How does a wireless charging pad work?
A wireless charging pad works by creating an electromagnetic field, typically alternating current (AC), which safely sends power to a receiver in the device being charged. This receiver is usually a wireless charging coil that is built into the device.
The charging pad is connected either to a wall wart power supply that connects to an outlet or to a computer using a USB. The pad’s alternating current creates an alternating electromagnetic field that is detected by the receiving coil.
This then induces a current in the coil which is converted into direct current (DC) by the device’s built-in rectifier, which is then used to charge the device’s battery. This process works similarly to how an induction stove works, as the electromagnetic field created by the charging pad is used to induce a current in a loop of wire in the device being charged.
Because the process is contactless, it eliminates the need for cables and is much more convenient than plugging in your device.
Is wireless charging bad for battery?
Wireless charging is not necessarily bad for your battery in the long term, and in fact wireless charging has many benefits. One of the main benefits is that it is easier than plugging in a cable to charge your phone.

In terms of battery life, there is no clear evidence that wireless charging is bad for battery. In fact, most wireless chargers are designed with safety features to ensure the charger will stop charging if the battery becomes overheated.
There is also evidence that consistent use of wireless chargers can extend battery life. Despite this, it is generally recommended that people avoid leaving their phone charged all night to reduce strain on the battery.
Overall, while there is no clear consensus that wireless charging is bad for your battery, there are also no clear benefits in terms of battery life. Ultimately, it is up to individual users to decide if they are comfortable with the tradeoff between convenience and battery life when it comes to wireless charging.
How inefficient is wireless charging?
Wireless charging is not as efficient as direct wired charging. It is estimated that wireless charging typically as low as 70-80% of the energy transferred being delivered to the device while its more efficient counterpart, wired charging, can reach up to 98-99%.
This means that a device being charged by a wireless charger will take longer to charge than the same device being charged through a wired connection, even if the wattage of both chargers is the same.
Moreover, wireless chargers can be less efficient if the device or the charger itself is deformed or covered in dust, or if the device or charger is placed too far away from each other. As a result, these inefficiencies can further reduce the efficiency of the wireless charging.
Although wireless charging is not as efficient as direct wired charging, it is more convenient as it eliminates the need to fuss around with cables, which may be a worthwhile trade off in some cases.
Can laptops be wirelessly charged?
Yes, it is possible to wirelessly charge laptops with the right technology. Wireless charging, also known as inductive charging, involves using an electromagnetic field to transfer energy between two objects.
