Product Description

Product Description

Portable DJI Mavic 3 Tether Drone Ground Power Station with 33m 55m Auto Reel In/Out Tether Cable

      The tether power supply system can perfectly adapt to the DJI Mavic 3 drones, integrating UAVs with a ground-based power station through a durable tether cable, delivering continuous electricity to enable extended flight operations. This innovative solution eliminates battery limitations, allowing drones to perform prolonged missions without interruptions - dramatically improving operational productivity. This system ensures that the drone can carry out surveillance, mapping, emergency communication and other tasks at high altitude for a long time through stable power supply.

Function characteristics

1). Cable reel in&out function: Passive wire reel out, long press the button to automatically reel in cable, and backup battery to activate cable reel in function in case of power cut off.

2). Protection function: Separate design for strong and weak electricity. Input overvoltage and undervoltage protection. Output overvoltage, overcurrent, short circuit, over temperature protection, fault elimination and self recovery.

 3). Equipment portability: With a backpack design, the backpack can be equipped with a complete tethering system that includes a tethering box, onboard power supply, and other accessories. The overall weight is 5.0 ± 0.2kg. 

4). 1800W/3500Wh outdoor mobile power bank or 1200W/2.5L generator is recommended.
