The CE of wireless products takes two weeks, the price is not easy to say, four thousand to ten thousand are possible, depending on the specific product; ROHS is a European Union environmental certification, certification methods areThree, depending on customer requirements; Out of the United States does not necessarily need UL, unless your customer specifies this certification, but FCC certification is definitely required, because it is mandatory certification. I hope it helps.
Second: look at the certification, CCC certification (national compulsory certification) UN33 certification (battery certification) MSDS report (battery shipping/sea shipping report) CE certification (EU certification) CB certification (US certification). What kind of certification is done, it shows what kind of qualification. There's no certification, no product on the table. Third: Look at cases. Powerful supplier, shared chargingTreasure factory, there are many overseas cases.
Nank South Carolina Wireless charging treasure POW2 Nank South Carolina wireless charging treasure with hot sales, no doubt ranked first in the field of charging treasure. This charging treasure is fashionable, lightweight and portable, and supports 10W wireless fast charge and 18W PD fast charge, which has been recommended in the major media of digital technology, and is very popular among students in the digital circle.
Can bring the plane, the mobile power charger has CE certification, but no 3C certification can not be sold in the country, if the mobile power is sold separately, with USB cable to chargeAnd are considered to be "Qi certified" products.
Note: interop test interoperability testing in the Qi certification program will start charging from February 2020. According to WPC requirements, all test samples should be tested for compatibility with all previously certified samples. If the product tested is a wireless charging transmitter, then it needs to do compatibility testing with all WPC receivers that have passed the Qi certification.
Yes. According to vivo's official website, VivoX9Plus can be charged using a wireless charger that supports Qi certificationQi is a wireless charging standard that is supported by many mobile phone manufacturers.
At present, QI standard is relatively mature and occupies the mainstream. To buy a wireless charger, first check whether the product has passed the QI certification mark. Generally speaking, the quality of products certified by QI is more reliable. Wireless charging is an emerging technology of air transmission, and the controllability of current is more difficult than that of wired transmission, therefore, the quality requirements for the development of solutions and components are high.
Please confirm whether the receiving device supports wireless charging function and whether it supports QI wireless charging protocol (it is recommended to consult the equipment manufacturerIf your device is not QI certified, there may be compatibility problems, it is recommended to use the wireless charger that comes with the device to charge. Note: QI certification is the WPC Wireless Charging Alliance (Wireless Power Consortium) recognized authorization mark, products certified by the WPC alliance can use QI certification mark.
2, CE certification is a compulsory certification of the European Union, CE is the abbreviation of the French "European Community European Conformity", CE certification it is a safety sign, whether it is the production of EU member States or otherProducts produced by non-members must bear the CE mark before they can be sold in the EU market.
3, non-notified body certificate, CE certification is only the safety certification of the product, not the product quality certification, so the domestic qualified certification body can also issue CE certification, this certificate is suitable for small enterprises that do not often export or do not export demand only brand promotion enterprises. CE certification provides a unified technical specification for national products to trade in the European market and simplifies trade procedures.
4, but the short-range wireless transmission channel of most smart phones has been replaced by BluetoothThe infrared. The lack of infrared function also prevents the iPhone from using remote control software such as air conditioning TV. However, there are external infrared emitters on the market that can be plugged into the headphone jack to work with the software. Infrared disadvantages: However, the power consumption of mobile phone infrared is very large, far more than Bluetooth.
5, What is CE certification? CE certification is the EU's safety certification mark, not a quality certification mark, the main role is to ensure that people, animals and goods are not endangered. How to determine whether the product meets the EU CE certification safety indicators? It is detected according to the detection standard under the corresponding instruction. <6, Bluetooth devices must be able to recognize each other, and through the installation of appropriate software to recognize each other's support for high-level functions. Interoperability requires the same application layer protocol stack. Different types of Bluetooth devices have different requirements for compatibility, and users cannot expect the headset to contain an address book.
1, Qi certification: the universal language of Wireless charging industry Qi, the full name of wireless charging alliance (WirelessThe work of the Power Consortium (WPC), which defines a universal standard for wireless charging. This standard is "convenient" and "universal" as the core, ensuring that different brands of products only need to have the Qi logo, can be seamlessly connected with any QI-compatible wireless charger.
2, during the test, the receiver needs to establish communication with the transmitter in a short period of time, and charge steadily for 5 minutes under the condition of low battery power. This high-standard test undoubtedly improves the market competitiveness and user trust of Qi certified products. The value of Qi certification certificateA wireless charger certified by Qi not only has high quality performance, but also means that it meets internationally recognized technical specifications and can be widely accepted worldwide.
3, QI wireless charging is required to do the RED directive, the EU CE certification has a special test standard for wireless charging equipment, the test standard is EN 303 417 V1. Deep light standard.
4, but wireless charging can not be transmitted as far as WiFi for the time being, and now mature solutions can only achieve wireless charging within a distance of 10mm, generally 3~5mThe distance of about m is better, and this kind of wireless charging technology uses magnetic induction wireless charging technology. Wireless charging requires a transmitter and a receiver. The transmitter is the wireless charger, the receiver is the mobile phone and so on. There is a coil at the transmitting end and a coil at the receiving end.
5, Qi certification. At present, the electronic products that support wireless charging mostly use the Qi standard, and more than 90 mobile phones including Apple, Samsung and Nokia have passed the Qi standard certification. Products certified by the WPC Alliance will have a LOGO with the word "Qi", which means chargingThe device has been tested and is safe and Qi compliant. In order to be able to use the equipment normally and eliminate safety risks, please use wireless charging accessories with Qi certification.
6, QI is not required, CE is a mandatory requirement. But exports to Europe are generally relatively high-end, can do a QI recognition will be higher.
