Disassembly report: Ruiliang Mini 33W GaN Charger

2024-03-21

With the release of Apple's 14 series mobile phones, a new wave of mini fast charging boom has been brought. Remax Remax launched a dual port 33W fast charging of ice crystal series. This charger adopts a small square design and supports USB-C and USB-A quick charging. It can quickly charge mainstream mobile phones and laptops. The USB-A port can also charge older devices, with better compatibility.

This charger is made of translucent shell, and its appearance design is very distinctive. With the help of GaN devices, the charger is compact and easy to carry. The charging head network will disassemble this charger in detail to see how the internal design and materials are used.

The charging head network has also disassembled the REMAX 20W PD fast charging charger, REMAX 20W 1A1C fast charging charger, REMAX mini 30W gallium nitride fast charging charger, REMAX 65W PD fast charging gallium nitride charger, REMAX 65W 1A1C fast charging charger and other products before. Welcome to check.

This 33W GaN charger adopts a double shell design. The combination of transparent and semi transparent shells makes it possible to see the internal components of the charger and has a very unique appearance. The charger is equipped with a shaped core GaN device, which is small and portable. The charger has 1A1C interface, supports 5~20V full voltage range and PPS fast charging, which can meet the fast charging requirements of Android mobile phones and laptops.

Through disassembly, the charging head network learned that this charger uses two PCBs for combined welding, making full use of the internal space. The charger uses Maorui core MK2697A gallium nitride master chip and concentrated energy core CGK65R400B gallium nitride power device to provide a wide output range, high-efficient gallium nitride fast charging power supply solution. The output adopts the silicon cloud semiconductor XPD738 protocol chip, with high integration. The charger is internally sealed with transparent glue, which can improve the heat dissipation performance. Compact interior design, high space utilization.
