Samsung flagship phones support wireless charging for good few years now, yet the company has never decided to make wireless charger of its own. Until now, that is - Samsung-made wireless charger patent has just surfaced online. Device is described as using QI standard and able to work in both induction and resonant modes, with possibility of switching between one and another. Picture above shows that the device can charge, for example, both a smartphone and a smartwatch at the same time.
Of course it is just a patent. I doubt Samsung has a working, market-ready unit on its hands, and it may be months before the company decides to sell it, if at all. Then again, near reveal of Samsung S9 and S9+ would be a good opportunity to reveal the charger as well.
