Wireless charging that does not work with cables | Digital Done

Almost all phones, smartwatches and other gadgets nowadays support wireless charging technology. Samsung has been providing this technology to its Galaxy flagship devices for four years. Apple has also recently introduced this technology in iPhones. Of course wireless charging is not new. In the 19th century, Nikola Tesla, the inventor of the electric field, introduced a method called magnetic resonant coupling to conduct electricity between two circuits. However, there have been no complete experiments to bring it to the masses during these centuries. It has so far appeared only in places like electric toothbrushes.

Many attempts of Wireless charging

Now there is a huge demand for wireless charging technology worldwide. There are more than ten wireless charging technologies in use in various forms. The goal of all is the same. Disables working with cables for charging different types of devices! It's not just for smartphones, but for all needs like laptops and kitchen accessories. On the other hand, there is a growing need for it in the healthcare, automobile and manufacturing sectors. Meanwhile, the use of many Internet of Things devices to make people's lives easier has also been on the rise recently. Various manufacturers are interested in setting up wireless charging without having to connect cables to them.

How does it work? Wireless charging

There are currently three main types of wireless charging systems in use. Among them wireless charging pads are the most popular. It does not work with cable to charge Samsung Galaxy Note or S series phones. Placing it on a wireless charging pod will result in the same charging on its own. Electromagnetic molecules are deposited in such charging pads. The second method is non-radiative charging. Also the third method is to supply power wirelessly up to a range of a few centimeters by using special charging bowls!

Broadcast of Wireless charging

It is not enough to just store electricity, the receiver coil is also needed to receive it. The induction coil on the wireless charging pad converts the electricity into an electromagnetic field, while a receiver coil is inserted near it to convert the received electromagnetic energy back into electricity. The main reason for not having this receiver coil in all devices is that it is not able to charge all phones and gadgets wirelessly as long as there is a wireless charging pad. That is why only phones with this feature can be charged wirelessly.

Wireless charging like for smartphones!

A closer look at the wireless charging pads we currently use for smartphones reveals that copper coils with a radius of a few inches are deposited in them. It is possible to embed only a limited amount of copper coils in a small wireless charging pad. Therefore, those pads can only supply power in small quantities. If copper coils can be deposited in large quantities, not only smart phones but also large devices can be charged wirelessly. For example, if copper coils with a radius of 25 cm can be used, power can be supplied wirelessly up to a distance of 25 cm, and even more electricity.

What is real wireless charging?

Of course what we are using now does not look like real wireless charging. Having to put the phone on a charging pad naturally makes many people doubt how wireless it is. Wireless means that electromagnetic waves must be transmitted in a room, or within a specific place, in the same way that signals are received through our Wi-Fi router. It should be able to supply enough power to all the devices in that range without the hassle of any cables or pads. The same goes for real wireless charging. But there is nothing to be discouraged about right now. Extensive research is underway to make this type of full wireless charging available to us. Within the next five to ten years we can enjoy real wireless charging. We are already using technologies like wireless ear buds and wireless display. If the wireless charging is complete in the same order, then the days of having to put cables in the museum are over. Let's wait for that moment.

Wireless charging - It is very popular‌

Wherever the mention of wireless charging comes from, it specifies what standard is being used for charging. Khazi (pronounced "chee") is the most popular wireless charging standard for smartphones. Phones from leading companies like Apple iPhones, Google Pixel, Samsung Galaxy all follow this standard. We also have some standard third-party chargers that meet the Khazi wireless charging standard, even if you look at various shopping sites like Amazon. The wireless charging docks you purchase should only have the wireless charging standard that your phone supports. Otherwise there will be no power supply between the two devices.

Wireless charging errors

Wireless charging needs to be fully developed. Wireless charging is still very slow compared to wired charging. Wireless charging also came with fast charging. However, it is much slower than normal fast charging. On the other hand, some people have a habit of charging the phone and carrying the phone in their hands and doing important things. This is not possible in the case of wireless charging. Be sure to place the phone on the charging pad. Otherwise it will not continue charging‌. Another thing to keep in mind is that wireless charging is not found in budget phones and other low-cost gadgets. The main reason for this is the high cost of implementing this technology. It will definitely take more time to come into full use.

Benefits of Wireless charging

Wireless charging is very convenient. You do not even have to connect a cable to your smartphone for charging. It is sufficient to place the phone on the wireless charging pad whenever charging is required. This will prevent problems such as loose and damaged USB ports. Most importantly, wireless chargers have come a long way in supporting a wide variety of devices. This is enough if you have a charging pad. It is sufficient to place various devices required for charging on it.
