Looking for a portable battery 10-20,000+mah which can take a charge from USB C or MicroUSB and has at least 1 or 2 USB A outputs with UPS functionality.
In short I want to run a solar panel such as those eufy panels, to a battery and from that battery run 2-3 of those Xiaomi/Tapo 360 cams, solar panel will load up the battery during the day and then the cameras can draw down during day and evening (this is the theory anyway)
Things to note is the cameras do not have any onboard battery so the UPS function is a must as it needs to seamlessly be able to draw from solar and battery, I know the bluetti’s and all those do these functions but hoping for something smaller.
Only power requirements I can find for the cameras is 5V/1A
Somehow I don't think a 20,000mAh battery will run provide power for 2-3 cameras simultaneously for more than 2 or 3 hours. I guess that's fine if you really only need the cameras powered in the evening and not all night.
Your other issue is depending on the weather and time of year, the solar panel may not generate enough power to fully charge the battery while also powering those cameras during the day.
