The inception of wireless chargers excludes the hassle of untangling wires, adding to the user’s convenience. The revolutionary technology was introduced in 2010 and was initially limited to high-end phones only. However, over the course of time, it has become a must-have smartphone accessory. Getting on the bandwagon, all the leading mobile phone brands offer wireless phone chargers with almost all the latest model ranges.
Let’s dive a little deeper into the world of wireless chargers and elaborate on what they bring to the table for the users.
How Wireless Charger Works?
The principle used in working on wireless chargers is similar to that of Nikola Tesla’s resonant-inductive coupling process. The charger has an electromagnetic coil that creates a magnetic field, transferring charge to the phone.
When a charger is plugged in, the transmitter coil in the charging base sends a signal to the receiver coil and starts electromagnetic induction. The electrons inside the transmission coil start flowing and create a magnetic field.
Similarly, the electrons inside receiver coils start flowing around the magnetic field, making the flow of electricity possible and charging the phone.
Types of Wireless Chargers
The following are the most common types of wireless phone chargers.
Inductive Charger
Inductive chargers are one of the most common types of wireless chargers. It uses an electromagnetic field to transfer electricity between the charger and the phone. The Qi Wireless charging is also based on the inductive charging principle.
Resonant Charger
The working principle of resonant chargers is similar to inductive chargers. However, it uses a resonator for energy transfer which increases the transfer range. Therefore, resonant charger users are exempted from placing their phones exactly on the charger. Speaking of range, here are some best wireless chargers in 2023 with exceptional range and power output.
Radio Frequency Charger
As evident from the name, the Radio Frequency (RF) chargers use radio waves to charge the devices. A transmitter sends radio waves, and a receiver converts these waves into electrical energy.
