Over the past few months, almost all the phone manufacturers came up with new phones with various features. Among those brand new features released, one of the most significant features is the reverse wireless charging. Many phones adopted the wireless charging feature sometime back. Samsung phone series starting from Galaxy S6, and iphone 8, iPhone 8 plus, iPhone X… All these phones had the wireless charging feature, which means they had the ability to be charged wirelessly.
But none of them had REVERSE WIRELESS CHARGING feature. However, recently, a number of phones were released with this amazing feature.
What exactly is reverse wireless charging?
Reverse wireless charging means the capability of the phone to act as the charging station and be used to charge another wireless device. The other device could be a another phone, a tablet, or even a headphone, which has the wireless charging ability. The phone that acts as the charging station will transfer energy to the receiving device via electromagnetic induction.
What are the phones that offer reverse wireless charging?
This feature was first offered by Huawei. Later on few more Samsung phones also came up with this feature.
- Huawei Mate 20 Pro : This was the first ever phone to be released with the reverse wireless charging feature.
- Samsung Galaxy S10 / S10+ / S10e : Samsung offered this feature with all three models in its S10 range. Significance is that since Galaxy buds come with wireless charging ability, users can directly charge their headphones using their S10 range phones.
Huawei P30 Pro is the next Huawei phone that will come with reverse wireless charging. It is predicted that the next iPhone will also carry this feature.
What are the phones that can be charged through reverse wireless charging?
Any device adhering to the Qi standard (an open interface standard that defines wireless power transfer) can be charged through reverse wireless charging, irrelevant of the brand. Only thing is the feature should be set active, should be within the detectable area and the two devices should be paired back-to-back.
What about the charging speed through reverse wireless charging?
This method is obviously very slower than charging using a cable. It will take around 120 minutes to charge a 3000mAh battery. Also the source device will have a limit on how much energy it can output from its battery before that depletes.
Of course, reverse wireless charging has quite a few draw backs with regard to charging speed and charging capacity. But still this is a feature that can be found useful with emergency situations. At the same time, this feature reduces the number of devices that should be plugged in one place for charging purposes. Reverse wireless charging is still not that much popular with phones. In the future, it might come to users with much more advancements! Who knows what? Let’s wait and see!
