Disassembly report: Kexun 15W magnetic wireless charger

Shenzhen Kexun Industrial Co., Ltd., founded in 1992, is a high-tech enterprise integrating R & D, production and sales. Facing the fierce Gan fast charging and 20W Mini charging market, Kexun has launched 65W 1a1c Gan fast charging charger and mini 20W PD fast charging charger for customers to choose from.

In addition to detonating the 20W fast charging market, the iPhone 12 also has a great impact on wireless charging. Therefore, Kexun recently launched a 15W magnetic wireless charger. The product comes with a 1m long usb-c input cable. The size of the charging board is the same as that of apple MagSafe magnetic wireless charger. It can firmly absorb the iPhone 12, so it can get a little experience different from Apple magnetic wireless charger. Next, the charging head network will disassemble this product to see how it is doing.

Product parameters and certification information are printed on the back.

The wireless charger is fixed and protected by a plastic tray. In addition, there is an instruction manual. This wireless charger comes with usb-c input cable. The top surface is made of plastic plate, and the bright surface is very smooth. There is a circle of divergent blue dots in the center.

The bottom and edge of the charging board are made of aluminum alloy shell, and the bottom is engraved with Kosun brand and product parameters

Model: 520003

Input: 5v3a, 9v2.22a

Output: 5W, 7.5W, 10W, 15W

Manufacturer: Shenzhen Kexun Industrial Co., Ltd

The products have passed CE, FCC and ROHS certification.

The edge of the charging board is chamfered, and the junction of the cable and the power bank is anti bending.

The whole cable is about 1 meter long.

The diameter of the charging board measured by vernier caliper is 57.95mm.

The thickness is 7.04mm. Charging board and a dollar coin size intuitive contrast. The whole wireless charging in the hands of intuitive feeling. The total weight is about 53g. The wireless charger can be adsorbed close to the iPhone 12 pro, and even the mobile phone can be easily lifted without sliding, so the adsorption is very firm. Finally, the charging test, through the chargerlab power-z km001c measured wireless charging input power is 9V 0.71a 6.4w.

The charging board is disassembled, and the contact surface between the PCB board and the fuselage shell is pasted with double-sided adhesive tape

The metal shell is provided with a positioning board for fixing the PCB board. Tear off the double-sided tape and glue the wire, coil and capacitor welding. On the other side, there is the word "hongrishengwei technology" printed on the wireless charging magnetic chip. The main control chip of wireless charging adopts the British chip ip6808. This is a wireless charging transmitter control SOC chip, compatible with the latest WPC Qi v1.2.4 standard, support a11 coil, support 5W, apple 7.5W, Samsung 10W wireless charging. Ip6808 is integrated with full bridge drive circuit and voltage & current two-way ask communication demodulation module, which has high integration and effectively helps to reduce the size of the scheme and the cost of BOM.

Summary of dismantling charging head net

The charging board of Kexun's magnetic wireless charger is small and flat, with bright plastic plate on the top, blue pattern decoration and edge chamfer design, which makes it look very delicate. Wireless charger supports 5v3a and 9v2.22a input, and 20W PD fast charger on the market can supply power for it. In addition, it supports 5W, 7.5W, 10W and 15W output to meet the wireless charging needs of apple, Samsung and other brands.

Through the disassembly of the charging head network, we know that the wireless charging master chip adopts the British chip ip6808, which is highly integrated, and can effectively simplify the peripheral circuit and reduce the cost. In addition, the wireless aluminum alloy metal shell is also provided with an annular positioning board for fixing the PCB board. In addition, the plastic plate on the top is pasted with double-sided adhesive tape, and the edge is equipped with double-layer arc magnets, up to 14 in total. Therefore, the iPhone 12 can be firmly absorbed, and there is no need to worry about falling off when filling and playing.
