400W 4-Way Full Protocol Desktop Charger PD+QC3.0 SW3518 Buck Module with 1.54" IPS Screen Display

Read Before Purchasing:
1. This product is a step-down fast charging module. If 20v is required to charge notebook devices, a 24v power supply is required. If the output of 20v is not usually used, other low-voltage power supplies can be used for power supply. We recommend that a 24v power supply be used all the time, and the cost has not changed.
2. This product supports a maximum output of 400w, provided that your power supply has enough power (the main unit does not have a power supply). But from the actual use situation, few buyers need such a large power output, so we suggest that a 100-200w 24v power supply is enough.

Features:
4-Way Buck Design
This module adopts 4-channel step-down design. It can output 24V and output 5-20V. Each channel supports fast charge output up to 20V 5A (The USB-A above and the type-C below are 1 channel, which does not support simultaneous output from upper and lower ports).

Main Control module AT32F415CBT7 MCU
The main control part adopts AT32F415CBT7 MCU, and the firmware part can be directly connected to a computer for upgrade using a type-c data cable in the later stage.

1.54" IPS Screen
The home page can display real-time data for each output, including voltage, current, power, electric quantity and fast charging protocol. In addition, it can also display the current and voltage curve parameters for each channel separately.

Extractor Cooling Fan
This unit also has a built-in 3cm/1.2" cooling fan. It adopts a pumping structure, with air inlet in the front and air outlet in the back, which can effectively prevent equipment damage caused by overheating. And the noise of the fan is extremely low, probably within 20 decibels. The fan can also be set to normally on or off mode.

Supports Three Input Interfaces
The main unit supports three input interfaces, namely XT60, DC5.5mm, and Type-C. It should be noted that the power above 200W is recommended to use XT60 power supply, which can effectively prevent the high-current plug from overheating. If Type-C power supply is used, the power supply device needs to support 20V and an output capability of above 5A.

Supports Almost All Major Protocols
The fast charging protocol of this product basically covers all types of electronic products on the market.

Compact Size
Smaller than a cellphone, making it easier to carry.
