Works as expected powers 4 cameras just fine

Posted by a reviewer on Amazon

I had many single power supplies one for each camera it took several power strips and made a big mess

I gave these power supplies only a fourstar rating for a couple of reasons first they dont have a ul certificaton and second i have not tested them against all of their specifications so their compliance is unknown

The load imposed by these four cameras is approximately 0

Apparently the voltage does not drop enough at any time to noticeably upset the operation of any of the cameras

The power supply is situated in an area having a controlled ambient temperature of approximately 65f and whenever ive checked it the case of the power supply has not even felt warm unlike the 3amp wall wart power supply that i previously used with only two of those cameras which became quite warm or even hot under the same ambient temperature conditions
