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.
