How to apply an external power supply
If the battery voltage is
insufficient to unlock the door
from the outside, you can use a
5V power bank as an external
power supply by connecting it
to the lock via the Type-C port.
After unlocking the door, please
replace the batteries promptly.
If the system freezes and you
Type-C port
cannot unlock the door from
the outside, you can use a 5V
power bank to power the lock.
This will automatically restart
the system.
