Fast-Charging Solder-Free 3-Cell 18650 Power Bank Kit Removable Power Bank Case, Batteries Not Included(Blue)

1. USB Output: 5V/3A, 9V/2.5A, 12V/1.87A (Only 5V is available when multiple ports are in use simultaneously)
2. IN Input (micro): 5V/3A, 9V/2A
3. Type-C Output: 5V/3A, 9V/2.22A, 12V/1.67A (Output available only when PD protocol is supported)
4. Type-C Input: 5V/3A, 9V/2A, 12V/1.5A (Supports 5V charging while discharging)
5. QC: 18W; PD: 20W; SCP: 22.5W
6. Other Features: On the fast-charging version, press and hold the button for 3 seconds to enable low-current mode; double-tap to disable total output
7. Battery Type: 3 x 3.7V 18650 batteries (flat-top, no protection board, internal resistance below 40 mΩ, 1C discharge rate, voltage per cell must be between 3.3–4.2V). Do not use pointed-top batteries; modifications or the use of other non-compliant batteries are not supported! )
8. Operating Voltage: 3.3V-4.15V (note: the spring causes a voltage drop)
9. Battery Level Indicator: 4-level LED display; automatically powers off when not in use. Note: Battery level is calculated based on voltage; please use high-performance batteries with stable voltage. If the battery quality is too poor, the voltage drop will be excessive, causing the battery level indicator to deplete rapidly; the output will remain at the first or second battery level almost all the time.
10. Charging Specifications: Supports 18W charging; current is automatically adjusted at the battery end, with a charging current of up to 5A.
11. Discharge Specifications: Output current capabilities: 5V/3A, 9V/2.22A, 12V/1.67A
12. 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
13. Dimensions: Approx. 9.5 x 6.9 x 2.2 cm

Fast Charging Specifications (Supported Protocols):
1. Supports 5V, 9V, and 12V input/output voltage levels;
2. Compatible with BC1.2, Compatible with Apple, and Compatible with Samsung smartphone fast charging;
3. Integrates for Huawei SCP 22.5W Super Fast Charging output protocol;
4. Integrates QC 2.0/QC 3.0 output fast charging protocols;
5. Integrates FCP and AFC input/output fast charging protocols
6. Integrated USB-C DRP protocol, supporting fast charging input/output;
7. Integrated USB Power Delivery (PD 2.0/3.0) protocol;
8. Supports PD 2.0/3.0 input/output protocols

Note:
1. Compatible batteries: 18650 lithium-ion batteries (flat-top, without a protection circuit)
2. Battery connection requirements: 3.3-4.2V lithium-ion batteries (18650 lithium-ion batteries); do not connect other types of batteries, such as 1.2V 18650 NiMH batteries, 3.2V lithium iron phosphate batteries, any dry cell batteries, or 12V lead-acid batteries
3. The 3-cell configuration can accommodate up to 3 18650 batteries (2 or 1 battery can also be used)
4. Charging Input Requirements: A charger rated at 5V/2A or higher is best suited; however, any other 5V constant-voltage power source can be used as the charging input
5. After connecting the batteries, the circuit board typically requires a brief charge to activate before output is available. If the power bank has not been used for an extended period, the output will shut off and must be reactivated
6. Kit Contents: Housing + boost board (no batteries included); does not include batteries or a charging cable
7. Although this portable power bank can charge most smartphone models, it is not universally compatible; it does not support every single model or variant.
8. If there is no output after powering on for the first time, you will need to apply a 5V voltage to the charging port to activate it.
9. The contact pad is the positive terminal, and the spring is the negative terminal. Please insert them correctly; do not reverse the polarity, or the spring will burn out, damaging the product!
