Usual Dji high quality. Better range than standard O4 Air Unit, but both get very hot without airflow from aircraft or a fan if on the bench. The Pro will throttle back to low power when it gets too hot. You need the Dji Googles 3 and Dji FPV remote controller 3 to use the O4 Air Unit Pro.
US Drone shipped promptly and answered the phone when I had questions. Product was sealed and in perfect condition.

DJI Matrice 400 – Professional Grade Power, Safety & Intelligence
The DJI Matrice 400 is DJI’s next-generation flagship enterprise drone—built for long-duration missions, heavy payloads, and demanding industrial environments. With extended flight endurance, advanced obstacle sensing, powerful AI capabilities, and compatibility with the latest DJI payload ecosystem, the Matrice 400 is engineered to raise the standard for public safety, inspection, mapping, utilities, and emergency response operations.
Key Highlights
✔ Up to 59 Minutes of Flight Time
Even with a payload attached, the Matrice 400 delivers up to 59 minutes of forward flight and 53 minutes of hover time, giving teams more time in the air for long-duration missions such as search and rescue, firefighting overwatch, and large-area surveying.
✔ 6 kg Payload Capacity
With four E-Port V2 mounting points and support for single, dual, and bottom-mounted third gimbals, the Matrice 400 can carry up to 6 kg (13.2 lb)—allowing up to seven total payloads simultaneously.
✔ Advanced Obstacle Avoidance
A fusion of ring-scanning LiDAR, millimeter-wave radar, and low-light fisheye vision sensors enables wire-level obstacle detection, even in darkness, rain, fog, or dense environments. This dramatically increases safety during long-range or low-altitude operations.
✔ O4 Enterprise Transmission
Equipped with the new O4 Enterprise Transmission System, the M400 supports:
- Up to 40 km transmission (line of sight)
- Sub-2 GHz band support for enhanced penetration
- Optional Dual Enhanced Transmission Modules for network relay and anti-interference performance
This ensures stable connectivity in urban, mountainous, and remote environments.
✔ Built-In Relay Mode
One Matrice 400 can automatically act as an airborne transmission relay for another drone—ideal for valleys, mountains, maritime operations, or urban canyons.
✔ Rugged, All-Weather Reliability
With an IP55 weather rating and an operating temperature range of -20°C to 50°C, the Matrice 400 remains operational in rain, snow, dust, desert heat, or freezing cold.
Payload Ecosystem: Optimized for Every Mission
The Matrice 400 supports DJI’s latest generation of enterprise payloads, enabling unmatched versatility.
