I've used one a few times, you're kind of planning on just pouring a lot of beers. When do you pull it again? When you get frustrated your beer isn't full yet. One of the mini regulators is probably a better option, but the nice thing with the charger is you can lay it flat along the top of the keg (hopefully protected by the keg handles, etc. I'd watch out if you're using a picnic tap, you can definitely over pressurize and start gushing beer out without opening the picnic tap.
