1. Support up to 22.5W output power and 5A charging current, compatible with a variety of fast charging protocols (such as PD, QC, SCP, etc.), significantly improve charging efficiency. 2. Built-in intelligent chip, automatically recognizes the device type and matches the optimal charging protocol, adapting to the fast charging needs of mainstream of cell phones and devices. 3. Adopting high-quality electronic components, the charging efficiency is as high as 95%-96%, which ensures stable operation for a long time and prolongs the service life of the product. 4. With multiple safety protection mechanisms, including over-current, short-circuit, over-voltage, charging timeout protection, etc., to fully protect the use of safety. 5. Modular and compact design, convenient for DIY users to flexibly integrate into various mobile power shells, easy to carry, strong applicability. Parameter: Charging current up to 5A (battery side), efficiency up to 96% Output power up to 22.5W, efficiency up to 95% Supports /PD3.0/PD2.0 Supports QC4+/QC4/QC3.0/QC2.0 Supports AFC Supports FCP, SCP Supports FCP, SCP, HSCP Supports PE2.0/PE1.1 Supports SFCP Charge the battery Support PD3.0/PD2.0, AFCFCP, SCP, PE1.1 Module input interface: Key: short action, open the USB port and light load Type-C output port external discharge and power display. When double-click action, close the USB port and Type-C output port and power display; if there is an external power supply present, only the output port be closed. Type-c port: support input and output USB port: high-current output interface B+: battery positive interface, the use of must be welded, must be thick, can not be too long B-: battery negative interface, the use of must be welded, must be thick, can not be too long module wiring with a multimeter to measure the module charging and discharging when the voltage of the B+ and B- contacts are the same or the difference is very small, if the difference is large, then there are wiring problems or battery aging. Problems or battery aging use. Specification:B:Digital display Color:Black Material:PCB Package Contents: 1 * Display 22.5W Power Bank Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
