This isn't made by Anker. They use Anker's battery technology. They show 4 cells in the expanded view. Let's say (generously) that that's 20,000 mAh at 5V. Tha

This isn't made by Anker. They use Anker's battery technology. They show 4 cells in the expanded view. Let's say (generously) that that's 20,000 mAh at 5V. That gives an average power consumption usage of 11 milliwatts. HD sensors use ~200mW, so that requires the sensor to be off at least 95% of the time to survive a year.
