Portable cellular devices have become a staple for the majority of people. They keep us connected to the rest of the world 24/7. The entire idea behind using cellular devices was to go cordless, but we were (and still are) stuck with pesky cables for charging and syncing our data.
Lately, wireless charging, also known as inductive charging, has been making a big splash in the tech world. While it’s more popular with charging cell phones, wireless charging has actually been around for a while – such as being used for charging wireless toothbrushes.
Due to wireless charging’s low efficiency, however, companies had to develop the process further in order for devices like cell phones or tablets to sustain a charge for longer use.
What is Wireless Charging?
Wireless charging, or wireless power transfer, is the process in which energy is safely transferred from a device used to transmit power to another device that is made to receive it.
Wireless charging is performed without the use of any wires or cables from the transmitting device to the receiving device, which is how it gets its name.
The energy that is transferred between the devices is used to either charge or recharge the receiving device’s battery. Charging your device wirelessly, at least in more modern times, has been proven to be just as efficient as charging your device through a cable.
How Does Wireless Charging Work?
Your charging station acts as the transmitting device. This is where the magnetic energy is made and is waiting to be transferred to a receiving device.
Compatible portable devices have two coils in them that are used to receive the magnetic current from the charging station, and then turn the magnetic current into an electric current to charge its battery.
Once you lay your compatible device down onto the charging station, the station uses an alternating magnetic field to begin transferring a current to your transmitter coil inside your portable device.
If both of the coils in the portable device are within the required distance, the magnetic moves from the transmitter coil to the receiver coil within the device. The receiver coil then begins transforming the magnetic current into an electric current.
The device’s receiver coil takes the new electric current and becomes a direct current (DC) for the device, thus charging the battery.
Is My Device Compatible?
Wireless manufacturers, like Samsung and Motorola, are among the better-known companies to include wireless charging capabilities within some of their devices.
Many other manufacturers are getting into the groove of wireless charging, slowly but surely. For those of us with devices that aren’t compatible, but we absolutely need to experience a completely wireless device, there’s hope.
If you don’t have a compatible device, companies like Qi are developing accessories to help.
Wireless charging is continuously being further researched and developed to harness its true power and discover more about the process. As we see more manufacturers begin to incorporate wireless charging in their devices, it’s no doubt the process is becoming more mainstream.
