There are cameras with built-in batteries and mobile power supplies powered by power banks. However, the volume of its own power supply is a little large, the endurance is not strong, and the cost of using a charging bank is a little high. It is best to find the nearest power cable in the past, if it is only powered to monitor, find a general fine power wire on the line (because the monitoring power is small, the wire requirements are not high).

First of all, the power of the charging treasure is limited, and its own non-renewable energy, only constant charging can keep the power of the charging treasure sufficient. And the charging treasure charge and discharge I have a certain number of times, after reaching it can no longer be charged

Secondly, the camera works, and its power consumption will continue to lose the power of the charging bank! Long-term use can not be used normally!
Yes, I am using it now, the charging bank is connected to the charger, and the camera is connected to the discharge terminal. I use a 1000 mah charging bank, which can last about 8 hours without power
Of course, you only need the output power to provide to the camera
