Wireless charger at least buy a big brand, poor quality or do not use, because the charging voltage may not be standard, easy to damage the battery.
You said it was inferior wireless charger, it must be risky to use! Although it is safer than wired charging, it is better to choose a regular brand for wireless charging products.
First of all, do not use poor quality wireless chargers, because poor quality chargers may have overcharge, high heat safety problems, and there is also a risk of damage to the phone. The second is when we need to spend a long time without using mobile phonesIt is best to unplug the charger to avoid overcharging. In addition, mobile phones and chargers cannot be placed in places where electrical appliances cannot be placed, such as in water or near a fire source, which can easily cause danger.
First make sure your phone has wireless charging capability. Then if there is a wireless charging function, and wireless charging function is good, in other people's wireless. If the charger can be used, it means that you bought this wireless charger has a problem, you contact the business to return. Or ask the merchant to send you another one.
CB certification benefits: 1) can convert foreign certification certificate If you have obtained CB test certificate and CB test report, you can directly apply for certification in other countries.
First, the main benefit of applying for CB certification is to facilitate the conversion to various certification requirements at home and abroad, such as VDE, GS, UL, CU, SASO, Australia RCM and China CCC certification. Second, the credibility of CB certification and reporting is relatively high, and it can also be directly obtained in many countries such as Southeast AsiaNational or regional buyer recognition.
CB certification benefits can be converted manufacturers can rely on a CB test certificate issued by the NCB to obtain the national certification of other member States of the CB system directly recognized or approved by other countries to obtain a CB certificate, and then apply for CCC, CQC, GS, VDE, UL and other certifications, in principle, Only a small number of additional country variance tests are required to obtain the corresponding certificate.
Applications for CB test certificates may be submitted by the applicant to any "Certification/recognition" NCB covering the product range. (2) The applicant may eitherIt may also be an entity authorized to act on behalf of the manufacturer. (3) The application may include one or more factories producing the products in one or more countries.
The HONOR V40 standard charger is super fast 11V/6A; Wired charging: The phone supports a maximum super fast charge of 11V/6A, compatible with 10V/4A or 5V/5A or 5V/5A super fast charge, compatible with 9V/2A fast charge. The actual charging power varies depending on the scenarioCan change, please refer to the actual.
The standard charger of HONOR V40 mobile phone is super fast charge 11V/6A, wired charging: the phone supports the maximum super fast charge 11V/6A, compatible with 10V/4A or 5V/5A or 5V/5A super fast charge, compatible with 9V/2A fast charge.
The HONOR V40 is equipped with a Guet 1000 processor, uses 120Hz high-brush screen, and supports 66W wired fast charge and 50W wireless Super fast charge. The 66W wired Super fast charge in the HONOR V40 uses a single-cell three-pole ear fast charge scheme, which uses electricityThe core split technology can reduce the heat of the cell and avoid the loss of battery capacity splitting. Compared with the dual cell battery, the former has less loss and longer battery life.
The HONOR V40 supports wireless charging, which supports 66W wired super fast charge and 55W wireless Super fast charge, but you need to purchase a wireless charger when using wireless charging. The HONOR V40 has a 4000mAh battery, and the media has tested its battery life, and the charging test began after the phone ran out of power and automatically shut down, and it can reach 38% power in 10 minutes, and 74% power in 20 minutes, reaching 100% Charge only takes 34 minutes.
According to the latest news, Honor's new flagship V40 series has finally obtained the national 3C product certification after a series of expectations, revealing some of its important features for us. One of the most notable is that the HONOR V40 will enhance the significant charging experience, up to support the amazing 66W super fast charge technology, compared to the 40W wired fast charge of the previous generation V30, is undoubtedly a major leap.

1, wireless charging transmission circuit board (PCBA) refers to the electronic components used to achieve wireless charging function, which mainly includes a circuit board (PCB) and various electronic components installed on the circuit board. Together, these components form part of a complete wireless power transmission system, which is responsible for converting electrical energy into wireless signals and transmitting them to receiving devices. Wireless charging technology is usually based on electromagnetic induction or magnetismThe resonance principle works.
2, Wireless charging transmission circuit board (PCBA) is an electronic component used to achieve wireless charging function. It is one of the core components of the wireless charging system, responsible for converting electrical energy into wireless energy signals and transmission. PCBA usually consists of multiple components, including power supplies, inductors, circuit control chips, filters, and connectors.
3, PCB (Printed Circuit Board), the Chinese name is called printed circuit board, also known as printed circuit board, is an important electronic component, is the branch of electronic componentsThe support body is the carrier of electrical connection of electronic components. Because it is produced by electronic printing, it is called a "printed" circuit board.
4, PCBA is the abbreviation of the English Printed Circuit Board Assembly, that is to say, the PCB empty board through the SMT on the piece, and then through the DIP plug-in of the entire process, referred to as PCBA. The difference between PCBA and PCB: From the above introduction, it can be known that PCBA generally refers to a processing process, which can also be understood as a finished circuit board, which is after the process on the PCB board is completedTo be a PCBA.
