The main difference between a charge card and a credit card is that a credit card does not have an established credit limit, whereas a credit card does. To decide whether or not a charge on the charge card will be approved, AMEX will automatically consider a number of factors for every charge, and make a decision on whether or not to approve it each time. In contrast, a credit card has an established limit, and once you exceed that limit, the creditor will decline the transaction (although creditors do sometimes allow you to exceed your credit limit, with a fine for going above your limit).
