Domestic programs have bee electronics, Printec, New Jet and so on. Bee electronics have done fast and slow charging for many years, and the launch scheme is relatively complete. Printec mainly does more mobile power and wireless charging schemes. New Jie this 2 years to do, mainly out to receive more cards. There are some just come in, many companies are guerrilla, do half a year to delist. To see if the company's plan is OK, it is very important to have Qi certification.
Qi wireless charging standard includes interface, performance and methodThree aspects, this will be a considerable challenge to the popularity of wireless charging technology, so through the Qi standard mobile phones will be able to wireless charge through any QI-certified charging base stations, bases or other rechargeable devices. Qi's first advance requirement for the device is not higher than 5 watts, which may be a major limitation for some manufacturers who want laptops to be able to do the same through wireless charging technology.
1, Fast charging: MagSafe wireless charging supports up to 15W fast charging, which can provide faster charging speed for iphones, AirPods and other wireless charging devices that support the Qi protocol. FOD (overheat protection) : MagSafe wireless charger also has FOD (overheat protection) function, when there is a metal foreign body detected above, the output power will be directly limited to about 0.3A, after a certain period of direct protection stop charging, at this time the phone does not charge.
2, function difference Magsafe charging box is designed to support Magsafe magneticTech-savvy device design, such as the iPhone. It utilizes powerful magnetic technology to ensure that the device firmly adsorbs and charges quickly in the charging box. In addition, Magsafe charging cases are generally more compatible and can provide charging support for other accessories such as headphones. The wireless charging box uses wireless technology to charge all the devices that support wireless charging, and has the characteristics of strong universality.
3, it not only supports wireless charging and lightning interface charging, but also is particularly compatible with the charging function of magsafe charger, bringing 15W efficient charging experience to users. magsafeGo to the app "Settings" icon and tap to enter the new interface. ; Then, after entering the Settings operation interface, find the "other Settings" option and click on it. ; After entering the other Settings operation screen, find the "Developer options" option and click on it.
Turn on your phone and tap Settings. On the Settings screen, tap Battery. Just turn on the flash charge in both engines. oppo mobile VOOC Flash Charge Introduction VOOC Flash charge is a low voltage fast charging technology developed by OPPO with 18 patents. It uses low voltage and high current mode to ensure charging speed and reduce mobile phone chargingPower hour adapter and mobile phone heating conditions.
Turn on your phone and tap Settings. On the Settings screen, tap Battery. Just turn on the flash charge in both engines. The VOOC flash charge is the first to be used on OPPO Find 7. As the use of 3000 mah battery OPPO Find 7, using VOOC flash charge, charging 5 minutes can make a call for 2 hours, 30 minutes of mobile phone power can be directly charged to 75%, which is enough power for most people to use for a whole day.
1, the AP45851 uses a unique "CNS-chip as system" technology to fully integrate a variety of high-performance mixed-signal functions, such as low-power device detection during standby and foreign object detection (FOD) for secure wireless charging. The high level of integration and advanced features help simplify the system design of application engineers, and the periphery is extremely simple, while greatly reducing the difficulty of PCB design.
2, wireless charger refers to the use of electromagnetic wave induction principle for charging equipment, the principle is similar to a transformer. There is a coil in the sending end and the receiving end. The sending end coil is connected to the wired power supply to generate an electromagnetic signal, and the receiving end coil senses the electromagnetic signal of the sending end to generate a current to charge the battery.
3, the mobile phone and the wireless charger are arranged at both ends of the receiving/transmitting coil, the wireless charger current through the transmitting coil to generate a magnetic field, the mobile phone receiving coil close to the magnetic field will generate current, and then through the mobile phone built-in rectifier voltage regulator filter circuit into usable DC DC. Well, noIt's a bit of a headache just looking at the principle.
