Understanding Reverse Wireless Charging Technology
Reverse wireless charging, also known as Wireless PowerShare, is a feature that allows a device to wirelessly charge other devices. This technology has been gaining popularity, especially among smartphone users. But how does it work, and what are the benefits of using reverse wireless charging?
How Reverse Wireless Charging Works
Reverse wireless charging uses the same principles as traditional wireless charging, but in reverse. Instead of receiving power from a charging pad, a device with reverse wireless charging capabilities can transmit power to another device. This is achieved through a process called electromagnetic induction, where an electromagnetic field is generated by the transmitting device and received by the receiving device.
The transmitting device, typically a smartphone, contains a coil that acts as a transmitter. When activated, this coil generates an electromagnetic field, which is then detected by a receiver coil in the receiving device. The receiver coil converts the electromagnetic field back into electrical energy, which is then used to charge the device.

Understanding the Technology Behind Reverse Wireless Charging
How it Works
Reverse wireless charging, also known as PowerShare or Wireless Power Bank, leverages the same principles as standard wireless charging. It involves the transfer of electrical energy between devices through electromagnetic fields. However, in reverse wireless charging, the charging device acts as the power source, while the receiving device becomes the recipient of the energy.
Typically, a charging coil within the power-source device generates an alternating magnetic field. A compatible receiving device, equipped with its own coil, picks up this magnetic field and converts it back into electrical energy to charge its battery.
Qi Standard and Compatibility
Most reverse wireless charging implementations adhere to the Qi (pronounced “chee”) wireless charging standard. Qi is a globally recognized open standard developed by the Wireless Power Consortium (WPC) that defines the technical specifications for both transmitting and receiving wireless power.
Compatibility is crucial. For reverse wireless charging to work, both the power-source device and the receiving device must support the Qi standard and have the necessary hardware components, including the charging coils.
Optimizing Reverse Wireless Charging Performance
Distance Matters
The efficiency of reverse wireless charging is directly influenced by the distance between the transmitting and receiving devices. Typically, the closer the devices are, the more efficient the power transfer.
Refer to your device’s user manual for the recommended charging distance. Exceeding this distance can significantly reduce charging speed and may even prevent charging altogether.
Alignment is Key
Proper alignment between the charging coils of the devices is essential for optimal performance.
Generally, the receiving device should be placed directly on the designated area of the power-source device. Some devices may have visual indicators or haptic feedback to guide the correct positioning.
Material Considerations
The materials used in both devices can affect the efficiency of reverse wireless charging.
Metallic objects or thick cases can interfere with the magnetic field, hindering the transfer of energy. It’s recommended to remove any metal objects or use a thin, non-metallic case for optimal performance.
Heat Dissipation
Reverse wireless charging can generate heat, especially when charging devices with larger batteries. Good heat dissipation is crucial to prevent overheating and potential damage to the devices.
Ensure adequate ventilation around the devices and avoid prolonged charging sessions at high power levels.
