With 11 years of manufacturing experience, we understand the "battery anxiety" often experienced on construction sites. The A4 series is equipped with a high-definition LCD display that tracks battery power with 1% accuracy, allowing you to clearly see the remaining charge and estimated working time at a glance.
No more guessing the remaining runtime based on blinking indicator lights. During charging, the display shows real-time progress from 0% to 100%, ensuring you are never interrupted by unexpected power loss in the middle of a task.
Powered by a built-in 3000mAh rechargeable lithium battery, the unit supports simultaneous charging and operation. It can also be powered via a power bank for an instant boost, providing reliable support during high-intensity work.

3. Robust Protection & Precise Self-Leveling System
The entire product series is built with a durable and robust structure.
The 8-line model combines aluminum alloy and engineering-grade plastics and is rated IP54. The 12-line model uses an aviation-grade aluminum alloy base with an IP55 rating and can withstand drops from up to 1.5 meters. The 16-line model offers enhanced impact resistance with an IP65 rating and operates reliably in temperatures ranging from -20°C to 50°C.
Each model is equipped with a high-precision self-leveling system with the following characteristics:
• 8-Line: Magnetic-damped pendulum system with a self-leveling range of ±3°, achieving leveling within 3 seconds.
• 12-Line: Magnetic-gravity self-leveling system with a range of ±3.5° and an additional manual lock mode.
• 16-Line: Dual-axis magnetic-gravity compensation system with a ±4° leveling range and 0.01° accuracy. The laser automatically shuts off if the device is tilted beyond the leveling range.
The entire series is certified under CE and CMC standards and complies with the GB 7247.1 laser safety standard, ensuring safe and reliable operation.
4. Intelligent Control & Long-Lasting Battery Performance
The 12-line models and above come with a wireless remote control, allowing operation within a 10-meter range. The touch control panel supports independent switching of laser lines (zone control) and includes digital calibration memory, eliminating the need for repeated adjustments after initial setup.
Battery performance:
• 8-Line: Single 3000mAh battery; over 4 hours of operation with all lines active, or over 8 hours with a single line. Supports fast charging, reaching full charge in approximately 2.5 hours.
• 12-Line: Dual-battery system with a total capacity of 6000mAh; provides over 8 hours of continuous operation with all lines active. Supports fast and parallel charging.
• 16-Line: Dual-battery system; provides over 6 hours of operation with all lines active.
Standard accessories include the main unit, batteries, charger, remote control, wall-mount bracket, and storage case. The device supports self-calibration every three months, and calibration data is stored automatically to maintain long-term accuracy.
