There are dozens of things in an average home that require a regular electrical current source to function, but some have to be recharged periodically, such as laptops, tablets, cell phones, electric toothbrushes, mp3 players, razors, etc. You can also buy high power wireless charger via https://www.kewlabstech.com/.

The only thing connected with these devices is the electrical cable and the greater the reach of these devices, the more cables they will be. Sadly, any number of dusty cables makes for a very ugly sight. Plus, they can be poisonous and pose the likelihood of them falling off, unless you're careful.
The introduction of electric chargers, which eliminate the use of cables, is a boon, as by using them, one person recharges or operates multiple devices.
It is known that with the support of electromagnetic fields we could move electricity between two nearby objects, located close to each other, even without connecting the two by cables. As soon as we pass an electric current through an electric wire, an electric field builds on that electric wire.
Instead of working with a straight wire, if we use a coil-shaped wire, we could improve the magnetic field. By placing another coil near the previous one, the magnetic field causes a current in the secondary coil. That is fundamentally the principle of performance of wireless chargers, in which electricity is transmitted to the main coil of the charging device.
