Fast Charging technology is a must-have feature in today's mobile phones as they come bigger capacity battery. A standard USB 2.0 port typically outputs 5V at 0.5A. Fast Charging protocols boost the voltage and/or current to a higher value to fill up the battery quicker. With the Power Delivery (PD) specification, the total output power can go higher to cater for even a demanding device such as a laptop.
This module has a 5.5mm x 2.1mm DC jack that accepts 8V to 30V DC input. You can use a spare DC power supply from old laptop or printer for example. Alternatively, there are solder pads (marked + and -) that you can use to connect your power supply. This board supports various fast charging protocols including Power Delivery PD3.1 (with PPS), Quick Charge QC3.0/2.0, Huawei FCP, Mediatek PE 2.0 and BC1.2. It is small enough to be embedded anywhere, including in a car. This is a buck controller module, so make sure that the input voltage is higher than the charging voltage supported by your device.
The output connector is USB-C and this module can output up to 65 W of power.
Additional notes:
For optimum charging time, the charging module (this board), cable and target device must support one of the fast charging protocol. The target device will negotiate with this charging module what is the best output power that can be supported. For high voltage/current charging, make sure you use a high quality charging cable with low resistance
This is a buck converter module. Power source must be higher than the intended charging output. e.g. If you want to do 20V, 3A charging, your power source must able to supply at least 21V
High charging power will cause heat. Please make sure the working area is well ventilated
If your device does not support fast charging, you will only get 5V output voltage
Technical details:
Maximum output power: 65 W (20V, 3.25A)
Input connector: DC Barrel Jack 5.1 x 2.1 mm, solder points marked as + and -
Input voltage: 8-30 V (buck converter - input must be higher than the intended output)
Output voltage: Automatically adjusted between 3.3V and 21V when connected to a compatible TYPE-C receiving device (input voltage should be higher than output voltage, e.g. if 20V fast charging is triggered, input voltage should be higher than 20V)
