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 200W 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.
