Will the Wolfbox G900 Drain My Battery? Internal Bench Test Results & Low Voltage Cutoff

Wolfbox G900 & TriPro OBD Hardwire Kit (WBH40O) | Technical Stress Test & Power Draw Data

We don't just sell dash cameras; we thoroughly test our range so that we can be the specialists you deserve when you call or email us for advice. This post contains our internal raw data. Whether you are a DIY enthusiast or just want to see the depths we go to for testing, we hope this helps.

Technical Overview: WBH40O Kit

  • Compatibility: 12V (Cars) / 24V (Trucks & Vans)
  • Output: 5V at 4A
  • Working Temps: -30C to 70C
  • Connection: Pin #16 (Constant B+) and Pin #4 (Ground)

Cut-Off & Low Voltage Protection

This kit features a built-in voltage cutoff sensor. It detects when your car battery drops to 11.8V and automatically kills power to the camera.

Technical Note: In our testing, we noticed a +-0.3V tolerance. During one bench test, we experienced a full shutdown at 12.1V. This is critical if your battery is older; the 11.8V threshold is fixed and cannot be adjusted on this specific kit.

Power Draw & Recording Modes

We bench-tested the Wolfbox G900 V2 to see exactly how much power it pulls while driving vs. parked:

Mode Current (Amps) Power (Watts)
Normal Driving (1-CH) 0.63A ~8W
Time-Lapse Parking 0.31A ~3.8W
Impact Parking Mode 0.004A <0.1W

G-Sensor Parking Mode

In this state, the unit essentially shuts down to an ultra-low-power state at just 0.004A. Only the G-sensor stays awake. If it detects an impact, it wakes the unit and records for 20 seconds before returning to sleep.
