1, QI certification means the standard certification of the wireless power supply Technology Alliance. QI Certification Overview QI certification is a set of standard certification developed by the Wireless Power Supply Technology Alliance. With wireless technologyWith the continuous development of technology, wireless charging function has been widely used in mobile devices such as smart phones and tablet computers. In order to ensure the wireless charging functionality and security of these devices, WPC has launched the QI certification standard.
2. Qi (pronounced "chee") is derived from Asian philosophy and stands for "key energy", meaning invisible energy. QI certification is the mainstream technical certification for wireless charging products, indicating that the product has reached high quality standards in terms of safety and versatility.
3, Qi certification refers to the wireless charging standard developed by the Wireless Charging Alliance (WPC)The certification of. The Wireless Charging Alliance (WPC) is a global organization dedicated to developing and promoting standards for wireless charging technology. The wireless charging standard developed by the organization is called the Qi standard, and any charger with the Qi logo can wireless charge any rechargeable device that meets the Qi standard.
4, QI certification is the Wireless charging alliance certification, that is, WPC certification (Wireless? The Power? The Consortium is a collaborative group of independent companies that aims to create and promote widespread market adoption of products compatible with all rechargeable electronic devicesInternational wireless charging standard Qi. QI certification is an authorized mark for wireless charging products, and only products that have been rigorously tested to ensure safety, interoperability and energy efficiency can use the QI certification mark.
5, Qi certification: the universal language of Wireless charging industry Qi, the full name of the wireless charging Alliance (Wireless Power Consortium, referred to as WPC) masterpiece, it defines a global universal wireless charging standard. This standard with "convenience" and "versatility" as the core, to ensure that different brands of products only need to have the Qi logo,'> What to pay attention to when buying wireless charger 1, we should also pay attention to his heating effect when choosing, because with a wireless charger, if it is very serious when in use, then it will certainly have a loss of transmission. Who says we have to look at what material the wireless charger is made of when we choose? Whether to press metal with glass or plastic. Finally, when we choose to look at the five-star red flag, there are no other functions, which is also a basis for choice.
2, the temperature must be controllable: there will be a certain amount of power loss in the process of wireless charging, this part of the powerConverting to heat will keep your phone and wireless charger warm. As we all know, AirPower was also abandoned by Apple because it could not solve this problem. A high-quality wireless charger, can control the temperature below 40 ° C, will not be particularly hot. And has a temperature control function, automatic power off when the temperature is too high.
3. Safety should always be considered when purchasing wireless chargers. Look for chargers with built-in safety features, such as temperature control, foreign object detection, and overcharge protection. These product details prevent overheating, so the wireless charger won't damage your smartphone or other devices. Safety certifications such as CE (European Compliance), RoHS (Restriction of Hazardous Substances) and FCC (Federal Communications Commission) also give you peace of mind.
4, try to choose more than 10W power With the more mature technology, more and more people pursue charging speed, buy a high-power wireless charger, the future software system upgrade can also be used. It is recommended that when purchasing wireless charging equipment, try to choose a wireless charger with a power of more than 10W.
5, pay attention to the temperature of the wireless charger, high-quality wireless charger is able to control the temperature below 40 ° C. requireTemperature control function, the temperature exceeds the appropriate range of automatic power off. Wireless chargers have a conversion efficiency problem, the current mobile phone wireless charger conversion efficiency is more than 60%-80%. Under the same conditions, the higher the efficiency, the faster the charging speed. However, efficiency is not the only factor determining charging speed.
6, the above price source network, only for reference) more wireless charger price reference buy wireless charger to pay attention to what to buy wireless charger, pay attention to consider a number of aspects of the problem, including: choose vertical or flat lying flat lying advantages can be placed at will to the charging area can be chargedYou don't need to plug it in or anything.
1, Magotan wireless charging shows a foreign body, mainly refers to the existence of ferromagnetic metal. Regarding the display of foreign bodies, there are two main reasons: eddy current effect: The ferromagnetic metal itself is a closed loop. When a ferromagnetic metal is placed in a changing magnetic field, the magnetic flux through this closed loop changes, creating an electric current inside the metal. This current flows through the metal causing a loss that causes the metal to burnIt's hot.
2, Magotan wireless charging foreign body problem analysis: Foreign body usually refers to a magnetic metal, that is, magnetic substances. When such substances are in a change of magnetic field, according to the eddy current effect, an electric current is formed inside the metal, causing it to heat up. This means that when there is a magnetic substance on the wireless charging board, it may lead to a loss of energy, which poses a potential threat to the receiver and transmitter of wireless charging.
3, Magotan wireless charging does not respond may be caused by the following reasons: the mobile phone is placed incorrectly: When using the car wireless charging board to charge the mobile phone, it is necessaryMake sure the back of the phone is properly attached to the charging pad so that the wireless charging function can be activated normally. There is a foreign body between the mobile phone and the charging board: Wireless charging needs to ensure that the back of the mobile phone and the wireless charging board are completely fitted, if there is a foreign body in the middle, it may affect the charging effect.
4, Magotan wireless charging does not respond for the following five reasons: the mobile phone is placed incorrectly. When you use the car wireless charging board to charge the phone, the back of the phone needs to be placed on the charging board in the direction to enable the wireless charging function to activate normally. If the location is incorrect, rearrange the phone. There's a foreign object between the phone and the charging pad. UseWhen charging the wireless charging board, the back of the phone and the charging board need to be fully fitted.
QI certification mainly covers the evaluation of the performance, compatibility, security and other aspects of wireless chargers and receivers. Qi-certified wireless chargers can provide a stable power supply for devices that support the QI standard, while ensuring the safety of the device during the charging process. In addition, QI certification also involves the verification of communication protocols between devices to ensure good interoperability between devices.
Qi is a wireless charging standard developed by the Wireless Charging Alliance (WPC). The statement on the Internet about the "Apple Qi certification" actually refers to the Apple phone to obtain the Qi certification mark, must pass the Qi certification process. Attention should be paid to distinguishing between related concepts. Qi certification Type Qi certification is divided into the following three types: - Qi-BPP certification: The product supports less than 5W power, using the Qi protocol, must pass the BPP certification.Wireless charging Qi certification content: including Compliance test (Compliance test) and compatibility test (Interoperability Test). The compliance Test was conducted by the Authorized Test Lab (ATL) with 5 samples.
