Unless you're heading out to shoot for National Geographic, you don't want to leave the house with a giant over-stuffed camera bag hanging off your shoulder. Everything you bring has to play a crucial role for your photography outing. Or, better yet, two crucial roles like this padded camera bag divider with a 3,000 mAh battery hidden away inside.

For $40 it not only guarantees that your smartphone doesn't die while it's tracking your GPS location everywhere you're snapping shots, it also ensures that all of your camera's accessories stay separate and compartmentalized in the bag so your lens and body don't get all scratched as things jostle around in there.
