[Security] Grade AES XTS 256-bit hardware encryption. No need to worry about the safety of important files. The password is entered using physical keys, and no trace of the password entry will be left on the computer. [Compatibility] USB 3.0 supports hot swap. Compatible with operating systems such as Windows, Mac, and Android. Enables high-speed and stable data transfer. [Superiority] When the user enters the wrong password 10 times consecutively, hacker detection and protection are triggered, the user-set password is cleared, and all existing data in the encrypted partition is erased. The device automatically locks when the computer is turned off within 30 seconds after unlocking or when disconnected from the computer. After setting the password (6–15 digits), simply enter the correct password to unlock. The built-in battery enables offline key encryption, allowing password setup and input without connecting to a computer.
