A phone lock box with a timer is a practical device designed to restrict access to mobile phones for pre-set periods, helping users manage screen time, reduce distractions, and maintain focus in environments like homes, schools, offices, or travel settings. While such products are often available through e-commerce platforms like Amazon, Shanghai Kuntu Industrial Co., Ltd.—a BSCI-certified manufacturer with over 20 years of experience in security and lock products—produces high-quality phone lock box timers that are suitable for direct purchase, bulk ordering, or partnership with Amazon sellers and retailers. Kuntu’s phone lock box timers combine durable construction, intuitive timing controls, and user-friendly design, making them a reliable choice for individuals, educational institutions, and businesses seeking to promote mindful phone use. Kuntu’s phone lock box timers are engineered with features that prioritize functionality and durability. The box bodies are typically made from high-grade metal (e.g., aluminum or steel) or impact-resistant plastic, ensuring they can withstand daily use (e.g., being placed in backpacks, set on desks) without cracking or breaking. Most models feature a transparent front panel (made from shatterproof acrylic), allowing users to see their phone (e.g., for emergency alerts) while preventing access. The timing mechanism is available in both mechanical and digital versions: mechanical timers use a rotating dial to set periods from 15 minutes to 24 hours, with a clear click when the time is set, while digital timers feature LCD displays, touch controls, and programmable settings (e.g., saving favorite time intervals). The locking mechanism is simple yet secure: once the timer is set, the box door locks automatically, and it can only be opened when the timer reaches zero—eliminating the temptation to access the phone early. Some models also include a key override (for emergencies) that can be used by authorized users (e.g., teachers, parents) to open the box before the timer expires. The application of phone lock box timers is diverse, catering to various user needs. For example, a student preparing for exams may use Kuntu’s phone lock box timer to set a 2-hour study session: they place their phone in the box, set the timer, and focus on studying without the distraction of notifications. After the timer expires, the box unlocks, allowing them to check messages. A teacher, meanwhile, may purchase multiple Kuntu lock boxes for their classroom, using them to store students’ phones during tests or lectures—ensuring no cheating and maximum attention. For families, a Kuntu phone lock box timer can be used during dinner or family activities, encouraging everyone to disconnect and engage with each other. For Amazon sellers, Kuntu’s phone lock box timers represent a high-demand product: the company offers bulk pricing, custom packaging (to meet Amazon’s FBA requirements), and compliance with safety standards (e.g., FCC for electronic timers), making it easy for sellers to stock and sell the product on the platform. Kuntu’s commitment to quality ensures that every phone lock box timer meets strict standards. All products undergo testing for: - Timer accuracy: Verification that the timer opens within ±1 minute of the set time. - Durability: Simulated drops and impacts to ensure the box remains intact. - Lock security: Testing to confirm the box cannot be opened without the timer expiring or a key (if included). - Safety: For electronic models, testing to ensure compliance with electrical safety standards. Kuntu’s foreign trade team is equipped to assist Amazon sellers and retailers with all aspects of the partnership, including product customization (e.g., adding brand logos), shipping logistics, and documentation (e.g., safety certificates). If you are an Amazon seller looking to stock phone lock box timers, or an individual interested in purchasing one, please contact our team to learn more about product availability, pricing, and shipping options.

Useful Time Lock Box for Managing Screen Time

I bought this time lock box to limit my kids’ tablet use. I set the lock for 1 hour, and they can’t open it until the time is up. It’s easy to set the time, and the display is clear. The box is sturdy, so they can’t break it open. It’s also helpful for me to limit my own phone use—great for family time management.

User-Friendly Time Lock Box for Snacks

I use this time lock box to store snacks so I don’t eat them too often. I set it to unlock only after I finish my work, which helps with self-control. The time setting is intuitive, and the box is easy to clean. It’s also small enough to fit in my kitchen cabinet. I’ve recommended it to friends who struggle with snacking too much.
