Exhaust cooling fan - The machine has a built-in 3cm cooling fan, which adopts an air-extracting structure, with air in the front and air out from the back, which can effectively prevent equipment damage caused by overheating. And the fan noise is extremely low, probably within 35 decibels. The fan can also be set to be normally on or off. 3-way buck and 1-way boost design - This module mainly adopts 3 channels of sw3518s buck channel of pl5501+sw2305 boost design, each channel supports fast charge output up to 20v5a (usb-a above sw3518 and type-c below are one channel, one channel cannot be up and down at the same time output. PL5501 only has type-c interface). The main control part adopts AT32F415CBT7 microcontroller. 1.54inch IPS display - The display is a 1.54-inch ips screen. The can display the real-time data of each output. Including voltage, current, power, power and fast charging protocol. in addition, the current and voltage curve parameters of each channel can also be displayed individually. Three-way desktop fast charging module - IPS display, Built-in cooling fan, Supports almost all mainstream protocols. Small body big power - Compared with the 4-way step-down fast charging module, this product is more compact and smaller than a box of cigarettes. And the boost function can raise 12v to 20v, which is suitable for car use., Manufacturer: Akfldms
