How Wireless Chargers Work: Everything To Know About


Convertible And Hybrid Laptops: Example Of New Technology

Sometimes when we are lying in bed at night and using our phones, the most annoying thing happens. Your phone says, “10% battery remaining. Please connect the charger.” You are in the most relaxed and comfortable position, almost ready to sleep. But then, you have to get up and connect your phone charger to your phone. If not to continue using it at that time, then for the morning and rest of the day. The solution to this is something that the world has been anticipating for a long time. The first time that the world saw something along the lines of the same was in 1901. This was when a Nikola Tesla attempted to bring it about. However, that did not work out. Over the past decade or so, the reality of wireless chargers has been coming true. The first attempt in the last decade for wireless chargers was for mobile phones. Samsung brought out theirs in the year 2014, and Apple did so in the year 2017.

What Is A Wireless Charger?

Wireless chargers are not exactly wholly wireless, as the name may suggest. You still do need a wire to charge the wireless charger itself. This is the difference between wireless and regular chargers. The wiring in a regular charger connects directly to the mobile phone. On the other hand, wireless chargers have wires which connect only to the charger (which only connects with the charger base). You are to place your phone on top of the device. This is as opposed to having to plug it in anywhere on the device. The charger bases come in different sizes. The size also depends on which phone it is, as does the design of the device. What also affects the same is which device we are talking about as well. It can be as large as the dashboard of the car. However, it can even be just the size of the base of any lamp.

It is possible that wireless chargers will now be compatible with all sorts of devices, and not only phones. This includes in-home devices and appliances and even robots. These chargers charge your phone very easily. It’s as simple as placing your phone on the table for a while, where, instead of the table, the surface you place the charger on is the charging base. The technology that goes behind wireless charging is pretty cool. It consists of two power sources coupled to transmit power signals of low intensity from one device to another: Vis-À-Vis, the phone, and the charger base. The two devices have two respective coils, the transmitter (for the charging device) and the receiver (for the device to which the charger is transferring the power). The charger continually sends signals to the device being charged via the coils and hence charges the phone. It works in a similar way that Bluetooth does. The difference is that Bluetooth is to exchange files between two devices, and wireless charging is to transfer power between two devices.
