy, efficient charging simple.
A GROWING INDUSTRY

HOW WIRELESS POWER WORKS
Wireless power transfer was first demonstrated in the late 1800s, but it is only in the last decade that the technology has been perfected to the point where it offers tangible benefits to real world applications.
Wireless power is commonly known by many terms, including inductive power transfer (IPT), inductive coupling, resonant wireless power and resonant power transfer. Each of these terms essentially describe the same fundamental process – the wireless transmission of electricity or energy from a power source to an electrical load, without connectors, across an air gap. The basis of a wireless power system involves essentially two coils – a transmitter sending energy to a receiver coil via an oscillating magnetic field. The transmitter coil is energized by alternating current to generate a magnetic field, which in turn induces a current in the receiver coil.
