I found this inexpensive and feature laden 8x port smart USB charging station with LCD, Over Heat and, Over Charging protection.
I have found this to be the best option for charging multiple cameras at the same time in one location.
At least it is for me.
I recommend it. Even though it’s max output for each USB port is 12v-2.4watts. I think it’s close enough and provided overcharg protection

Let me know what you all think.
I plan to have 12 outdoor cameras running on 3 base stations in the future.
I think this would help me recharge them all when the occasion arises.
