​Here is a breakdown of the standard technical specifications and features for this model, optimized for clean product descriptions or listings:

​Key Specifications

• ​Model: AL-7120 / AL 7120
• ​Light Source: High-brightness SMD LED beads (provides an energy-saving, wide-angle floodlight effect).
• ​Battery Capacity: Typically equipped with a high-capacity 4V rechargeable lead-acid or lithium-ion battery (approx. 1600mAh to 2400mAh depending on the exact factory batch).
• ​Charging Input: AC 220–240V, 50/60Hz (standard wall outlet charging).

• ​Backup Duration:
  • ​Strong Light Mode: Up to 2–3 hours of continuous high brightness.
  • ​Weak/Dim Mode: Up to 6–8 hours of low-intensity backup.

​Major Features

• ​Dual Lighting Modes: Built-in switch toggles easily between high intensity (maximum illumination for broad space coverage) and energy-saving low mode (extends battery runtime during long power cuts).
• ​Automatic Emergency Activation: When plugged into a live wall socket with the switch turned "ON", it will automatically light up the moment the main power fails.
• ​Portable Design: Features a built-in retractable handle or hook slot, making it equally effective as a stationary desktop lantern, a wall-mounted emergency fixture, or a portable hand lamp.
• ​Built-in Protection Circuit: Includes automatic overcharge and over-discharge protection to protect the battery cell from swelling or premature degradation.

​Important Maintenance Tip: To maximize the lifespan of the built-in rechargeable battery, always charge the unit at least once every 2–3 months if it sits unused for long periods. Never let the battery completely drain out to 0% for weeks at a time.
