Canadian Tire. Spend about $60+ on one. Make sure it does at least 10amps (in whatever setting) @ 12-14 volts. Higher amps if you want to run your sound system at full tilt on it only.
Smart Charge ones charge and then turn off to not overcharge the batt
Manual charge ones keep feeding power and can cause a battery to overheat.
A Smart Charge 2 amp will do you all day if you just have your flashy lights on.
Smart Charge 10-12 amp if you are running a fairly loud sound system...but your batt will get hot over extended periods of use.

Also remember......

Bring a "good" extention cord with a Grounded end to it (3 prong) 25 foot+
No ghetto lamp cords ppl. Unless you feel like causing a fire.

10 amps doing down a wire the size of a twist tie = Flames

I will be coming in on the Sat morning
