What’s the current power level of the Qi standard?
In 2011, the Wireless Power Consortium began to extend the Qi specification to medium power. As of 2019, the Medium Power standard currently delivers 30 to 65 W, it is expected to eventually support up to 200 W (typically used for portable power tools, robotic vacuum cleaners, drones and e-bikes).
