A 30-slot dual-tier centralized phone charging and secure storage solution for school grade-level groups, corporate departments, large retail stores, and public service institutions — balancing capacity with space efficiency.
Devices: Smartphones, small power banks, and USB-charged devices under 8 inches.
LK-PH30 marks the transition from desktop-class to floor-standing capacity in the charging locker series. The dual-tier structure achieves 30 independent slots within just 610mm of height, balancing space efficiency with operational convenience. Each tier features an independent USB charging module with a total output of 300W. The tempered glass door replaces acrylic for enhanced security and durability. Suitable for classrooms, offices, and back-office areas that need higher capacity within limited space — can be placed on desks, countertops, or dedicated stands.
2-tier structure achieves 30 slots within a compact height of 610×460×270mm, balancing high density with daily operational convenience.
Each tier features an independent USB charging module with 300W total output — supports full-load simultaneous fast charging for all 30 devices.
Made of cold-rolled steel with electrostatic powder coating — built for long-term high-frequency use in schools and institutions.
Transparent glass door allows device status inspection without opening — more scratch and impact resistant than acrylic, paired with key lock for asset security.
Each slot individually separated by ABS flame-retardant engineering plastic dividers — prevents collision and scratching, supports numbered management.
Side ventilation slot design promotes air convection, reducing internal temperature during extended operation and extending charging module lifespan.
Applications
For grade-level teacher offices to centrally manage student phones, suitable for rotating-class or boarding school scenarios.
For departmental device management, ideal for ~30-person team meetings or daily phone storage.
For standardized staff device management in government service centers and public-facing units.
For staff break areas and shift-change device management in large stores or warehouse retail.

Product Structure and Details
Tough ABS slots hold phones upright — better cooling, easy access.
Magnetic latch keeps the door firmly shut — no swinging from wind or bumps.
Ventilation openings improve airflow for cooler bulk charging.
● Low-Voltage Safe Output: 5V low-voltage output per port — well below the human body safety voltage threshold.
● Overload Protection: When total load exceeds the 300W safe range, the system automatically limits current.
● Short-Circuit Protection: Provides instant protection under abnormal short-circuit conditions.
● Flame-Retardant Materials: Slot dividers use ABS flame-retardant engineering plastic — resistant to ignition and flame spread.
● Auto Power-Off: Automatically stops charging when device is full, preventing overcharge and extending battery life.
● Cabinet Grounding: Metal body design supports grounding, compliant with international electrical safety standards.
