Wireless charging was applied to the Apple Watch after three generations, until 2017 years old iPhone X/iPhone 8 support Qi 1 standard 5W wireless charging. Also in this year, Apple proposed the concept of AirPower charging pillow. The biggest highlight of AirPower is that it can arbitrarily place charging devices, allowing users to charge devices that support wireless charging such as iPhone, Apple Watch and AirPods at the same time.
Wireless charging is not a necessity for everyone, it is more like the icing on the cake. For heavy mobile phone users, high power fast charge may be more able to meet the needs. whileIf you're a light user, like me, then wireless charging may bring unexpected surprises and make your life more casual. The value of technology lies in whether it fits individual needs, and wireless charging may add a convenience to your life.
First, you need to buy a wireless charger. There are many kinds of wireless chargers, and you can choose your own charger according to your needs. Step 2: Connect the wireless charger Plug the wireless charger into a power outlet, and then connect the charger to the phone. There are two ways to connect: one is connected through the USB interface, and the other is connected through Bluetooth.
Electromagnetic induction, magnetic field resonance, electric field coupling wireless charging to charge the mobile phone principle. Most of the wireless charging on the market now uses electromagnetic induction, which is a widely used technology. The efficiency of charging is very fast. Many of the original accessories of the electronics factory are using this principle, and now we see that most of the Apple mobile phones on the market have this function.
There are two coils on the phone that create a magnetic field when the charging pad is turned on. The coil on the phone will generate alternating current, and then convert the alternating current into direct current, we can charge the phone. Though thisThe charging principle is very simple, but the manufacturing process is really complex, not as simple as we can currently imagine. First of all, the distance of wireless charging is too short, and the effect of wired charging is no different.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
The principle of wireless charging is electromagnetic induction, electromagnetic induction wireless charging uses the electromagnetic generation of magnetism, the electromagnetic induction principle of magnetic generation, that is, the mutual conversion of "electricity" and "magnetic". Another principle of wireless charging is magnetic field resonance, which is composed of an energy sending device and an energy receiving device. When the two devices adjust to the same frequency, or resonate at a specific frequency, they can exchange energy with each other.
Card wi.
2, first of all, users need to download and install Chengdu's official city card APP Tianfutong APP. Find and click on the Tianfu Card in the APP, then select recharge option in the page. According to the APP, users need to attach the bus card to the NFC sensing area on the back of the phone, so that the phone can read the bus card information and recharge the operation.
3, users only need to ensure that their mobile phone supports the NFC function, and the function has been turned on, you can download and install the Tianfutong APP, and complete the registration, login and payment mode binding in the APP. After the binding is successful, the user can generate the bus ride code in the APP, or input the bus card information into the NFC function of the mobile phone.
4. In Chengdu, passengers only need to ensure that their mobile phones have the NFC function and download the corresponding payment application, such as the Tianfutong APP, so that they can complete the fare payment through the mobile phone close to the NFC sensing area on the bus. This payment method is not only convenient and fast, but also reduces the use of cash and physical bus cards, providing passengers with a more modern ride experience. In addition, the security of NFC payments has also been widely recognized.
5, -** Applicable Area ** : In the "12 2" area (including Xindu District) of Chengdu City Center, passengers can use the Tianfutong NFC function to take the bus for free. - ** Device requirements ** : The user's smart phone or other portable devices must have NFC function, and the relevant Tianfutong NFC service has been opened.
6, Since June 2015, Chengdu can use mobile phone nfc instead of bus card. The specific implementation method is as follows: Need a mobile phone that supports NFC function. Mobile phones need to be equipped with a dedicated NFC calling card to go to telecom, mobile and Unicom companiesConsulting management. Note: Replace the NFC-SIM card, the original mobile phone number will not change. After opening the NFC-SIM card, go to the APP store to download the Tianfutong APP, bind the Tianfutong card and recharge online.
1. Huawei recently released a magnetic wireless charging bank, which is suitable for the Pura 70 series mobile phone wireless fast charging. This Huawei universal magnetizing mobile power supply is light and portable, compact design, and compatibleA charging mode that provides a second battery-like experience. Charging head network statistics of Huawei over the years to support wireless charging models, this magnetic wireless charging bank compatible with most of them. In addition to Huawei, the Xiaomi magnetic charging treasure 2 is also worthy of attention.
2, magnetic charging treasure brand is better: RAVPower, Mophie, ZMI purple rice, MI millet, Momax Momis. RAVPower: RAVPower is a domestic brand, but also a well-known cross-border electricity brand, mobile power is its main product. So far, the products have been exported to some Europe and the United StatesHome.
3, the top ten brand charging treasure list has millet, Pinsheng, Huawei, Patriot, Roma Shi, Philips, Anker, Bysi, Yubo, Scud. Xiaomi is a well-known brand under Xiaomi Technology Co., LTD., which wins the trust of consumers with high-quality products. The mobile power supply adopts 2-in-1 wireless charging design, which is a magnetic wireless charging treasure when traveling. When using the desktop, gently put the second to change the vertical wireless charger.
4, relying on the big data of the whole network, according to brand evaluation and sales, the top ten brands of charging treasure in 2023 are selected, and the top ten are scoredIn particular, Philips /Philips, Romas /Romoss, Green Link /UGREEN, Millet /MI, HUAWEI /HUAWEI, Pinsheng /PISEN, Yubo /YOOBAO, BSI /BASEUS, REMAX /REMAX, Beijing Tokyo Manufacturing.
5, OPPO and Xiaomi, Huawei are in the field of smart phones have a certain visibility, and in recent years, the increasing demand for smart power also let OPPO began to launch smart power products. Yubo Yubo was founded in Shenzhen in 2005, and has been developing "quality changes life"As the core of the brand development, the concept has launched mobile power supplies, mobile phone batteries, wireless routers, Bluetooth speakers, Bluetooth headphones and other products.
6, secondly, the charging efficiency of Anker magnetic charging treasure is also quite excellent. This is thanks to its optimized charging protocol and high-power battery combination. To give a specific example, Anker's magnetic power bank can charge an iPhone 13 to 50% in 30 minutes. This efficiency not only saves users a lot of time, but also means that in an emergency, the phone can be quickly restored.
