Soon, you may be able to buy one smartphone which will be able to charge small Appliancessuch as headphones or smartwatches. It NFC Forum, responsible for technology near-field communications (NFC), present the Wireless Charging Specification (Wireless Charging Specification-WLC). This feature will allow devices equipped with an antenna (eg chargers or smartphones) to carry power up to one watt in compatible Appliances. At the same time, NFC devices equipped with the feature will be able to communicate with each other.
It may seem a little, but one watt is enough to charge a smartwatch or wireless headphones, relatively quickly. And since most smartphones have NFC technology, manufacturers can easily apply this type of reverse charge. This way, small devices can be easily charged without the need for cables.
Η AppleThe Sony and Google are sponsors of the NFC Forum, h Samsung is a key member and Huawei cooperating member. Apple reportedly planned to introduce a feature "Bilateral charging" for iPhone 11 that could work with AirPods headphones, but that didn't happen (yet). If it introduces such a feature, it will probably work with Qi, so that there is compatibility with them AirPods and Watch.
On the other hand, Samsung introduced a form of this technology called Wireless Powershare (based on Qi charging standard) for Galaxy S10 and Galaxy Buds headphones. Η Huawei presented a similar feature in Mate 20 Pro. However, none of these devices use NFC directly for charging. The new WLC standard can improve compatibility between devices from different manufacturers, while allowing easier charging for Internet of things devices. However, the feature has now been introduced and we do not know exactly when it will be implemented.
