Wireless charging is a ground breaking technology that lets you charge your devices without mingling with cables or faulty USB ports. Simply put your phone on a wireless charging surface and all will be taken care of. That comes with a negative element - while charging you can not use your phone.
Si-Ware Systems and Ossia have come up with a new system called Cota which can be used to charge compatible phones within a 30 foot radius. While devices can consume a maximum of 6 watts for charging, this system is capable of transferring 10 watts power. This is nowhere near the Quick Charge 2.0, but it does a pretty decent job considering all the factors. Thanks to the radio frequency technology - the device charging won't be affected negatively in case of minor obstructions.
This technology doesn't only apply to smartphone and wearable devices. Things like wireless keyboards can also be charged via this system without plugging in anything. The device will be charged till the time you are near the charger.
Although the effect of constantly charging the devices for 12 hours in day is yet to be found out, we all can agree that this is indeed a great step forward.
