Powering your iPhones, Android devices wirelessly
Wireless charging has been around for a few years now, but it's fair to say it hasn't take off to sky-high heights. As with any fresh technology, standard needs to be set, technology developed and ultimately pushed out to consumers. Now Apple is getting in on the scene with its flagship iPhone ☓, plus the iPhone 8 and iPhone 8 plus smartphones coming with wireless charging capabilities.
What is wireless charging?
It is the transfer of power from power outlet to device without the need for connecting cables; it is self explanatory. Wireless charging involves a power transmitting pad and receiver, sometimes in the form of a case attached to a mobile device or even built into the phone itself.
How does wireless charging work?
- Inductive charging
- Transmitter and receiver create electromagnetic field
Wireless charging is based on inductive charging whereby power is created by passing an electrical current through two coils to create an electromagnetic field.
When the receiving magnetic plate on the mobile device comes into contact with the transmitter or at least within the specific range, the magnetic field generates an electrical current within the device. This current is thereby converted into direct current, which in turn charges the in-built battery.
What are the standards for wireless charging?
Qi and powermat
Qi adapted by majority of smartphone manufacturers
Powermat is less recognised.
There are a few standards floating around. The main you could have likely heard about is Qi (pronounced chee). Qi is a standard that has been developed by the Wireless Power Consortium for inductive charging over distance of about 40mm.
Qi has three separate power specifications, beginning with low power, which can deliver up to 5W and is primarily used in charging mobile devices and SmartWatchs - the WPC has said this will be tripled to 15W in the future. There is a medium power spec which can deliver up to 120W which are used for monitors and laptops and there is a high spec which delivers up to 1KW which can be used used to power things such as the kitchen utensils.
Many of the manufacturers have adopted Qi wireless charging :Samsung, Huwai, Motorola, Nokia, HTC, and Blackberry.
The other standard that has the potential to steal the limelight from Qi is PMA or Powermat. It too works on inductive charging, but in 2014, PMA signed a deal with another wireless charging consortium, the Alliance for Wireless power (A4WP). It works on magnetic resonance charging instead. The deal means the two companies can exchange technology and patent, to help evolve wireless charging at a much faster rate.What phones support wireless charging?
The majority of phones only support Qi wireless charging. However, some, such as the Samsung Galaxy S6 and S6 Edge, along with the Blackberry Priv, support both Qi and PMA standards. They both have technology built into their chassis too. Other major phones have built in support for Qi charging. Others might support Qi charging on a regional basis, such as the United States version of the LG C6 and there are others small manufacturers such as the Yotaphone 2.

@sulev I hope you find this article helpful and please kindly upvote and resteem to your friends 😀
Plagiarism will get you no where.
What do you mean by that? Please I don't appreciate that, so I can't write about wireless charging? What's the biggie in that?
You see how Cheetah provided a link? That link is where this information was taken from. Cheetah is a bot that identifies when someone has copied material from another website and failed to provide that site as a reference in their post.
Copying and pasting material from other websites won't bring you success here. It will just get your posts flagged, and eventually Cheetah will put you on its backlist which is not something you want to experience.
You can write about any topic you want, and in all honesty you can plagiarise as much as you want as well. It all boils down to what you want your Steemit experience to be. Something positive or something not so positive?
I'm really pained by this accusation, can't a girl know about wireless charging or is this how you guys bully people here? I worked my ass off get to 29 now I'm back to 28. This isn't fair! You can't just think someone is copying another person, I wrote where I got d pictures, what else do you people want? Please sir, I'm not cheat n next time, come up with a proof!
OK I think I see the main paragraph that Cheetah would have picked up. It's this one that I've taken directly from the website that Cheetah provided:
I've removed my flag because most of the remaining article seems to be fairly original or at least quite modified. My recommendation is to include any site that you source information from as a reference in your main post. This will protect you in the future.
Also, going from 25 to 40 or so should be pretty easy and fast. Maybe think about what type of content you can produce that will be attractive to your readers. Tech stuff is great, but maybe look at what people want to read about in this field.
Oh and there is no intention on bullying people. Plagiarism is all too common here which is why people pounce on it when it's spotted. We try to keep Steemit as free from it as possible despite people trying to do it constantly.
Noted, thanks.
