How does wireless charging work?
Wireless charging has never been more relevant or realistic than it is right now, with advances being made across the board and Apple revealing their MagSafe system of Wireless Chargers. Charging without cables has gone a long way since its early roots, and it has finally shed its reputation as an ineffective and poorer alternative for conventional charging methods. With reports that Apple and other tech companies want to get rid of charging ports entirely, now is as better time as any to grasp how wireless charging works.
Magnetism is used to convey energy in wireless chargers. Wireless charging is based on a loop of coiled wires encircling a bar magnet, which is known as an inductor. When electricity flows through the coiled wire, it forms an electromagnetic field all around magnet, which can be utilized to transfer electromagnetic power (voltage) to things nearby.
Consider it this way: electricity flows from your wall socket, down the wireless charger’s wire, and into the coil of wire that surrounds the magnet. The magnet uses its magnetic force to capture all of the electrical energy when it reaches the coil around the magnet. A cloud of electricity forms around the wireless charger as a result of this. Sorry, physicists, but that’s a simplified version of the actual process, but it gives you an excellent idea of what’s going on in your wireless charger.
Any device that can be charged wirelessly has its own charging coil inside it, which is connected to the device’s battery and ready to accept the electromagnetic impulse. The electromagnetic field (electrical cloud) interacts with the coil in your gadget, causing a current to flow through it. This is due to the coil’s ability to transform magnetic energy into electrical energy (or direct current, to be more precise), which can then be used to charge your device’s battery.
Consider putting your item, say your phone, over the top of your wireless charger as an extension of our ‘electrical cloud’ thought analogy. Your phone has a coil in it that can pick up pieces of electricity from the electrical cloud formed by your wireless charger. The coil in your phone collects all the electrical particles, converts them into a continuous stream, and then pours that stream into your battery. Isn’t it clever?
This is a simplified description of a complicated scientific concept, but it should help you understand how the charging process works.
Which Devices Can I Charge Wirelessly?
It’s not like every device can be wirelessly charged; it must be equipped with a charging coil that is attached to the battery. However, you’ll notice that an increasing number of products, particularly smartphones, are built with wireless technology. In recent years, Samsung, Apple, Sony, and LG, to mention a few, have all welcomed wireless charging technology, with some even beginning to develop their own wireless chargers. Apple, in particular, intends to make wireless charging a standard across their whole product range, with Apple Watches and some AirPods all supporting it.
Should I want to Purchase a Wireless Charger, which one do I go for?
Checking to make sure your wireless charger is Qi-certified is the most crucial factor to consider. Because of the growing popularity of wireless charging, the Wireless Power Consortium was formed, and they developed the Qi (pronounced “chee”) protocol, which governs how the charger and the device interact. This is a sophisticated protocol, but all you need to know is that Qi-certified chargers and gadgets function together. If you’re looking for a wireless charger for your device, you should look for one that is Qi-certified; it’s the most effective approach to assure your device’s safety. Non-Qi-certified chargers are more prone to have issues, the most prevalent of which being overheating. An overheating charger can cause harm not just to property, but also to you.
Do phone cases allow magnetic charging?
If you have done some physics, you know that magnetism passes through non-conductors. If the phone case is made of silicone, rubber, or plastic, this means that you can charge your phone with a wireless charger. As long as the phone itself is wireless charging enabled of course. Qyutcase is one of the vendors who sell such cases as most of their cases are made of silicone. You can find a wide variety of these cases here.
