21 years of age to do and should not do Mobile phones and other equipment as long as labeled receive coil, placed in the "the mouse pad" on any place can be charging, not like some previous technology that need accurate location. Several equipment and put on cushion, can simultaneously charging. usb charger The charger is very weak magnetic fields produced, able to charge but will not affect equipment near the credit card, such as video using magnetic recording of data items.Wireless charging spoken parts in an opera is the use of the principle of electromagnetic induction charging, no new technology. solar led light I bought the home more than 10 years ago on electric toothbrush with philips, toothbrush in a charging a can, he that so-called invention in the past but on the basis of the study more practical some. iphone solar charger Prospects: the technology is the principle of electromagnetic field to create a parallel micro charging, apart from the principle of complex don't talk, the user need only will charge equipment in a "flat" can be carried out on charging as charge method in the past had appeared. Ipad charger As I know this kind of thing was not as high technical content, is the simple ac induction technology, the launch and JieShouDuan corresponding coil to send and receive current signal (of course in the receiving device is not large space design add the receiver or need to the next point kung fu); iphone charger So this certainly exist radiation problems; But the different equipment need different the receiver, use rise is not convenient; Price is not low. Meet China mobile phone chargers standard interface design techniquesThis paper describes the latest China industry standard YD/T1591-2006 and USB2. solar laptop charger 0 specification of cell phone battery chargers and interface of lithium requirements, and introduced how to use the power of the Maxim channel management IC MAX8606 to meet YD/T1591-2006 and USB2.0 requirements. Learn Chinese China has in on December 14, has issued a new industry standard YD/T1591-2006, namely the mobile communications terminal equipment charger and interface technology requirements and testing methods. learn chinese online Making such a standard cell phone because the purpose of renewal and change the frequency of the mobile phone consumers more and more quick, and different cell phone chargers technical indicators and interface is different, can't exchange use, consumers change from old cell phone charger waste. speaking chinese Not only increased consumer of mobile phone use cost, still can cause environmental pollution. Through making cell phone chargers unified interface standards, making different brand, different kinds of mobile phones can share charger, when consumer is buying a new mobile phone can still use the old charger. how to speak chinese So as to reduce the use of mobile phone costs.1 YD/T1591-2006 standard new request.From the exchange adapter to the mobile phone of connections between the traditional communication is part of the adapter, as shown in figure 1 below.The industry standard in the fourth quarter requirements use period of , one aspect of the matter is the industry standard USB type A plug, used to and exchange adapter A standard USB type A socket connection.RJY
