There are actually three different saws that are cordless 18v. They have a trim saw, the regular size cordless circular saw, and the 24v model. The trim saw I don't like and it only good for that, trim work and cutting 2x4's and 2x6's. The regular size cordless saw has the power and the ability to cut through anything your regular corded saw will. The 24v is the same as having a very good worm drive circular and will cut through anything and last a long time.
