1. Supports PD3.1 protocol and provides fast charging power of up to 140W. Compact and , easy to carry, suitable for outdoor and mobile use. 2. Equipped with an efficient Type-C interface, supporting bidirectional fast charging and data transmission. Support high current charging and discharging to meet the needs of high-performance devices. 3. Automatically identify battery status, dynamically adjust charging current, safety and speed. 4. Fast charging specifications: Integrated FCP input/output fast charging protocol, Integrated AFC input/output fast charging protocol, Integrated SCP input/output fast charging protocol, Integrated PD3.1 Input/Output Fast Charging Protocol, Integrated QC2.0/QC3.0/QC3.0+input/output fast charging protocol. Socket type: XT30PW-M matters needing attention: 1. After connecting a battery with normal voltage, the indicator light turn on, and TYPE-C can output power without activation. 2. Inspection method after receiving: Do not connect the battery, connect the TYPE-C interface to the charger. Measure the voltage on the battery pad after 3 seconds: 5S is 21V. If the voltage is normal, the battery can be welded and used. Before welding the wires, please disconnect the power supply from the TYPE-C port. 3. Instructions for using this module to charge batteries: Automatically identify the maximum power of the C-port power supply and charge the battery with a maximum power of 140W. Adaptive battery terminal current. 4. Regarding the output performance of TYPE-C interface: When outputting 20V5A (mainly used for laptop or lithium battery charging), it is recommended to use 4S or above lithium batteries. When using 3S, significant temperature rise may occur due to high battery current. If a 140W output is required, considering the current issue at the battery end, it be used in conjunction with a 6S lithium battery.
