The word “Qi” (pronounced like “Chi”), which means “life energy” in Chinese, is thought to provide every living being with the required amount of vital force.
The Qi standard is also based on this principle, because it proposes that battery-powered electrical devices, such as smartphones or electric toothbrushes, can be charged through contactless power transmission.
All components that are manufactured according to this standard can use the technology to communicate with each other and to charge themselves. It does not matter which manufacturer produced the device. This gives you, the customer, the best possible range of choice of chargers for your electrical devices.
Whether at home, in the car or in the office, if you have a Qi charger, then it is a piece of cake to charge your Qi-compatible smartphone, for example. This means that you could charge your smartphone using an IKEA charging station at home and an INBAY station in your car. And you can do it all without charging cables!
The international Qi standard specifies a charging voltage of 5V at a current of 1A.This corresponds to the charging capacity of commonly used wired chargers. Therefore, it is completely sufficient for charging a Qi-compatible smartphone.
