Key Features

• Wide Compatibility: Fits most standard smartphones with an inner chamber of 170×83×16 mm. Not compatible with foldable phones or devices exceeding the inner dimensions. Very thick cases may need to be removed before placing the phone inside.
• Ultra-Long Battery Life: After a full 2-hour charge, the box operates for up to approximately 90 days on standby — and up to ~50 days in active use. The built-in 3.7V mainboard automatically unlocks the box once the timer expires, so you never have to manually intervene.
• Flexible Time Settings: Use the LCD display to set a lock duration from 1 minute up to 99 hours and 59 minutes. A convenient 5-second "hesitation period" after confirming your time lets you cancel if needed before the lock engages.
• Emergency Unlock: For genuine emergencies, the box includes a limited emergency unlock function — available up to five times total. Use this feature wisely and plan your lock durations accordingly.
• Stay Reachable: A dedicated earbud access port lets you keep your earbuds connected so you can still answer important calls even while your phone is locked away.
• Compact & Portable Design: Lightweight construction with outer dimensions of 215×95×24 mm makes this lock box easy to take to the office, library, or anywhere you want to stay focused. Includes a USB charging cable and user manual.
