What is Reverse Wireless Charging

Reverse wireless charging isn’t any different from standard wireless charging. Except that you are using your phone as the wireless charging pad.

Wireless chargingis the ability to charge your device without plugging any wires or cables into its ports. Instead, you can use a wireless charging pad to transfer power through electromagnetic induction. The technology that enables us to do it is calledQi charging. The same physics is also involved in reverse charging.

How Does Reverse Wireless Charging Work

The phone with reverse wireless charging has a coil that carries Alternating Current. This current generates a magnetic field around the same. The device that you want to charge wirelessly also has a similar coil.

When you bring the two coils in contact, the magnetic field from the coils in the wireless charger (phone with reverse wireless charging) will induce an electric current in the device’s coil that wants to charge wirelessly – this coil is connected to a battery to which the current flows and hence, is recharged.

Using reverse wireless charging, you can charge a phone, tablet, Bluetooth earphones, and any device that supports wireless charging. However, the intent behind reverse wireless charging is that you can turn your device into a power source under dire circumstances.

Since your phone only has a limited amount of power, it’s ideal to transfer the same to another device using reverse wireless charging only for a quick battery boost. It is best suited for charging your wireless accessories.

How Fast Is Reverse Wireless Charging

There is a lot of debate as to whether reverse wireless charging is an effective feature or another gimmick to boost sales. Some might argue that it is indeed a gimmick because it isn’t fast enough in comparison to using a power source from a wall outlet.

Well, it isn’t fast enough, but it also isn’t a fair comparison. Reverse wireless charging is in no way meant as a replacement or even as an alternative to using wireless charging on awall power outlet.

To answer the question – reverse wireless charging speeds are around 4.5W to 5W on most devices. However, newer devices support reverse wireless charging up to 10W. Yet, it is barely enough to charge a phone quickly.

Enable Reverse Wireless Charging on Your Android Smartphones

Here are the instructions to enable reverse wireless charging on your Android device. Most flagship Android devices support reverse wireless charging. You can find it in the Settings app – if not, then your device doesn’t support it.

We’ve used a OnePlus device to demonstrate the process. However, the steps remain the same for other Android devices too.

OpenSettings > Battery > Reverse wireless chargingand turn it on.

There’s also an option to automatically disable reverse wireless charging if the battery level drops below a certain level. However, the minimum amount of battery percentage required to charge another device wirelessly stands at 25%. This minimum requirement can vary according to different devices.
