Disassembly report: redow hot bean 45W 2a2c charging tower

2023-10-24

Hot bean technology has launched a socket + CHARGER + wireless charging all-in-one socket product, with two national standard 3+2 sockets on both sides of the product, and equipped with safety doors. The front is 2a2c fast charging interface, and the top panel has built-in wireless charging, which can provide wireless charging function for mobile phones, with front USB interface, and charge multiple mobile phones at the same time.

The charging head network has got the hot bean 45W charging tower. Next, we will disassemble it to see the internal materials and workmanship.

The multi-in-one module launched by hot bean technology has the functions of usb-c fast charging, AC power supply and wireless charging, and has two national standard 3+2 sockets, which is convenient for expanding AC power supply and charging portable devices to meet a variety of use scenarios. Hot beans also launched a number of accessories products simultaneously, using magnetic attraction wireless charging power supply, which has higher flexibility and improves the competitiveness of products.

According to the disassembly of the charging head network, the 45W charging tower of hot beans adopts the Biyi micro encapsulated gallium nitride fast charging scheme, with built-in kp22066 encapsulated gallium nitride chip and kp4060 synchronous rectifier controller to fix the voltage output. The output adopts two-way secondary step-down circuit, of which Zhirong sw3556 corresponds to two-way usb-c output, and Chengxin micro cx8825 supplies power for usb-a port.

There is also a wireless charging module on the top of the charging tower, which is controlled by the hot bean master chip. The driver is integrated inside the chip, which has a high degree of integration. It also supports wireless power supply and can be used with a variety of accessories. Emerald electrolytic capacitor and Yubang solid-state capacitor are used for filtering inside the charging tower. The materials are well-known brands, with compact design and practical functions.
