The significance of wireless charging is that people cannot feel the existence of the charging process. Charge it whenever you want, use it whenever you want, it’s a feeling that you’ll fall in love with it. There are generally two reasons for complaining about wireless charging, slow charging and inability to charge while playing games. Such people make the mistake of treating wireless charging and wired charging as the same thing. But the two exist to solve different problems. You can't say to the broom. The disadvantage of the broom is that you can't mop the floor. If you have a low battery and need to go out urgently, use fast charge to quickly recharge. If the battery is low, and it is troublesome to charge it, then wirelessly charge it and put it away. If you need to charge your mobile phone when you are at a desk, and you need to use your mobile phone when you are working, that is also the absolute leader in wireless charging experience. Especially the vertical charger can be used as a stand without the need to take the mobile phone.
Wireless charging is to realize the energy transmission between the power supply and the electric equipment in a non-contact wireless way. Currently available wireless charging technologies include electromagnetic induction, magnetic resonance, radio wave, ultrasonic, infrared laser and electric field coupling. The most widely used wireless charging technology is electromagnetic induction, which has the advantages of high conversion efficiency and short-distance charging. The principle of electromagnetic induction technology is that a changing current flows through a coil to generate a changing magnetic field, and the paired coils are coupled to generate a corresponding voltage for charging.
Among them, electromagnetic induction is the most used technology in the current mobile phone market, and magnetic resonance technology has huge future potential and is expected to become the mainstream technology. The principle of electromagnetic induction is that the power transmitting coil and the power receiving coil are built in the charging base and the mobile phone terminal respectively. When the two are close, the transmitting coil (transmitting coil) is based on the alternating current of a certain frequency in the mobile phone receiving coil (receiving coil) ) Generates a certain current, thereby transferring electric energy from the transmitting end to the receiving end, and supplying power from the charging dock to the mobile phone. The electromagnetic induction method is relatively simple to implement and is currently the most mainstream solution in mobile phones. The main problem is that the transmission distance is severely limited. Magnetic induction wireless charging can only support one-to-one wireless charging, and it has defects such as low charging power and short charging distance. In order to achieve one-to-many wireless charging, improve power and have more flexible and free charging distances, magnetic resonance wireless Charging has begun to receive industry attention.
The current wireless charging has not been able to achieve true wireless charging anytime and anywhere. Instead, the mobile phone is placed on a charger that can be charged wirelessly and conducts electricity through electromagnetic waves, thereby adding power to the mobile phone.
The charging loss rate of wireless charging is currently relatively high, around 30%. Take an Apple mobile phone as an example. One hour of wireless charging is equivalent to 15 minutes of wired charging. Of course it is needed. The most suitable scenario is in an office environment. Put the phone directly on the wireless charging stand. To read the information, you can reach it in front of you with your hand stretched out, so you don’t need to unplug and plug it in every time. The principle of wireless charging is electromagnetic induction, which is a physical phenomenon in which electricity and magnetism can be transformed into each other under certain conditions. At present, the mobile phone wireless charging base converts electricity into a magnetic field, and the wireless charging coil on the mobile phone can convert the magnetism into electricity to supplement the power of the mobile phone.
Will Wireless Charging Actually Replace Wired Charging?
The question of whether wireless charging will replace wired charging is not as straightforward as it sounds. The question of when and if wireless charging will become common depends on your perspective as a consumer of the technology.
If you’re a critic of wireless technology, then it’s a matter of if. Critics believe that wireless charging will never replace wired charging if the technology is not refined. It’s almost impossible to control electromagnetic fields in free space.
Even the Tesla coil cannot control the path of air
ionization when attempting to convey an electric spark to the device. Hence, there’s
little chance, if any, that wireless technology will ever be refined beyond its
current state.
However, if you’re a proponent, then it’s reasonable to argue that it’s when wireless charging will render wired charging obsolete, despite it being criticized as not fully “wireless”. As it stands now, wired charging is more popular than wireless charging.
Few people are aware of wireless charging. This technology is currently available only on high-end electronic devices, which are still out of reach for the many. It’s still at its infancy, and may not be as developed as wired charging. It’s infiltrated into tablets, smartphones, wearable devices and other small handheld gadgets.
However, mobile devices are increasingly adopting wireless
technology, and sooner rather than later wireless charging will become just as
common as wired charging. In addition, no standard as of late has been
developed for wireless charging. There’s also a trend toward integrating
wireless charges with household devices such as gadgets, furniture and so on.
