Real-time power consumption of equipment was 15~17W,voltage was around 7.7V,current was 1.9A~2.3A
Testing Record & Explanation
In the begin: the voltage of D-TAP output was 16.76V (Full voltage 16.8V)
The D-TAP output voltage was 15.99V after 34 minutes , D-tap voltage decline: 12.6%.
The D-TAP output voltage was 15.51V after 1hours & 6 minutes, D-tap voltage decline: 20.6%.
The D-TAP output voltage was 14.19V after 2hours & 26 minutes , D-tap voltage decline:42.6%.
After 3 hours & 46 minutes, the voltage drops to the critical value, the camera maybe shut off very soon.
After 3hours, 46 minutes and 44 seconds, both machine and power meter were shut off. The D-tap port voltage was 9.92V.
The full run time was 3hours & 46minutes.. During this period, the average total power consumption of BMP cc4k camera & power meter was 16W. According to the design capacity 72Wh of Power Handle, 85% of design capacity was usable capacity.
