Understanding Wireless Charging Technology
How Wireless Charging Works
Wireless charging, also known as inductive charging, relies on the principle of electromagnetic induction. It involves a transmitter coil within a charging pad and a receiver coil inside the compatible device. When you place your device on the charging pad, an alternating current flowing through the transmitter coil creates a magnetic field. This magnetic field induces a current in the receiver coil of your device, effectively transferring energy wirelessly.
Qi Standard and Compatibility
The Qi (pronounced “chee”) standard is the most widely adopted wireless charging standard globally. Devices certified with the Qi standard can be charged on any Qi-compatible charger. This ensures interoperability between devices from different manufacturers. The Galaxy A21, unfortunately, is not Qi certified, which means it does not support standard wireless charging.
Alternative Charging Solutions for the Galaxy A21
Wired Charging
While the Galaxy A21 lacks native wireless charging, it supports wired charging via a USB Type-C port. This provides a reliable and faster charging solution compared to wireless charging. Using the included charger or a compatible third-party charger, you can quickly power up your device.
