22.5W Power Bank Bidirectional Fast Charging Power Module (Only Type-C)

Description

Fast-Charging Protocol Support:

Supports full mainstream fast-charging protocols.

Charging current up to 5A, efficiency up to 96%, output power up to 22.5W (≈95% efficiency).

Automatic load detection and light-load detection.

Supports digital tube display and LED indicators.

Built-in protection: overcurrent, short-circuit, charging timeout, overvoltage.

Supported Protocol List:

• PPS / PD3.0 / PD2.0

• QC4+ / QC4 / QC3.0 / QC2.0

• VOOC / DASH / Warp

• Samsung AFC

• Huawei FCP, SCP (5V4.5A / 4.5V1.5A), HSCP

• MediaTek PE2.0 / PE1.1

• SFCP

 

Battery charging supports: 

PD3.0 / PD2.0, AFC, FCP, SCP, PE1.1

 

Product Design & Build:

• Compact size with strong performance.

• High-quality materials and optimized PCB design.

• Delivers high efficiency in a small footprint.

• High-power operation may generate heat — normal and safe.

• Board thickness: 6 mm, 8.5 mm with display.

 

Usage Notes:

Voltage Checking

• After wiring, check with a multimeter to ensure B+ and B- voltages match during charging/discharging.

• Large differences indicate wiring issues or battery aging.

 

Function Key:

• Single press – Enable Type-C output and show battery level.

• Double press – Close the Type-C output and battery display.

• If external power is present, only the output is turned off.

 

Ports:

Type-C: Supports input & output.

B+: Must be soldered with thick, short wiring.

B-: Same requirement — thick, short, soldered.

 

Important Precautions Before Use:

• Connect a charger first to verify LED indicators before assembling.

•Do not connect a battery before confirming LED status.

• Battery & Wiring Requirements

• Battery must be soldered, not twisted.

• Wrong polarity will burn the board.

• Wires must be thick and short for proper current delivery.

• Fast-charging version requires 10A, standard version 7A.

• Batteries must be connected in parallel only, not series.

• Only use a 3.7V lithium battery.

Battery Condition:

Aged batteries can cause incorrect charging or inability to discharge.

If the battery has a protection board, ensure it supports:

>7A (standard)

>10A (fast charge)

Otherwise remove it.

Reverse Connection Warning:

• Reverse polarity always burns the protection ICs and leaves visible marks.

Damage from reverse connection is not covered.

Heat Generation:

• All power modules generate heat — this is normal.

• High-quality ICs ensure safety and long life

Coulomb Meter Notes:

• Battery level may be inaccurate right after wiring.

• Accuracy improves after several full charge/discharge cycles.

Protocol Compatibility Note:

Phone protocols change over time.

Example: older Honor phones supported 5V4.5A SCP, newer ones use 10V2.5A SCP.

→ Always follow the protocol list printed on the board.
