We've all been there. You're at your friend's house, and your phone is on its last leg. You scrounge around for a charging cord, but come up empty. Your friend looks at you sympathetically and says, "Don't worry, I've got a wireless charger." You're sceptical but desperate, so you give it a go. We all know the convenience of wireless charging—no more fumbling around for cords—but is it safe?
Wireless Charging: How Safe Is It?
Wireless charging is a new technology that is becoming increasingly popular. It allows you to charge your devices without having to use cords or plugs. However, there is some debate about whether or not this new technology is safe. First, it helps to know the three main types of wireless charging technology: inductive charging, resonance charging, and radio charging.
What is Inductive Charging?
Inductive charging is a type of wireless charging that uses an electromagnetic field to transfer energy between two devices. This is the most common type of wireless charging, and it is used in many devices, including smartphones, tablets, and laptops.
Inductive charging is typically used for devices that are not in use, such as when your phone is sitting on a wireless charging pad. When the device is in use, it can be more challenging to transfer energy inductively, so other methods, such as radio charging, are used.
What is Radio Charging?
Radio charging is a method of wirelessly transferring energy that uses radio waves to transfer energy between a power source and a device. This method is typically used for devices that are in use, as it can be more difficult to transfer energy inductively when the device is not in use. Radio charging is typically more efficient than inductive charging and can be used to charge devices at a distance.
What is Resonance Charging?
Resonance charging is a new type of wireless charging technology that uses resonant inductive coupling to transfer energy between two devices. This means that it can charge devices at a distance without the need for direct contact.
How Safe are Wireless Chargers?
Wireless chargers are safe to use and pose no risks to your devices. They emit low levels of electromagnetic radiation (EMR), a type of non-ionizing radiation, which means it does not have enough energy to cause cancer.
One thing to keep in mind, however, is that wireless chargers can get hot just like any other type of charger. This is because the charger converts electrical energy into electromagnetic energy, and some of this energy is lost as heat.
So, if you notice that your wireless charger is getting hot, it is not a cause for concern. Not to mention, many wireless chargers are made with built-in safety protocols that prevent them from overheating.
Is it Safe to Leave Your Phone Charging on a Wireless Charger Overnight?
It is safe to leave your phone charging on a wireless charger overnight. Wireless chargers are designed to safely trickle charge your battery once your phone reaches 100 per cent, so you don't have to worry about overcharging.
The Bottom Line: All About Wireless Charging
Wireless charging: is it safe and effective? This is a question that many people have been asking lately. With the release of the iPhone 8, iPhone X, and various other devices that support wireless charging, the question is more relevant than ever.
Ultimately, wireless charging is safe, efficient, and easy to use. If you're looking for a convenient way to charge your devices, then wireless charging is the way to go.
