A 40-slot dual-tier wide-body centralized phone charging management solution for schools, enterprises, large institutions, and bulk procurement projects — meeting large-scale management needs with higher density.
Devices: Smartphones, small power banks, and USB-charged devices under 8 inches.
LK-PH40 expands horizontally from the 30-slot model to 580mm width, offering 40 slots across two tiers — an efficient choice for school and enterprise bulk deployment. Each tier's 20 slots are powered by independent USB charging modules with 400W total output for full-load stability. The tempered glass door with side ventilation slots balances visual management, heat dissipation, and asset security. Suitable for medium-to-large deployments exceeding 30 devices.
2-tier structure achieves 40 slots within a compact height of 610×580×270mm, balancing high density with daily operational convenience.
Each tier features an independent USB charging module with 400W total output — supports full-load simultaneous fast charging for all 40 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 whole-class or grade-level student phone management, supporting rotating classes and exam scenarios.

For device management in corporate HQ meeting rooms, training centers, and visitor areas.

Suitable for bulk procurement projects with full certification documentation and authorization support.

For device management in vocational schools, language centers, and other centralized training institutions.

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 400W 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.
