Hazards of wireless charging

As you’ve seen in our previous blogs, most of them include the promotion of technology and the discussion of how it has advanced in the previous years.

Our blogs mostly define the changes technology has made, in an optimistic way. But this particular blog is about a tech which has been available for quite some time but still hasn’t lived up to the hype even after advancing over the years.

Yes, we are certainly talking about wireless charging materials. Even if they are becoming quite popular and worked upon hard, no such tech has provided us with a perfect version of the.

What are they?

Obviously, the name gives it all away. Chargers without wires. These portable chargers help charge electronic tech batteries, they can be carried anywhere and everywhere.

Older wireless chargers were used by attaching mobile phone batteries to them, new advancements include placing smartphones on them.

There was also one wireless charger which involved placing smartphones in light to charge them through solar radiations. These chargers vary incompatibility from smaller to larger devices.

Types of Wireless Chargers

There are three types of wireless charging; Radio, Inductive and Resonance.

Radio Charging

These chargers are designed to charge small battery devices like wireless keyboard, mouse, smartphones, etc. Wireless radio charging involves a transmitter that is connected to a socket in order to generate radio waves.

When your device receiver is configured to the same frequency as the radio transmitter, you can charge your device battery.

Inductive Charging

Inductive charging is used for medium-sized devices such as a few different types of smartphones, tablets, and MP3 players. When this method is used for wireless charging, an adapter that contains contact points is attached to the back of your device.

When your device battery requires charging, you simply place it on a wireless or conductive charging pad. The charging pad is then plugged into an electrical outlet.

Resonance charging is a different type of wireless charging that is used for devices that utilize a significant amount of power. These are devices such as a large computer, electric car, vacuum cleaner, or robot.

Resonance charging involves a copper coil which is attached to the device that requires charging with another copper coil attached to a power source.

Wireless charging takes place when both copper coils are configured to a common electromagnetic frequency. This allows you to charge the device battery from the power source. Wireless resonance charging is accomplished over short distances only.

What are the Hazards? Disadvantages of Wireless Charging?

One of the most harmful hazards to look out for regarding wireless charging is the electromagnetic radiations they generate. High levels of electromagnetic radiations impose different types of risks such as anxiety, depression, etc.

Its disadvantages include


  • Harmful Radiations
  • Phones can’t be removed whilst charging.
  •  Overheating of devices
  •  Slow

Some people say wireless charging would be the future. But that’s what it actually is, “The Future”, not the present. Until now, wireless charging doesn’t show any promise but if improvements are made it would be one of technological advancement.
