Product Specifications:

PD+ Flash Charge+ Super Fast Charge+ Fast Charge Edition

Output Power: 22.5W

USB Output: 5V/3A, 9V/2A, 12V/1.5A (Multi-port simultaneous output limited to 5V)

IN Input: 5V/2A

Type-C Output: 5V/3A, 9V/2A, 12V/1.5A (Output only when PD protocol is supported)

Type-C Input: 5V/3A, 9V/2A, 12V/1.5A

Additional Features: Long press to activate LED indicator; Reverse insertion protection (spring-loaded positive/negative terminals prevent damage)

Operating Voltage Range: 3.3V-4.15V (Spring-loaded design with voltage drop)

Capacity requirement: Minimum actual battery pack capacity must not fall below 10,000mAh; otherwise, the device may cease discharging before the displayed charge level is fully depleted.

If proprietary device protocols are unsupported (USB without fast charging), PD charging (via Type-C output) may be employed. PD public protocols deliver more stable output.

Fast charging specifications (supported protocols):

Integrated SCP 22.5W Super Fast Charging output protocol

Integrated 22.5W Flash Charge output protocol

Integrated QC4.0+/QC4.0/QC3.0/QC2.0 output fast charging protocols

Integrated FCP, AFC input/output fast charging protocols

Supports PPS, PE2.0, SFCP output fast charging

Supports PD3.0/2.0, PE1.1 input/output protocols

Important Notes:

This product is exclusively compatible with 21700 flat-top batteries operating within a voltage range of 3.5V to 4.2V. Batteries exceeding two years of age or having undergone over 300 charge cycles will exhibit significantly reduced durability. Should charging become intermittent, lasting merely minutes or a dozen minutes without fully charging a mobile device, this indicates battery failure due to substandard performance caused by diminished rate capability. Furthermore, the product does not support modification or soldering. After-sales service is not provided for batteries that do not meet specifications. The mainboard incorporates a reverse-installation protection chip; incorrect insertion will not burn the mainboard. However, as the spring contacts are integrated, battery damage, short circuits, or incorrect polarity (e.g., one positive and one negative connected in series) may cause spring burnout. Upon correct reinstallation, the mainboard will function normally without damage.
