A high-capacity 50-slot triple-tier centralized phone charging management solution for schools, large enterprises, government institutions, and tender projects — maximizing space efficiency with a vertical high-density design.
Devices: Smartphones, small power banks, and USB-charged devices under 8 inches.
LK-PH50 is a triple-tier vertical charging locker achieving 50 slots at 790mm height — the core model for school and large-institution bulk management. Three independent charging systems deliver 500W total power, covering full-load fast charging for all 50 devices. The tempered glass door, side ventilation slots, and industrial-grade cold-rolled steel structure ensure stability and safety under long-term high-frequency use. The vertical design maximizes space utilization, ideal for placement against walls or in corners.
3-tier vertical structure achieves 50 slots within 790×580×270mm height — a single unit covers an entire class or department.
Three independent charging systems deliver 500W total — ensures no power bottleneck for simultaneous QC fast charging of all 50 devices.
Made of thickened cold-rolled steel with electrostatic powder coating — purpose-built for long-term high-frequency school and institutional use, balancing durability and pry resistance.
Tempered glass door allows device inspection without opening — balancing visual management, security protection, and long-term durability.
Side ventilation slot design with internal convection channels for effective heat dissipation, ensuring stability during extended full-load operation.
All 50 slots across 3 tiers separated by ABS flame-retardant engineering plastic dividers — resistant to ignition and spread, enhancing overall safety.
Applications
For grade-level or school-wide centralized phone management, suitable for exams, classrooms, and boarding management.
For meeting rooms, training centers, and employee service hubs in corporate HQs or large branches.
Suitable for educational equipment procurement, government project tenders, and other bulk scenarios requiring high capacity.
For centralized phone storage in standardized exams, professional certification tests, and similar scenarios.

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 500W 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.
Device Compatibility
Compatible with all major smartphone brands (iPhone, Samsung, Google Pixel, Xiaomi, Huawei, etc.) and small USB-charged devices.
Each slot supports up to 160×22×230mm, accommodating phones under under 8 inches and standard power banks.
