Does the safe deposit box have dual power supplies?

Many modern safe deposit boxs, especially high-end or intelligent safe deposit boxs, are equipped with dual power supply designs to ensure safe deposit box and effective use in the event of a main power failure. The following is a detailed introduction to the dual power system:
1. Definition of Dual Power Supply
Main power supply: usually powered by a battery or connected to a home power adapter, used to support electronic locks or smart functions in the safe deposit box.
Backup power supply: used to provide additional power in case of main power failure (such as battery depletion or power outage), ensuring that users can still unlock.

2. Common dual power configurations
Battery+external power supply: Many safe deposit boxs are equipped with regular batteries (such as AA or 9V batteries) and can also be powered through external power sources (such as power adapters or USB ports). In this way, even if the battery is depleted, users can still unlock the lock through an external power source.
Battery+emergency battery interface: Some safe deposit boxs are designed with an emergency battery interface that allows for a short period of power supply by inserting an external battery (such as a 9V battery) when the battery is depleted, thereby activating the safe deposit box.

3. Backup function
Battery Failure Warning: Modern safe deposit boxs will issue a warning when the battery level is low, reminding users to replace the battery as soon as possible to avoid power outages.
Backup Battery: Some safe deposit boxs have a backup battery compartment where users can prepare a second set of batteries for emergency use. Usually, this backup battery compartment is designed to be compact and does not affect the appearance of the safe deposit box.

4. Advantages
Preventing battery depletion and inability to unlock: If the safe deposit box only has a single power system, once the battery is depleted or there is a problem with the power supply, it cannot be unlocked. The dual power design can avoid this situation.
Ensure the normal operation of intelligent functions: For safe deposit boxs with remote unlocking, alarm and other intelligent functions, dual power supply can ensure that these functions can continue to work even when there is a problem with the main power supply.
Increase safe deposit boxty and convenience: Users do not have to worry about not being able to open the safe deposit box in a timely manner when the battery is depleted, as the backup power supply provides additional protection.