What’s Wireless Charging?
It’s a process that does not require a physical connection of electric cables to recharge batteries of electronic devices. A microwave or an electromagnetic induction facilitates the communication between the device and the power source. The pad houses a coil of copper which is also housed by the device.
The pad uses an alternating current
(AC) power source to create a changing magnetic field in the area surrounding
the pad. This fluctuating magnetic field induces an electric current in the
device and hence charging the battery. Whereas a wireless charger requires a
pad, onto which a mobile device is placed, a wired charger requires an electric
cable, which connects a mobile or gadget to a charging port.
How Convenient is
Pad Charging?
Proponents argue that you’ll no longer need to carry many
chargers for a variety of devices because more and more devices are becoming
wireless chargeable. It’s inevitable that wireless charging will play a key
role in meeting the demand for a standardized, safe, portable and efficient
alternatives of power recharging. The user is safe from electric shocks. It’s
also easy to handle, and you don’t need to maintain it.
Critics of wireless technology argue that it’s impractical, and
rather than making charging easier, it complicates it and inconveniences users
further. In addition, wireless charging is not “wireless” as advertisers have
purported it to be because it still requires a cable connection to a wall.
One critic briefly puts it, “[p]ad charging, I guess for me, will be tad bit uncomfortable. You have to keep a phone on it for charging. It is gonna be inconvenient to use it while charging.”
The basis of this critic’s argument lies on the premise that the current wireless technology is fake. It’s not popular and widely adopted because of its inconvenience. Pad charging complicates the experience of the users of smart devices such as Android or iPhone devices.
The charging pad is much more complex than a standard USB wall charger power supply and cord. That means they are more expensive. In addition to being more expensive, they are also less portable. They require a surface on which to rest, preferably flat and level. There’s not a spot in my car that is either flat or level, so I can’t reliably use a charging pad in my car. I probably could get a cradle that holds the phone firmly, but the cradle wouldn’t be useful outside of my car.
In summary, the question of whether to adopt a wireless technology lies in its practicality and refinement. While it’s been proved that it’s not practically possible to relay charges through an ionized air space, it is incumbent upon the proponents of wireless technology to prove the critics wrong by demonstrating that Nikola Tesla’s dream of transmitting wireless power is actually possible.
Wireless charging is becoming more and more standardized, and even more common. Popular smartphones such as iPhone 8, iPhone 8 Plus and iPhone X support wireless charging. If you want to charge your smartphone wirelessly, you’ll need a smartphone that supports wireless charging at first.
After you chose a smartphone, a compatible wireless charging plate is necessary to place your phone on. Essentially, the fundamental of wireless charging is that it uses magnetic induction to transmit energy. There are five mainstream standards of wireless charging on the market, Qi, Power Matters Alliance(PMA), Alliance for Wireless Power(A4WP), iNPOFi and Wi-Po. Different standard has different benefits. Also, different smartphone matches different standard wireless charging pad.
Here I would like to recommend Anker 10W fast charge wireless charging pad which is made for all Qi-enabled phones, like iPhone X and iPhone 8 line, Samsung Galaxy line from S7, it’s much faster than traditional 3.5-5W chargers since it’s able to support 7.5W-10W output.
If you just bought a new or expensive smartphone, what you would do at first would possibly buy a case or a popsocket for it, let alone it is an iphone X . You want to protect the new gadget, meanwhile you want to enjoy the convenience of wireless charging. So would wireless charging still work with a case or popsocket? There’s plenty of debate on both sides of the argument.
One comment on MacRumors said his popsockets will not allow it to make a good connection to the wireless charger. It will connect at first, but then loses the connection within like 30-60 seconds. That is nonnegligible for one love the popsocket, and can see it being really handy for the iPhone X. Compared to smartphone case, popsocket works better in my point of view because it takes up a less space and you can still lay the phone flat on its back even with it attached. In another aspect, someone bought the popsocket and his wireless charging still works without a case on
There are different situation comes out when people wireless charging their smartphones with the case or popsocket. One of the key factors affects the wireless charging is that the material. For example, the rubber material is better than the metal material. It can transfer faster and more stable. While some case and popsocket are made of the hybrid material, it is more difficult to distinguish the problem source. Beyond that, a compatible and suitable wireless charging plate such external factor as I mentioned also affect the wireless charging.
Do you have
experience with a popsocket or a case with wireless charging? How do you
deal with the situation? Welcome join the discussion.
