Will craftsman trim saw make straight cuts in 2x4?
It is unlikely the saw will cut through in a single pass. This will require flipping the board over to cut the 10% that wasn't cut the first time. The straightest cut will require the use of a saw guide. A simple quick square would be sufficient. Doing a second cut will reduce accuracy as the guide will have to be repositioned. If you are making a cut on a single board the saw you have may work. If you are cutting a lot of 2x4s the saw will quickly use up the batteries. You will need two sets to be productive. Even with two sets you will likely use up the available batteries faster than they will recharge.
