1, green magnetic wireless charging mobile power supplyDisassemble the fuselage shell, the edge of the buckle package. The PCB board is fixed with screws, the wireless charging coil is fixed on the battery core, and is covered with foam protection. A thermistor is fixed on one side for temperature monitoring. Take out the PCB board and electric core, the body shell is affixed with protective foam, the corresponding circuit board and electric core junction is provided with an isolation board.
2, Green Link MFi certified 10000mAh two-way fast charge mobile power supply This mobile power supply stands out with its exquisite design. It is made of PC flame retardant material, the shell lines are rounded, and the laser engraving texture adds a touch of technology, UGREEN's brand Logo stood proudly. There are four LED power indicators on the front, which are clear and intuitive, and the power button on the side is convenient to operate. The Lightning output line is cleverly designed and stored in the internal cable slot, which is practical and neat.
3, the power absorption treasure is a magnetic charging treasure and magnetic charger, such as green link's magnetic charging treasure is good. Green Link Three-in-one MagSafe magnetic wireless charging Bank is a three-in-one MagSafe magnetic wireless charging bank, using Apple's ATL battery, providing a strong magnetic design. Of course, wireless wired dual mode fast charging design, plus can change skills2 id=' Mi 55W vertical air-cooled wireless charging disassembly, real wireless flash charging, internal work is excellent '> Mi 55W vertical air-cooled wireless charging disassembly, real wireless flash charging, internal work is excellent
Millet 55W vertical air-cooled wireless charging using PC flame retardant material plastic shell, fuselage edge clear end Angle arc transition, support board is black, base sandblasting treatment is gold. From the front, the front end of the base is equipped with LED indicators, and the support board is layered above and below, using different designs. Indicator light is green when working.
Conclusion: Millet vertical air-cooled wireless charger with its small size,The feature of large output has been the highlight of my recent purchase. The following is an intuitive introduction to this product: Unpacking experience: / Millet vertical air-cooled wireless charging 30W in white transparent plastic packaging, visible at a glance. Its simple and generous orange-red packaging box contains the main body, data cable, charging head and manual, reflecting the efficient style of Xiaomi.
Compared with the common 10W wireless charging technology on the market, Xiaomi's 30W wireless flash charge can charge half of the 4000mAh battery in 25 minutes, achieving the efficiency of "wireless beyond wired". Millet vertical air cooled wireless chargeThe 30W design is clever, the Angle is ergonomic, convenient for users to operate while charging, and the built-in ultra-quiet fan can effectively actively dissipate heat, improving the comfort of the charging process.
Wireless charging PCB, different functions, the required components are different. The required components are: resistor, capacitor, resonant capacitor, resonant coil, MOS tube, control chip, protocol chip.
Control chip: Manages the entire wireless chargingProcess, including voltage regulation, power control, communication and other functions. Power amplifier (PA) : Increases signal strength in order to transmit energy efficiently. Oscillators and modulators: Generate high-frequency AC signals for wireless transmission. Coils: Used to generate or receive electromagnetic fields, are a key part of wireless charging.
The transmitting end is the wireless charger, and the receiving end is the mobile phone. There is a coil at the transmitting end and a coil at the receiving end. The transmitting end transmits energy through the control board and coil, and the receiving end receives energy through the control board and coil, so that wireless charging can be achieved. Samsung S6 pictured belowMobile phone and Polopai technology wireless charging mobile power charging situation, the phone can be placed on the wireless charger to start charging, no need to connect through the USB port charging.
Single-layer board: that is, only one side of the board is coated with copper and the other side is not coated with copper. Usually the components are placed on the side without copper, and the side with copper is mainly used for wiring and welding. (2) Double-layer board: that is, a circuit board with copper on both sides, usually called the Top Layer on one side and the Bottom Layer on the other. Generally, the top layer is used as the component surface, and the bottom layer is used as the component welding surface.
Copper foil surface: The copper foil surface is the main body of the PCB, which is composed of a bare pad and a copper foil circuit covered by green oil, and the pad is used for welding components. Solder block layer: Used to protect copper foil circuits, made of high temperature solder block. Character layer: used to mark the number and symbol of the components to facilitate circuit identification during PCB processing.
