A wireless charger is a device that can charge your phone wirelessly by using electromagnetic induction. There are many different types of wireless chargers – some use induction without any plug, others use a plug for the coil. 

A wireless charger is a device that allows you to charge your phone or other device without having to connect it to a cable. It works by using electromagnetic waves to transfer energy from the transmitter to the receiver. You can visit https://www.kewlabstech.com/ to buy a wireless charger.

There are two main types of wireless chargers: induction and resonance. Induction chargers use a wire to send an electric current between the transmitter and receiver. This current creates an electromagnetic field that anchors the device to the charger. Resonance chargers use sonic waves instead of electric currents. They generate vibrations that match the frequency of the electric field in the transmitter. This causes the receiver to vibrate, and absorb energy from the transmitter.

There are a number of benefits to using wireless chargers, including the following:

1. They're easy to use – Just place your device on the charger and it will start charging.

2. You can charge multiple devices at once – If you have multiple devices that need to be charged, you can use the same charger to charge all of them simultaneously.

Wireless chargers are becoming more popular because they're more convenient than traditional chargers. You can use them anywhere there is an outlet, and they don't require any installation.
