1, Qi wireless charging refers to the application of Qi wireless charging standard in the way of electromagnetic induction for mobile phones, cameras and other handheld low-power equipment wireless charging technology. Qi Wireless charging standard by the Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) initiated and developed, is currently the world's widely recognized wireless charging standard.
2, Apple's Qi wireless charging is oneWireless charging technology based on Qi standard. The technology can use induction and magnetic resonance to transfer power from the charger to a device that supports wireless charging, such as iPhone, AirPods, and AppleWatch. With Qi wireless charging technology, you only need to place the device that supports wireless charging on a compatible charging pad or charger to achieve charging, without using a traditional charging cable to connect the device and charger.
3, Apple wireless charging protocol is as follows: Qi wireless charging protocol: Qi is the wireless charging standard launched by the International wireless charging Alliance, most of themMobile phones, TWS Bluetooth headsets, tablets and other devices that support wireless charging use Qi wireless charging protocol. Since the iPhone 12, Apple has joined the MagSafe wireless charging protocol, which is essentially a private transformation on the basis of Qi, supporting magnetic absorption, and the power can be up to 15W.

5, Qi wireless charging is a electromagnetic induction for mobile phones, cameras and other handheld low-power devices wireless charging technology, the need to use a wireless charging board, the device is placed on the charging board, can be up to 5 watts of power for the iPhone or other Qi support equipment to charge. Qi is the wireless charging standard, driven by the world's first wirelessCharging technology standardization organization proposed that the wireless charging standard has two characteristics of convenience and versatility.
6, Qi is the Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard Wireless charging standard qi; Then why will there be Apple qi certification online Wireless charging standard qi? That is because Apple's mobile phone wants to play qi certification logo is also to do qi certification! So we don'tCharging brings a convenient, efficient and reliable experience for people. Qi is the world's first standardization organization to promote Wireless charging technology - wireless charging Alliance (Wireless Power Consortium, hereinafter referred to as the "alliance") launched the "wireless charging" standard, with convenience and versatility of the two characteristics. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.

Apple wireless charging protocol is as follows: Qi wireless charging protocol: Qi is the wireless charging standard launched by the International Wireless charging Alliance, the vast majority of mobile phones, TWS Bluetooth headsets, tablets and other branchesThe devices with wireless charging all use the Qi wireless charging protocol. Since the iPhone 12, Apple has joined the MagSafe wireless charging protocol, which is essentially a private transformation on the basis of Qi, supporting magnetic absorption, and the power can be up to 15W.
QI certification is the Wireless charging alliance certification, formerly known as WPC certification is the first letter of the Wireless Power Consortium (wireless charging Alliance), which belongs to the certification requirements of a technical organization, similar to SIG's Bluetooth BQB certification. And regular countryOr regional certification is not directly related, that is to say, it can be used globally.
Qi is the world's first standardization organization to promote Wireless charging technology - Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) launched the "wireless charging" standard, with convenience and versatility. Different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.

Qi Wireless charging standard by the Wireless charging Alliance (Wireless Power Consortium, referred to as WPC) initiated and developed, is currently the world's widely recognized wireless charging standard.
Qi wireless charging, simply put, is a use of electromagnetic induction principle, through the Qi standard for mobile phones, cameras and other small equipment wireless charging technology. This standard is developed by the world-renowned Wireless Power Alliance (WPC) has been widely accepted and applied by the industry, including Apple, Samsung, Nokia and other global giants have adopted Qi as the wireless charging standard for their devices.
Qi is the world's first standardization organization to promote Wireless charging technology - Wireless charging Alliance (Wireless Power Consortium, hereinafter referred to as the "alliance") launched the "wireless charging" standard, with convenience and versatility two characteristics. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
QiIs a Wireless charging standard created by the Wireless Power Consortium (WPC), its biggest feature is based on electromagnetic induction technology, strong compatibility, can achieve charging between different brands, different designs of equipment. In addition, the Qi standard also supports the simultaneous charging of multiple devices, automatic control of charging power and charging protection, which improves charging efficiency and safety, and brings a convenient, efficient and reliable experience for people to charge.
2, First of all, not all wireless chargers on the market can be competent for watch charging. Many products do not clearly label the radiation value, which is somewhat worrisome. Because the radiation standards for wireless charging technology are not yet perfect, we need to focus on the current regulatory requirements,As stipulated in the Regulations on Electromagnetic Radiation Protection, the electromagnetic radiation of the user in continuous contact with the wireless charger within 24 hours shall not exceed the specific absorption rate (SAR) limit of 0.02W/kg.
3, taking 1000mAh capacity lithium battery as an example to calculate the radiation of the wireless charger. 50% charging capacity is about 7~8Wh. If it is required to be full for about two hours, the maximum charging power should reach at least 1W (the maximum power of the GSM900 mobile phone is about 2W); Since the wireless charging method of the phone is to place the phone above the charger rather than inside, the radiation leakage rate can be not small.
4, the test found that wireless charging standard qi : Using a high-sensitivity radiation tester, the radiation value of the wireless charger is between 150 and 180, although compared to the 250 to 627 in front of the computer screen or the thousands of phone calls are smaller, but the cumulative effect may not be ignored. At the same time, when wireless chargers, mobile phones, computers and other electronic devices are used together, the radiation value will increase significantly.
5, according to the Electromagnetic Radiation Protection Regulations, the average radiation absorption radiation rate of the whole body within 24 hours a day for 6 minutesIt should be less than 0.02 w/kg. However, there are no specific standards for wireless charging. Experts say that while there are national standards for traditional mobile phone chargers, there should be national industry standards for emerging wireless charging devices as soon as possible. The Qi wireless charging standard uses a low frequency non-ionization frequency (110-205khz) that is harmless to the human body.
6, expand knowledge: According to the test of relevant institutions, the radiation amount of Apple 12 is 0.137W/m when the wireless signal is strongest, and the standard value is less than 0.4W/m. In the range of radiation perceived by human body, the highest value of electromagnetic radiation energy appears in the proactive regionBut it is also far below safety standards. The impact of electromagnetic radiation on the human body varies from person to person, and it is generally believed that long-term exposure to high intensity electromagnetic radiation will have a negative impact on human health.
