Wireless charging range refers to the maximum distance between a wireless charging device (transmitter) and a compatible device (receiver) that allows for successful charging. This range can vary depending on factors like the charging technology used, the power output, and the materials surrounding the devices.
How does wireless charging work?
Wireless charging relies on the principle of electromagnetic induction. The transmitter emits an electromagnetic field when powered on. This field induces an electrical current in the receiver coil within the compatible device, converting the electromagnetic energy into electrical energy to charge the device’s battery.
Why should I increase my wireless charging range?
Increasing the wireless charging range offers several benefits. It provides more flexibility in placing your device for charging, eliminating the need to precisely align it with a charging pad. This is particularly useful for larger devices like laptops or tablets, where precise alignment can be challenging. A longer range also allows for charging through protective cases, as long as the case doesn’t significantly interfere with the electromagnetic field.
How do I increase the wireless charging range of my device?
Unfortunately, there isn’t a foolproof way to drastically increase the range of your device’s built-in wireless charging. The range is largely determined by the hardware and software specifications of your device and charging pad. However, you can try a few things:
– Ensure there are no metallic objects or thick materials between your device and the charging pad, as these can interfere with the electromagnetic field.
– Position your device directly above the charging pad’s center.
– Consider using a charging pad with a higher power output, as this can sometimes extend the range slightly.
What if my wireless charging range is still too short?
If the range remains insufficient, you might need to explore alternative solutions:
