Since I live in earthquake country, my solar system consists of a Yeti 1250 by Goal Zero. I also have two 30 watt solar panels and one 300 watt solar panel. The Yeti 1250 has Anderson Powerpole for both charging the unit and attaching things like CB or Ham radios. a 12 volt "cigarette lighter" type plug (i know I am aging myself calling it that), 3 USB and three 110 volt outlets. I have used this in many camping trips and Amateur Radio Field Days. It is a work horse. However, it isn't the lightest thing on the planet as it weighs over 100 pounds.
