However, before buying, you must always check the compatibility between the charger and the phone you have.

How does a wireless charger work?

In electromagnetic induction (discovered in 1831 by Michael Faraday) electrical energy is created by passing a magnet in a coil of copper wires. This phenomenon is used today in a wide range of applications including transformers, electric motors, generators and, indeed, wireless accumulators. A wireless charger uses two coils of conductive material: the charging station contains an inductor that generates an oscillating magnetic field and a transmitter that transfers energy; in turn, the receiving device through its coil produces the electrical energy that is stored in its accumulator. Due to the nature of the magnetic induction that tends to disperse, the charger and the phone must be very close to each other. The smartphone must be placed on the charger's base which in turn must be connected to an energy source in order to function. The strength of a cordless portable USB charger depends on the number of coils that can be twisted around the magnet and the power of the magnet itself. The charging cycle takes place as in normal batteries, the device is immediately charged at 70-80%, then slowly the power is reduced until it reaches full saturation.

Why should you buy a wireless charger for your smartphone?

Although the wireless charging is a bit slower than using the adapter cable, there are some situations that make it particularly advantageous. First of all, the wireless charger allows you to have more order on the support surface. It is therefore ideal for those who do most of their work at the desk, such as lawyers, notaries, web designers, architects, but also secretaries, bloggers, and students can use it for its extreme practicality. This accessory also prevents the continued use of the cables from wearing or breaking the USB input on the electronic device. The wireless chargers are available in different shapes, sizes, and colors that allow you to choose the one that combines more not only on the phone but also to the personality of the individual user. Who owns many electronic devices can count on the universality of the wireless charger to keep all its terminals always at maximum efficiency.
