How fast is reverse wireless charging of the upcoming iPhone11 series?
A new leak from Tipster Ben Geskin shows that the upcoming iPhone new series will have logo on the center of the back, and an “iPhone” will not be there at all. It appears that this change is in order to keep in pace with other lines of Apple because both iPads and Macbooks have always had the logo centered. But Geskin points out that it is designed especially for reverse wireless charging — the center of iPhone is exactly where devices like Airpods should be put to be wirelessly charged, and having logo on that place makes it easy to locate the charging spot.
So what is reverse wireless charging? It is a technology that turns the phone into a charging station for other Qi-supported devices. Ever before Apple, Huawei and Samsung have both applied this technology on their phones. Huawei Mate20 Pro, Huawei P30 Pro, Samsung Galaxy S10/S10+/S10e/5G, Samsung Note10/Note10+ all support reverse wireless charging. Though in its infancy, reverse wireless charging is expected to be utilized by more manufacturers in the future.
What is the difference between wireless charging and reverse wireless charging?
Well, they are the same basically. Both are aimed at wirelessly charging for any Qi-compatible devices, though there’s no limit of power offer for a wireless charging pad or stand while the amount of power output of reverse wireless charging is strictly restricted within the battery capacity.
Which device is compatible with reverse wireless charging?
There’s no limit on which device to charge, not matter it is your smartphone, headphone, mouse etc., as long as it is compatible with Qi wireless charging standard.
How fast is reverse wireless charging?
If you count on the phone with this technology to charge your wireless headphone or any other wireless accessories, then you may get upset. Now that reverse wireless charging still has no power standards, and reports have shown that the Mate 20 Pro delivers up to 2.5W to 3W of output, and the Galaxy S10 up to 4W wirelessly in reverse. These are really low speed, much less than 10W, a figure most wireless chargers on the market own, not to mention 50W Super VOOC from OPPO Find X Lamborghini Edition. But for emergent cases or backup power solution, say, your iWatch needs charging or your friend’s phone drains to only 5% of battery, a reverse wireless charging supported phone is of great help.
