Three-Way Buck-Boost Desktop Fast Charging Module 300w High Power, 1.54inch IPS Display, 12v to 20v Boost

Design and power: This desktop fast charging module uses a 3-way buck plus 1-way boost topology. It employs three sw3518s buck channels together with a pl5501+sw2305 boost stage. Each channel can deliver fast-charge output up to 20v5a (note: USB-A above sw3518 and Type-C below share one channel; a single channel cannot output both up and down at the same time). PL5501 only has type-c interface. The module is controlled by an AT32F415CBT7 microcontroller and provides 300w high power in a compact package — more compact than a comparable 4-way step-down fast charging module and ideal where space is limited. Display and monitoring: A 1.54inch IPS screen gives real-time readouts for each output. The display shows voltage, current, power and fast-charging protocol information, and it can present individual current and voltage curve parameters per channel for detailed monitoring. Boost and use case: The built-in boost function can raise 12v to 20v, making the module suitable for automotive applications and other 12v systems that require higher-voltage fast charging. Cooling and protocols: Cooling is handled by a built-in 3cm exhaust fan using an air-extracting layout (air in at the front, air out at the back) to reduce overheating risk. Fan noise is very low — probably within 35 decibels. The fan can also be set to be normally on or . The unit supports almost all mainstream fast-charging protocols, delivering versatile charging options in a small desktop form factor.
