It will soon be possible to charge appliances using your smartphone's NFC chip. The Global NFC Forum just approved a standard that allows for wireless charging at 1W via the medium. It is meant for devices such as smartwatches, wireless earbuds, and fitness trackers that require low power.

Even though wireless charging tech has been around for a few years, we're only just beginning to see some significant improvements in it. OEMs such as Oppo, Vivo, and Huawei have been at the forefront of bringing it on par with cable-based charging. Phone makers have also made it possible for their users to power up other appliances with their smartphones. That, however, requires a wireless charger to be built into the device in question, further driving up manufacturing costs. It will soon be possible to eliminate that and charge accessories such as smartwatches and wireless earbuds via NFC.

NFC has a wide range of applications and can be used for everything ranging from data transfer to pairing hardware. The Global NFC Forum just approved a wireless charging specification that will allow users to charge their devices via NFC. For now, the maximum allowed wattage is capped out at 1W, but we can expect to see that number get higher as the tech matures. It will use 13.56 MHz base frequency and will allow for simultaneous charging and data transfer operations between the two devices.

It will be a while before we see the tech in action, though. Some new hardware will be in order, and a lot of kinks will need to be ironed out before it can make its way to commercial devices. Despite its 1W limitation, an NFC-based charging solution will allow a lot of companies to offer a functionality that was previously reserved only for high-end smartphones.

I've been an avid PC gamer since the age of 8. My passion for gaming eventually pushed me towards general tech, and I've been a stereotypical 'nerd' ever since. I have a degree in mechanical engineering and have worked in the manufacturing industry. When I'm not writing news on Notebookcheck, you can find me playing or watching an intense match of DOTA 2
