Battery pack
It is a good idea to have a battery, especially when you travel with your
computer. This greatly increases your productive range when you are
on the move.
AC adapter
Having a spare AC adapter allows you to keep one in two different
places. For example, you could have one AC adapter at home and
another at work. This means that you don't have to carry an AC
adapter when traveling between your two base locations.
