Transparent 4-Port 22.5W Fast Power Bank Solder-Free 4-Cell 21700 Battery Case Portable PD Battery Storage Box with OutdoorLight

Output Power: 22.5W (Peak 27W)

USB Output: 5V/4.5A (VOOC), 9V/2.5A, 12V/1.87A (Multi-port simultaneous output limited to 5V);

IN Input (Lightning): 5V/2A;

Type-C Output: 5V/3.1A, 9V/2.22A, 12V/1.67A (output only when PD protocol is supported);

Type-C Input: 5V/3A, 9V/2A, 12V/1.5A (does not support simultaneous input);

Additional Features: Long press to activate LED indicator

Colors: Black, Orange

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

Capacity Requirement: Battery pack’s minimum actual capacity must not fall below 10,000mAh. Otherwise, the battery may become unable to discharge fully even when the displayed charge level indicates otherwise.

Note: If proprietary phone protocols are unsupported (USB lacks fast charging), use PD charging (TYPE-C output) for more stable output via the PD public protocol.

Fast Charging Specifications (Supported Protocols):

With data-enabled charging cable, successful communication handshake requires one of the following protocols:

Supports 5V, 9V, 12V voltage levels for input/output;

Compatible with BC1.2, Apple, and Samsung fast charging

Integrated Huawei SCP 25W SuperCharge output protocol;

Integrated OPPO VOOC 22.5W Flash Charge output protocol;

Integrated QC 2.0/QC 3.0 Qualcomm output fast charging protocol;

Integrated FCP (Huawei) and AFC (Samsung) input/output fast charging protocols;

Integrated USB-C DRP protocol, supporting input/output fast charging;

Integrated USB Power Delivery (PD 2.0/3.0) protocol

Supports PD 2.0/3.0 input/output

Charging Specifications:

Supports 18W charging with automatic battery-side current regulation, achieving up to 5A charging current.

For initial charge, recommend charging to 100% followed by several additional hours to fully balance the battery.

Discharging Specifications:

Output current capability: 5V/3.1A; 9V/2.22A; 12V/1.67A

Supports line compensation; synchronous switch discharge at 5V/2A achieves over 95% efficiency

Multiple protections, high reliability:

Built-in input overvoltage and undervoltage protection; integrated output overcurrent, overvoltage, and short-circuit protection; built-in battery overcharge, over-discharge, and overcurrent protection; built-in IC overtemperature protection;

Note:

This product only supports 21700 (21x70mm) or 20650 (20x65mm) batteries with voltages between 3.5V-4.2V. Batteries over two years old or with over 300 charge cycles typically exhibit poor durability. Symptoms include intermittent charging, short runtime (minutes to tens of minutes), or inability to fully charge a phone—all indicating severely degraded battery performance. Additionally, the product does not support modification or soldering. After-sales service is not provided for issues arising from non-compliant batteries. The mainboard incorporates a reverse-installation protection chip. While installing batteries backwards will not burn the mainboard, the integrated spring contacts may be damaged if the battery casing is punctured, short-circuited, or connected in series (one positive, one negative). However, after correcting the installation, the mainboard will remain fully functional and will not burn out.
