    I'd
          say you need a 3 or 4K. The initial pull of a flash pack as
          the caps empty and it starts recycling is quite high.  Once
          it's recycled it draws almost nothing. You'll need to replace
          fast-blow fuses with higher slow-blows for
            this reason.

          
          And I agree that buying makes more sense.

          
          And you do get some really quiet ones.  They
            are rated for noise and power so you can
              compare them.  Harbor Freight have a good
            selection and great prices.

          I'm trying to calculate how big a generator I
            need to do some location work.   I need to power 4x2400 w/s
            packs and a 2000 w/s pack with over head to charge 2 ranger
            batteries at a time and 2 Leaf batter packs at a time. that
            later items are only 3v.    So I can just rent huge but Im
            trying to rent as physically small and quite as possible.  
        
        
        Quiet might be an issue, but I would not rent. If you are
          ever going to need a generator again, just buy one. NOw that
          Y2K is over, they have become much cheaper. 
        

        The two issues are noise and the size of the gas tank. Most
          portable-ish wheeled generators only have a one gallon or so
          gas tank good for and hour or two. As for quiet, there is no
          such thing as most generators run almost straight pipes. The
          sound can be directed however, and exhausts can be pointed
          away from your set. 
        

        I put a 4” thick styrofoam 3-sided box around mine and run
          longer extension cords for quiet. I don’t think your
           generator needs to be much more than a 2kW generator.
