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 air 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 do not 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 do not 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 original device retains its 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 aspects
and dimension 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.
