All the cool kids are including Wireless Charging in their devices these days. Primarily in the upper tiers, and a limited set of those devices support reverse wireless charging. Of all the protocols, the NFC standard has been updated by the NFC Fourm to include some wireless charging capacity.

For those of you hoping to start using Qi pads on your existing NFC capable phones, sorry… no such luck! There are a number of reasons for this, ultimately there are technical limitations to the NFC antenna. But not so much that it can’t produce some wireless charging output.

Board of Directors approved and adopted the Wireless Charging Specification (WLC) that makes it possible to wirelessly charge small, battery-powered consumer and IoT devices with a smartphone or other NFC charging device at a power transfer rate of up to one watt.

The key there is up to one Watt, that’s a pretty low output for current wireless charging standards. In reality, that’s barely enough output to slow the battery depleting on a current smartphone and many may not even register the input. Where this could be extremely useful is the capability to charge small devices like earphones neglected for a few days.

How widely this feature will be used is yet to be seen. The continual development of the communication platform and additional features means we’ll continue to have new and increasingly easier ways to communicate and interact with the world around us.
