Three-way desktop fast charging module - IPS display, Built-in cooling fan, Supports almost all mainstream protocols. 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. 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. 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. Supports almost all mainstream protocols - The fast charging protocol of this product basically covers all types of electronic products on the market. However, there are a few points to note. If a module that is not 100W is plugged into a mobile phone, it must have a charging power of 100W. The specific power is determined by the fast charging protocol, or it may be determined by the power supply. Some manufacturers, such as for and for , will detect whether the charging device is for-original. If it is not-original chip or charging , it cannot reach the highest power. At the same time, the fast charging cable of the data cable used by the device is also very important. For example, the data cable that does not supporte-mark naturally cannot obtain the maximum power.
