1, currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, which uses electromagnetic waves as a medium, remains in the laboratory stage. At present, the main commercial medium on the market is magnetic fieldThe technology is divided into magnetic induction and magnetic resonance 2 technologies.
2, the core magnetic resonance long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
3, that needs to be placed next to the transmitter), at the same time, they are also studying long-distance wireless charging, which will be an emerging market. In fact, the current technology can achieve effective power transmission in the range of 3 to 4 feet, but this needs to be verified by the relevant organization. I believe that in the next 5 to 10 years, or even sooner, long-distance wireless charging will enter everyone's life.
The rated energy is less than 100Wh and can be carried on board without the approval of the airline. The rated energy is 100Wh - 160Wh and can only be carried on the aircraft after approval by the airline. The rated energy exceeds 160Wh, do not carry. Each passenger can carry a maximum of two power banks on board, and the rated energy cannot exceed 160Wh. The power bank can only be carried on the person, not allowed to check. Power bank noCan be checked, only carry-on or portable.
Aircraft charging bank carrying regulations, it is not allowed to carry the rated energy of more than 160Wh charging bank. Power banks with rated energy less than 100Wh can be carried on the plane. Power banks with rated energy of more than 100Wh and less than 160Wh can be carried on board after approval by the airline. The charging treasure must have a clear and comprehensive logo, and the charging treasure has 3C certification. The charging bank can only be carried on the plane if it meets the above three conditions.
Aircraft standard requirements for power banks are as follows: Voltage and current limits: Most airlines allow the power bank to be carriedThe rated voltage and current shall not exceed the specified standards. These standards are typically 5V/2A or higher charging rates. This means that the power bank cannot provide too high a voltage or current to the electronic device, otherwise it will be banned by the airline.
C10 charging bank will mark the capacity: 7V/10000mAh, rated energy =7V multiplied by 10000mAh=37Wh, less than 100Wh. It meets Civil Aviation Authority regulations and can be carried on board. Similarly, the maximum output voltage of the general charging bank is 5V. According to the formula conversion, capacity = rated energy divided by voltage, 100Wh divided by 5V is equal to 20000mA, so the capacity of the power bank within 20000mA can be brought on the plane.
vivo mobile phones will be strictly tested before leaving the factory to ensure that the sold machines meet the quality standards.
Mobile phones are not fall-resistant products, and the damage caused by different falling heights and landing angles may be different.It is recommended to wear a mobile phone protective case for the mobile phone, and try to avoid causing the mobile phone to slip during the normal use of the mobile phone.
Hello! Can your mobile phone work normally? If your mobile phone can not be used normally, it is recommended that you take your mobile phone to the local after-sales testing and processing, after-sales technicians will deal with it for you.
The height of the fall is determined according to the weight of the product, divided into 90cm, 76cm, 65cm several grades. 0.45~54kg: 720cm; 55~163kg: 60.96cm; 164~272kg: 472cm; 273~445kg: 30.48cm. There are special standards for the fall test countries, and the fall mode is one corner, three sides, six sides of free fall.
Hello! vivo mobile phone is very good oh, it is recommended that you use the mobile phone protective case to protect the mobile phone, so as not to break it. Please feel free to contact us if you have any questions.
If the mobile phone fall is more serious, you can go to our vivo customer service center test. Mobile phone falls and breaks do not belong to the scope of warranty, can not be repaired and can not be replaced with a new machine. Enter vivo official website app-- Service -- my service -- serviceThe service outlet can query the address and phone number of the nearest customer service outlet. Tips: Before you go to the customer service center, call to confirm whether the customer service center is working normally to avoid a trip in vain.
