Lock State & Activation Instructions
When the battery is connected for the first time, no matter what the battery voltage is, the chip is in a locked state and the power light is the lowest. The bit will flash for 5 seconds as a prompt; in the non-charging state, if the battery voltage is too low to trigger a low-power shutdown, it will also enter the locked state.
When the battery is low-voltage, there is no cell phone insertion detection function, and it cannot be activated by pressing the button.
In the locked state, you must enter the charging state (plug in the charging cable) to activate the chip function.
Charging Logic & Smart Watch Priority
When the battery is less than 3V, use 200mA trickle charging; when the battery voltage is greater than 3V, enter constant current charging; when the battery voltage is close to the set battery voltage, it enters constant voltage charging; when the battery terminal charging current is less than about 400mA and the battery voltage approaches constant voltage charging, stop charging. After charging is completed, if the battery voltage is lower than 4.1V, restart battery charging.
When charging with VIN 5V input, the input power is 10W.
Supports simultaneous charging and discharging. When charging and discharging at the same time, the input and output are both 5V.
When the C port is charging the mobile phone and has switched to fast charging, the watch 3W wireless charging function is turned off by default. If you need to turn on the watch charging, press the button again to reset and activate the power bank wireless charging watch charging function. When giving priority to charging the watch, both the C port and the Apple LIHGING line default to 5V output.
Charging and discharging at the same time: When the charging power supply and electrical equipment are plugged in at the same time, it will automatically enter the charging and discharging mode. In this mode, the chip will automatically shut down the internal fast charge input request.
Connection Detection & Power Operations
Automatic Wake-up: When a mobile phone is inserted, it will wake up from standby immediately and give priority to turning on the boost 5V to charge the mobile phone. If a fast charging protocol is recognized, it will switch to fast charging after a few seconds.
Smart Phone Shutdown: When the phone is fully charged and the current is less than 80mA for 32 seconds, the product will automatically shut down.
Smart Watch Shutdown: When the watch is fully charged and not removed, the product will automatically shut down after 6 hours by default. When the watch is not fully charged and is removed, the product will automatically shut down after 32 seconds.
Turn on: Short press the button once to turn on the power display and boost output, and the product turns on.
Shut down: Short press the button twice within 1 second to turn off the boost output, power display, and shut down the product.

Frequently Asked Questions (FAQ)
How do I unlock or reactivate the chip when it enters a locked state?
To activate the chip and exit the locked state, you must plug in a charging cable to trigger the charging state.
How do I manually turn the power bank on and off?
Short press the button once to turn on the power display and start boost output. To turn it off, short press the button twice within 1 second.
What happens if I try to charge the power bank and charge a phone simultaneously?
The system will automatically enter simultaneous charging and discharging mode. Both the input and output will default to 5V, and the internal fast charge input request will be disabled.
Why does the watch wireless charging turn off when my phone uses USB-C fast charging?
By default, the 3W wireless charging for the watch turns off when fast charging is active on the USB-C port. You can manually re-activate watch charging by pressing the power button once to reset.
What are the automatic shutdown conditions for connected devices?
For phones, the device shuts down if the current drops below 80mA for 32 seconds. For a fully charged watch, it shuts down after 6 hours, or after 32 seconds if the watch is removed before completion.
What safety protections does the device feature?
It features input overvoltage/undervoltage protection, short circuit protection, and integrated IC and battery temperature loop regulation to intelligently adjust current.
