I'm wanting to see if anyone has had any thoughts on this. I'm looking to get a generator from honda but a good used one is still $900. I can do the same with 2 dry cell batteries and a Big A$$ power invertor. $400. I plan to use it for tailgating which will be at bestbe running a tv and a direct tv box. I will need it to get about 4-5 hours at most. My little invertor will run all day on 1 battery and thats charging my laptop. Any thoughts?
