The world of wireless charging has revolutionized the way we keep our devices powered up. No more tangled cords, lost charging cables, or damaged ports. But, with the advent of wireless charging, a new question arises: do wireless phone chargers work through cases? In this article, we’ll dive into the world of wireless charging, explore the technology behind it, and determine whether wireless phone chargers can indeed work through cases.
Understanding Wireless Charging
Wireless charging, also known as inductive charging, uses an electromagnetic field to transfer energy between two devices: a transmitter (the charging base) and a receiver (the device to be charged). The transmitter contains a coil that generates an alternating magnetic field when an electric current passes through it. The receiver, embedded in the device, contains a coil that converts the magnetic field back into an electric current, which is then used to charge the device’s battery.
Wi-Charge, a company specializing in long-range wireless charging, explains that wireless charging operates on the principle of electromagnetic induction. “When you bring the receiver close to the transmitter, the magnetic field induces an electromotive force (EMF) in the receiver coil, which in turn generates an electric current.”
Qi (Chee) Wireless Charging Standard
The Qi (pronounced “chee”) wireless charging standard is the most widely adopted and recognized wireless charging protocol. Developed by the Wireless Power Consortium, Qi is designed to ensure compatibility and interoperability between devices and charging pads. Qi-enabled devices and charging pads communicate with each other to negotiate the optimal power transfer.
Qi has three main components:
- The transmitter (charging base): Contains the coil that generates the electromagnetic field.
- The receiver (device to be charged): Contains the coil that converts the magnetic field back into an electric current.
- The power transmitter unit (PTU): Manages the power transfer and ensures safe and efficient charging.
Do Wireless Phone Chargers Work Through Cases?
