Using Wyze Cam with USB Power pack, due to construction theft (no electricity)

A V2 camera draws about 310 mA in Day mode, and 430 mA in Night mode with the IR LEDs turned on.

Your 22,000 mAh power pack will get you around 70 hours of runtime without the LEDs. Around 50 hours of nighttime runtime (and presumably you’ll want the LEDs on to catch the midnight marauders).
