    Hello All

    I am wanting to build a power pack box consisting of a 150w 12v to 220v inverter and an SLA.

    1) The inverter will only be in use via the cigaretter lighter in my car when the engine is running.

    2) The SLA will be 12v - to charge lets say a cellphone whilst camping and maybe little USB speakers etc. And possible an emergency light source

    My questions are: 1) What amperage rating SLA should I use?
    2) Should I install a computer type fan in the box for extra cooling?
    3) what kind of lightng should I opt for??

    I really hope you can advise me
