2. Deep Dive into Key Parameters

The following data is based on laboratory standard test environments, providing a clear comparison of core performance across the three models:

⚖️ Weight and Portability

  • Air mini2: Weighs 18g. The lightweight design is its core advantage—adding negligible burden to assets, ideal for adhesion or hanging on various light-weight objects.

  • Air Pro2: Weighs 25g. Controls weight effectively while maintaining robust protection, suitable for most medium-sized materials.

  • Air Sun2: Weighs 26g. Slightly heavier than Pro2, but offers higher positioning accuracy and energy harvesting efficiency—ideal for high-value assets.

☀️ Power System and Light Harvesting Efficiency

  • Air mini2: Peak power 90mW, conversion efficiency 19%, micro-light threshold 3000lx. Suitable for well-lit outdoor environments.

  • Air Pro2: Peak power 120mW, conversion efficiency 21%, micro-light threshold 1000lx. Broader adaptability—can operate stably even in slightly dimmer lighting.

  • Air Sun2: Peak power 160mW, conversion efficiency 23%, micro-light threshold 300lx. Flagship-level light harvesting capability ensures efficient operation even in extremely low light (e.g., near windows indoors, under tree shade).

📍 Positioning Accuracy and Satellite System

  • Air mini2: Uses GPS satellite hybrid positioning, with outdoor accuracy around 5 meters. Meets basic anti-theft and trajectory tracking needs.

  • Air Pro2: Uses GPS satellite hybrid positioning, outdoor accuracy optimized to 3 meters. Offers more precise location data than Air mini2.

  • Differentiated Features: Air Pro2 and Air Sun2 feature deeper optimization in positioning frequency and scenario-specific algorithm tuning to meet professional and flagship-grade usage requirements.

3. Scenario-Based Selection Recommendations

To help users quickly match their needs, refer to the following decision logic:

1. What is your lighting environment like?

  • Abundant light (mostly open outdoor areas):
    👉 Air mini2 is sufficient—the 90mW power output can maintain energy balance, and it’s the lightest option.

  • Moderate or variable light (frequent shade, near windows indoors, overcast conditions):
    👉 Consider Air Pro2, whose 1000lx micro-light threshold offers better adaptability.

  • Dim or highly unstable light (long-term indoor diffused light, heavy obstruction):
    👉 You must choose Air Sun2, whose 300lx extreme micro-light harvesting capability is essential for continuous operation.

2. How high is your positioning accuracy requirement?

  • Standard requirement (5-meter accuracy is enough, e.g., locating approximate position):
    👉 Air mini2 is the best value choice.

  • Higher requirement (need more precise trajectory, e.g., 3-meter accuracy):
    👉 Air Pro2 delivers better positioning performance.

  • Extremely high requirement (need 2-meter level precision, e.g., precision asset management, complex environment tracking):
    👉 Air Sun2’s high-accuracy BeiDou positioning is the only viable option.

3. Is your environment harsh?

  • Ordinary environment (urban commuting, regular outdoor use):
    👉 Air mini2’s IPx7 protection is fully adequate.

  • Harsh environment (exposure to water, dust, strong vibrations, frequent pulling):
    👉 Choose Air Pro2 or Air Sun2 without hesitation. Their IP68 protection and 20KG tensile-resistant lanyard holes ensure reliable safety.

4. Summary
