You might consider something like this:
I have one and find it very well designed.? It has separately switchable 12V and 120VAC (600W) outputs, and a capacity of 250WH. It includes an input for a 12V solar panel for charging (standard XT60 connector) and also has a built in 120VAC charger that is VERY fast.? It can charge it from dead to full in about an hour or less. The front panel displays state of charge and also predicted run time at the current discharge rate.
