I want to buy a battery that be be discharged and charges at the same time, to power a tiny computer plus the computers screen 24/7 so other than the port for input power from the solar panel, it would need a minimum 3 USB ports.
There are lots of batteries like this. But the place I need to run it has horrible winters and it will get down to maybe -15F at worst. So the night will be long and cold and the computer will still need to run through the night. What kind of battery is one supposed to buy for this type of area? What do Alaskans buy which also has 3 USB ports on it?
