Wireless charging is on the brink. The end is near for short iPhone chargers and the need to replace them every other month. No longer will you have to fight over an outlet to charge your dying laptop or cell phone or run to the other room to quickly grab your charger before you lose your last 1%. Soon, you will be able to simply place your phone or laptop on a table and begin charging with the help of a wireless charging mat.
Also known as inductive charging, wireless charging uses an electromagnetic field to transfer energy between two objects, i.e. a cell phone, computer, or tablet. The charging station consists of induction coils that create the alternating electromagnetic field, which is then converted into an electrical current to charge the desired device. Advantages of wireless chargers include convenience, protected connections, and durability, while disadvantages include lower efficiency, wasted heat, and slower charging.
