About A Wireless Charger

A wireless charger is a device that makes it possible for you to charge your phone or tablet without a physical connection. Wireless charging is based on the principle of magnetic resonance. Here electricity is transferred between the two objects through coils. The process starts when the main voltage is converted to high frequency alternating current (AC). The AC is then transmitted to the transmitter coil via the transmitter circuit.

When the AC reaches the transmitter coil it induces a time varying magnetic field which extends to the receiver coil of your device. The current flowing within the receiver coil is converted to direct current (DC) by the receiver circuit and it’s used to charge your battery.

Pros of a Wireless Charger

There are a number of advantages that come with wireless chargers. One of the main advantages is that you don’t have to go through the hassle of inserting your USB cable to your device every time you want to charge your phone or tablet.

Since you don’t have to connect your device to the USB socket, you can cover it thus saving the general wear and tear of the hardware. This ensures that your device retains its original good looks for a long time.

How to Buy a Wireless Charger

For you to buy the right charger you need to consider a number of factors such as:

Device compatibility: most of the chargers in the market not only charge the specified mobile phones, they also charge other devices. For example, a Choetech charger can charge a Nexus phone. Before making your purchase you should ensure that the charger that you are buying is compatible with your device. For ideal results you should consider the technical and dimension aspects when determining the compatibility of the devices.

Your needs: There are some chargers that come with backup batteries and others with Bluetooth speakers. If you travel a lot you should go for a charger with backup batteries; however, if you love listening to music you should go for a charger with Bluetooth speakers.

Durability: who likes a device that will last for only a short period of time? To avoid wasting a lot of money on the chargers you should go for a device that is sleek, sturdy and can withstand accidental falls.

Conclusion

This is what you need to know about wireless chargers. For the devices to last for a long time you should buy them from a reputable store.
